1. Nf3 d5 2. c4 { As we've come to expect, Tartakower plays in the hypermodern style, controlling the center from the flanks instead of occupying it with pawns. } 2... d4 { This odd-looking move serves a number of purposes: it prevents d2-d4, inhibits e2-e4 (because of ...dxe3 e.p.), and prevents Nc3. } 3. b4 { Tartakower decides to give the center to his opponent. White will now expand on the Queenside. } ( 3. g3 { This has also been played successfully. The idea is to fianchetto the Kingside Bishop and control the center from afar. } ) 3... a5 { You would think that Janowski would continue with his central strategy. Instead he plays a defensive move to counteract White's Queenside intentions. } 4. b5 c5 5. e3 g6 ( 5... dxe3 6. fxe3 { Black has given up his central pawn majority. } ) 6. exd4 cxd4 7. d3 { White has a Queenside pawn majority, so this is the side from which he should launch his attack. Black has a central pawn majority, so his attack will probably come straight up the middle. } 7... Bg7 8. g3 Nd7 9. Bg2 { The fianchettoed Bishop strikes at the Queenside -- where White will ideally launch his attack. } 9... Nc5 10. Ba3 Qb6 11. O-O Bf5 12. Nh4 Bc8 ( 12... Bxd3 13. Bxc5 Qxc5 14. Qxd3 { Black would be down a piece for a pawn. } ) 13. Qe2 Bf6 14. Nd2 Bxh4 15. gxh4 Ne6 16. Qe5 f6 17. Qg3 { The basic problem here is that Janowski has weakened the pawn structure on both sides of the board, leaving his King nowhere to run. } 17... Nh6 18. Be4 { Note that Tartakower has switched his emphasis from the Queenisde to the Kingside in order to take advantage of the new opportunities there. } 18... Nf5 19. Bxf5 gxf5 { Note that the White Queen and King are on the same open file. This is extremely dangerous. Black could play ...Kf8 followed by ...Rg8 and win the White Queen. } 20. Qf3 { Though there was no immediate danger to the Queen, Tartakower removes it from the open file to prevent any unpleasant surprises from happening later. } 20... Nf8 21. Qh5+ Ng6 22. Rae1 e5 { Janowski is plugging the holes but his King is all alone in the center. This can't be good... } 23. f4 { There are two Black units "controlling" f4 -- but this is just an illusion. Both the e5-pawn and g6-Knight are pinned. } 23... Kd8 { This eliminates both pins, but now White can easily break through. } 24. fxe5 Rg8 { The idea is ...Nf4, checking the King and winning the Queen. } ( 24... fxe5 25. Qg5+ Kc7 26. h5 Rg8 27. Kh1 Bd7 ( 27... h6 28. Qxh6 ) 28. hxg6 Rxg6 29. Qe7 ) 25. Qxh7 Be6 26. Kh1 Nxe5 { Keep your eye on this four-square block. } 27. Qe7+ { Tartakower nicely forks the King and f6-pawn, but the pawn will not fall quite yet. } 27... Kc8 28. Bc5 { Wow! Janowski's in a world of trouble now. It's easy to see the effect that opening up his own Kingside has had. The Black Queen is the only piece defending the e6-Bishop and it has no retreat square from which it can continue to protect it. } 28... Qd8 { Desperation. Janowski would like nothing better than a Queen swap, but that's just not going to happen. } 29. Qxe6+ Kb8 ( 29... Qd7 30. Qxg8+ ) 30. Rxe5 { Tartakower sacrifices a Rook to open lines for his attack. } 30... fxe5 31. Qxe5+ Kc8 32. Qxf5+ ( 32. Qxf5+ Qd7 33. Qxd7+ Kxd7 34. Rf7+ Ke6 35. Rxb7 { White has a huge material advantage and the Black King is caught in the board's center. } ) 1-0
