I just finished a game. I got into a pretty convenient position at move 17 (I play white):
I noticed that in order to checkmate, I only need to remove the black bishop from protecting e7 and then I can get my knight there and checkmate. So, I figured that if I push the pawn on the b file to the c file, there's a good chance my opponent would capture the knight on c3 "for free" and would allow me to checkmate. My plan worked like a charm but the computer analysis tells me that was a blunder.
I do realize that it might not have been the best move if I would have played against a GM. But in this scenarios which we're both around 1400+, this seemed like the most logical move.
So, I wonder how could I really trust an engine if it only plays GM level and doesn't understand the potential move for a human on a specific level.
Here's the PGN for the game with the analysis:
