He puts out the requisite 200,000-chip raise, and Duthie comes along to the flop.
It brings and another check from Duthie. No checking for Wolpert though; he continues to apply pressure with a bet of 280,000. Duthie cuts out the calling chips from his stack and eyes up his remaining towers. After a minute, he grabs reraising chips and makes it 880,000 total. Wolpert lets it go, and Duthie is starting to find success playing back at his opponent.
He bumps it up to his standard 200,000, and John Duthie take a bit longer to consider this time, shuffling his cards back and forth between his hands. After about 30 seconds, he quietly says, "All in." Wolpert asks for a count, then nods his head and folds.
