I'm off to bed, so you two can battle it out.
Sean's rules for Sunningdale are correct.
Both players start off playing straight matchplay. If one gets 2 shots down, he gets a shot on every hole until he's only one down.
It's beautifully simple, but I hesitate to throw yet another idea into the mix. Perhaps next time?
Whitty are you and Ward 18 or 36 on Monday at Southerndown?
Have a nice day and Ciao.
