Commonly played by drunken fraternity boys in the mid eighties, extreme chess has only become mainstream in the last 2-3 years. Every time you take an opponents piece, you are allowed one closed fisted hit anywhere on that opponents face, while remaining seated. Players must always alternate striking hands, and achieving a "check" allows for two blows. God forbid you shoule be worked into "check mate", because that attracts the afformentioned double blow, however from a standing position to inflict maximum degradation.
After having a few drinks with the lads..."Hey guys, lets have a game of extreme chess!!"....."Fuck that man, I'm not that drunk, lets play Russian Roulette instead"
