Negreanu's Check-Raise Fails
Level 22
: 20,000/40,000, 40,000 ante
Jason Koon was dealt a suited ace once again and he raised the 
to 90,000. Daniel Negreanu called from the big blind.
The 
flop didn't seem to be action-provoking at first sight. However, Negreanu opted to check-raise Koon's bet of 60,000, making it 200,000. Koon called with the backdoors.
The 
saw Negreanu checked and Koon, who spiked a flush draw, took down the pot with a 215,000-bet.
