I am not sure I buy the local knowledge thing. It does not take much local knowledge to look at the course and see that the fairways are narrow and edged by either water or thick rough. It does not take local knowledge to know that on such a course accuracy is required. Local knowledge will not help you hit the fairway. Some American players seemed incapable of keeping the ball on the short stuff. That is not down to local knowledge. It is due to playing on tour courses which reward length rather than accuracy. The talk is that the return match will be played on a course extended to over 8000 yards with virtually no rough. That might play to the strengths of the Americans but as golfer as a Scot I am not sure that I would recognise such a place as a golf course.
