From club players to IMs

Where tactics meets ingenuity. ChessRiddle has become part of my daily training, and the most fascinating part are the evaluation puzzles — something I've never seen in any other application. I recommend it even to advanced players.

Chess puzzles are normally basic positions where you try to find the best first move of a sequence. ChessRiddle brings so much more depth and variety with variation trees, visualisation and pieceless exercises and thus trains the skills a good chess player actually must bring to the board.
