A) thoughts on not 3! pre? I tend to mix up whether or not I 3! pre with AQ against an UTG raise. I think this time I decided not to because this player is relatively unknown to me.(only 55 hands)

B) As played, is river a standard call? Is it a fold? My thoughts on making river a fold is that his river sizing seems like a value bet and I don't think villain is value betting range doesnt hold many hands worse than AQ here. Only AJ comes to mind.

My thoughts on making this call is that AQ is pretty high up in my range here, I don't get to the river with this line with many better hands. I shouldnt have AK or KK as I would 3! pre with those. I could have 1010 or QJ but probably would have raised flop/turn. K10 here might be the only better hand I have here that doesn't raise on flop/turn.

Your thoughts?
