Bd3 Nbd7 6. f4 dxc4 7. Bxc4 b5 8. Bd3 Bb7 9. Nf3 a6 10. a4 {The obvious move would have been to castle here.} 10... b4 11. Ne2 c5 12. O-O Be7 13. a5 {White is driving on the wrong side of the road! He should be acting on the kingside.} 13... O-O 14. Ng3 g6 { A good defensive move, which keeps the f-pawn from advancing.} 15. Qe2 cxd4 16. exd4 Nb8 17. Ne5 {This is a pawn sacrifice, but it is well-motivated because Black has not completed his development yet.} 17... Nc6 { Bogoljubow declines, appreciating the value of development.} 18. Nxc6 Bxc6 19. Bc4 {Alekhine later admitted that he should have just grabbed the pawn at a6.} 19... Bb7 20. Be3 {Here Black could have obtained an excellent position by establishing a blockade at d5 with 20...Nd5. Instead, he regroups.} 20... Qd6 21. Rad1 Rfe8 22. b3 Bf8 23. Rd3 {An ugly move, breaking off the communication on the a6-f1 diagonal. But Alekhine, recognizing his difficult position, starts swimming. That is, he makes seemingly aimless moves to confuse the opponent.} 23... Qc7 {Black should have attacked down the h-file with 23...h5!, but the ugly rook at d3 may get to the g-file or h-file, so he refrains. White continues to tread water.} 24. Qa2 Bd6 25. Bd2 Qc6 26. Be1 Rad8 27. Rd2 { White's position has become very artificial, and the Be1 and Qa2lookparticular ly misplaced. But the awkwardness of his moves is confusing Bogoljubow.} 27... Be7 {This was a major error. Black should be attacking on the kingside, and so the bishop should have moved to b8, keeping pressure on the long diagonal, and moving to the a7-g1 diagonal when needed there.} 28. Qb2 Rd7 29. Rc2 { White's "swimming" maneuvers have paid off, though he is not out of the water yet. Still, his pieces are much better coordinated here.} 29... Qd6 { Black could have kept the advantage with 29...Ng4!} 30. Ne2 Nd5 {Much too late. Bogoljubow should have tried to get back to the previous note by playing 30... Qc6 31.Ng3Ng4!} 31. Qc1 {White occupies the important c-file. The swimming is over and Alekhine now plays with purpose. Finally he will be able to set his sights on the kingside.} 31... Bd8 32. Bg3 {Threatening f4-f5.} 32... Qe7 33. Ra2 Qf6 34. Qd2 Qf5 {Black has blockaded the f-pawn, but the queen is too heavy a piece for this purpose. Now the players drift into time-trouble for a while.} 35. Bd3 Qf6 36. Bc4 Be7 37. Qd3 Red8 38. Be1 Qf5 39. Qd2 Qe4 40. Bd3 Qe3+ 41. Bf2 {This was the sealed move. The game was adjourned at this point, and Alekhine had some time to work out his strategy.} 41... Qxd2 42. Rxd2 Rc8 43. Bc4 {A good move. The idea is to cut off the c-file so that the rooks can be repositioned onto it.} 43... Kg7 44. g3 Rcd8 45. Rc1 h6 46. Bd3 f5 47. Rdc2 {White now has control of the only open file.} 47... g5 {A terrible move, but it is hard to blame Bogoljubow, who just didn't see the brilliant reply.} 48. g4 {A strong move which opens up the kingside and makes the previously useless bishop at d3 into a fighting weapon on the b1-h7 diagonal.} 48... Nxf4 { 48...gxf4 49.gxf5 exf5 50.Bxf5} 49. Nxf4 gxf4 50. gxf5 e5 { 50...exf5 51.Bxf5 Rd5 52.Rc7} 51. Re1 { A final brilliant move, preparing a finishing combination.} 51... exd4 { Now White controls both open files and can force a simplification which leads to a winning position.} 52. Rxe7+ Rxe7 53. Bh4 Kf7 54. Bxe7 Kxe7 55. Rc7+ Rd7 { Black has no choice, but now the f-pawn advances.} 56. f6+ Ke8 57. Bg6+ Kd8 58. f7 Kxc7 59. f8=Q f3 60. Qxb4 Rd6 61. Bd3 1-0
