It's Totally Illegal
Action was picked up with all of Josh Arieh's chips worth 25,000 in the middle of the table and Daniel Negreanu making the call. Negreanu immediately tabled his hand while Arieh hung on to his.
The dealer urged Arieh to show but he responded by telling the dealer to continue on. The dealer flopped 9♣J♥5♥ prompting Negreanu to say, "It's totally illegal what you're doing." Arieh replied, "It doesn't matter." And waited for the turn 8♠ to drop before tabling his hand.
Joshua Arieh: A♥J♣
Daniel Negreanu: A♣K♦`
Arieh was ahead with top pair which made Negreanu complain that he was aware he was ahead and still didn't show his hand. The dealer completed the board with 6♥ then pushed the pot towards Arieh's direction. To Arieh's irritation, the floor arrived, at that point, to move him to another table.
