As incredible as it seems, here's an interesting link:
No Limit Bet Chess!
Thats right - <font color="red"> Chess! </font>
Basically this is chess with dice, chips, and bluffing!
You can make more than one move per turn depending on the dice, and you make a bet before you move. The other guy has to call to see the move etc.
The way you would bluff is deep in the game when if you move twice you can checkmate . You can pretend you have the dice number to give you two moves. So basically you can push your chips all in !
