So one player is all in for the main with callers. There is additional action to build a side pot. One of the players for the side pot has the winning hand and all the players discard their hands. The side pot winner wants to see the hand of the player all in for the main pot (just for information, not for anything related to collusion). Does the player all in for the main have to show or have his hand revealed?

Depends on whether the house rules allow IWTSTH requests. Historically most rooms have allowed them (though if the winner makes the request, then the hand is live). More recently, more and more rooms have been disallowing the request, though I would say the majority still allow it.

TDA rules would make it a floor decision.

If it is a tournament, I believe since he is all in, he must show his hand.

I'm under the impression that if this is tournament play, then he must show his hand.

Yes and that’s a frequent point of controversy IME. For some odd reason, players feel like they get punished twice. First, since they were all-in for the main pot, they are eliminated from the tournament and then they are forced to also show down their bluff or whatever they don’t want to show. At that point there’s also the mindset of “I’m out, you can’t tell me what to do anymore” followed by a dealer who uses his arm to block the muck..

In cash games, I have no idea what percentage of rooms still allow for IWTSTH for information but the last time I’ve seen a player ask for it, the floor came over and told him that they usually don’t do that.

That is true, but I included that info because many rooms are now using TDA rule for their cash games. But I don't think they require showing in this circumstance. I may be wrong though.

I would say that in the card rooms that I play, the player would have to show his hand and would be eligible to win the main pot if he accidentally mucked the winning hand since the person winning the pot asked to see it.

Forgot to mention this is cash since everywhere in Vegas, you have to show when there's an all in with a caller and no additional action (or at showdown).

You have to show in tournament because the elimination of a player impacts the entire tournament field, not a singular cash table. And yes, I can name a handful of times a player has tried to muck a winning all-in hand and one time it was a chop. A player being eliminated and another player having all of their chips is something tournaments should definitely continue to avoid. All hands being shown helps reduce that occurrence.

1) Any tournament all-ins are shown to eliminate possible chip dumping. In one room they require even the 'losing' hand of the side pot to be shown since there was an all-in involved ... basically for the same reason, chip dumping. So basically you can't voluntarily muck a live hand at Showdown when there's an all-in involved.

2) Surprised that a Player 'has' to show his hand (when all-in) in cash for any reasons other than by request or to claim a pot. If Vegas has had issues with chip dumping then that's one way to limit it for sure.

You certainly have the issue of 'who' is requesting to see the hand. Typically a Player who has a claim to a pot risks losing that pot if they request that a hand be shown/tabled, otherwise the hand is considered dead even though it's not in the muck. GL

I would agree with this.

As for tournaments, all hands at showdown would have to be shown if they called all bets in the side pot because they also called the all in. A lot of dealers miss this part and don't make everyone show even though they should. Most often, no one notices and no one is the wiser so it makes zero difference, but it is the rule for the rules Nazis out here.

That rule makes total sense when I read it here but I can’t come up with a single instance where I witnessed a dealer telling a player they had to show their hand when they mucked to the side pot winner.

Me either. Suit, can you cite a rule or sub-rule on this? It makes sense but then it doesn't because there's still action between the side-pot players. The all-in player isn't turning his cards over until after the side pot is awarded. Weird situation that I've never thought about before.

The TDA rules explicitly say that all hands are turned up if there is a side pot once action completes.

You would see it at my place. I bet I'm in the minority tho.


Well there you go... Thanks dinesh

You will see it at all casinos that host a MSPT or HPT event ... and probably most if not all that host WSOPc events. I've seen it in person and on streams both.

This rule is 'obviously' waived in cash games correctly IMO .. GL
