These are tough, first off I don't think I'd be raising this trying to get it heads up when I'm in early position. This is a speculative hand from early postion and should be played like one.

If this guy will call with middle pair but not bet it, why not slow down on the turn card and see how he reacts to a card that probably didn't help him. He can be pretty sure that the duece didn't help a pre-flop raiser.
