B16 Caro-Kann: Bronstein-Larsen Variation (1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nf6 5.Nxf6+ gxf6)

B16 Caro-Kann: Bronstein-Larsen Variation (1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nf6 5.Nxf6+ gxf6)

Today I noticed that Stockfish 9 had been released, so I downloaded it immediately and analysed this game with the new engine. I should test it against the previous one at some convenient moment by putting them to play against each other with the same settings. The game I am sharing today was a 5 minute game that was played at Chess.com. The move 5...gxf6 is an interesting idea, but if I ever were to play this while controlling the black pieces, I would go with 5...exf6 as it would keep the pawn structure in better shape and it would open the a3-f8 diagonal for the bishop, where it would want to go after gxf6 as well. Therefore, in my opinion, 5...exf6 is more natural one. It also the move that the engine prefers and actually thinks that White should be clearly better after 5...gxf6 at depth 34. Then the game continued with other moves that the engine does not really like, but the first position that I am going to take a closer look at is the one that arose after 8...Qe7. I played the really horrible move 9.dxe5 and the game might have ended after Kojjootti's reply, had he played 9...Qb4+ that is.

Kojjootti played simply 9...fxe5, which gave me time to play 10.Bd2 and solve my problems for the time being, save both the bishop on f4 and the one on c4. The next huge mistake was played by my opponent on move 18, when he played 18...Bxh6. While this was a blitz game and there was not that much time to think about the moves, still I think that a move like 18...Bxh6 would not have crossed my mind, had I controlled the black pieces because it just invites the queen closer to the king and thereby restricting the options that the black king has. I think if the bishops are traded it is in Black's best interest to let White to initiate the trading process. In that way Black would be able to get the king to g7 and have the idea of Rh8 in some situations.

From that bad decision my opponent did not recover from and I was able to eventually even checkmate my opponent on move 55.

The position after 5...gxf6 has seen quite a lot of play in Grand Master play, but I am only going to include some of the most recent examples to the publishing tool below.
