I was running a fundraiser 2 weeks ago and this situation came up. I was acting as TD, working the room, I get called over to help with an all in situation to help calculate side pots.
I didn't do the math, I just matched stacks to make the piles, the hand plays out and I leave. Pocket 7's wins with a set. Cards get tossed to the person who's about to shuffle across the table and then one of the cards tossed to him is from the wrong deck. The person who won the pot, who was holding pocket 7's, had 2 different color cards which nobody noticed. The chips have already been pushed into his stack, people don't remember how much was bet by whom since there was several players by the turn but heads up by the river.
What's the ruling?
