WHOAH!! What do I do on this Turn ??

[quarkncover]

This hand was on Ultimate Bet a few days ago, apparently I didn't have Ultimate History on at the time and the hand history has been lost to the poker ether. Tough turn spot with no reads that left me at a loss as what to do.

Hero????

After thinking for a bit I narrowed Villain's most likely hand range to a set of 88's, flopped baby flush, AK with Kc, or maybe a weaker two pair, and I wasn't sure what to do. Is my range to narrow? What would you do here?
