Black responds correctly: take the pawn and hope for the best against e2-e4! } 10... dxc4 11. e4?! (11. Nd2! { White is unable to do much with the "big center" whereas this at least wins back the pawn. } { [%cal Gg2a8,Rb6b5] } 11... Nd5 12. Nxc4 Nxf4 13. gxf4 Bb7 14. e3 $10 { The dark-squared complex of pawns complements White's remaining bishop and eyes the e5-square. }) 11... Bb7 12. Rfd1 (12. b3!? { This is the thematic way to play these positions, disrupting Black's queenside phalanx while opening another file. But giving up on dreams of recapturing the pawn is never easy. } { [%cal Ga2b3,Ga1a8] }) 12... b5 13. Ne5 Nxe5 14. dxe5 Nd7 15. Be3 Qc7 16. f4 Bc5 { Black trades pieces before White's attack can amount to anything. The f4-f5 threat is mostly symbolic, anyways, as the e5-pawn will collapse. } 17. Qf2 Be7 18. Rd2 Rfd8 19. Rad1 Nb6 20. Bc5 { White's insistence on forcing moves is helping Black complete the strategy of trading into a won endgame. } 20... Rxd2 21. Rxd2 Rd8 22. Rxd8+ Qxd8 23. a3 Bxc5 24. Qxc5 Nc8 25. Qe3 Qb6 26. Kf2 Kf8 27. f5 Ke7 28. Bh3 Qxe3+ 29. Kxe3 Nb6 30. Bf1 $17 { The game cuts out here, but Black has preserved the extra pawn in a way that restricts both of White's remaining minor pieces. The four-on-two on the queenside should give Black the win. } 0-1
