Why we built it
Shahmat is the origin of the word checkmate. Engines have made chess impossible to keep up with and easy to misunderstand: they give you the score and never the reason. Every tool tells you that a move was a mistake. Almost none tell you why the position is what it is. We built Shahmat to understand what we don't understand.
