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,
Let's see: after
9...Ne5 10.bxc3 Nxc4 11.Qd4
Black can play instead of 11...f5:
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;
(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)
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!
May your pieces harmonise with your Pawn structure and
your sacrifices be sound in all variations
