Opponent is a very aggressive and tricky but solid player. My image is very loose but I only showed down good hands...

I call here, think about what fullhouses he could have. Both QQ and KK are extremely unlikely because they would raise at some point in this hand, especially if villain is aggressive. Quads? Probably not. 33 wouldn't stick around to the river unless this guy is a huge idiot. I don't know what to make of this hand actually. No hand raises the river that we beat assuming villain is competent, i.e. KQ, KJ, A9, AK, etc. They all either fold or call. So I guess the only thing we're beating at that point are bluffs. Well, maybe a slowplayed AA that likes his two pair. I call and pay him off if he's got something bizarre like K9.

I actually think he could show up with something daft like QJ here.

It is very read dependent. Would he call the flop with T9? Given that he is aggressive would he raise the turn with trips?

I probably call, but I'm a POW.

I made the same reasoning about his hand as you both did. And I made the crying call. I really hated it. But puuh. He showed his AA.
