We've seen 2013 WSOP champ Ryan Riess steadily chip up here on Day 1a, and one of the tools he's using to do it is the good old check-raise.
In a recent hand, the under-the-gun player opened for 1,000 and Russia's Roman Korenev called from the small blind. Riess came along from the big and then both blinds checked the flop.
The original raiser continued for 1,700, Korenev called, and that is when Riess check-raised to 7,000. That did the trick as both his opponents folded.
