Black momentarily masters the important e4-point, but White prepares interesting counteractivity. 13.cxd5 exd5 14.dxc5 (Presumably 14.Ba6 gave more solid play.) 14...Ndxc5 15.Ne5 Qh4 Threatening 16...Nxd3 17.Qxd3 Qxf2+ etc. If 16.f3? then 16...Nxd3 etc., just the same. 16.Ndf3 Qh5 17.Bb5! a6 18.b4 axb5 19.bxc5 Bxe5 20.Bxe5 bxc5 21.Qxb5 Bc6 22.Qa6 g5!?
(Clearly better was 22...Qe8! with the threat of ...Rc8-a8 as well as ...Bc6-b5-e2xf3.) 23.Bd4! Very good. 23...f4 Again not the best. (Precise calculation of two interesting variations was required. 23...cxd4 24.Rxc6 Ra8 25.Qb5; and 23...g4 !?! 24.Ne5 g3! 25.hxg3? cxd4 26.Nxc6 dxe3 27.Ne7+ Kh8! with a beautiful mating attack. If instead on move 25 White captures not with the h-pawn but with the f-pawn, he achieves a clear advantage.) 24.Bxc5! Nxc5 25.Rxc5 g4 26.Rxc6 Ra8 27.Qb5! Rab8 28.Rb6 Rxb6 29.Qxb6 gxf3 30.Qe6+!
30...Qf7 31.Qxd5 Qxd5 32.Rxd5 fxg2 33.Kxg2 fxe3 34.fxe3 Ra8 35.Rd2
(...) and Black did not resign until the 52nd move. 1–0
