Hi all.
Would like to know how you would have played this hand mainly on the turn, but other advice also welcome.
Starting stack of the event was 3000 chips, we're at 3rd level (blinds 50/100). I got 2150 chips left.
Villain is a japanese girl that had an outstanding run of cards early on (AA twice, QQ, and a lucky K on the river to chop the pot when she had KJ vs my KQ

). She's got a big stack and became quite active because of that. She had clearly opened up her range from simply being tight earlier on.
I've been playing tight pretty much the whole time, altho I did get involve with her twice earlier on pots for more than 1000 chips, because she was opeining up her range.
I'm in the hijack seat with AJo. Folded to me and I raise to 250. BB (japanese girl) calls. we're heads up. Pot 550
Flop (550): AJ5 with 2 diamonds.
Action: She checks I bet 325, she calls.
Turn (1100): Q (not diamond)
Action: She bets into me 600. Pot is 1700, I got about 1600 left.
What would you do?
Thx.
