should i have been thinking he's got power cards since he met my PF raise? like A 10s or something?
As I am seeing it, (and I also play on PS ) You right there. Alot of the SnG's I have played in alot esp at lower buy in, are playing tight poker. If he had be agressive on the Flop I would have thought Missed Ax, or Straight maybe. The Turn bet is "safe" as I see it. 2xBB is pretty small and a straight chaser I could see going after it. I think it was safe not to reraise on river for the simple fact that since there was no straight flush out, he might be slow playing the set.

My little 2 cents worth
