villain is 23/13/2.6 (89 Hands)

The reason I flat PF with AA this hand is cause the villains behind me, and the table in general, was playing very very aggressive PF, more aggro than normal.

The BTN and blinds were 3-betting, squeezing, etc.. very frequently.

$2/$4 No Limit Hold'em - 7 players

MP: $223.30
Hero (CO): $544.50
BTN: $194.70
SB: $86.00
BB: $485.00
UTG: $386.00
UTG+1: $429.30

Pre Flop: ($6.00) Hero is CO with A A
1 fold, UTG+1 raises to $12, 1 fold, Hero calls $12, 3 folds

Flop: ($30.00) 9 6 J (2 players)
UTG+1 bets $20, Hero calls $20

Turn: ($70.00) 7 (2 players)
UTG+1 bets $48, Hero calls $48

River: ($166.00) K (2 players)
UTG+1 bets $96, Hero calls $96

Is calling this standard or too spewy.

Although villain could barrell the K, trying to rep it it hits me a lot as well I think. KT, KdXd, QT.

TT, JT other 2 pr hands are also in my range.

Villain would probably c/call the river with 1pr hands, right?

Look forward to your valued comments and input.
