Nf3 Ne7 { 5..c5 or ..h5 would be my choice here } 6. Bd3?! { Trading pieces when enjoying a space advantage is rarely the best choice } (6. c3! { Solid move, waiting for Black to choose his setup. } 6... c5?! 7. dxc5 $14) 6... Bxd3 7. Qxd3 Nf5! { Correct setup by Black here, in my opinion. } 8. O-O Be7? { I would love to see Black go for 8..c5! here. It's time to challenge White's centre. } (8... c5 9. c3 Nc6 (9... h5!? { Cements the knight on f5 })) 9. b3?! { Preparing c4, but I don't like the plan of pushing pawns on the queenside. White's idea should be to develop then aim for an attack on the king } (9. g4! Nh4 10. Nxh4 Bxh4 11. Be3 Nd7 12. Nd2 $14 { White is ready to push f4-f5 }) 9... O-O?! (9... c5! { Stops White's idea of c4 and gives a square for Nc6 } 10. c3 h5! { To prevent g4, followed by quick development. }) 10. c4 (10. g4! Nh4 11. Nxh4 Bxh4 12. g5! { Catches the bishop out on h4. White is better. }) 10... Nd7 11. c5?! { A natural follow up to c2-c4, but this was the wrong plan for the position. } 11... b6 12. b4 (12. cxb6 c5!! 13. bxa7 cxd4! 14. g4 Nc5 15. Qe2 d3 16. Qg2 Nh4 17. Nxh4 Bxh4 18. Be3 Be7 19. b4 Ne4 { and Black would have excellent compensation for the pawn }) 12... bxc5 (12... a5! $15 { A very common motif and useful to remember. If white has extended with c5 and b4, he needs to be ready to meet a Black ..a5 with the move a3 to maintain his structure. Here (and in similar positions) a3 would be met simply by axb4 and the rook is hanging on a1 }) 13. bxc5 Qa5 14. Bd2 (14. g4! { Again g4! is available as the knight is still short of squares } 14... Nh4 15. Nxh4 Bxh4 16. Bd2 Qd8 17. g5) 14... Qb5 15. Qc2? { Strangely undervaluing the prospect of a protected passed pawn. After Qxb5 cxb5, the White pawn on c5 is worth much more than a pawn, and could almost be worth a knight! } 15... Bd8 (15... Nxc5!! { Is a tactical shot that works here, beacuse of the weakness of the dark squares near the White king } 16. dxc5 Bxc5+ $17) 16. g4 Ne7 17. Ng5 g6 18. Nc3 Qc4! { A good move. The most active square for the Black queen } 19. Rf3?? { Oops. Forgetting about d4 } (19. Qa4 Qxa4 20. Nxa4 $14) 19... Qxd4+ 20. Be3 Qc4 21. Rh3 d4 (21... h5! { Would also be strong, availing the knight of the f5 square once again } 22. gxh5 Nf5) 22. Nxh7!? { Forcing Black to find a tricky move if he wants to keep control of the position! } 22... dxe3?? { Not easy, but Nd5!! defends twice aginst Nf6 whilst simultaneously attacking two of White's pieces. Not bad for one move! Never mind the rook on f8, especially in such a sharp position- control is all important, not the material. } (22... Nd5!! 23. Nxf8 Nxf8 $19) 23. Nf6+?? { Sometimes sacrificing the queen isn't just desirable, it's absolutely necessary!! And again, it comes down to concrete calculations where the value of pieces are no longer absolute, but in a state of flux } (23. Ne4!! Qxc2 24. Nhf6+ Nxf6 25. Nxf6+ Kg7 26. Rh7#) 23... Nxf6 24. exf6 Nd5 25. Rc1 Nxc3 26. Qxc3 Qxf4 27. Rg3 Qf2+ 28. Kh1 Bc7 29. Rg2 Qf3 30. Re1 Bf4 31. Kg1 Qh3 (31... Rfd8! $19 { and Rd2 next }) 32. Qd4 Rfd8?? (32... Bxh2+! 33. Rxh2 Qg3+ $17) 33. Qxf4 Rd5 34. Rg3 Qh8 35. g5 Qh5 { 1-0 Black resigns. } 1-0
