Validate chess moves from the starting position

Start from the standard chess position with White to move. You receive a list of attempted moves such as e2e4 (from-square, to-square). For each one, decide whether it is legal and, if it is, apply it and pass the turn; an illegal move changes nothing.

Implement normal movement for every piece: sliding pieces can't jump, knights can, pawns move one square (two from their starting rank through an empty square) and capture diagonally. A move may not capture a king or leave your own king in check. Castling, en passant and promotion are out of scope. At the end, print the board.
