Villain had a PFR of 86% (2bb) and 14% +2bb
Aggro, and saw him bluffing before.

PF I see a really strong range, made mostly by AT+ (maybe some A8, A9). KJs+, KQo, 88+
Choose to call carefully.

When he X flop I keep all this range that could be slowplaying or seeking for 2 streets value (88+)

When he bets half pot on this turn I think his AT+ would be betting larger (3bb+) to protect vs FDs and get value from T's and AX that i could have.
With the half pot I keep mostly KK-JJ and KJhh+.

The 3/4 river seens even more as (1) bluff, (2) this pocket pairs that thought my Ax would be raised Turn.
Here i got a little greedy
And tryed to extract more values vs this hands.

What do you think about that read, that line I took, that miniraise, aaaand...

What combo do you think villain got there?
I doubt you can get it right!!!

Posting the result later.

I prefer a blocking bet to river, to not check the river
