This blog post was mostly typed when I originally shared this game, so the info about the tournament is a bit out of date. Like previously, I have changed the static positions into living diagrams. This game was played on the first round of the 2015 October Grand Split Three Seven I 1800+ tournament. The tournament is still in progress at Red Hot Pawn. I was not able to advance to the second round as I was on shared 6th place in the last standings of group 1. Only the winner of the group advanced to the second round. My opponent in this game, funkydunky71, was 5th in the final standings of the group. While I managed to get 46 points, funkydunky71 was able to get 50 points. The winner of the group, cenerentola (2570), was able to get 82 points.

For the first 18 moves both players were able to avoid big mistakes, but then when it came to my 19th move, the first blunder of the game raised its ugly head. The position in which I played 19.Nd5 can be seen below. It would have been a better option for me to play 19.Qb3+.

The advantage that my opponent was able to gain due to my 19th move fizzled out a few moves later and was completely non-existent after 25...Qe5. The next mistake was played by funkydunky71 on move 31 in the position below. Had my opponent played 31...Qe5, the position would have remained about even. Actually it was probably the only saving move for funkydunky71.

Funkydunky71 played 31...Rd8, after which I was on the clearly better side of the board. I continued with 32.b5 and my opponent blundered again by playing 32...Qe5 in response. Now I had a winning position, but unfortunately I was not able to see the correct continuation. I chose to play 33.h3 because I was worried about my back-rank weakness. The winning continuation would have started with the move 33.Qxe5. The move I played was only good enough for a draw. The remainder of the game only featured small mistakes, but ended in an even position as draw was agreed upon after 50.Rb2.
