[Event "Bath"] [Site "?"] [Round "0"] [White "Hug"] [Black "Spassky"] [Result "0-1"] [ECO "A07"] [Opening "Reti: KIA"] 1. Nf3 d5 2. g3 c6 3. Bg2 Bf5 4. O-O Nf6 5. d3 e6 6. Nbd2 Be7 7. Qe1 { Against Hug's King's Indian Attack, Spassky has selected a solid defensive formation.} 7... h6 8. e4 Bh7 9. Qe2 O-O 10. b3 {White turns his attention to the queenside. The more direct 10.e5 might have been more effective.} 10... a5 11. a3 c5 12. a4 Nc6 {Black's position looks much more natural.} 13. Bb2 Re8 14. Ne5 {White's strategy involves using the a1-h8 diagonal, and, in particular, the e5-square. Spassky cuts across this plan with the next move.} 14... Nd4 15. Qd1 {15.Bxd4 cxd4 The c-file will be used by Black to put tremendous pressure on the backward pawn at c2.} 15... Qc7 16. Nef3 dxe4 17. dxe4 Red8 {This is an example of what I call man-on-man coverage, similar to the basketball notion that one piece sometimes plays the role of dealing with a particular enemy piece. The rook confronts the enemy queen from a distance.} 18. Re1 Nxf3+ 19. Bxf3 {Forced, because of the pin on the knight at d2.} 19... c4 {Threatening a fork at c3.} 20. bxc4 Bb4 {More pressure is added to the pin. } 21. c3 Be7 22. Qe2 Nd7 {The next battleground is the c5-square.} 23. Nb3 Ne5 24. c5 Bxc5 25. Nxc5 {We have reached the critical position. Now Spassky uses a deflection which, in combination with a fork, leads to a winning position. Do you see how? If not, set this game up against Gambit.} 25... Rd2 26. Nd3 { 26.Qxd2 Nxf3+ 26.Qe3 Nc4 The queen and bishop at b2 are forked.} 26... Rxe2 27. Bxe2 Nc4 28. Bf1 Qc6 29. Bc1 Bxe4 30. Nc5 Bd5 0-1
