You said he was a decent player, so he probably did not call the preflop raise with 52, 54, or 57, thus full house is very unlikely. Maybe A5 suited or something, or perhaps made a smaller straight. I vote reraise.

I also like folding preflop. Low suited one gap? And if you are going to play, why would you try to isolate with what could only be a drawing hand?
