[Event "Moscow Olympiad"] [Site "?"] [Round "0"] [White "Botvinnik"] [Black "Padevsky"] [Result "1-0"] [ECO "E60"] [Opening "King's Indian: 3.g3"] 1. d4 Nf6 2. c4 g6 3. g3 Bg7 4. Bg2 O-O 5. Nc3 d6 6. Nf3 c5 7. d5 Na6 { This move is not as strange as it looks. In positions with this sort of pawn structure, the knight serves well at c7, where it can support the advance of the b-pawn to b5.} 8. O-O Nc7 9. Nd2 Rb8 10. Qc2 e5 {Why does Black change plans? He should have simply continued with his original idea. 10...b5 11.cxb5 Nxb5 12.Nxb5 Rxb5} 11. dxe6 Bxe6 12. b3 d5 13. cxd5 Nfxd5 14. Bb2 {The theme of this game is now set. Whoever makes best use of the a1-h8 diagonal will win.} 14... b6 15. Nxd5 Bxd5 16. Bxg7 Kxg7 17. Rad1 {White will ccupy the long diagonal a1-h8 with the queen, but only at the most appropriate moment. There is no rush. Right now there is more interesting action on the d-file.} 17... Bxg2 18. Kxg2 Qe7 19. Ne4 { This is an important move, since it covers the critical f6-square.} 19... Rbd8 20. h4 {Better was 20...f6.} 20... Rxd1 21. Rxd1 Rd8 {Black is expecting to exchange pieces and draw. But f6 is weaker than it seems .} 22. Qb2+ {Now!} 22... f6 {The f6-square is pinned. Note that the word "square" is used, rather than "pawn". That is your hint. Can you find the win?} 23. Nxf6 Kf7 { 23...Qxf6 24.Qxf6+ Kxf6 25.Rxd8 or 23...Rxd1 24.Nd5+ or 23...Rd4 24.e3} 24. Rxd8 Qxd8 25. Nxh7 Ne6 26. Qe5 b5 27. Ng5+ {White has two extra pawns, and that is enough to win the queen and pawn endgame.} 27... Nxg5 28. hxg5 Qa8+ 29. e4 Qc6 30. Kf3 c4 31. bxc4 Qxc4 { This makes it easy by allowing White to exchange queens.} 32. Qd5+ {Black resig ned. If you think that you can save the position, go ahead and play it out with Gambit as your antagonist!} 1-0
