Did He Have Quad Aces?

With around 400,000 already in the pot and a board reading , Rogen Chhabra, who was in the big blind, check-called a bet of 80,000 from Joseph Hebert. When the river put three aces on the board, Chhabra seized the initiative and led out for 160,000. Hebert thought for a minute before putting in a raise to 520,000, and it was enough to get the job done as Chhabra released his hand.
