Learn chess properly
Every idea is shown on a board you can step through — arrows for the plan, then a puzzle to prove you got it. Flip on Kid mode for a five-year-old: shorter words, bigger targets, and only the courses a beginner needs.
Work down the list. Each one assumes the one above it.
The things worth having memorised, in the order you use them.
Say one of these before every move.
Movement reference
Pick a piece, then click any square to drop it there. The board recalculates its reach, so you can see exactly how much power a knight loses in the corner and a bishop gains in the middle.
Click any square to reposition.
Each piece on d4 (pawn on e2), empty board — maximum reach.
Practice board
Full rules — castling, en passant, promotion, checkmate and stalemate. Illegal moves simply won't go. Start on Puppy so he can win, and move up.
White to move
Click a piece, then click where it goes.
Material even
Amber dots show every legal move for the piece you picked. If a square has no dot, that move is against the rules — usually because it would leave your king in check.
