also a very inventive chess player. Now he surprised his opponent already on
the third move. Earlier this position was played only in three games with the
participation of unknown chess players. And a week later after this game the
move 3...e6 was applied in Kasimdzhanov,R (2690)-Naumann,A (2535). The first
time this move was used was in 1934 in the game Yudovich,M-Freiman,S/Leningrad

chess programs are skeptical about this decision. I think, Nikita made this
move without preliminary preparation for the game. He was surprised with the
early unusual decision of his opponent and spent a lot of time in the opening..
. But I think, now Nikita could surprise Maxim. It is a very rare event in
modern chess, when the game turns into a battle between people, not computer
analysis. This game was played in the last round of the prestigious tournament
with a big prize fund. We can admire the courage of both players! Bravo!

players always dream about being able to play Bg7-h6 at some stage, which is
now unlikely to happen. And then there is the weakness of the square g6. This
might seem irrelevant but as black very much wants to play f7-f5 it actually
is of some importance.   If black wants to play h7-h6 there is the important
question of moveorder. It seems to me he should play all the usual moves first

something on the Q-side(play b2-b4 eventually) as 11.a3 a4 is bad. If black
