Still making some changes to my older posts... Like changing the names of the openings used in the games to correspond the opening classification used by Deep Fritz 14. This game was played in a mini-tournament called "dim_weasel's XIV". There were 5 players playing in this mini-tournament and I was third in the final standings. I was on third place because I had a better tie-break than players who finished on 4th and 5th places. We all were able to gather 2.5 points in 8 games. My opponent and the creator of this mini-tournament, dim_weasel, was 4th in the final standings. A player called jug_head (1971) won the mini-tournament with ease, jug_head won all of his 8 games. The mini-tournament started on January 18th, 2016 and finished on July 9th, 2016.

My position started to go down the drain when I played 17...Bc6 in the position below. I should have played either 17...Rc8 or 17...Qa5 in order to have a chance to play for a draw.

I might have not been lost after my 17th move, but when we reached the position below and I played 24...Rfd8, my position was lost. Dim_weasel did not use his chance and instead lost most of his advantage by playing 25.f4. 25.Rd1 was the best choice for dim_weasel.

The game continued with the moves 25...Qc7 26.Rd1. With my 26th move I made the losing blunder Ne8. The game ended quickly after that as I resigned after seeing the position after 28.Qxb7.

The game below was played in the first round of the 2015 October Grand Split Three Seven I 1800+ tournament that is being played at Red Hot Pawn at the moment I type this. I have 35 points which puts me in 7th place, but I can still finish on third place if the remaining games go my way. Admittedly I also require the help of other players in order for that to happen. I am actually also the 7th highest rated player of group 1, so I am pretty much doing as well as can be expected. InvaderOfRome has currently 29 points, which puts him on 9th place, but because he has a better maximum possible score than me, he can still overtake me and many others when more of his games start to finish.

My 10th move b6 in the position below was the first step towards problems. I should have played 10...h6 instead.

The only way for InvaderOfRome to take full advantage of my mistake would have been to reply with the move 11.Qd5. In the game my opponent chose to play 11.Qb3, which allowed me to stay in the game. The game continued rather evenly until I played 16...Be5 in the position you can view below. 16...h6 was the correct way to go, at least according to Stockfish 8 64 POPCNT.

InvaderOfRome answered by playing 17.Qd3 to which I replied with the horrible move 17...Rb7 and I was in quite a hopeless position after that or I would have been, had my opponent found the strongest move. InvaderOfRome played 18.f4, which let me off the hook and I could have fought for the draw with accurate play. The game continued evenly for awhile, but with my 21st move I threw away the game. I played the huge blunder 21...f5 in the position below.

Had I played 21...Rd7, I could have stayed in the game. My final downhill started with my 21st move and after the move 27.Rxc6 I thought I had to accept the loss, so I resigned.
