In order to become even *more* of a rules nazi I do check to make sure if I handle irregularities correctly. Recently there were two incidents which came up where I inadvertently used the wrong procedure.
* Wrong colored card - there was a gold card which showed up in one of the other decks at WNP. Having a card from another deck is one of the few instances where a hand is invalidated. At the time the card showed up (it happened to be pre-flop, during the deal) I don't even think there had been any action yet. If any money had been put into the pot then all bets should be returned. What I did was to replace it with the card below it which is incorrect procedure for that case. Speaking of which...
* Boxed (face up) card - a face up card was dealt as one of a player's hole cards. Correct procedure here is to treat the card as a "meaningless scrap of paper" and to deal the card below it to the person who was dealt the boxed card. I had used this procedure to address the wrong colored card above. What I did was treat the face up card as a face down card which had been exposed by the dealer so I completed the deal, gave the person with the boxed card the burn card, and used the face up card as the burn.
I apologize for the errors. But following up on irregularities helps me to make sure that they are handled properly if/when they come up again. By the way, once the hand is complete all action stands.
By the way, after the hand is complete all action stands.
