Chessguessr presents a position from a real master game and asks you to guess the sequence of best moves that followed — the next five moves in the actual game. You input each move on the board and receive feedback on how close your guesses are to what was actually played, testing both tactical and strategic understanding.

The format bridges the gap between passive game study and active calculation: rather than just following moves you already know, you have to independently find lines and then discover how they compare to what strong players actually chose. Each puzzle includes context about the players and event.

Chessguessr is free and requires no account. A new puzzle is available daily. It is particularly enjoyed by players who are studying master games and want an interactive element to their game review practice.
