I would probably fold - he knows you have a hand and can probably put you on JJ/KK/AA and is betting for value - I doubt he would turn anything like A10 into a bluff.

However I had a similar played hand the other day where opponant took that line and I folded - he said he was betting JJ for value? so you never know
