Another edition of "You be the floor"

[RegBarclay]

First let me say that at my casino we have a rule that players may not show their cards to anyone who was dealt in for the current hand. If they do so they are limited to passive play only (meaning they can only check and call but no longer bet or raise).
This rule does not apply here as according to the OP he showed the hand to his friend after the all in bet, but I think it is a good rule to have and since enforcing it there have been far less calls for the floor.

Another rule of ours is that a player who opens his cards when facing a bet or raise may have his hand ruled dead. Up until today I have always ruled a hand dead if it was a pot or no limit game and the player was facing a large bet. So this would be the point where the hand ends for me (if I am called to the table at that moment).

As it went down I would award the pot to the quads and give the player who miscalled the hand during play a strong warning and remove him from this game. The regular who showed his cards will have a private talk with me during which I explain to him how lucky he got and warn him never to show his cards during play again. The player who opened his cards will not get warned never to do it again as at this point he is probaly calling me all sorts of names and being escorted out by security.
