Push or c/f when pf stealing get called?

[httassadar]

Blinds are t25/50, and I'm at CO with t1200, BB is quite the same at t1130. All fold to me and I raise t300 with 98s. Called only by BB.

The flop comes K32 rainbow. BB checks to me. The pot is now 625 and we both have about 900. If I cbet about 300 and get called, then I'm committed. So the choice is push or c/f. What shall I do here?

That hand was checked down to the end, and BB shows K7o and takes the pot.
