Live Final Three, Wrong Play?

[Rob Blackburn]

1600/800 with 200 ante

I'm in SB with 5500

Delt Q9o
Button folds, I complete blind, BB Checks.

Flop comes JT9 rainbow
I move all-in.

Is this the best route of play or should I think check/min. bet/pot bet first? I felt like I could take it down here and if not I'm not that scared of a call really, but I figured any decent player lays down just about any hand here unless they hit the straight. Is my thinking wrong?
