Bd3 { This, the Exchange Variation is an old line that has, in modern time, been somewhat revived. White's plan often involves a K-side attack, using the e-file to bring his Rs into the attack. Black's main plans are to launch a minority attack in the Q-side coupled with play in the center.pieces to equalize the position.} Nc6 5. c3 {This leads to a Queen's Gambit Declined structure in which the colors are reversed.} Nf6 {This is the old main move that has experienced some new developments. Today 5...Qc7 has been suggested.} 6. h3 g6 7. Nf3 Qc7 8. Qe2 Bg7 9. O-O O-O 10. Bg5 (10. Ne5 Nxe5 11. dxe5 Nd7 12. e6 {Draw agreed. This non-game was played in Klaric,Z (2410)-Garcia Gonzales,G (2495) Havana 1986. A likely continuan would be...} Ne5 (12... fxe6 13. Qxe6+ Rf7 14. Qxd5 {favors white.}) 13. exf7+ Rxf7 14. Qe3 Bf5 {Black stands well.}) 10... Nh5 11. Qd2 e6 (11... f6 {is the usual move.} 12. Be3 e5 { White should play 13.dxe5 and 14.Be2, but hlack would still be better.} 13. g4 e4 14. Be2 exf3 15. Bxf3 f5 16. gxh5 f4 17. Bxd5+ Kh8 18. hxg6 Bxh3 {Black soon won. Pershin,D (2190)-Matlakov,M (2676) St Petersburg RUS 2013}) 12. Re1 b5 {Stronger was 12...e5} 13. Na3 {There was no reason at all to avoid 13.Bxb5} Re8 {This iffer if the b-Pawn us even worse than last move now that white can play 14.Nxb5 with a practically decisive advantage. Correct was 13...a6} 14. Re2 Bb7 {Again, the offer of the b-Pawn is a very bad idea andm againm white should have taken it.} 15. Rae1 Bf8 16. Nc2 Na5 17. Na1 Nc4 {Finally! The issue of capturing the b-Pawn is resolved, but it turns out it's only temporary.} 18. Qc1 Nd6 {Black needed to play the thematic ...f6 because now white can generate an attack with 19...g4!} 19. Bh6 Ne4 {This allows the capture if the b-Pawn (again!), utt, as usual, white ignores the possibility.} 20. Bxf8 Rxf8 {A natural recapture, but 20...Nf4was stronger/} 21. Bxe4 { Guess what white should have played.} dxe4 {Now the position has been clarified and black can claim a small advantage that grwos into a decisive attack.} 22. Ng5 Nf4 {[%mdl 2048]} 23.

This time taking the b-Pawn would be very bad. It's ironic that the b-Pawn ends up being vital to black's victory.} 29. Qe3 (29. cxb4 Qc1 30. Qf3 Qxb2 31. Nb3 Rac8 {wins after} 32. Rxd2 Rc1+ 33.

This was not an especially well played game ( Accuracy: White = 28%, Black = 50%), but the fate of black's b-Pawn made it interesting.} 0-1
