[Event "match-tournament"] [Site "Ch World , Hague/Moscow (Neth"] [Round "0"] [White "Botvinnik"] [Black "Smyslov"] [Result "1/2-1/2"] [ECO "D90"] [Opening "Gruenfeld: Three Knights Variation"] 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. Nf3 Bg7 5. Qb3 dxc4 6. Qxc4 O-O 7. e4 Bg4 8. Be3 Nfd7 9. Nd2 Nb6 10. Qd3 c6 11. f3 Be6 {A comparison with the previous position favours Black in some respects; the Bg7 is very well placed striking directly through the centre d4-e5 square. However, there are more minor pieces on the board, therefore White's space advantage has more significance here.} 12. Rd1 Na6 {Black's primary strategical task here is to fix white's vulnerable d-pawn so her concentrates his forces on the d5 square} 13. a3 Qd7 14. Qc2 Nc7 (14... Bxd4 15. Ndb1 c5 16. Nb5 Rac8 17. Bxd4 cxd4 18. N1c3 { White wins a pawn, which, however, will give him only a slight advantage}) 15. Nb3 Bc4 (15... -- 16. Nc5 {securing two Bishops}) 16. Be2 Bxe2 17. Qxe2 Rad8 18. O-O Qe6 19. Nc5 Qc8 20. Kh1 Nd7 21. Nb3 b6 {The attack on the d-pawn has fizzled out, so Black must think of some other way to keep his opponent busy} ( 21... e5 22. d5 $14) 22. Qc4 Qb7 23. f4 e6 24. Rc1 Nf6 25. Bg1 Rc8 26. Rc2 Rfd8 27. Qe2 Nb5 {Suddenly the game flares up. For that matter, any further waiting tactics by Black would be questionable in view of the vulberability of his c-pawn} 28. e5 (28. Nxb5 cxb5 29. Rxc8 Rxc8 30. e5 Nd5 31. Qxb5 Rc2 $44) 28... Nxc3 29. bxc3 Nd5 30. c4 (30. Nd2 { More accurate, now Black will be able to save himself because of the d4weakness }) 30... Ne7 31. Nd2 Nf5 32. Ne4 Nxd4 { Black gives up the exchange, thereby smashing White's centre} 33. Bxd4 Rxd4 34. Nd6 Rxd6 35. exd6 {This pawn must soon fall, so that Black, with two pawns for the exchange, will have full compensation, at least as regard material. The task which he faces in the endgame, however, is far from simple, mainly because his extra pawns can't play any active part} 35... c5 36. Rd2 Rd8 37. Qf3 Qxf3 38. Rxf3 Bd4 39. g3 Rxd6 40.
