The Cthulhu Master Tournament has been running at Gen Con since 1989. The CMT runs for three rounds, with 3 players advancing from each initial session to a predetermined 2nd round slot. Be sure to sign up for the first round session that corresponds to a second round slot you can play in, if you wish to advance. Maybe you will win this year's MiGo Braincase trophy and become a Cthulhu Master. Sign up on the first day of registration to get in!
