There was a bit of discussion on table 2 after a hand had completed. Before we get to that, the action kicked off with Takao Shimizu raising it up double to 4800. He was called by four players. Everyone checked until the river 9♣ 5♦ K♥ Q♠ 3♦ which saw Chris Morrison bet 15k. Next to him was Anton Del Rosario with a 35k raise. The rest folded and Morrison flat-called. Morrison showed his hand A♠ Q♥ while Del Rosario tapped signaling Morrison’s hand was good and mucked his hand. This is where the discussion began and the floor was called.
With Morrison calling Del Rosario’s raise, players at the table expected to see Del Rosario expose his hole cards (open first) while Morrison, the player in the hand, didn’t ask. Del Rosario told the dealer to show his cards despite it having been mucked. He had 8♣ 8♠. The discussion on whether he had to show or not continued by the other players at the felt.
