In a tournament with 9 players at the table, 4 saw the flop, bet on the flop, 1 caller, bet on the turn, called, bet on the river, raised all in for the raiser, 45% of aggressors chips. He calls the all in but waits to see the all-in's cards, she (all-in) doesn't respond so about 30 seconds later he says call again. She throws her cards into the discard pile. He then turns his cards face up and proceeds to collect the pot. She then claims that she thought he folded and demands that her cards be retrieved. She had an ace high flush with A-9 diamonds, he had Q-6 diamonds. Ace high flush was the nuts. She announced her cards to prove that they were there. Does her hand stay mucked or does it get retrieved?
