Be3 c6 16. Ne1 Bxg2 17. Kxg2 Nd5 18. Nd3 Nxe3+ 19. Qxe3 Qd5+ 20. f3 Rfd8 21. Nf4 With an equal game 14... c5 15. dxc5 Rxc5 16. Nxd5?! Bxd5 16... Rxc1 17. Nxf6+ Bxf6 18. Raxc1 Qa8 19. Bxb7 Qxb7 20. Nd7 Rc8 21. Nxf6+ gxf6 22. Bh6-/+ Somehow both my opponenet and I calculated that my this line would lead to a position with one pair of rooks traded and my other rook on the 7th rank, which would be unpleasant for black. In this case, however, black is simply winning. 17. Qd2 Qa8 18. Bxd5 Rxd5 19. Qe3 Rfd8 20. Rxd5 Nxd5 21. Qf3 Nxf4 22. Qxf4 Bf6 23. Nd3 Qd5 24. a4 e5 1/2-1/2 [David Plotkin]
