Not that exact setup but.....one of my live game regulars had an adopted son that was mentally challenged. His basic math skills were fine and he understood hand rankings and after watching many weeks he was allowed to play. His game was all over the board, a real 'any two cards' to a raise player, but over the course of 2 months, he cashed as often as the average player, winning once. His sheer unpredictability gave him a huge fear factor, as he might call any shortstack shove with ATC, and then play pocket aces brilliantly followed by donking off half his chips. You just never knew whether he had nuts or total junk. In the long run he was dead money but he hammered some good players in his time, sadly leading to the classic 'gamblers memory'.....he always played on the "i can win" theory as opposed to good solid play and blew his monthly allowance regularly. (He was over 21 and had a managed fund allocated to him by a trustee.). He was a really likeable kid and it took a bunch of us verbally ganging up on him to get him to stop throwing his money away, but every now and again he plays one tourney......and you're still afraid of him calling!!!!
