Daniel Negreanu had yet another impressive session in his grudge match against Doug Polk, and extended his lead even further.

Thursday’s session was quite competitive and there weren’t many massive pots. Early in the match, the poker pros traded jabs, with one player winning a sizable pot and then shortly after the other returned the favor.

For Polk, although he didn’t turn a profit, he found some more success with his over-sized river bets than on Monday. During that infamous Monday session in which Negreanu booked a $222,000 win, Polk lost most of his money due to some ill-timed big bluffs. That wasn’t the case so much on Day 8 and it led to a much smaller defeat.
