I agree. I’m not sure why side sloping greens are rarely found. In fact I am finding it difficult to think of any that would fit into the classic category. Wentworth #15 gets them thinking but it is hardly a great hole.
The 23rd hole at my home course, Cumberwell Park, has such a green and I think it creates strategy on two levels. It is a dogleg to the right with a marshy area down the left, a wide fairway and a couple of insignificant bunkers on the right. The tendency is to get greedy, take the corner on while at the same time bailing out away from the wetlands. This then leaves a downhill second to a green that slopes away from you and with dense undergrowth and OB hard left next to the green.
The braver line is to get close to the wetlands and give yourself an open shot to the green where the slope can often help feed your second in close.
The second level of strategy comes on the approach where a nervy push right away from the OB will leave a nasty down hill chip, over a swale to a rapid green sloping away and towards the OB.
I mean it’s not a great hole, but it’s a simple strategy that keeps people thinking and punishes the timid.
Perhaps the Archies can explain why it is not often used, or is it but we are not as aware as we should be?
