Black against world no 4 V.Kramnik is usually a bit of a challenge, and the game today was no exception.
1.c4 e5 2.g3 Nf6 3.Bg2 h6 4.Nc3 Bb4 is rightly categorized as an .uncommon opening., and we had to think right from the start. Somehow I got a difficult position out of the opening and during the early middle game it turned even more unpleasant as I had to withdraw one piece after the other. But despite white having all the space, the black pawn structure was healthy promising decent prospects long term (if I survived).
In the critical face Kramnik probably missed a few continuations maintaining a white advantage and the position got more dynamic and fairly balanced. I still had to find the best moves though. The complex game required an unusual amount of concrete calculations and we both drifted into time trouble around move 30. Kramnik shifted his attack to the queenside, but it was defendable for black. Just before the time control we repeated moves two times and as I could not find a healthy way out of the perpetual I took the third repetition. A highly eventful draw. I must have been too relaxed after the time control as I missed a fairly straightforward variation (Kb8 and Bc8) offering the chance to play for a win.
Anyhow, an exciting game with lots of good moves and some less good by both players.
Aronian, Karjakin and Svidler all won with black today and the first two joins Nepomniachtchi and me in the lead after three rounds.
Tomorrow I.m white against Karjakin, and I look forward to another game of chess!
