B20 Sicilian: Unusual White 2nd moves (1.e4 c5 2.b4 cxb4 3.d4 e6)

B20 Sicilian: Unusual White 2nd moves (1.e4 c5 2.b4 cxb4 3.d4 e6)

The game I am sharing today was played at Loimaa in a weekend tournament that was held there in February 2010. This game is from the 4th round and this was my second win in a row. On the first two rounds I lost my games, so after a rough start things were looking up again. On the last round I suffered another loss and it meant that I only managed to get 2 points out of the possible 5. I have not been one to like gambits, but when I am able to refute them, I feel quite happy. I will only go through some moments of this game and you can then view the full game with the game viewer. The first position I am going to take a look at arised after my fourth move 4...Nf6. In the position below my opponent played 5.f4, which is a first real mistake of this game. 5.c4 was a better alternative.

Then just a couple of moves later I played 7...Qa5 in the position below, briefly bringing the game into balance, or at least close to it. My opponent replied with 8.Nd2, making his position clearly worse again. 8.Ne2 was the better choice. I continued with 8...Be7, which is only good enough for a small advantage, 8...b3 was the right way to go and I would have been clearly better, had I chosen to play that move.

When we reached the position below, all of my advantage was almost gone. It was my move and I played 28...Na3, after which there was nothing left of my advantage.

It did not take long, however, until my opponent made the blunder that lost the game. In the position below my opponent played the horrible 30.Ng3, after which the game is lost for White. The correct move was 30.Rc1. To the move played in the game I replied with the strongest move 30...Rc3.

The game was not even close to being over just yet, because the game ended to my opponent's resignation after 51...Kf8. I have added a mate in two puzzle 744, mate in three puzzles 668 & 669 and mate in four puzzles 531 & 532 today.
