I remember TIffany Michelle in last years'
wsop Main Event complaining to a guy who took 20 seconds every time it was his turn to move. Even the easy folds. That would drive me crazy too.
Taking time when you have a hand you might play is fine. But doing it every time to disguise whether or not his hand was good is lame. Folding
tells us your hand was poor, betting tells us it is good. So sure, take the same amount of time to bet when you actually have to consider a situation, but otherwise insta-muck the trash.
Exceptions to this would be if you are trying toget into the money in a tournament.
So yes, "needlessly stalling the action" is bad etiquette. People are there to play poker, and the longer you take the fewer
hands they get to participate in.
