Guessing by position at move 12th you should have won that... I guess it is time to turn on good god Stockfish and see when you went wrong.
You actually applied pressue to d3 which was very weak and you were lucky your opponent captured with the bishop. But in my opinion even without the bishop needing to protect d3 Bxf3 was probably a mistake.
Reinforces their center with gxf3 and as there are no queens on the board I see nothing wrong with capturing towards the center.
Hello Yuri. Thanks for your post.
I was not lucky about my opponent capturing with his bishop. My opponent was foolish as I mentioned.
gxf3 is the best move he could make but it still has drawbacks. His pawns really limit is remaining bishop. My knight clearly outshines his bishop. To show for this, he only has a semi open g file
Today I played another game on chess.com's live server. the time controls were 30/0. After the game I done a quick analysis without the aid of the computer. Here are my annotations.
