Click on a chess piece to show its possible moves. Click on an green square to make a move of a chess piece. Checkmate the king to win. Check - The king is in danger and you must protect him either by blocking the check, capture the threatening piece or get away from check. Checkmate - The king is in danger and cannot be either protected nor get away from check. Stalemate - Either 50 move rule or king cannot move but is not in check. Castling - When there are no pieces between the king and the rook and they haven't moved yet, the king can castle by moving two squares to the rook and by moving the rook over a king next to him on the other side. If either a rook or a king has moved and return back, castling cannot be performed. Queenside castling can be called "Castle Long".
I took the chess piece and board images from Wikipedia, vectored the pieces, took chess.com sfx from YouTube with savefrom.net No 'en passant' for now, sorry.
