500,460,466,459,449,448,439,439,566,565,550,539] O hotel Jangadeiro da capital
pernambucana, Recife, volta a sediar a final do campeonato brasileiro nacional
de xadrez, na sua edição 89. São, nesta oportunidade, cento e oitenta e
três participantes, incluindo oito grandes mestres: uma prova excepcional. A
primeira rodada, realizada com adversários com grande diferença de rating,
não teve surpresas, e todos os favoritos a ganhar o título conquistaram o
ponto. O atual campeão, grande mestre Alexandr Fier, voltou na oportunidade a
um dos seus grandes amores da juventude: o venerável Gambito de Rei, que foi
enfrentado pelo potiguar Alexandre Soares de Macedo com a mais clássica das
réplicas, 2...exf4 3.Cf3 g5. Que aconteceu? A seguir} 1. e4 e5 2. f4 {[#] Nas
minhas bases há não menos de quarenta partidas oficiais com Alexandr jogando
Gambito de Rei -embora ele deve ter jogado muitas mais que isso, uma abertura
da era romântica que se presta muito bem às habilidades táticas do atual
campeão brasileiro. Mencionada no manuscrito de Gottingen, analisada por Ruy
Lopez e Salvio, favorecida por mestres do ataque como Anderssen o Morphy, na
atualidade não é tão comum nos torneios da elite, mais que nada por uma
questão prática as brancas precisam de uma memória enciclopédica para
lembrar centenas de detalhes em cada uma das innúmeras linhas que as pretas
podem se opor. (MI Luis Rodi)} exf4 {A forma mais clássica de enfrentar o
Gambito. As pretas podem também declinar a ferta com 2...d5 ou 2...Bc5, mas
um verdadeiro cavaleiro jamais vai rechazar um reto em uma linha de abertura
tão histórica quanto esta! Ainda quando Fier mostra estatísticas nesta
posição que o deixam perto do oitenta por cento de efetividade. (MI Luis
Rodi)} 3. Nf3 {Esta é a principal preferência do condutor das brancas,
porém também tem empregado a opção 3. Bc4, favorita de Fischer e Judith
Polgar, embora hoje talvez não esteja no melhor momento teórico. Em todo
caso o último jogo de Alex com o lance do bispo foi em 2016. (MI Luis Rodi)}
g5 {Alexandre segue no estilo mais clássico, revivendo a continuação de
moda do século XIX. Sempre observei este lance como uma ideia agressiva das
pretas, mais que uma forma de defender o peão. As brancas, claro, podem
responder de forma mais agressiva ainda, com ideias como 4.Bc4 tentando sorte
no Muzio, e o mesmo Fier experimentou também com a variante Quaade, 4.Cc3,
não menos selvagem, ou a ideia de Rosentreter, 4.d4. Porém a que segue é a
linha principal, algo mais sólida. (MI Luis Rodi)} 4. h4 g4 5. Ne5 {Best by
test. Que eu saiba, Fier nunca experimentou com a linha de Allgaier, 5.Cg5.
Depois do salto de cavalo ao centro, as pretas dispõem de uma grande
quantidade de opções. 5...Cf6 é a mais clássica, embora muito complicada,
enquanto a que segue é uma moderna recomendação teórica, prometendo um
equilíbrio sem muito risco para o segundo jogador. (MI Luis Rodi)} d6 6. Nxg4
{C39: King's Gambit Accepted: 3 Nf3 g5 4 h4.} h5 {[%eval 16,26] Porém este
lance é uma raridade (varinate do Látigo Longo [5. h5]. A linha teórica

segunda rodada, onde alguns dos favoritos deixaram pontos no caminho. Foi o
caso do GM André Diamant, que alcançou uma posição estrategicamente ganha
ante ao representante do Amazonas Suan Bruno Fernandes Lira, para depois
realizar um sacrifício de aparência positiva, mas que só dava certo para
alcançar uma posição equilibrada. Um grande resultado para o enxadrista
amazonense. Os GMs restantes venceram com mais ou menos clareza, formando
parte dos até aqui 32 líderes da prova com 2 em 2. Dentre as partidas da
rodada destaco o seguinte trabalho técnico do GM Krikor Mekhitarian, em uma
catalã modelo. Vale mencionar que esta rodada foi a primeira das duas rodadas
programadas do dia.} 1. d4 d5 2. c4 e6 3. Nf3 Nf6 4. g3 {[#]} Be7 (4... dxc4 {

em c4, quando a denominação de Catalã fechada vale. Do meu ponto de vista,
essa denominação casa mais com os esquemas onde as pretas jogam a linha ...

semi-aberta. A posição que surge é oprincipal palco de batalha no nível

9. Nbd2 {[%eval 13,32] Se as brancas desejam conservar as damas, lances como 9.
Dd3 ou 9.Da4 são possíveis, mas o lance do texto leva a uma típica
posição catalã onde as chances brancas são algo melhores, devido a: a) a
maioria de peões centrais, que oferece uma vantagem de espaço ao tempo que
tira casas das peças adversárias; b) a coluna c é um problema para as
pretas, fundamentalmente no que faz ao seu peão em c7. Neste tipo de
cenários o cavalo em c6 se revela pouco flexível. c) os bispos brancos são
mais ativos que as suas contrapartes pretas, sobretudo o bispo catalã. Por

-180,-196,-194,-190,-194,-181,-181] As 20 horas do passado 14 de dezembro o
árbitro principal da prova, o internacional Igor Macedo -ademais, presidente
da Confederação Brasileira de Xadrez- deu começo á terceira rodada da
prova. Nos primeiros tabuleiros os favoritos enfrentam uma oposição cada vez
mais dura, com duelos entre titulados FIDE em alguns casos. Nenhum dos até
então líderes não possui, ao menos, o título de MN. Passadas as duas
primeiras horas da rodada, ainda não tinhamos definições nas nove primeiras
mesas, que albergam aos sete grandes mestres na liderança mais os fortes MIs
Diego Di Berardino e Roberto Molina. E a mesma situação se mantia após mais
uma hora, pelo que podiamos falar de uma rodada de grande competitividade. As
primeiras partidas em se definir foram as que tiveram a vitória do grande
mestre Luis Supi -ante o MN Yago Labussiere, em uma linha pouco usual da
Siciliana Clássica- e de seu colega Renato Quintiliano ante o MF Charles
Gauche. O catarinense empregou uma duvidosa abertura -1,d4 d6 2.c4 e5 3.Cf3
f6- e após ficar rapidamente em posição inferior nunca se recuperou. A
rodada registrou um bom empate do MF Eduardo Marra ante o GM Krikor
Mekhitarian, e também do MN Andrey Souza Neves ante o GM Darcy Lima;
vitórias com suspense dos grandes mestres Alexandr Fier e Yago Santiago ante
os MN Mateus Tomiello e Matheus Ribeiro, respectivamente. Derrota do GM
Everaldo Matsuura ante o MN Mario Fiaes, outra das surpresas da rodada.
Quatorze líderes após a terceira rodada! Entre eles o mestre internacional
Nathan Filgueiras, protagonista do nosso jogo do dia. Um jogo de 107 lances!}

Esta jogada, explorando o fato das pretas não terem jogado ...b5 em ordem de
restringir os cavalos, é a mais usual, e ademais a recomendação teórica.}
Rb8 $5 {[#] Um lance de espera útil, planejando observar a disposição que
adotem as peças brancas antes de desenvolver a ala de rei. Foi introduzida na
prática pelo enxadrista francês Asher Glicenstein, e ganhou popularidade ao
ser utilizada por Teimour Radjabov na olimpiada de Turin 2006.} 9. a4 {As
brancas tomam medidas contra a possível expansão lateral preta ao custo de
um ligeiro enfraquecimento da casa b4. O lance é o segundo em popula- ridade
na prática, somente detrás da linha 9.Cd5 Bxd5 10.exd5 Cce7 que é ademais a
recomendação teórica.} Nb4 $5 {[#] Este lance, já empregado por
Glicenstein nas primeiras partidas com esta linha no começo do século, é
hoje o mais habitual na prática. As pretas exploram de ime- diato o lado
negativo do anterior lance branco, preparadas para lutar pelo domínio da casa
d5. As brancas podem cortar de raiz o dilema ocupando esse ponto, porém
então uma oportuna troca elimina os riscos associados com um peão fraco em
d6 e a casa igualmente fraca em d5.} 10. Nd5 Bxd5 11. exd5 Nf6 12. Ne3 {
O lance mais natural, o mais utilizado na prática, porém... permite um
cômodo equilíbrio ao segundo jogador.} ({Talvez as brancas pudessem pensar em
} 12. g3 {[Martinez - Suárez, Espanha 2021] e se} Nbxd5 13. Bg2 $44 {onde a
sua compensação parece mais que adequada. As pretas, claro, podem escolher
não capturar de imediato em d5.}) 12... Qa5 13. Bd2 Qc5 14. c4 a5 $5 {A
Filgueiras lhe incomoda a ameaça estratégica do a5 branco, considerando que

fruto de uma avaliação pobre da posição resultante -como poderemos
observar, as ações na ala de dama se revelam funcionais aos interesses
pretos-. As brancas poderiam ter criado sua própria agenda no outro setor do
tabuleiro mediante 15.Df3!÷ planejando avanços de peão no setor. A
posição seria então de duplo gume} Ne4 16. Bxb4 Qxb4+ 17. Qxb4 axb4 $17 {
[#] Depois da troca de damas aparece uma posição onde as chances do segundo
jogador devem se considerar superiores. Ambos lados contam com bispos maus,
porém o das pretas dispõe de circuitos interessantes para transitar. A
estrutura de peões, apesar dos dobrados na coluna b, é também algo melhor
para as pretas: oferece uma excelente base para o cavalo em c5 ao tempo que na
ala de rei a maioria de peões é flexível e pode ser avançada com
facilidade -o que não é certo para a maioria branca no setor oposto-.} 18. b3

foi-se mobilizando, ganhando espaço e abrindo linhas para o bispo, que cada
vez é menos mau. Uma comparação entre as peças menores de um e outro lado
mostra que a vantagem preta está perto de ser decisiva, restando somente a
execução de um plano de concretização.} 23. Rh3 {Ameaçando o peão de b4

enxadristas com cada vez menor diferença de rating elo, o que a sua vez
deriva em jogos mais combativos e parelhos. Um dos melhores espetáculos da
rodada aconteceu na mesa 1, onde o jovem mestre nacional Lucas Piccoli dividiu
o ponto com o ex campeão brasileiro e grande mestre Luis Supi. Após uma
Siciliana Clássica onde as primeiras surpreenderam levando sua dama a d3 em
vez de d2 na variante Richter Rauzer, as pretas obtiveram um peão a mais a
câmbio de ter que deixar seu rei no centro do tabuleiro. Perto do apuro de
tempo, algumas imprecisões foram trocadas e depois de uma interessante
entrega de peça de Piccoli todas as peças pretas ficaram reduzidas em um
pequeno espaço. Claramente tinham compensação as brancas. Supi começou a
operação desenrola e quase dá certo. Novas imprecisões e finalmente se
chegou ao reparto do ponto. Ao finalizar a rodada somente cinco são os
líderes da prova: os grandes mestres Alexandr Fier, Renato Quintiliano e Yago
de Moura Santiago -o crédito pernam- bucano-, assim como os mestres
internacionais Nathan Filgueiras e Diego di Berardino, que assinou uma bonita
vitória posicional mostrando o poder do par de bispos em posições abertas.
A rodada registrou ademais um valioso empate do mestre fide Wagner Madeira
ante o mestre internacional Roberto Molina, e o mesmo resultado alcançou o cm
Luciano Zallio ante o grande mestre Darcy Lima. Com sendas vitórias recuperam
posições os grandes mestres Krikor Mekhitarian e André Diamant, se
colocando a meio ponto dos líderes. Na próxima jornada teremos novamente uma
rodada dupla, desde as 14 e as 20 horas. A quinta rodada entrega duelos como
Fier - Di Berardino [mesa 1], Quintiliano - Filgueiras [mesa 2] e Santiago -
Mekhitarian [mesa 3]. Começam os grandes encontros!} 1. d4 Nf6 2. c4 e6 3. Nf3

363,360,368,412,341,29984,29985] A primeira das duas rodadas do dia entregou
partidas sensacionais, de grande luta. Na mesa 1 o grande mestre Alexandr Fier
venceu ao mestre internacional Diego di Berardino em uma Ruy Lopez de
interesse teórico que é o nosso jogo do dia. Fier terminou a rodada como
único líder, já que os mestres que compartilhavam a liderança com ele não
puderam seguir seus passos: na mesa 2 se registrou um lutado empate entre o
grade mestre Renato Quintiliano e o mestre internacional Nathan Filgueiras
após uma interessante Catalã aberta, e na mesa 3 o até então líder, o
grande mestre ernambucano Yago Santiago perdeu em um Gambito de Dama declinado
com cara de Catalã ante o também grande mestre Krikor Mekhitarian. O
condutor das pretas fez tudo bem: obteve iniciativa na abertura com base a sua
maioria de peões na ala de dama, entregou corretamente uma qualidade e impôs
com precisão a sua vantagem. Agora Krikor, Renato e Nathan, ficaram a meio
ponto de Fier. Luis Supi -venceu após lutada partida ao mestre fide Andrey
Souza Neves- e André iamant, que se impôs ante ao mestre fide Wagner Madeira.
Importante vitória do MI oberto Molina ante ao MNl Lucas Piccoli. A surpresa
da rodada foi a derrota do GM Darcy Lima ante ao candidato a mestre Luigy Lira
de Siqueira -representante de Brasília. olina e Lira de Siqueira também se
anotam entre os que correm atrás do líder, a meio ponto.} 1. e4 e5 2. Nf3 Nc6

postergam até ter totalizado o desenvolvimento. Praticamente toda a elite

antigas linhas principais} b5 7. Bb3 d6 8. c3 {8.a4 e 8.a3 também são

seja a quarta em popularidade. Carlsen tem jogado, assim como a opção 9.Te1,
que é a mais usual na prática. 9.Cbd2 e 9.h3 ompletam o leque de opções
brancas nesta posição.} Bd7 {Um lance flexível, defendendo a8 ao tempo que
mantém diversas possibilidades para as peças menores. Foi a escolha do
atual campeão mundial, Ding Liren, nesta posição.} 10. Bc2 {O primeiro
passo para a realização de um futuro d4. As brancas ainda têm que definir a
colocação das peças menores da ala dama -não um tema menor na Ruy Lopez.}

desta peça a g6 seja um plano típico nas aberturas abertas e nesta posição
concreta foi utilizado por mestres como Peter Leko ou Eugeny Tomashevsky, aqui
pode não ser o lance mais preciso, já que as brancas ganham uma interessante
iniciativa no centro. Na prática a mais usual é 13...Tb8 que parece a mais
exata nesta osição concreta. Alguns exemplos desde aqui são: 14.b4 (14.Cf1

Um dos grandes dilemas posicionais na Ruy Lopez, para as brancas, é saber
quando eliminar a tensão na ala de dama com este tipo de troca.

451,441,444,435,232,452,451,391,307,473,450,29992,29993] O empate
relativamente rápido entre os grandes mestres Luis Supi e Alexandr Fier deu
aos que perseguiam ao segundo deles na liderança a chance de alcançá-lo. O
jogo entre os dois primeiros pré-classificados adotou um roteiro pouco usual:
1.e4 c5 2.Cf3 Cc6 3.h3!? O atual campeão nacional compreendeu que teria que
enfrentar um esquema anti-siciliano onde o lance h3 seja parte e se decidiu
por uma formação com fiancheto na ala de rei e saída de cavalo por e7.
Quando a abertura tinha finalizado, entregando um equilíbrio cômodo ao
segundo jogador, Supi ofereceu a divisão do ponto. O resultado da mesa 1
abriu a possibilidade de até três participantes se juntarem ao líder ao
finalizar esta rodada, o equador da prova. Porém passadas duas horas de
começada a rodada as mesas 2 e 3 registraram empates, os do grande mestre
Krikor Mekhitarian com o mestre internacional Roberto Molina, após um Gambito
de Dama variante das trocas onde ambos os mestres fizeram o grande roque, e o
do mestre internacional Nathan Filgueiras ante o grande mestre Andre Diamant
em uma movimentada Siciliana Sveshnikov. Quem sim tomou a chance de alcançar
a liderança com as duas mãos foi o grande mestre Renato Quintiliano, que
levando as brancas ante o candidato a mestre Luigy Lira de Siqueira -que vinha
de dar uma das grandes surpresas da prova na rodada prévia- impus sua
técnica desde uma das linhas de moda na Catalã aberta. É o nosso jogo do
dia. O mestre de Osasco agora compartilha o primeiro lugar com seu colega Fier.
Importantes vitórias do mestre internacional Diego di Berardino e do grande
mestre Yago Santiago, que se recuperam assim das derrotas sofridas nas rodadas
prévias. A de este dia foi a última jornada com rodada dupla. Na sétima
rodada, este domingo 17, terá nas primeiras mesas os enfrentamentos seguintes:
Mesa 1- Fier - Quintiliano em choque de líderes; mesa 2 - Molina - Supi; mesa
3 - Do Valle - Mekhitarian; mesa 4 - Diamant - Labussiere; mesa 5 - Aranha -

mestre começou a prova a meia máquina, mas no tramo final ele está
acelerando e depois de uma convincente vitória levando as peças pretas ante
o mestre internacional Roberto Molina alcançou a liderança. Que será a
partida analisada de hoje. O ex campeão nacional se beneficiou do empate do
atual titular, o grande mestre Alexandr Fier, que na mesa 1 não pode quebrar
a sólida defesa Philidor adotada pelo grande mestre Renato Quintiliano,
apesar que o desenvolvimento da partida foi muito interessante e cheio de luta.
Como é habitual, as pretas ingressaram na variante de Hanham utilizando a
ordem da defesa Pirc, o que tira algumas linhas incômodas que as brancas
dispõem na ordem natural com 1.e4 e5 2.Cf3 d6. Outros dois mestres chegaram
à liderança: o mestre fide Lucas do Valle Cardoso, que obteve uma importante
vitória ante o grande mestre Krikor Mekhitarian em uma Reti onde seu
adversário ficou melhor posicionado após a abertura, porém que depois
foi-se virando em favor das brancas, e o mestre internacional Diego di
Berardino, que derrotou com pretas ao mestre fide Alvaro Aranha após uma
disputada Grünfeld. Os empates entre o grande mestre André Diamant e o
mestre nacional Yago Labussiere e do grande mestre Yago Santiago e o mestre
internacional Nathan Filgueiras deixa eles a meio ponto dos líderes. Uma
posição onde também aparece, após uma boa recuperação depois de um
começo ruim, o grande mestre Everaldo Matsuura. Nesse grupo de perseguidores
se acha o jovem Stefan Lima, filho do conhecido grande mestre Darcy Lima,
assim como os potiguares Vitor Firmo Rocha e Jordan Barbosa e o cearense Iung
de Pinheiro, todos eles destaques desta edição. Principais duelos da oitava
rodada: Di Berardino - Supi; Do Valle Cardoso - Fier; Quintiliano - Diamant.
Vários candidatos, final aberto!!} 1. e4 {Aproximadamente um terço das
partidas do mestre internacional mineiro come- çam com este lance, embora na
maioria ele confie a sorte da partida na opção 1.d4. A escolha pode estar
relacionada ao fato de Supi defender quase exclusi- vamente com Siciliana,
pelo qual a que segue -jogada pelo condutor das pretas em raras oportunidades-
pode ter sido uma surpresa.} e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O d6 {
Esta é uma ordem frequentemente subestimada pela teoria, levando a uma forma
da variante Steinitz diferida onde as brancas já definiram a posição do seu
rei e as pretas a do cavalo rei. O campeão mundial Emanuel Lasker esteve
entre seus primeiros praticantes. Na atualidade, grandes nomes como Rap- port,
Esipenko ou Sjugirov defendem a causa preta nesta linha. Curiosamente, nesta
mesma rodada foi também a escolha do GM Everaldo Matsuura. [#]} 6. d4 $5 (6.

-522,-29994,-29995] A primeira hora da oitava rodada antecipava uma grande
luta, a julgar pelo que podia se ver nos tabuleiros. É possível perceber o
compromisso dos mestres que aspiram a obter o primeiro lugar na prova mais
importante do xadrez brasileiro em cada lance, cada decisão, que a medida que
se acercam as rodadas finais ganham em profundidade e força. Foi uma rodada
de partidas espetaculares. Na mesa 1 o grande mestre Luis Supi venceu levando
as pretas ao mestre internacional Diego di Berardino, utilizando um
interessante e agressivo esquema contra a variante das trocas. O jogo teve
avanços laterais, roques grandes por ambos os lados, drama, aventuras e um
final de material pesado onde as pretas levaram a melhor parte. É o nosso
jogo do dia. Na mesa 2 o grande mestre Alexandr Fier não logrou quebrar a
formação Reti proposta pelo mestre fide Lucas do Valle Cardoso e teve que se
conformar com uma repetição de lances e o conseguinte empate que baixa os
dois da liderança. Na mesa 3 o grande mestre Renato Quintiliano venceu ao seu
colega André Diamant em um cenário típico de peão isolado proveniente de
uma Nimzoindia. Em uma posição apenas melhor para o primeiro lado André
cometeu um grave erro [19...Be7] que permitiu a Renato a realização de um d5
mortal que abriu as linhas para suas peças, culminando com um ataque
imparável, incluindo uma entrega de torre para destruir a cobertura do rei
preto. Uma definição exata e muito boa -modelo de ataque para este tipo de
posições com peão isolado- do representante de Osasco. Assim, Quintiliano e
Supi compartilham merecidamente a primeira colocação da prova, a falta de
três rodadas. Entre os enxadristas que se posicionam na terceira colocação,
há que destacar ao cearense Iung de Pinheiro, que venceu levando as peças
pretas ao representante de Goias, Yago Labussiere. Iung é até aqui a maior
surpresa da prova. Os principais encontros da rodada nove: Supi - Quintiliano;
De Pinheiro - Do Valle Cardoso; Fier - Mekhitarian.} 1. d4 d5 2. c4 e6 3. Nc3
Nf6 4. cxd5 exd5 5. Bg5 Bb4 {[#] Uma surpresa. Pelo geral, a teoria não
recomenda levar o bispo a b4 quando as brancas podem continuar desenvolvendo
seu cavalo em e2, porém Supi tem uma ideia diferente, vinculando a posição
a temas que são típicas da variante Ragozin} 6. e3 {[#] A continuação mais
usual. As brancas podem também transpor à Ragozin com 6.Cf3, porém o texto
é a recomendação teórica, esperando demonstrar que se as pretas continuam
com os lances típicos do esquema preto na variante das trocas -exemplo ...c6,
0–0– o bispo em b4 pode ficar fora de jogo. Porém as pretas têm outra
forma de tratar a posição: mais arriscada, porém muito interessante} h6 7.

-174,-274,-264,-278,-274,-275,-275,-271,-264,-469,-468] O enfrentamento entre
os dois líderes não decepcionou, se produzindo uma grande batalha no
território da variante 6.Be2, escolhida pelo grande mestre Luis Supi para
enfrentar a Siciliana Najdorf de seu colega Renato Quintiliano. As brancas
jogaram um rápido Cd5, e depois de uma troca nesse ponto a recaptura com
peão provocou uma luta entre as maiorias de peões de cada lado. Parecia que
Supi chegava primeiro na carreira das iniciativas, porém Quinti obteve
contrajogo avançando seus peões na ala de rei. A posição foi derivando em
um final equilibrado porém muito complexo, com as brancas tendo um peão
livre afastado e a vantagem de possuir bispo contra cavalo. Mas também dama
e torre por lado, e as das pretas pareciam algo mais ativas, complementando
uma agressiva maioria de peões avançados na ala de rei. O empate foi um
resultado justo. Com esse resultado, a vitória do mestre fide Lucas do Valle
Cardoso sobre seu colega Iung Pinheiro levando as peças pretas em uma Índia
de Dama -o nosso jogo do dia- lhe permitiu se adicionar aos líderes. Na mesa
3 se registrou outra batalha em um dos clássicos do xadrez brasileiro entre
os grandes mestres Alexandr Fier e Krikor Mekhitarian. A partida se registrou
na variante de Rubinstein na Nimzoindia, e teve um desenvolvimento parelho,
onde as ações derivaram em um final com torre e bispos de diferente cor por
lado. Fier obteve alguma iniciativa e um peão a mais. No tenso apuro de tempo
que siguiu, algumas imprecisões foram trocadas -talvez as brancas tiveram em
algum momento chances reais de vitória-, o peão foi avançando e finalmente
se trocou pelo bispo de Krikor. Restou um final puro de torre e bispo contra
torre, que se estendeu por mais de cento e quarenta lances até se declarar
empate. A rodada entregou algumas surpresas, como os empates do cm Luigy Lira
de Sequeira ante o mestre internacional Diego di Berardino, a vitória do mn
Lucas Tomiello contra o grande mestre Yago Santiago e o empate do mn Stefan
Lima ante o grande mestre Everaldo Matsuura. Outro grande mestre, Darcy Lima,
não deu lugar a surpresas e venceu de pretas ao mn Marcio Jordao Barbosa,
recuperando posições na reta final da prova. A rodada 10 -penúltima da
prova- terá os seguintes enfrentamentos nas primeiras mesas: 1) Renato
Quintiliano - Lucas Do Valle Cardoso; 2) Darcy Lima - Luis Supi; 3) Lucas
Tomiello - Alexandr Fier. Temos três líderes -Quintiliano, Supi e Do Valle
Cardoso- e outros três mestres a meio ponto -Fier, Lima e Tomiello-. (MI Luis

-95,-97,-84,-76,-89,-71,-218,-201,-272,-285,-334,-289] Uma rodada muito tensa
nas primeiras mesas, de ações dramáticas. Dos três mestres que começaram
o dia na liderança, apenas um deles logrou dar um passo na frente. E que
passo! Faltando apenas uma rodada, o meio ponto de luz que saca o grande
mestre Luis Supi depois da sua vitória levando as peças pretas ante seu
colega Darcy Lima -que tinha protagonizado uma grande recuperação após um
começo ruim- bem pode ser decisivo para a sorte da prova. No entanto, ainda
deve enfrentar com muita responsabilidade essa última partida: alguns dos
seus perseguidores podem ter um melhor sistema de desempate. A partida entre
Darcy e Luis é o nosso jogo do dia. Na mesa 1 dividiram o ponto o grande
mestre Renato Quintiliano e o mestre fide Lucas do Valle Cardoso, depois de
uma partida desenvolvida na variante Ragozin do Gambito da Dama, onde nenhum
dos protagonistas pode obter vantagem. E na mesa 3 o grande mestre Alexandr
Fier chegou a obter alguma vantagem no seu jogo ante o mestre nacional Lucas
Tomiello, porém depois de dramáticas instancias e um final muito
interessante o empate o deixa a um ponto do líder, uma diferença que parece
difícil de reverter. Em outros resultados os grandes mestres Krikor
Mekhitarian, Everaldo Matsuura e os mestres internacionais Diego di Berardino,
Roberto Molina e Nathan Filgueiras confirmaram seu favoritismo no rating e
venceram, respetivamente, ao mestre nacional Stefan Lima, aos mestres fide
Alvaro Aranha e Iung Pinheiro e aos candidatos a mestre Mathias Casalaspro e
Luigy de Siqueira. A última rodada tem nas primeiras mesas os enfrentamentos
que seguem: 1) Do Valle Cardoso - Supi; 2) Di Berardino - Quintiliano; 3)
Tomiello - Mekhitarian; 4) Fier - Filgueiras; 5) Molina - Matsuura. Supi leva
8,5 pontos; Do Valle e Quintiliano 8, e o resto dos mencionados 7,5 pontos.} 1.

posição teórica da Siciliana Najdorf entre o mestre fide Lucas do Valle
Cardoso e o GM Luis Supi, quem assegurou assim ao menos compartilhar a
primeira colocação. Nessa hora, esse resultado permitia a um único
competidor o alcançá-lo: o GM Renato Quintiliano, que levando as peças
pretas enfrenta ao mestre internacional Diego di Berardino. O jogo se
desenvolve em uma aguda linha da variante Semieslava. Ademais do título de
campeão nacional, três passagens para a próxima olimpíada estão em jogo,
e muitos mestres ainda tem chances, pelo qual nas mesas seguintes se registra
uma luta sem quartel.Passadas duas horas e meia de jogo, a mesa 2 do duelo Di
Berardino - Quintiliano mostra uma posição vantajosa para o primeiro; as
partidas Tomiello - Mekhitarian e Fier - Filgueiras continuam mostrando
posições equilibradas, embora em posições de diferente caráter: uma aguda
linha da Siciliana Clássica e uma tranquila variante das trocas do Gambito da
Dama. Logo a posição melhor de Di Berardino se transformou em vitória, lhe
permitindo compartilhar a segunda colocação. O resultado também assegura o
primeiro lugar isolado na prova ao grande mestre Luis Supi. Na mesa 4 também
há novidades, com Fier obtendo uma vantagem decisiva. Na mesa 3 Krikor está
tal vez algo melhor, porém com menos tempo no relógio. Pouco depois Fier
vencia, alcançando também a segunda colocação compartilhada. E o jogo
entre Tomiello e Mekhitarian se transformava em uma posição de vantagem
decisiva para o segundo, um final técnico de torre, cavalo e cinco peões
para seu lado contra duas torres e dois peões das brancas. É o nosso jogo do
dia. Com esta vitória, Krikor também compartilha o segundo lugar, e a
definição da equipe olímpica depende agora dos desempates. Boas vitórias
dos grandes mestres Everaldo Matsuura, Darcy Lima e Yago Santiago, finalizando
um torneio que não começou da melhor forma para eles com uma nota positiva.
As posições finais: 1. Luis Supi, 9 pontos; 2-6. Alexandr Fier, Krikor
Mekhitarian, Lucas do Valle Cardoso, Diego di Berardino e Everaldo Matsuura, 8,
5 pontos; 7- 10. Renato Quintiliano, Yago Santiago, Charles Gauche e Darcy
