This is an interesting discussion. What I have learned most is that you all suck at making analogies.
Seriously though, while live poker and internet poker are different beast entirely, there is a direct comparison that no one has mentioned yet. Back in the WSOP a couple of years ago there was a famous hand between Howard Lederer and somebody else. The hand had lots of action and the nameless one shoves (on the river I think) and then pulls his shirt over his head. Everyone laughs, but the guy stays that way until Lederer folds. As I remember fuckface’s hiding was not considered unethical, and I would think that hiding during a major hand in a live game a farther deviation from the spirit of the game than using a different account on the internet.
