On the river with a board of J 7 4 3 7, seat 7 bet 16k. Tom Arrigoni (Edison, NJ) gave it some thought, then made the call. His opponent insta-mucked his hand. Tom showed J4 for Jacks-up to take the pot.
He's now up to ~270k and the chip leader in the Signature Room. Not sure how he stacks up against the tables still in the Poker Room.
