About 48 tables remain in the Event Center and about 13 tables remain in the poker room, meaning fewer than 610 players are still in the hunt. Those players have been sent on a one hour dinner break. Play will resume at 8:30pm.
Isok Aronov
Before the break, I did an entirely un-scientific survey of the tournament floor and believe that Isok Aronov (Brooklyn, NY) is the chip leader. He's sitting behind about 250k. Matt 'muffins' Mazzeo (E Williston, NY) is close behind with ~240k.
No idea what the stacks look like down in the poker room, so no way to be certain about the chip lead.
