Hello darkness, my old friend.
We've not seen anyone four-bet for a while on the outer table but chip leader Remi Castaignon just used to it pick up a decent pot from Jean Pierre Petroli.
Castaignon made it 160,000 from the button before Petroli slid out a three bet to 400,000. A click back from Castaignon bumped it up to 800,000 and Petroli was left with two real options, push or fold. He chose the latter and Castaignon increased the chip lead.
