1. d4 {ChessBase} Nf6 2. c4 e6 3. Nc3 d5 4. cxd5 Nxd5 $5 {For a player used with the stable structures of the exchange variation, this unexpected capture with the knight can come as a slightly unpleasant psychological surprise. Since in the structure arising after the exchange on c3 White hardly has a better square for the development of his king's knight than f3, play is likely to transpose to the Semi-Tarrasch system.} 5. e4 Nxc3 6. bxc3 c5 7. a3 $5 {White intends to deviate from the course of the game suggested by Black. His last move intends to transpose to some kind of Petrosian variation of the Queen's Indian (4.c3 b7 5.a3 d5 6.cxd5 xd5 7.c2 followed by e4) if Black develops his queen's side with ...b6 and ...b7. In that case, White would be in a better situation, since he would spare the move c2, maintaining the possibility of developing the queen later and to a more favourable square. (In the QI, the queen frequently has to lose a tempo after, say, ...c7 or ...c8). However, Black can make use of the time made available by delaying the development of his bishop and, equally important, of the b6-square and the a5-d8 diagonal. We can see that the game has an independent character compared to the known variations.} (7. Nf3 {would most likely transpose to a genuine Semi-Tarrasch after a further check on b4. It is worth noting that, even though the formal purpose of the move a3 is the same as in the QI, namely to prevent ...b4, the concrete circumstances are slightly different. In the QI, the bishop would pin the c3-knight, increasing Black's influence over the e4-square, while in the QG the check on b4 would just lead to simplifications, which generally suit Black, who has willingly given up the control of the centre.}) ({RR} 7.

Andere Fortsetzungen bereiten dem Nachziehenden wenig Schwierigkeiten.} ({Weiss kann natürlich auch eine Symmetriesituation anstreben, in der er am Zug ist, und} 5. e3 Nc6 6. a3 {spielen. Doch das bietet nicht so gute Aussichten auf Vorteil wie der Tausch auf d5.}) (5. Bg5 cxd4 6. Qxd4 (6. Nxd4 e5 7. Nf3 d4 8. Nd5 Be7) 6... Nc6 7. Bxf6 gxf6 8. Qh4 dxc4 9.

Zur Tarrasch-Verteidigung gelangen wir, wenn Schwarz mit dem Bauern wiedernimmt. Damit willigt er in einen Einzelbauern auf d5 ein und hofft, dass sein Einfluss im Zentrum dafür genügend Gegenchancen bietet. Nach 5...xd5 sprechen wir von der "Halb-Tarrasch- oder Semi-Tarrasch-Verteidigung", weil Schwarz den von Tarrasch geforderten frühen Gegenstoss c7-c5 ausführt, aber dann von der Grundidee abweicht und den Einzelbauern vermeidet. Er nimmt dafür einen klaren Nachteil in Kauf: Schwarz hat deutlich weniger Einfluss in der Mitte als in der Tarrasch-Verteidigung. Schwarz ist nicht nur im Zentrum unterlegen, ihm fehlt dafür auch ein Gegenwert. In letzter Zeit (1995) hat die Halb-Tarrasch-Variante an Beliebtheit im internationalen Schachgeschehen langsam aber sicher eingebüßt. Grossmeister wählen bei der Suche nach einer soliden Methode im Abgelehnten Damengambit lieber die orthodoxen Varianten (ohne 3. oder 4...c5, mit 3...f3 und baldigem ...e7) als die Halb-Tarrasch-Spielweise. Die Orthodoxe Verteidigung gibt Schwarz mehr Kontrolle im Zentrum und bietet nicht geringere Ausgleichs- oder Gewinnchancen als Halb-Tarrasch.} ({Der Vollständigkeit halber erwähne ich, dass} 5... cxd4 {"spielbar", aber mit Vorsicht zu genießen ist.

Bg2 Be7 8. O-O O-O 9. Bg5) 6. e4 {Warum nicht? Schwarz hat dem Gegner erlaubt, kostenlos ein starkes Bauernzentrum aufzubauen, und es gibt keinen theoretischen Grund, warum Weiss diesen Weg nicht einschlagen sollte. Dennoch hat dieser dem Thema am ehesten entsprechende Plan nie den Beliebtheitsgrad erreicht, den er verdient. Dafür gibt es zwei Gründe, einen schachlichen und einen, der den "Spielprozess" betrifft. Zum ersteren ist zu sagen, dass Weiss ausserordentlich genau und kraftvoll agieren muss, wenn er den vereinzelten d-Bauern, der sich bald auf d5 ergeben wird, zu einem Plusfaktor machen will. Offenbar wollen sich viele Spieler nicht gern freiwillig einer solchen Herausfordrung stellen. Die beiden vollgültigen Alternativen, die in der Spielpraxis häufiger vorkommen, sind:} (6. e3 {mit der gebräuchlichen Folge} Nc6 7. Bd3 cxd4 8. exd4 Be7 9. O-O O-O {Damit ist eine typische Stellung mit dem vereinzelten d-Bauer auf der 4.Reihe und allen leichten Figuren noch auf dem Brett. Das erhöht die Elastizität des weissen Spiels und vermindert das Risiko: anders als in der 6.e4-Variante erhält Schwarz keine Bauernmehrheit am Damenflügel. Der zuvor erwähnte Grund, der mit dem "Spielprozess" zusammenhängt, betrifft die Zugreihenfolge. Was die Varianten nach 6.e3 angeht, so ergeben sich 50% der Stellungen aus dem Panow-Angriff gegen die Caro-Kann-Verteidigung (siehe oben Partie Adams-Seirawan). Ausserdem kommt eine beträchtliche Anzahl über die Englische Partie zustande, wenn Schwarz frühzeitig c7-c5 und Weiss e2-e3 gezogen haben (siehe oben Partie Ivanov-Dlugy).}) (6. g3 {wobei die thematische Stellung nach den Zügen} Nc6 ({oder} 6... cxd4 7.

Nxd5 exd5 {oder eine starke Mitte anzustreben, indem er nun doch den Zentrumsvorstoss 9.e4 wagt. Auch diese beiden Pläne sind Spielern von geschlossenen Systemen durchaus geläufig. Die nach 6.g3 angegebene Stellung der Hauptvariante ergibt sich meistens aus einer anderen Zugfolge als der "offiziellen". Tatsächlich werden die Stellungen nach dem 8.Zug und nach 9.xd5 exd5 üblicherweise erreicht, indem Weiss in der Englischen Eröffnung frühzeitig g2-g3 zieht und erst später (d2) d3-d4. Ein charakteristisches Beispiel ist die oben angegebene Partie Sirotanovic-Ruban.}) 6... Nxc3 {Der einzig richtige Zug. Obgleich damit das weisse Zentrum durch Überführung des Bauern b2 nach c3 gestärkt wird, sind die mit dem Tausch verbundenen Pluspunkte wichtiger: Schwarz verliert keine Zeit mit einem Rückzug, und der Abtausch der Leichtfiguren verringert die einengende Wirkung des breiten weissen Bauernzentrums.} 7. bxc3 cxd4 {Wieder mit dem thematischen Ziel, Leichtfiguren zu tauschen, hier die schwarzfeldrigen Läufer.

Bd2 Bxd2+ 10. Qxd2 O-O {[%mdl 32] Die Bauernformation im Zentrum ist geklärt und je zwei Leichtfiguren sind abgetauscht. Was Sie nun sehen ist das, womit beide Seiten fertig werden müssen: der Startpunkt der kritischen, wesentlichen Varianten des Halb-Tarrasch-Komplexes. Betrachten wir die strategischen Themen für beide Seiten. WEISS zielt darauf, den d-Bauern wirkungsvoll vorzurücken, zunächst nach d5. Dort wird er sich im schwarzen Lager befinden und die Rolle eines Freibauern bekleiden und - wie Weiss hofft - ein Ärgernis für Schwarz sein, weil er nur drei Schritte vom Umwandlungsfeld entfernt ist und ausserdem die Verbindung der schwarzen Streitkräfte stört. Hinter dem Rücken des d-Bauern wird Weiss seine Türme auf den zentralen d- und e-Linien aufmarschieren lassen. Er wird versuchen, mit Hilfe seines räumlichen Übergewichts einen Königsangriff einzuleiten. Bei Schwarz fehlen am Königsflügel die leichten Figuren als Helfer bei der Verteidigung, und deshalb sind die weissen Aussichten, erfolgreich durchzudringen, günstig. SCHWARZ hat mit zwei Zielen zu jonglieren: (1) den weissen d-Bauern als harmlos hinzustellen und seinen König in ausreichender Sicherheit zu lassen; (2) seine Bauernmehrheit am Damenflügel voranzubringen und einen verwendbaren Freibauern zu bilden. Voraussichtlich wird dies nur im Endspiel möglich sein. Daher muss Schwarz unbedingt das Mittelspiel unbeschadet überstehen. In einer praktischen Partie ist die Lage für einen erfahrenen Weissspieler die weit angenehmere: eine Ungenauigkeit, die er sich leistet, kann vielleicht bedeuten, dass sein Vorteil sich verflüchtigen wird; ein Schnitzer von Schwarz wird höchstwahrscheinlich seine Stellung ruinieren.} 11.

Aber diese Pläne haben auch negative Seiten. Der erste Plan schwächt den d4-Bauern und befreit teilweise die schwarzen Läufer.
