hand vs ggbman

[Chris Daddy Cool]

25/50 3 handed on eurobet i have 8k, he has me covered.

me and gabe have a history with each other. he thinks i'm a lot better than i actually am, though i did bluff him on multiple hands with him folding the winner where he responded with "F*ck you"

given our history i feel my flop and turn line is correct here. i can create some action with him but i can't overdo it or i am pretty confident he folds most hands.

i limp with K [img]/images/graemlins/club.gif[/img]K [img]/images/graemlins/diamond.gif[/img] in the SB. He makes it 200 in the BB. I call. 400 in the pot.

Flop: 9 [img]/images/graemlins/club.gif[/img]3 [img]/images/graemlins/diamond.gif[/img]2 [img]/images/graemlins/club.gif[/img]

I lead out for 300. He makes it 1000. I call. 2400 in the pot.

Turn: 6 [img]/images/graemlins/diamond.gif[/img]

I lead out for 1500. He calls. (In retrospect, I feel I should bet more here.)

What is my best line?
