You have to show all your cards at an actual showdown, don't you? Or can you do this if P2 mucks without contest if the shown cards are enough?

Obviously your opponent no longer has cards you don't have to show yours. However that is subject to a player invoking the IWTSH or show one card show both rules if the room has those rules.

I suppose this may be back to the etiquette rules rather than the actual rules; do you consider asking to see a full hand at showdown the same breach of etiquette as asking to see a winner that did not require showdown? If I were P2 in this situation (or anyone at the table), I would expect to see a full hand because the information *was* paid for, regardless of whether or not the shown card was enough to take down the pot.

I know the first time I played O8 in a card room, I was asked (by the dealer) to table all four cards even though I knew I was only playing for half the pot. I thought this was standard but wasn't totally sure.
