Every fifth move, both players can move any pawn one square, in any direction.
What strange chess rules can you think up?
Falcon Punch: Once during each game, you may punch your opponent in the nose as hard as you want. If he bleeds on a piece, it is removed from the board. If he gets knocked out, you win the game and his wallet.
Cannibalism: You may remove one of your own pawns that within one square of your knight. The knight then upgrades from a {1,2} leaper to a {3,4} leaper for this turn.
Conversion chamber: Before the game begins, each player writes down a column letter (A through H), which they do not reveal until necessary. If an opponent's pawn promotes on the column you've chosen, the promoted piece becomes your color, not the opponent's.
And if both players choose the same colur??

Iron the Killer's idea is for every blunder you make,your butcher knife is stolen from you for killing people.

If playing on a Saturday the losing player MUST let the winner DATE his wife for 1 hour. However, if a rematch is accepted and the same player loses again, the winner (of both games) gets his wife for a year. But only on Saturday.

If you play a stupid move, then at least 3 spectators are obliged to stand next to your table and point at you for five minutes.

Date for an hour? How about 5 minutes in a closet?
Sounds like spin the bottle.

Maybe hardcore spin the bottle, lol.

Now, now, boys ...... really? Isn't Chess known as the "Sport of Kings?"
Is the noble game of chess not rightly viewed as a worthy pastime for cultured, refined gentlemen and ladies of intellect, polish, grace, and erudition? Surely we can do better than this ......
(And again, as always, I apologize for having called any of you "Surely.")

Cool, thanks and for not calling me Lavern also! I hope people get this reference as well!

I would like to be able to create a merlin piece that you can select when you get a pawn to the end of the board. It would have the moves of a queen but also a knight
The rule that you are not allowed to capture a king grounds the concept of checkmate upon illegal possibilities.
