Chechessee Creek is a great template for designing a tough, fun course on flat, flat land (makes Yeamans Hall look like there is a lot of undulation). The formula I observed at Chechessee is small, push up greens, with a good and bad side to be on (short and straight is excellent at Chechessee) if you miss. Holes that bend both ways. Light use of fairway bunkering to dictate tee balls as its more about the dog legs and tree lines. Lots of variation in length within the 3, 4, and 5. Most of this is good desgin regardless of land movement but I think the small, thoughtfully protected greens and use of doglegs and treelines make Chechessee really well done for such flat land. Lots of restraint there but a super fun place to play. Really tough too.
