[Kramnik indicated his plans against 3...d5 a few rounds later by 4.Qa4+ - see Kramnik,V (2791)-Vachier Lagrave,M (2715) /Hoogeveen/2011/ Giri said he was inspired by Nakamura's recent games against Kramnik and doesn't mind entering King's Indian territory. However, his opponent was certainly prepared, as Anish has already played this opening earlier this year.] | ||

[If only statistically speaking the main move here is 10.Re1 , but Kramnik played this a lot in the past. Suffice to say that after he beat Kasparov in Novgorod 1997 in this line the latter stopped playing the KID in classical games. However, lately Kramnik has been doing some experimenting in the Bayonet Attack. His recent choice here has been 10...f5 11.Ng5 Nf6 12.Bf3 | ||
|
(12.f3 was played in no less than 5 (!)
Van Wely-Radjabov games. The last one from 2009, annotated by Van Wely in CBM 129, illustrates the problems
Black has to face after 12...Kh8 13.Rb1 h6 14.Ne6 Bxe6 15.dxe6) | ||
