While I do still keep correcting and perhaps improving on my previously posted games, this game may be something I have not shared in this blog before. I am maybe 90% sure that it has not appeared here before, the reason why I share this now, is that it was the next one on the list of analysed games in the database I am going through. It is actually a mixed bunch of games, containing both previously shared and games that have not appeared here before. I will mainly concentrate on making changes to the old posts, but these new games may appear from time to time. This game was played at Chess.com in a team match called EPIC MATCH. It was played between The King Attackers and DORU-66 & HIS BEST FRIENDS on 60 boards. I played on board 9 for DORU-66 & HIS BEST FRIENDS and lost both of my games. The final result, however, was 51.5 - 68.5 in our favor! For the first 23 moves the game both players made reasonable moves, but then it was me who messed up and then it was quickly over for me.

In the game I played 24.Nexd4, which was the game losing blunder. I did continue playing for awhile, but the game continuation shows quite well how hopeless my task was. The game ended in a position where the material is even, but I could not prevent my opponent from queening the a-pawn without giving my queen for it.

The game I am sharing today was played in a mini-tournament called "ichthus's mini-tournament v" and it was held at GameKnot. It was an invitation only mini-tournament and 9 players took part in it. This has been so far the only mini-tournament I have been able to win. My opponent, ichthus, who created the mini-tournament was on 5th place in the final standings. The first real mistake according to Stockfish 8 64 POPCNT is 12...Kh8, though 8...Qa5 may need to be looked at more closely, better moves were probably available for my opponent on move 8. Not sure what the idea behind the move 12...Kh8 was, it seems to be just wasting time.

I replied with 13.g4, and my plan was to try and open files on the kingside. Ichthus then tried to get some play on the c-file by moving the rook from a8 to c8. I should have then played 14.a3, according to the engine at depth 32. I played 14.b3 in the game and the advantage I had before vanished into thin air. A few moves later my opponent threw the game away when he moved the knight to g3 on move 17.

The blunder by my opponent allowed forced mate, starting with 18.Qh6+. After seeing my 18th move, ichthus resigned, which was probably the best thing to do in that position.
