I rarely use stop and gos...good time for it?

20+2 at Stars, close to 700 started. Down to final 11. Blinds are 4k/8k with 300 ante. I'm in 9th.

2 folds, good taggish player opens for 24k, folds to me in the BB w/44, I have 78k before posting the BB, he has me covered. I call here. His read on me at the moment is probably that I don't defend my BB enough and am pretty tight.

Flop is 882r
I push for ~54k....good stuff?
