B32 Sicilian: Löwenthal and Kalashnikov Variations (1.d4 c5 2.dxc5 e5 3.e4 Bxc5 4.Nf3 Nc6)

This is one of the ten games I played in the round one of the 28th Chess.com Tournament. The rating range for the group was 1601-1800. The next round of the tournament still has not begun as 119 games still remain to be played on round one while I type this. This game started to go wrong for my opponent early on, especially after the move 12...b6 which was a big blunder that lead to a loss of a bishop for a pawn. After that blunder there was no real hope for a comeback for my opponent even though I may not have played the rest of the moves in the game optimally.

The amount of games I play simultaneously seems to have stabilized to 278 games which is at the moment a bit too much as I am not able to give enough attention to every game. I have tried to move faster recently but I have still not managed to get my games to a point where there would be less games in which I have to move than those where it is my opponent to move. I have updated mate in one, two and three puzzle pages today.
