[Event "Leningrad"] [Site "?"] [Round "0"] [White "Botvinnik"] [Black "Savitsky"] [Result "1-0"] [ECO "E22"] [Opening "Nimzo-Indian: Spielmann, 4...c5"] 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Qb3 {This is an uncommon line against the Nimzoindian, though it does appear from time to time.} 4... c5 5. dxc5 Nc6 6. Bg5 h6 7. Bh4 Nd4 { There is a trick here. What happens if White captures the bishop?} 8. Qa4 Bxc3+ 9. bxc3 {Tripled pawns are usually weak, but since White has an extra pawn, it is OK. Of more concern is the fact that none of the kingside pieces are developed and White has not castled. In fact, he won't do so until the penultimate move!} 9... Nf5 10. Bxf6 Qxf6 11. Rc1 Qg5 {Attacking the rook at c1. But Black should have played more solidly. 11...Qe7 12.Qa5 d6} 12. Qa3 b6 13. Nf3 Qe7 14. g4 {Now the knight has no choice.} 14... Nh4 15. Nxh4 Qxh4 16. Bg2 {The power of a bishop on an open diagonal is impressive. Now the game is won, since Black will lose more pawns without compensation.} 16... Rb8 17. Qxa7 Qg5 18. O-O {18.Qxb8 Qxc1++ would have been embarrassing for White!} 18... Qe5 19. cxb6 {Black has no defense against the advancing pawns, and so he resigned. } 1-0
