My thoughts: he prob has me beat. Could he have KK/AA? maybe but not likely. QQ maybe, 99 is what I think he has, of course 44 is a possibility. Would he try to protect on the flop? Maybe but my image was very loose/aggressive, so maybe not. He would likely bet 44 on the turn, he would def. bet KQ/AQ on the turn and not insanely push the river. Those are my random thoughts when I was playing. Opinions?

i never fold this.

This is pretty obvious, but atleast give some reasoning because it isnt obvious to the OP.

His stats are incredibly tight and overa decent sample, but to put a guy on quads is really trying to find monsters under the bed. You hit your dream card on the river and want all the money in.

Im not really sure why the push on the river is so insane, given stack sizes, if you are raising it should be a push.

What could he have here? Honestly, Im not that sure, but I wouldnt be surprised to see a random 9, a big Q or even KK or AA. This is a profitable call and one you need to make.
