Campbell Check-Raises Arzoomanian
Level 19
: 5,000/10,000, 1,000 ante
Robert Campbell was first to act in the small blind and he decided to complete the small blind instead of raising. Paren Arzoomanian, in the big blind, raised to 25,000 and was called by Campbell.
Campbell then checked the 
flop, opening the door for Arzoomanian to bet 25,000 chips, but no sooner had he done that, Campbell check-raised to 75,000. Arzoomanian looked at how many chips Campbell had behind before seind his cards into the muck.
