D26 Queen's Gambit Accepted: 4.e3 e6 5.Bxc5 c5 sidelines (1.d4 d5 2.c4 dxc4 3.e3 Nf6 4.Bxc4 e6 5.Nf3)

The game you can see below was played in the first round of the 28th Chess.com Tournament and the last game of mine in that first round finished only moments ago to my victory. That meant that I won the group number 137 with a score of 10/10!! With that win I also climbed my way back to 1900. I wonder how the next round will be as my tournament entry rating was 1733 which meant that I played in this group but will I be promoted to a higher group in the next round, is still a bit unclear to me. I hope that I will be getting higher rated people to play against so that I do not have that much pressure on winning every single game. Well luckily it might still take awhile before the next round starts as there are still around 3% games left in the first round. The tournament started September 1st 2014, so it took a bit over 3 months to wrap up the first round for me. I also hit my new peak rating at Queen Alice Internet Chess Club today and now the new peak is at 2169!! I might get it a bit higher yet before it maybe comes down a bit. I will share that game at some point. I have added more puzzles today to mate in one, two, three and five pages.
