JK in the BB...I want the pot!

[johnnycakes]

I've been trying to work on my postflop play. My W$WSF is very low over a significant sample.
I'm sure it's 'cause I don't make enough moves when I miss the flop in general.
So...How's this:

1/2
Villain who strikes me as nittish opens for $7 in MP.
I call w/ JKo in BB.

FLOP: 8 9 6 r
I check. He bets $11. I raise to $33. He calls.

TURN: T
I fire $48.

How am I doing so far?
Bad flop for a C/R?
C/R to more than $33?
Fire more on turn? I didn't think firing more on turn was necessary with the draw hitting.

Thx.
