ChessRiddle: Chess Trainer

No move-guessing: the board stays static while you calculate the whole line. Mixed Mode trains you as close to a real game as it gets — validated by Stockfish.

ChessRiddle is not your average tactics trainer. Instead of guessing single moves, you train real calculation – as close to a real game as possible.

WHAT MAKES CHESSRIDDLE DIFFERENT • The board stays static: you calculate the whole line in your head instead of trying moves on the board. • You enter the complete variation tree to prove you calculated the entire line – no move-guessing. • Mixed Mode: tactics and positional play combined, just like a real game – you first decide whether the position is tactical or positional. • Every solution is validated server-side with Stockfish.

That sets ChessRiddle apart from the hundreds of pure tactics trainers where a well-guessed first move is enough.

SIX TRAINING MODES • Tactics – Find classic combinations and tactical motifs • Mixed – Tactics and positional play in one mode: assess first, then solve – just like at the board • Pieceless – Solve puzzles without visible pieces and train your board vision • Visualization – Calculate announced moves (pre-moves), then solve the position • Opening Blunder – Spot and punish typical opening mistakes • Position Evaluation – Estimate who stands better

TRAINING PLANS Structured training sessions of warm-up, main part and cool-down – automatically assembled by duration and focus.
