Chessort is a unique chess training game that flips the typical tactics format: instead of finding the single best move, you are given four candidate moves suggested by the engine and must sort them from best to worst by their evaluation. This trains a different skill — comparative evaluation and understanding why one move is better than another — rather than pure calculation.

The format rewards positional understanding and evaluation skill over tactical sharpness, making it a useful complement to conventional tactics trainers. Players who can correctly rank moves develop a better intuition for why the engine prefers certain structures, piece placements, and plans.

Chessort is free and available daily with a new puzzle. No account is required. It is particularly interesting for players who already solve tactics competently and want to sharpen their comparative evaluation skills.
