April 9, Sunday night at 8-9pm EDT on GSN. It's part of their "Anything to Win" series. Other subjects include Johnnie Cochrane and Arnold Schwarzenegger.

While few question the destructive and self-destructive energies of Bobby Fischer, the balance among immaturity, tactless honesty, declining mental stability, and crafty psychology can never be known for sure.

I'd never heard of this channel or its previous incarnation "The Game Show Network." It's channel 117 on my NY cable and I've set my DVR to "stun." They have a channel finder here.
