1. d4 d5 2. e3 Nf6 3. Bd3 Bg4

This shows that white's third move is pre-mature. After 4. Nf3 the knight is pinned.



4. Nf3 e6 5. c4 c6 6. O-O Nbd7 7. Nbd2 Bd6 8. b3
O-O 9. Bb2 Re8 10. e4 dxe4 ?!

Black could have showed up white's 3.Bd3 with 10...e5! White has insufficient control over the e5 square as his king knight is pinned. After 10...e5, black has the upper hand.


11. Nxe4 Nxe4 12. Bxe4 Nf6 13. Bc2 c5 14. h3 Bh5 15. dxc5 Bxc5 16. Qe2 e5
 
Very provocative. Black is counting that white will not be willing to compromise his king-side with the next move

 17. g4 Nxg4

Unfortunately the sac is necessary. 17... Bg6 18. Bxg6 hxg6
19. Nxe5 Nd7 20. Qe4 Nxe5 21. Bxe5 f6 22. Rad1 Qb6 23. Qd5+ and white has unpinned his queen.

18. hxg4 Bxg4 19. Rad1 Qf6 20. Be4 Qf4

Threatens perpetual check with Qg3, Qh3 etc. 

21. Kg2 Re6


21... f5 looks promising but fails to 22. Bd5+ Kh8 23. Rh1 ! (Not 23. Bc1 Bh3+ 24. Kh1 Bg2+ 25. Kxg2 Qg4+26. Kh1 Qh5+ 27. Kg2 Qg4+ with perpetual)  23... e4 24. Bxg7+ Kxg7 25. Qb2+ Kg6 (25... Kf8 26. Qf6#) 26. Nh4+ Kh5 27. Bf7+ Kg5 28. Qg7#) 


22. Rh1 h6

Might as well play ...h5 although black is still lost. 22... h5 23. Bc1 Qf6 24. Bg5?? Bxf3+  wins back a piece

23.Bc1 Qf6 24. Rd5 Qe7 25. Be3 Bd4 26. Qc2 Bxe3 27. fxe3 Rf8 28. Rd2 Kh8 29. Rf2
f5 30. Bd5 Bxf3+

Black should keep pieces and complicate matters with 30... Rg6 31. Nh4 Rg5

31. Rxf3 Rg6+ 32. Kf1 e4 33. Rf2 Rg3 34. Qc3 Qg5 35. Bxe4 Rxe3 36. Qd2 Rd8 37. Bd5 Rde8 38. Bxb7 ?  f4 !


Alternatively 38...Re1+ 39. Qxe1 Rxe1+ 40. Kxe1 Qe7+ 41. Kd2 Qxb7 with good chances for a draw in the Q v 2R ending as the white king is too exposed.

after 39. Bf3

39. Bf3

















White's pieces are not organized to capitalize on the extra piece and his king is exposed to checks. Black has good chances with 39....Qg6

39...Qe5?


39... Qg6 Intention to check on b1 and g6 40. Rg1?  Re1+ 41. Qxe1 Rxe1+ 42. Kxe1 Qxg1+and black wins.

40. Rh4 ( to answer 40...Qb1+ 41. Kg2 Qg6+  with 42.Rg4) but now black has 40...Qg3 forking the rook on h4 and bishop on f3. Other moves like 40. Bg2 loses to Qb1+

 40. Rh5

White wins as his king can find shelter on the king-side

 Re1+ 41. Kg2 Qf6 42. Qd3 Qa1 43. Kh2 R1e3 44. Qd5 Qe1 45. Rg2 Qc3 46. Qf7 R3e7 47. Qxf4 Re6 48. Bd5
Rf6 49. Qg5 1-0
