I think you quit one raise too early in the first two and played a bit too fancy in the last.

The way you played it, I dont mind just calling down when he 3bets your check-raise as you have shown alot of strenght and you aren´t likely to get reraised by 2-pair given the scariness of the board.

Btw, you aren´t going to lose the "TAG" button very often as he will be drawing or have slowplayed the flop most of the time and probably wont fold for one more.

I´d say MP has some king or JT mostly, but ofcourse AA/AK/KK/QQ sometimes aswell. It´s just a bit weird to slowplay on a board this cordinated.

The second hand seem close as you lose 2 more when behind and just gain one alot of the time.
He is 2:1 to hold AJ/99 vs AA if you think he plays them the same. I think the first two should be discounted more, mostly based on preflop, however, he will sometimes overplay the river or show up with an unexpected hand like 77, A7 etc, which I think will turn this to a raise.
