Initial setup

Gold general: moves and captures to adjacent squares in any orthogonal or the forward diagonal direction.

Silver general: moves and captures to adjacent squares in any diagonal or the forward orthogonal direction.

Pawn : The Pawn: moves and captures to the square directly in front of it.

Promotion

Drops

Captured pieces become prisoners and lose their promotion, guarded on your right. You can use your turn to put them back into play. A player can either move one of his pieces or drop a prisoner back into play on his behalf.

A pawn can't make an immediate checkmate when dropped. It is allowed for other pieces.

A piece can't be dropped is no subsequent move is possible, so a pawn cannot be dropped on the last line.
