Chulhan Choi has taken over the chip lead following a pot with day 2 chip leader Bradley Rogoff.
Choi raised to 600,000 from the hijack and Rogoff defended his big blind.
Rogoff then check-called a 400,000 chip bet from Choi on a flop.
Rogoff checked again on the turn, and Choi ramped up the pressure with a one million chip bet. Rogoff folded, sending a pot to Choi that brings him to eight million.
