That would be really bad.You will get the whole table against you, I guess
As said above, up to tournament director but typically you get a penalty for 1 rd of your table, so if 9 players you have to sit out 9 hands. And btw doesn't matter if you do it by accident even, still a penalty, though some directors will be more lenient than others, at least where I playhmm, yeah interesting. I certainly know you're not supposed to do it, but i always wondered what would the actual punishment for it be. thanks for the responses
