A00 Irregular Openings (1.b4 e5 2.Bb2 Bxb4 3.Bxe5 Nf6 4.e3 Nc6 5.Bb2 d5)

A00 Irregular Openings (1.b4 e5 2.Bb2 Bxb4 3.Bxe5 Nf6 4.e3 Nc6 5.Bb2 d5)

The game below was played in a team match called Mount Doom. The match consisted of 30 boards and it was played between Lord Of The Rings and Equipo Latinoamérica. I played on board 3 for Lord Of The Rings and unfortunately I lost both of my games against alfito2012. Those losses were quite meaningful because of the otherwise evenly played match. The match ended with a score 28.5 - 31.5.

The first 17 moves featured only small mistakes, but the evaluation after 9.h3 is a bit unclear, depending how deep in the analysis I allow the engine to go to, the evaluation is either slightly better or clearly better to me. I do have the better pawn structure, which I thought should work in my favor. After 18.Nd4 I have a decision to make and unfortunately for me, I made the wrong one. I had a chance to trade the knights, defend the knight with Bd7 or Qd7 or move the knight away, I chose to move the knight to e5, which tactically loses a pawn, like shown in game. I did not like the idea of trading the knights because then my opponent would have likely taken back with the c-pawn and improved his pawn structure. Maybe I should have played Bd7, because it would have kept the pawn structure the same and if alfito2012 would have taken my knight on c6, then I could just happily take back with my bishop and I think my bishop should be well placed at c6. After the game move 18...Ne5 my position falls apart and despite of my best efforts, I was unable to recover from the loss of the pawn. Actually the engine thinks that the move 18...Ne5 is actually the best move in the position and the loss of the pawn should not be all that bad for me. However, to my human eyes this does not look like a comfortable situation for me to be in. I guess the better pawn structure and the fact that my pieces are better than my opponent's give me enough compensation for the pawn. The bishop on b2, for example, seems to be very bad compared to its counterpart on b6.

The move that threw my position overboard was 27...Rad8 and the position went even worse for me with my next move 28...Qe7. After my 28th move the game is completely lost. I should really look for tactical possibilities harder than I have in every position because the move 27...Rxe3 is something that I might have seen in my younger days when I was more tactically aware than I am now.

Game number two. This was played in a team match called Kristina Fans VS Limitless Chess on 51 boards. It was played between Bergersen and Kristina Fans and Limitless Chess. I played on board 15 for Limitless Chess and won both my games on time because my opponent's account was closed due to cheating. The match ended with a score of 59.5 - 42.5 in favor of Bergersen and Kristina Fans. I was able to keep the game evenly fought until I played 17...Nd7, which started my final downfall.

During the remainder of the game my position only went worse and I was quite lost in the final position, even though material was even.
