[Event "Biel Interzonal"] [Site "?"] [Round "0"] [White "Huebner"] [Black "Tal"] [Result "0-1"] [ECO "A17"] [Opening "English: Nimzo-English, 4.Qc2"] 1. c4 Nf6 2. Nc3 e6 3. Nf3 Bb4 { This is an aggressive line which appealed to Tal's attacking instincts.} 4. Qc2 c5 {With the queen gone from the d-file, Black puts pressure on d4.} 5. g3 Nc6 6. Bg2 O-O 7. O-O Qe7 8. d3 h6 { Black can afford such luxuries thanks to his advanced development.} 9. e4 d6 { White now tries to mobilize a kingside attack before Black can blast open the queenside.} 10. Nh4 Rb8 11. f4 Bd7 12. h3 Nd4 { This square is unguarded because the knight has moved from f3 to h4.} 13. Qf2 b5 14. Be3 bxc4 15. dxc4 Bc6 16. Rae1 Qb7 17. Bc1 Qa6 { Black has plenty of queenside counterplay.} 18. e5 dxe5 19. fxe5 Nh7 { This knight will find an effective home at g5.} 20. Bxc6 Qxc6 21. Re3 Ng5 22. Qg2 Qa6 23. b3 {The stage is set for a deflection sacrifice. Tal has a vision of a knight check at e2. That seems impossible, given that the square is covered by a rook, knight and queen. But of such dreams, combinations are made!} 23... Nxh3+ 24. Qxh3 Bxc3 25. Qg4 {25.Rxc3 Ne2+ 26.Kh2 Nxc3} 25... Qxa2 26. Rxc3 {Now Black could regain material with the fork at e2, but instead Tal uses yet another deflection, this time to take the pressure off the g-file.} 26... h5 27. Qxh5 Ne2+ 28. Kh1 Nxc3 29. Bh6 {This has no sting now.} 29... Qe2 {An offer to exchange queens which White cannot afford to accept.} 30. Qg5 Qe4+ {This check provides a road home for the queen.} 31. Rf3 Qh7 { Now everything is defended, and the remainder of the game is easy.} 32. Bxg7 Qxg7 33. Qxg7+ Kxg7 34. Rxc3 Rfd8 {Rooks belong on open files!} 35. Nf3 Rd1+ 36. Kg2 Rbd8 37. Rc2 R8d3 38.
