We always pass the deal around...did nobody think it was odd he was so lucky when he was the dealer???? Should have been super obvious very early. Its harder to catch when they throwing the win to a partner. Be vigilant and it is hard to cheat u, pay attention-if the cards go out of your sight, set the person straight and re-cut. It is shocking what you can get away with when people are in a 'friendly' game and or drinking...we would jokingly trade cards before folding, nobody said a word, could have played them. If someone got caught cheating for real in one of our games, it would be VERY ugly, ass kicking ugly, friend or no friend.
As a rule I will not play real money
with anyone who I even suspect is a mechanic, just mind boggling what those guys can do with cards, even when u know they are doing it.
