philly, that really depends on how active he's been.

Since the op added that he's been in more pots than has seemed appropriate then, yes I'd call pre, float the flop and fold to the turn overbet shove.

If he'd been playing very few to no pots then prolly not. We've got the other shortstackers in the btn and sb to think about. A shove squeeze from one of them would be very difficult to continue against.

If he'd bet 1/3 to 2/3 pot or checked on the turn then I'd prolly try to take it from him.
