There is some nice positional play in this game as black. White was pressured and then stifled into a frustrating endgame + resignation. I am a much higher rated chess player in general than my opponent but we have similar daily ratings because ranking up in daily takes a long time so I won't gloat too much. But this was a fun game.
1-5: the trompowsky attack. Not an opening I see too often. It's like a d4 ruy lopez. Trading a bishop for a knight in the opening as white seems sketchy to me without good confidence in your endgame skills.
5.... Be6 : Not my favorite type of move but I wanted to get another piece defending d5 to maintain a presence in the center. Pretty much have half a bishop doing so but since I am down my queenside knight it seemed reasonable.
6... c6: more coverage on my central pawn. Opening up a break for my queen to go to b6 if necesscary.
6-8: developing moves.
9: dxe4: takes seemed better here since I have 2 pieces covering d5. I was starting to build some tactical ideas for the middlegame. The knight on f3 looked good to pin, b2 undefended.
10... Bg7: just a developing move, plus defending my double pawn. I now have the option queen or kingside as needed. Since my opponent had no immediate threats on my king I choose to wait.
11.... O-O: I saw no clear advantage for the queenside castle and always prefer kingside when feasible. My double pawn actually provides a nice fortification as it prevents knights from hopping onto g5. I also don't like a rook x-raying my central king.
12... b5: not a move I would normally make, but I had a tactic in the works and wanted to prevent c4.
13. bd5?: this is a mistake. My undefended queen is pinned and he can take a free pawn here. I saw this after and wasn't happy about it but luckily he didn't see it.
14... bh6: I did not want that rook on that square. Also prevent knights on g5.
15.... f5!: all my prior moves were leading up to this one. kick the knight and have an annoying pawn structure that my opponent can't do anything about.
16. Nxc5... just an intermediate move leading up to my plan. I have the initiative.
17. ....Bxf3: I will always almost make this move when given the chance. Crack open the enemy king and give him a double pawn too.
18-25: just threatening checkmate but that double pawn actually turned out to be kind of pesky.
27... bxf4 missed the zwischwenzug Rxf2+ for a free pawn.
I was fine taking this endgame with the queen trade based on my positional advantage. His light squared bishop was essentially a "tall pawn" due to my pawn structure. Had he capitalized on my mistake earlier this would not be the case. My opponent clearly got frustrated around move 30 by his lack of available moves and was unable to form a plan. He began speed moving for an eventual blunder and resigned. I kind of wished he played it out because it was a pretty complicated endgame (but very winning for black).
