Generally, chess puzzles will present you with a position and ask you to find the best move. There’s only one, and all other moves are losing. These are great, but I’ve been thinking of a different style of puzzle that I’d like to practice with. What I want is a chess position, then two moves presented as options; one is a blunder, and one is the best move. The idea is to train my ability to spot blunders, like regular puzzles train your ability to find forcing lines.
