Villain was pretty passive and called cbet quite often. No strong reads.

Fold. Another nuts probably (fh, straight, trips, maybe some dumb J), if he had 7 he was probably too scared to fold you out of the pot with raise so he is trying to make up for it now.

Why did you bet turn?

edit: see below, ignore above.

I'd definitely bet the turn but bet smaller. I'd fold in this spot pretty much 100% vs. this type of player.

crap. i somehow missed that i'm in the HU forum.

looks like a pretty easy fold vs a passive

I think you know the answer to this one. Is he valuebetting worse? No. Is he bluffing 35% of the time?

I'd fold AJ.

edit: which means i'd fold AA too obv.

against this type of player, which is probably the most common player type at these stakes, you can pretty much raise 100% on the BTN and value bet super thin and just fold everything short of the nuts when they raise you (or adjust when they start to get annoyed).
