You should try Extreme Chess. The rules are mostly the same as Regular, Non-Extreme Chess, but instead of each player making one move each turn, each player rolls a d6 and whoever rolled higher makes a number of moves equal to the higher roll minus the lower roll. Black rolls 6, White rolls 3: Black moves 3 times. Black rolls 3, White rolls 1: Black moves twice. Black rolls 1, White rolls 6: White moves 5 times. A typical game lasts about two minutes, and if you get destroyed it doesn’t matter, because it only took two minutes and next time you’ll be the destroyer; it’s a *perfect* game for playing at the table at conventions, because all you need is a cheap travel chess set and a pair of dice, and novices can still compete with grand masters because of the randomness.
