Some posters on David Sklansky's message board were critical of how he played the hand he busted out of the recent World Poker Tour episode on. The tournament was down to the final three players and Sklansky was the short stack (I believe he had about 20 big blinds left). He raised with pocket fives, was reraised, and went all in. Some posters felt he should have folded his fives. Sklansky responded:
The slight saving... didn't make up, in my mind, for the public relations catastrophe of being seen throwing away the best hand... with the tournament on the line.
Sklansky also responded to someone's suggestion that he make a stop-and-go play, saying:
Like I'm going to use a play that gains maybe one percent, that neither the viewers nor the announcers understand and has a good chance of looking ridiculous.
I've certainly read speculation that people play differently when they're on TV, in particular not wanting to look bad. Since Sklansky makes more money from book sales (I'm guessing) than playing poker he may have additional motivation to play differently when on TV.
