From my own personal experience, not long after I started playing poker...I committed the cardinal sin of calling another person's hand (in a low limit 2/4 game) when a player did the same flash thing thinking he lost the hand (he was sitting right next to me).

Needless to say, the guy that he now beat told me if this was a higher limit game, I may have gotten killed.

After that I have probably seen dozens of hands folded that would have either split or won and I don't say a word.

Interestingly, about 2 weeks ago I saw a guy fold about a $1000+ split pot in 40/80 when he called with A5s after ATo bet into him on the river and he just called. Board was AKJ4A, the guy looked at the other player's ATo and mucked. I just walked away astonished.

Lesson learned, if you aren't involved...let it go. Cards speak for themselves, but a player must turn them over and let the dealer call it...not another player.

That's just my .02
