The occasional idiot will not be paying attention. He'll be watching TV, petting his dog, talking to his GF, spanking the monkey, and when the computer beeps he'll look at the board and go "crap, my full house is no good anymore" and hit fold.

There are quite a few post on this over at Tales of Poker. Maybe it will happen like one in a hundred times, but when it does, it is so hilarious that it outweighs the $0.35 extra he would have won by far.

(plugging his own poker tale: http://www.flopturnriver.com/phpBB2/...oker-32875.htm). I laughed so hard I woke my little brother who was sleeping in the next room.

I guess someone should write a HUD that flashes red and has a loud voice saying "WARNING! The NUTS are on the BOARD".
