How to play

White moves first. Checkmate the opponent's king to win. The king is never captured.

King: one square. Queen: any direction. Rook: rank/file. Bishop: diagonal. Knight: L-shape (jumps). Pawns move forward one (two on the first move) and capture diagonally.
Castle (O-O / O-O-O) if the king and rook have not moved, the path is empty, and the king is not in, through, or into check.
En passant is allowed only on the next move after a two-square pawn advance. A pawn on the last rank must promote to queen, rook, bishop, or knight.
No legal move and not in check is stalemate (draw). Insufficient material, 50 moves without a pawn move or capture, and threefold repetition are also draws.

Controls

Select a piece to show legal destinations, then select a highlighted square to commit the move.
Choose a promotion piece when a pawn reaches the final rank. Castle by moving the king to its castling destination when legal.
While in check, only moves that make the king safe are available. Friend games use a per-move clock.

Strategy tips

Control the center, develop knights and bishops, and castle before starting a wing attack.
Before every move, scan checks, captures, and threats to reduce one-move tactical errors.
Judge exchanges by pawn structure, open files, and king safety as well as material value.

Difficulty differences

Easy randomly chooses from a lower-rated portion of candidate moves and can even miss mate in one. Normal searches two plies, while Hard searches three plies to compare longer tactical continuations.

Common beginner mistakes

Leaving the king in the center invites early tactics — castle quickly.
Attacking without checking checks, captures, and threats loses pieces.
Pushing random pawns creates weak squares — develop with central pawns.
