One thing I like about George Thomas courses is that some of them have the second hole return to the clubhouse, one benefit of which is keeping extra hole matches close to the clubhouse.
I think matches go to extra holes if it's an individual competition - the US and British Amateurs, the Accenture Match Play, your club championship - but not in team competitions - the Walker, Ryder, Buda and Dixie Cups - where a half point adds to the team totals.
