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.
