A very gray area. I hear people always say that poker is a Gentleman's game. What is the difference between seeing one of his cards if the dealer mistakenly flashes it when dealing it? Or what if someone mucks their cards and mistakenly flashes one of them and you're the only one still in the hand who saw it?

So if playing online and someone is stupid enough to install a trojan horse program from an Email I send them that installs a program that allows me to see their cards, is that not cheating?

If you can see someone's cards, then I don't see anyway how that can not be considered cheating.

Poker Tells on the other hand are part of the game.

A key element for me is whether I set up the situation ( like the trojan or marking the cards etc) or whether the knowledge gained was inadvertant. I'm a bit biased because I not only play professionally but also for my own pleasure and it spoils my pleasure when people show me their cards.
DS's example is nice because it does fall right on the line for me although I can respect others that have opinions on either side.

In bridge I would definitely tell them to hold their cards back and I wouldn't take advantage if they didn't.
