Tell Me How Bad I Played This

[BigDRock]

20+2 tourny at Stars 650 started, about 100 left, 63 pay, I'm in abot 30th with T11,500. Blinds are 200/400 with a 50 ante.

I had just moved to a new table after playing quite well and had a good image at another table. I had a a run of about 2 or 3 hands where I was dealt good cards ad picked up the blinds with a 3x BB raise.

I am in Late Mid position with JJ, I make a 3X Bb raise and the SB and the BB call. Flop come 689 rain bow and I bet about 2400. SB folds and the Big Blind raises the min. I move all in for 5000 more and the Bb calls and turns up T7 for the str8. Im out in 95th.

How should I have played this here. Should I have bet more on the flop or should I have floped to the Bb's reraise. I basicly thought the BB was trying to push me off the hand becuase I had been raising the previous hands and thought I was bluffing. Whats was the best plan to attck this hand or could it not have been avoided.
