[Event "Soviet Championship"] [Site "?"] [Round "0"] [White "Botvinnik"] [Black "Koblents"] [Result "1-0"] [ECO "D30"] [Opening "QGD: 3.Nf3 Nf6"] 1. d4 d5 2. c4 e6 3. Nf3 Nf6 4. Nc3 c6 5. e3 Nbd7 6. Bd3 Be7 7. O-O O-O 8. b3 b6 9. Bb2 Bb7 10. Qe2 Rc8 11. Rac1 Bd6 {Both sides have developed in accordance with the principles of the opening. Now White takes action to secure more territory in the center.} 12. e4 dxc4 13. bxc4 e5 { Black is not about to permit his opponent to control the entire center!} 14. dxe5 Bxe5 15. Rcd1 Qe7 16. Nh4 {White now turns his attention to the kingside. Black should reply with a sensible move like 16...Rfd8. Instead, he makes a reckless move on the queenside.} 16... Qb4 17. Qc2 {Black's king seems safe, but if the bishop is dislodged from e5, then the e-pawn will advance an open up a diagonal for the battery of queen and bishop.} 17... Nc5 18. a3 Qa5 19. Nf5 Rcd8 20. f4 Nxd3 21. Rxd3 {White does not mind this exchange, since the rook can operate on the kingside. Black can win a pawn here, and does.} 21... Qc5+ 22. Kh1 Qxc4 {The bishop at e5 is under attack, but so is the rook at d3. Black probably anticipated a series of exchanges on the third rank, but Botvinnik has a better idea.} 23. fxe5 Rxd3 24. exf6 { The attack is more important than a small amount of material.} 24... Rd7 { 24...Rxc3 25.Ne7+ Kh8 26.fxg7+ Kxg7 27.Bxc3+ f6 28.Bxf6+ Kh6 29.Qd2+ Kh5 30. Qg5+} 25. Qc1 Rfd8 {Now White would like to play Qg5, but there is a small problem -- the rook at f1 is en prise.} 26. Rg1 {Black resigned, because there was no hope of a successful defense. Try playing the Black side against Gambit and you will see why.} 1-0
