Alexander Grishcuk shared his impressions on the game against Vassily Ivanchuk - one of the peaceful encounters of Round 5 of the Grand Prix. 

"Actually it was a bit hard to play today because I was completely sure that today was a rest day and I actually woke up today not knowing when was the rest day - today or tomorrow. But it's OK, maybe it's better, because otherwise it's stupid to wake up early just to find out that the round won't be played..."


"Here Vassily made a quite rare move 11.h4 (the position from Grunfeld defence before this move has been played at high level for a lot of times, including in Grischuk's games - CN). I don't know maybe it's equality here, my further moves were very natural: 11..е6, 12...Qh4.

The critical position emerged after 17.Rad1.

First I wanted to play 17...Bе5, but then I didn't like  18.g3. And if I take on g3, he will take, I take 19...Qхg3+, 20.Qg2 and I  think white has quite promising position. The computer will probably easily defend for black but for a human being it's quite unpleasant. That's why I decided to sacrifice the exchange.
17...Rac8. Here I expected him to take the exchange immediately with a very complicated position, but instead he made I think a quite strange move: 18.d5. It gives black just a huge choice: 18...Nе5, 18....Nа5, and even taking on d5 is possible. I couldn't find any advantage for me, so played what I thought was a safe option:
18...Na5 19.Bb5 exd5 20.Bg5 Qh8. Now if taking exchange I will always have some real compensation. 
21.Kf2 Bf6 22.Rh1 Qg7 23.Bh6 Qh8 24.Bg5 Qg7 25.Bh6 Qh8 26.Bg5 Qg7 1/2
The key point was that if repeating playing 24.Bf8, 24...Bh4+ 25.g3 follows and now a very important intermediate move 25...dе!, and black stands much better. So Vassily was forced to agree on a threefold."
