Rules

The rules people get wrong, written plainly. Each one shows what happens in a tournament and what happens here.

1. 1FIDE chess rules explained simplyThe official chess rules in plain words: castling, en passant, promotion, stalemate, illegal moves and touch-move, with a playable study and puzzles.
2. 2Illegal move in chess: what counts and the penaltyAn illegal move is any move the rules forbid. See what counts, the exact FIDE penalty, and three positions where only one move on the board is legal.
3. 3Touch-move rule in chess (FIDE and USCF)Touch a piece and you must move it. The FIDE wording, how to say j'adoube, what USCF does differently, and three puzzles where the touched piece wins.
4. 4Play chess without move hints: why it mattersLegal-move dots do part of your thinking. See what changes when they are off, the moves players miss without them, and three positions to test yourself.
