Play What You Know; Know What You Play

I wonder if White's opponent in the following game expected to catch him by surprise by playing a wild counter gambit? If so, then perhaps he was taken aback by the "Jerome treatment" of the opening. We have seen this kind of thing before. As the notes show, Bill Wall plays what he knows.
