Hello! Here is the scenario: (this was not on a tournament table, but a 1-3 no limit game)
Players are on the turn.
Player A pushes all in for $400.
Player B folds.
Player C does not announce anything, but just flips his A 10 of spades over.
The dealer burns and deals out the river card, giving player C the nut flush.
Player A says his hand should be dead, since he never announced call. The dealer ignores him and pushes the pot to player C. Player C racks up the chips and cashes out. The dealer never called the floor over to handle the situation.
Are player C's cards dead or are they live?
