Ne5 Nxe5 16. dxe5 Kh8 17. a4 $2 {At first sight White's position looks quite good. He has the better Bishop, and is threatening to take the initiative on the Queenside with Pa5. The sequel will show that he is being too optimistic} ( 17. g3 Rg8 18. Kh2) 17... Rg8 18. Qd2 gxf4 $1 19. Rxf4 (19. exf4 Qh4 20. Kh1 Rxg2 21. Kxg2 Rg8+ $19) 19... Qg5 20.
