Right, 1st session since moving up, at 10NL I would pretty much play AJs on the button the vast majority of the time for a 4BB raise, unless it was from a 4/4 type nit. Anyways, stats on villain, playing 19/17 only over small sample (60 hands). Only other hand that I could see was him opening KJ from cutoff, flopping top pair (K) betting flop, checking turn, checking river, so seemed pretty straight forwards. So here it is:

Poker Stars $0.10/$0.25 No Limit Hold'em - 6 players

BTN: $36.40
SB: $25.00
BB: $22.25
UTG: $25.00
MP: $25.00
Hero (CO): $31.05

Pre Flop: ($0.35) Hero is CO with A J
UTG raises to $1, 1 fold, Hero calls $1, 2 folds, BB calls $0.75

Haven't got much on him so assumed by the hand I observed he played pretty straightforward, so pockets with AK/AQ maybe AJs thrown in there. Is this pretty standard for this type at 25NL or does it need some adjusting?

Flop: ($3.10) A A 8 (3 players)
BB checks, UTG bets $2, Hero calls $2, BB folds

Turn: ($7.10) 8 (2 players)
UTG bets $4.50, Hero calls $4.50

River: ($16.10) K (2 players)
UTG bets $17.50 all in, Hero calls $17.50

Will post thoughts when I get back.

i dont think calling down is super bad here, but i would raise the turn. Either way cooler since he had AK

i call it down, but ur toast on the river imo,no way hes shoving anythin u bet
