10-25 NL in new orleans

[The Truth]

Here is a hand I played tonight. I'm new to the table. SB is a middle aged fella, who comes off as a donk, but no real read, so I played it as though I had no strong read.
I've only played 10-25 no limit a few other times live, and im up pretty good so far at this level. I'm over bankrolled for the limit, but still cutting my teeth.
For the weekend I am up 700 or so playing 20-40 and lower NL. Ive bought into 2 tourneys for 200 and 500 so im dead even going into this hand.

I am in mp2 with 2500 in chips. 10 handed. 10-25 nl holdem.

2 limpers to me, I have J9 of diamonds.
I limp, co (1500) limps, button(3500) limps, sb(2300) completes, bb(3000) checks.

Flop comes 10h Qd Kh

check to me, I bet 100. Folds to button who calls, sb raises 400 more to 500, everone folds to me. I raise it 1000 more to make it 1500 straight.

thoughts so far?
