Krush,Irina (2473) - Chen, Zhu (2549)
?? Bank Ataturk International Women Masters Tournament (1) (Notes: Krush)
1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 dxc4
Even thought there was not much time to prepare for the round beforehand, since the pairings and the colors were determined a short time before the round, I thought what she chose was the most likely choice by Zhu Chen even before coming to the tournament. She takes dc4 in Slav.
5.e4
This is Geller(-Tolush) Gambit and it is the first time I have ever played it. But the problem is that black has to protect the pawn and now it is really a gambit! Of course a4 is the main choice here but I would like to play a position which was less well-known. Almost no one plays this anymore and she could probably not have any specific preparation for the Geller Gambit. I even have the intentions of playing Geller Gambit before coming here. This variation was popular in 70s in 80s and I know that Kasparov has some games with this variation with white.
b5 6.e5 Nd5 7.a4 e6 8.Ng5
Another possible choice for white here is taking on b5. Actually that was not what I was intending to play. This is the critical main line, with the bishop strongly placed on b7 actually the main difference from the variation that I chose in the game so that was why I played the text move.

8...Be7
Apart from Be7 there are other moves as Nakamura played Bb7 in one game. Bb4 is another possibility. But her choice is the most solid one.

9.h4 h6 10.Nge4 b4
Up to now she was playing all these quite automatically but I am not sure whether she was prepared, trying to remember something or just finding these all by herself. Actually all the moves are quite normal.
11.Nb1 Ba6
12.Qg4
Qg4 is the move actually I was not very happy with. In Geller Gambit this is a quite thematic move. However, there are some nuances in this position compared to the normal ones. The normal position would like the normal line if the pawn is on h2 and the bishop on f8. Now, she has the Kf8
12... Kf8
Which I underestimated during the game but this move has some advantages such as when black captures d4 with her queen in some position than Nf6 would be no longer possible since when the king protects the g7 pawn with Kf8 then the discovered check winning the queen is no more possible.
13.Nbd2
After this move black might have played h5 and Qb6 which would possibly strong for black since white pawn on d4 is very dangerous to give up with the centralized queen attacking the e5 pawn at the same time. Actually I was intending to play Ng3 and defending the d4 pawn but I was not quite happy about what was going on.
13...b3
The move my opponent chose here looks good since it also trying to exploit the queen's absence from d1 with some threats like Nc2 etc. but against this move I saw a forced variation beforehand which was actually played...
14.Bxc4 Nb4 15.0-0 Bxc4
Actually I saw a funny possibility here since when black captures d4 there is the move Bxe6 against it. I call it funny because when black captures the bishop then Qf4 and whichever the square king moves now there is Nf6. I thought I can also sacrifice my rook for the bishop on a6 since I have two strong bishops some initiative which looks quite good for white since there is Qf5 here.
16.Nxc4 Qxd4 17.Qe2
After my early queen sortie to g4, I am now a pawn down but I thought it was okay since I have Qe2 and thought b3 would be an easy pawn for me to win back. Black has some development problems in the back rank with the knight and rooks but I did not notice Qd3 at first. This move is kind of problematic move because
17...Qd3
Forces me to exchange the queens but she is still a pawn down. I already noticed much earlier but thought it would not be a big deal since there is a compensation for the pawn because of my better-developed pieces as against her development problems with her pieces. But now I thought more about it I would not even care about the h4 pawn or black's possibility to develop the knight at a6, which is hanging since I have my pieces developed, b3 pawn would fall after Rb3.
18.Qxd3 Nxd3 19.Rd1 Nb4
Actually now it seems quite bad for black. Maybe black should have exchanged the knight with the bishop on d1.
20.Ra3 Nd5 21.Rxb3 Nd7 22.Rb7
The idea of black is to play Nb6 and slowly completing the development of the pieces so I have to get some measures against it. I have to play the rook to the seventh rank in the first convenient opportunity. This is a critical position in the game and I also thought about moving to h5 fixing the black pawns and avoiding the possible capture on b4. Also in order to prevent N7b6, playing a5 is another possibility but then black would play Rb8 to force the exchange of the rook and if I exchange my rook on b3 with the rook on b8 then I would have exchanged a very strong piece of mine with a very weak piece of her so I did not like those moves.
22...N7b6
23.b3
That is the point. If she captures on c4 then the strong knight on d5 has to be lifted from there so that was one of the best moves in the game.
23..Bxh4 24.Ba3+
Maybe Na5 and trying to capture c6 and maybe even a7 later on might be a simpler way to play but I liked the game continuation, which keeps the position more complicated.
Kg8 25.Na5
Seems a bit weird but why not? Maybe after g3 she could turn her bishop to d8 and then in some cases prevents Na5 later on...
25... f5
It is difficult to suggest a good defense for black. I can keep things simple as much as possible but I chose a continuation th`t would still keep the pressure on black. I was not going to capture the pawn first since if after 27.Nc6 I thought she was intending to play Rh7 and exchanging that bad piece with my rook on b7 but then I saw the variation in the game.
26.exf6 gxf6 27.g3 Bg5 28.f4 f5 29.fxg5 fxe4 30.g6
Although I am a pawn down there is a big pressure on black king after this move. It seems quite hopeless for black.
Re8 31.Nxc6 e3 32.Bb2 e5 33.Bxe5 Rxe5 34.Nxe5 h5 35.Rf1 1-0
I can say that the key moment is where I played Qg4 which I am not quite sure about . She should probably have focused on attacking only d4 pawn with Qb6.
