QQ's UTG facing a reraise.....

[tiger7210]

Early in $50 MTT on UB

No significant reads and only hand i have shown down were a pair of 99's.

Blinds 10/20

I pick up QQ's UTG and raise to 80 (1970TC)
folds to CO who reraises to 270 (1550TC)

what line do you take here PF?
Push or flat call?

Neither I'm thrilled about without any type of read.
