Interesting - the verdict on 11...f5 I think has stood for 100 years, until now! - but the best move probably isn't 11...Ncd6, or 11...f5, but 11...0-0. Let's see: after 9...Ne5 10.bxc3 Nxc4 11.Qd4 Black can play instead of 11...f5: [A] 11...Ncd6(?) White doesn't get the piece back but seems to get a strong attack through 12.Qxg7 Qf6 13.Qxf6 Nxf6 14.Re1+ Kf8 15.Bh6+ Kg8 16.Re5 Nfe4 17.Re7 as in Durao-Ferrera, 1994; [B] 11...0-0(!) 12.Qxc4 (12.Qxe4 b5 13.a4 c6 14.axb5 cxb5 15.Qd4 Nb6 16.Be3 d6 and White has nothing, as in a Dzindzhikashvili-Karpov rapid game) 12...Nd6 And maybe White's best try is now 13.Qd3, according to Gufeld and Stesko. I'll make a note on the page. Thanks for your prompt: if nothing else, I've discovered that these old lines are far from played out!
