either fold or call and take it away on turn.

I agree with the above quote, read dependant (I know you said you didn't know him though). It would help to know how often this lead means he's going to stay with you on the turn (would he lead w/ JJ here, and if so, would he fold to a turn raise?), or if it means 77, 88 (assuming they will go away). Your image might also help.
