Hand 1: I fold turn, but I would probably fold flop against Vixxwater. He gets real aggressive when he plays postflop. I think he has a str8/2pair here. I think its better to find a better spot with him than TPTK if hes firing back at you.

Hand 2: I think he floated your flop bet with AK/AJ, he tried to take it down on the turn when you checked, and then hit the river.
