1. d4 f5 { The Dutch Defense. Black controls the central square e4 with a flank pawn. } 2. g3 e6 3. Bg2 Nf6 { You can easily see that Tartakower controls most of the center. } 4. c4 { Bogoljubow grabs a portion of the center for himself. } 4... d5 { This move creates "tension" in the center. The White c-pawn and the Black d-pawn are both poised for a capture. The center can now open up at any time, when one player decides it's advantageous to do so. } 5. Nf3 c6 6. O-O Bd6 { Tartakower now influences three of the four central squares. } 7. Nc3 { Bogo exerts influence on all four central squares. } 7... Nbd7 8. Qc2 { Nearly every move by both players so far has been part of a fight for the center. } 8... O-O 9. cxd5 { The tension in the center breaks as Bogo decides to trade pawns. } 9... cxd5 10. Nb5 { Attacking the hanging Bishop. } 10... Bb8 11. Bf4 Bxf4 12. gxf4 { Although the f-pawns are doubled, this actually increases White's central grip. Two pawns now control e5 and the d7-Knight doesn't have much of a future. } 12... Nb6 { Tartakower decides to improve the weak position of his Knight. } 13. Nc7 { This starts a round of threats and defenses. } 13... Rb8 14. Ng5 Qd6 15. Qc5 Rd8 16. Qxd6 { Bogo decides the time is ripe to swap off the Queens. } 16... Rxd6 17. Nb5 Rd8 18. a4 ( 18. Nxa7 Bd7 { While it's true that White has won a pawn, the Black Bishop cuts off the Knight's escape squares. Every square the Knight can move to is covered by the Bishop. } ) 18... h6 19. Nf3 Bd7 20. Ne5 a6 21. Nc3 Rdc8 22. Rfc1 { Making sure that Black doesn't get undisputed control of the c-file once the c3-Knight moves away. } 22... Bxa4 23. Nxa4 Rxc1+ 24. Rxc1 Nxa4 25. b3 Nb6 26. Rc7 { The Rook comes to the seventh rank, where it will be strong. Black must now keep the pawns on b7 and g7 guarded, which ties up some of his army. This makes up for the pawn White has sacrificed. } 26... Nc8 27. Nd3 Nd6 28. e3 b6 29. Rc6 { While it's true that the Rook has abandoned the seventh rank, it still attacks the b6-pawn and the d6-Knight. Black must keep the pawn guarded and find a way to defend the threatened Knight. } 29... Nfe8 30. Bf3 { The idea is to capture on e8. Then if ...Rxe8, White replies Rxd6. If ...Nxe8, then Rxe6 and the d5-pawn is isolated. } 30... Kf7 31. Bh5+ Ke7 { The King covers everything. Both the d6-Knight and e6-pawn are now adequately defended. } 32. h4 Nf6 33. Be2 Nd7 34. Ne5 Nxe5 35. fxe5 Nb5 36. Bxb5 axb5 { Now Black's in some trouble. The b-pawns are both doubled and isolated. } 37. Rc7+ Kf8 { Forced, otherwise 38.Rxg7. } 38. b4 { Bogo deftly keeps the b-pawns from advancing. } 38... Ra8 { Tartakower decides to voluntarily give back the pawn in order to get some play for his Rook along the a-file. } 39. Rc6 Kf7 { If Tartakower leaves the e-pawn undefended, White will capture it for sure. This will leave both b-pawns plus the d-pawn isolated -- a recipe for certain disaster! } 40. Rxb6 f4 41. Rb7+ { Bogo plays an in-between move. Instead of automatically recapturing on f4, he checks first to harass the Black King. } 41... Kf8 42. exf4 Ra1+ 43. Kg2 Rd1 44. Rxb5 Rxd4 45. Kg3 h5 46. Rb7 g6 47. b5 ( 47. Rb6 Kf7 ) 47... Rb4 48. b6 Rb3+ 49. f3 { Now here's an interesting situation. Black's Rook is poised to capture the advancing b-pawn. White's Rook is ahead of the pawn, blocking its advance. How can White get the Rook out of the pawn's way? } 49... Rb4 50. Rb8+ Ke7 51. b7 Kd7 52. Rg8 { The fact is that White can't get the Rook out of the pawn's way without losing the pawn. The trick for White is to give up the pawn at the right moment, one at which White can likewise win material. } 52... Rxb7 53. Rg7+ Kc6 54. Rxg6 Kc5 55. Rxe6 d4 { Tartakower's only hope is to be the first to promote a pawn. } 56. f5 Rd7 57. Kf2 Kd5 58. Re8 Ra7 59. f6 Rc7 60. Re7 Rc8 61. f7 ( 61. f7 Rf8 62. e6 Ke5 63. Re8 Kf6 64. Rxf8 Kxe6 { Now White is a Rook up. Guarding the f7-pawn is no longer important. The procedure now would be to wipe out the Black pawns and either promote a surviving White pawn or just mate the Black King with the White King and Rook. } ) 1-0
