Chess Tic Tac Toe

Chess Tic Tac Toe is a strategy game that combines classic Tic Tac Toe with real chess movement.

The board is 4x4. Each player has a bishop, rook, knight, and pawn.
On your turn, you either place a piece on an empty square or move one according to normal chess rules. Capturing only happens when moving.

The goal is to align all four of your pieces in a straight or diagonal line.
When the pawn reaches the edge of the board, it simply starts moving in the opposite direction.
Captured pieces return to their owner and can be placed again on a future turn.
