I wasn't on my comp when i played this hand, so no HUD. I've played probably 50 hands with the villain so far and he seems pretty good and decently aggressive. I haven't seen him showdown a bluff or anything retarded.

Knowing that this guy is a TAGG and solid, i thought there was a good chance that he thought the Q was a good two barrel card for me. Also, he took about 10-15 seconds before shoving the river.

Obviously, this is a marginal situation. I doubt he shows up with AQ here, KQ possibly but not likely for a lot of reasons. I feel like my hand is really nothing but a bluff catcher. But, i also think that he's bluffing here about 15%-25% of the time (my best guess). So pretty much i answered my own question that the river is a fold, but i'd like to hear if your analysis is any different.
