Cowboys is a variant of the territorial game Amazons.
 
The White-hats and the Black-hats are having a gunfight. Each turn consists of two parts, and both parts are mandatory. First, a Cowboy must ride his horse, moving a piece like a Chess Knight. Then, the Cowboy who just moved uses his pistol to shoot a Bullethole into the board. The Bullethole must be exactly a Knight's move away from its present position. This will not only limit his opponent's moves, but also his own. Once a space has been shot with a Bullethole it can not be landed on for the remainder of the game.
 
There are no captures.
The first player that cannot finish his turn, looses.
