This hand happened in a home game but im trying to run this game like a casino so i guess im asking what would the ruling be in a casino.
1$-2$ plo game, 3 players see the flop with player A being All In for around 170$.
Flop comes, player B bets player C calls.
Turn comes, player B check calls All In and they have a side pot of around 1000$.
Player B says twice, player C says ok twice.
Dealer says twice, taps the table with his hand and opens twice.
After he opens player A who was All in for the main pot says "wait why didnt you ask me if i wanna go once or twice" and opens Nut flush which is the nuts for the first opening.
So player C won the side pot and wants half of the main pot, and player A says he deserves the whole main pot since he wasnt asked and would have said once.
Now what?
