What is Giveaway chess?
In Giveaway chess (also known as Losing chess, Loser's chess, or Anti-chess) the first person to lose all their pieces is the winner!
The king is just another piece in Giveaway chess, there is no check or checkmate, and losing the king does not end the game. You must lose ALL your pieces!
Captures are compulsory! If you CAN capture, you MUST capture, though you may be able to choose between different ways to capture!
Stalemate is a win for the stalemated player! If you can't make a legal move on your turn, you win!
No castling!
Pawns can also promote to a king!
