Nf3 d5 3. exd5 cxd5 4. d4 Bg4 { Here there are a few other moves, the main ones Bf5 or Nc6 which I usually play but this version here can be fine as well. } (4... Nc6 5. c3 a6 6. Bd3 Bg4 7. Bf4 e6 { This variation is more about stopping White from doing what they want. Nc6 stops the tempo with Bb5+ and a6 prevents the pin. }) (4... Bf5 5. c4 e6 6. cxd5 exd5 { The down side here is having an IQP although both sides have it so it isn't as bad. } { [%csl Gd5,Gd4] }) 5. Be2 (5. h3 Bxf3 6. Qxf3 e6 7. c3 Nf6 8. Bd3 Bd6 9. Qd1 O-O 10. O-O) 5... Nc6 6. O-O $10 Nf6 7. Nc3 e6 8. Bg5 Be7 (8... h6 9. Bxf6 Qxf6 { Taking allows for more pressure on d4, once the Knight on f3 is removed there will be one less defender as well. The recapture with the Bishop mean White's Bishop will be hitting a pawn chain and not very effective. } { [%cal Gf6d4,Gc6d4,Gg4f3,Rf3d4] }) 9. Bxf6?! Bxf6 { This has the same issues as h6 takes and Queen takes only now Black will have an extra piece attacking. } { [%cal Gf6d4,Gc6d4,Gd8b6,Gb6d4,Gb6b2] } 10. h3? Bxf3 11. Bxf3 { White has lost the f3 Knight who was defending d4. } { [%csl Gd4][%cal Gf6d4,Gc6d4] } 11... Nxd4 12. Re1 O-O { There is only one good move here, because the e6 pawn is pinned the d5 pawn is hanging. Black must castle. } (12... Rc8 { For example.. } 13. Bxd5 O-O 14. Bxb7 { The -2.5 advantage is now -1. } 14... Rb8 15. Be4 Rxb2 16. Na4 { Much more ugly of a position than when Black castles first before the attack. }) 13. Qd3 { This makes sense to however the computer gives another -0.5 to Black when it is played. } (13. Bg4 Rc8 14. Rb1 Qa5 { [%cal Gg4c8] }) 13... Qb6 { Connecting the Rooks and getting the Queen into a long range attack and defense position. } { [%cal Gb6d4,Gf6d4,Gb6b2,Gf8d8,Ga8c8] } 14. Rab1 Rac8 15. Na4 Qc6 { The threat is to capture on f3 with check forcing the Queen to take or the pawn and wreck the structure, at the same time the Knight on a4 is under attack and must be moved. } 16. c3 (16. Nc3 Nxf3+ 17. Qxf3 b6 { Black is still much better but doesn't have the advantage of a full piece. }) 16... Nxf3+ 17. Qxf3 (17. gxf3 Qxa4 { The Knight is lost and the pawn shield is broken, Qxf3 is best. }) 17... Qxa4 18. Ra1 Qc4 { The Queen is quite safe here, the only option to attack it would be b3 but that hangs a pawn. } 19. b3 Qxc3 20. Qxc3 Rxc3 (20... Bxc3 { I missed the recapture with the Bishop since it was on premove with the Rook, we were under 50 seconds at this point. } { [%cal Gc3e1,Gc3a1] }) 21. Rac1 { [%cal Gf8c8,Gc3c2] } 21... Rfc8 { I preferred the position of doubled Rooks on the C file in the end. } 22. Rxc3 Rxc3 23. Rb1 b5 24. a4 a6 25. axb5 axb5 26. b4 Kf8 27. Ra1 g6 28. Ra8+ Kg7 29. Rb8 { This looks like a strong move, capturing a pawn and defending the passer from the front. This turns out to be the nail in the coffin as the Rook on b8 is too far away to assist the King. } 29... Rb3 30. Rxb5 Bd4 31. g3 Rb2 32. Kf1 Rxf2+ 33. Ke1 Rb2 34. g4 Kf6 35. h4 h5 36. g5+ Kf5 37. Rb7 { The pawn can never make it to b6 due to the double capture and if White's Rook leaves the pawn it is lost immediately. The pawn is more of a liability to White since the Black King can continue to work on the King side while White's King is trapped on the 1st rank. } { [%cal Gb2h2,Gb2a2,Gf5g4,Gg4h4] } 37... Kg4 38. Rxf7 Rxb4 39. Rf1 Rb2 { 0-1 Black wins. } { White resigns, both pawns will be lost and there is no defending 4 pawns even with a Rook. } 0-1
