Jason Koon was really upping the pressure after he took the lead, and had Simeon Naydenov down to a little more than 300,000 before another big one.
Koon raised to 52,000 and Naydenov called to see a flop.
Naydenov check-raised all-in after Koon continued for 100,000. Koon was committed and called.
Koon: for top pair, overs, and backdoor flush draw.
Naydenov: for two-pair.
The board ran out . Koon picked up the flush draw but his opponent filled up on the river.
