Mark Dube
With approximately 30,000 in the middle, four players checked a 

flop.
On the
turn, Todd Breyfogle (@sharkslayerrr on twitter) bet 21,000.
Mark Dube, who was next to act, spent two minutes studying Breyfogle, before raising to 50,000.
The other two players folded, and after another minute of contemplation, Breyfogle finally released his hand.
Mark Dube - 180,000
