AK rr pot river bluff

[McBeef]

villian is lynette chan she seems ok but a little passive, her stats are like 26/20/2 and she plays ~4 tables. i dont have any real history vs her but i play like 22/18/4 usually so idk if she picked up on that. ive reraised her like once before, but that was a few days ago. ive only played a few hundred hands with her
i bluffed river because it seemed like any hand really need to protect on the turn there so she was likely weak and might find it hard to call the overbet. but of course my river bet looks bluffy cos i would usually bet this turn with a real hand

im pretty much putting her on 88-99 here, assuming shed raise the flop with AA-KK and maybe flats with QQ and probably folds stuff like AJ pf, and im quite sure shed bet QQ/TT on the turn

i was think betting turn for like $200 might be a lot better

what do you guys think of it
