[Event "World Championship"] [Site "?"] [Round "0"] [White "Smyslov"] [Black "Reshevsky"] [Result "1-0"] [ECO "C70"] [Opening "Spanish: 4.Ba4"] 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 d6 5. c3 Nge7 6. d4 Bd7 7. Bb3 h6 8. Nbd2 Ng6 9. Nc4 Be7 10. O-O O-O 11. Ne3 Bf6 {Both sides have developed comfortably and Black is putting pressure on the center. White deals with that matter quickly and decisively.} 12. Nd5 Re8 13. dxe5 Bxe5 {13...dxe5 14. Nxf6+ wins material. 13...Ngxe5 14.Nxe5 Nxe5 15.f4 Nc6 16.e5! gives Black a lot to worry about. For example: 16...dxe5 17.Nxf6+ gxf6 18.fxe5 fxe5 19.Bxh6} 14. Nxe5 dxe5 {Not only has White secured the bishop pair, but he has reduced the Black knights to passive functions while his own steed occupies a magnificent post at d5. The d-file is where the action is, so White transfers a rook there.} 15. Qf3 Be6 16. Rd1 Bxd5 {Black's play has been pretty much forced, but now White has both the central file and kingside pressure.} 17. Rxd5 Qe7 {The d7-square would be a nice home for the rook, and White uses the threat of infiltration to secure a more active position for his queen.} 18. Qf5 Nf8 {18...Rad8 looks logical, but White can obtain an advantage by exploiting the indirect pin at f7: 19.Bxh6! gxh6 20.Rxd8 Rxd8 21. Qxg6+ Kf8 22.Qxh6+ Ke8 23.Bd5} 19. Be3 Ne6 20. Rad1 Red8 {White's positio n is very strong, and now he makes a quiet move which deprives Black of the use of f4, and puts him in near zugzwang.} 21. g3 Rd6 {A commital move which leaves Black with a backward pawn, but there was little else available. If the backward pawn were the only drawback, it wouldn't be too bad, but the resulting weakness at b6 will turn out to be important.} 22. Rxd6 cxd6 23. Qg4 {The cheap trick at h6 is not the real point of the move, which has the far more subtle goal of enabling the queen to get to the h4-d8 diagonal. Already Smyslov sees the potential power of a bishop at b6!} 23... Kh8 24. Bb6 Nb8 {Black also appreciates White's last move and hastens to drive the offending cleric from its new post. Reshevsky would no doubt have preferred to play Rc8 first, but that was not possible. 24...Rc8 25. Rd2 Nb8 26.Qd1! Rc6 27. Ba7 Nd7 28.Bd5! Rc7 29.Bxe6 fxe6 30.Rxd6} 25. Bxe6 fxe6 26. Qh4 {Taking advanta ge of the fact that Black cannot exchange at d4 without dropping the d-pawn. But as it turns out White forces the exchange at d8, and still gets his prize.} 26... Qd7 27. Qd8+ Qxd8 28. Bxd8 Nd7 { 28...Nc6 29.Bb6 and Black cannot defend d6.} 29. Bc7 Nc5 30. Rxd6 Rc8 { 30...Nxe4 31.Rxe6 and the e-pawn falls.} 31. Bb6 Na4 32. Rxe6 Nxb2 33. Rxe5 Nc4 34. Re6 Nxb6 35. Rxb6 Rxc3 36. Rxb7 { and the endgame is relatively straightforward.} 36... Rc2 37. h4 Rxa2 38. Kg2 a5 39. h5 a4 40. Ra7 {The rook is properly behind the pawn and also controls the seventh rank, so the kingside pawns can advance easily.} 40... Kg8 41. g4 a3 42. Kg3 Re2 43. Kf3 Ra2 44. Ke3 Kf8 45. f3 Ra1 46. Kf4 a2 47. e5 {An importa nt move, becuase it secures the f6-square, so that when Black trades the a-pawn for the f-pawn, White will be able to place his king at g6.} 47... Kg8 48. Kf5 Rf1 49. Rxa2 Rxf3+ 50. Kg6 Kf8 51. Ra8+ Ke7 52. Ra7+ 1-0
