AA line check

Villain was 31/0/1 over three orbits. Due to his stats and the relatively friendly board, I called the turn push thinking he very likely had TPGK. How's my line?

I think ur beat.
This is how sets are played on those stakes.

30 hands really doesnt mean much, it shows he is fairly passive though. If you are trusting your read so much then why call a push from a passive player after a PFR, a 3/4 flop bet and 2/3 turn bet? Remember, he is passive. Is this a hard hand to lay down, yea, nobody really enjoys folding AA, but from a passive player we arent going to be ahead enough here.

I don't trust 30 hands too much either, and would disregard the post flop aggression number for that sample size, but I would much rather call a push from someone showing something like 31/20 then 31/0. These stats combined with his line against your significant aggression make me lean toward a fold, but without them I would call because 25nl has a lot of people that overplay mediocre hands. Before the call looks good to me though.

Edit..actually I would fold without a read too. Dislexic is right, most 25nl players call the turn with a hand you're beating.
