user-1: Let's say that I have a pawn at b2 and a bishop at d2 and I want to capture the pawn on c3 with my bishop. The expression I used is bc3. However, it uses my pawn at b2 to capture the pawn at c3. I then tried b2c3, but it did the same.
How do you use bishop to capture the pawn at c3 with algebraic expression in this case?
[FEN "rnbqkbnr/pppp1ppp/8/8/8/2p5/PP1BPPPP/RN1QKBNR w KQkq - 0 4"]

1.Bxc3 (1.bxc3)

Lowercase letters ALWAYS refer to pawns/files. Uppercase ALWAYS refers to pieces. You need to use Bxc3 for "Bishop at d2"xc3.
