Grunch and using Poker Stove as always: this one is obviously very dependent on your read. If you put villian on AA, KK, JJ, TT, AKs, AK, AQs, AQ, AJs, AJ, you still have over a 20% likelihood of winning. With the pot lying 8:1, I think you have to call the turn.

Added after reading the thread: I only thought about the turn. If you check/call the flop as many others recommend, the pot is smaller on the turn and the answer might be fold then.
