1. d4 Nf6 2. Nf3 d5 3. c4 e6 { The players have transposed into the Queen's Gambit Declined. A prominent feature of this opening is Black's difficulty in developing the c8-Bishop. } 4. Nc3 c6 5. Bg5 h6 6. Bh4 dxc4 7. e3 { There is absolutely no reason why Janowski couldn't have played 7.e4. } 7... b5 { Now White will have to live for a while with a restricted Queenside. } 8. Be2 Nbd7 9. a4 Qb6 { Tartakower prevents 10.axb5 cxb5 11.Nxb5. } 10. O-O Bb4 11. Qc2 Bb7 12. b3 { Janowski miscalculates. More constructive moves were possible here, such as reinforcing the Queenside with 12.Rfc1. } 12... cxb3 13. Qxb3 Bxc3 14. Qxc3 b4 { Tartakower has a protected passed b-pawn. Its creation was made possible by White's error on move 12. } 15. Qb2 a5 16. Ne5 { Janowski, a pawn down, shouldn't be trading down since the resulting endgame would not give him good chances. } 16... Nxe5 17. dxe5 Nd5 18. Rfc1 Qc7 { Tartakower anticipates what's coming next and gets his Queen off of the b-file. } 19. e4 Nc3 { Imagine for a moment that the Black Queen is still on b6... } 20. Rxc3 { ...Black could not have recaptured on c3 due to Qxb6. This is why Tartakower abandoned that square on move 18. } 20... bxc3 { Janowski sacrifices the exchange to get rid of the pesky Knight. } 21. Qxc3 g5 22. Bg3 O-O-O { For crying out loud! Why does Tartakower castle to a side of the board where he has no real cover for the King??? Castling Kingside would have been infinitely better! } 23. Rb1 c5 24. Rb5 { Janowski now has an attack brewing. His major pieces go gunning for the Black a-pawn. } 24... Kb8 25. f3 { Janowski can't go pawn hunting yet (see the variations). He creates a flight square for his King in case of a Black counterattack along the open file. } ( 25. Qxa5 Qxa5 26. Rxa5 Rd2 { Black counterattacks along the open file. } ) ( 25. Qxc5 Qxc5 26. Rxc5 Rc8 27. Rxc8+ Rxc8 { Black, ahead the exchange, will win the endgame. } ) 25... Rd4 26. Rxc5 ( 26. Rxa5 Rhd8 27. Rxc5 Qd7 ) 26... Qd7 27. Bf2 Rxa4 28. Rxa5 Rxa5 29. Qxa5 { Scary stuff for Black! His King stands uncovered on the Queenside and White's Bishops aim in its direction along the open diagonals. } 29... Qc7 { Tartakower's idea is that a best defense is a good offense. When in doubt, complicate the game! } 30. Bb6 { The threat is mate in four. } 30... Qc1+ 31. Kf2 { Now you see the reason for the move 25.f3. } 31... Kc8 32. Bc5 g4 33. Bd6 gxf3 34. Qa7 { Here's another threat of mate in four. But, even more important, Janowski is on the horns of a dilemma. He really needs the e2-Bishop to join in the attack on the Black King, but moving the Bishop will allow Black a dangerous counterattack. What can he do? } ( 34. Bb5 fxg2 35. Kxg2 Rg8+ 36. Kf3 Qh1+ 37. Kf2 Qg2+ 38. Ke1 Qxe4+ 39. Be2 Rg1+ 40. Kd2 Qd4+ 41. Kc2 Be4+ 42. Bd3 Qxd3+ 43. Kb2 Rb1+ 44. Ka2 Qb3# ) 34... fxe2 ( 34... Bxe4 $4 { This would just take away the Black King's last remaining cover and further aid White. } 35. Ba6+ Bb7 36. Qxb7+ Kd8 37. Qe7# ) 35. Qb8+ { The best Janowski can do here is chase the Black King around and hope for a mistake by his opponent. } 35... Kd7 36. Qxb7+ Kd8 37. Qb8+ Kd7 38. Qa7+ Kd8 39. Qa5+ Kc8 40. Qa6+ Kd7 41.
