I would have raised the turn too. Raymer should have folded to the turn bet. He has one pair on a dangerous board. If I was Raymer, I would have pushed pf or on the flop.

I think he played incorrectly post-flop. If he was going to be in it for long haul, he should have pushed the flop. If Raymer was scared of ace coming on turn or river, AT-AK has only 3 outs and will likely fold to a flop push.

The more I review his play, the more it doesn't make sense.
