Kramnik played into a bad variation, but Jakovenko missed the best response: e6! (analysis by Fier for ChessBase). It looks like a difficult test.

[yanquis1972]

hard to credit analysis when rybka picks up e6 @ depth 14 (/17) with a decisive score 3 ply later.

[Marc MP]

Hi Jon,

I think there is a problem because 1.e6! Qxc3 2.Qc7?! only draws I think, and some engines spot that move quickly (thinking it is winning or advantageous). Only 2.Qd6! is winning if I'm not mistaken.

I think the John Dalhem/Rybka analysis does show that Rybka know that the Qd6 follow up is the stronger!

2. Qd6 may be a better test move for engines, since you can select 1. e6 w/o seeing that it's winning.
