Example review
This is what one moment looks like
An invented position, not anyone’s game. Blunderbase finds the moment in your own completed games, asks what you were thinking, and answers with what the engine can actually prove.
The move that was playedWhat the engine plays instead
What the learner wrote
I wanted to open a line for my light-squared bishop before castling.
Engine-backed explanation
Your idea
Opening that diagonal is a real plan, and it is worth having. It just was not the question the position was asking.
What happened
Black's last move attacked the bishop on b5, and d3 left it there. Black can answer axb5 and win a bishop for nothing.
Stockfish's moves: Ba4, Nf6, O-O
Next time
When a pawn moves next to one of your pieces, ask what it is attacking before you do anything else.
Think back
What was the last move Black made, and what did it touch?
