Bethpage Black has a relatively good mix--1 through 3 are relatively easy (even I was +1 through 4 there once, bogeying 1 and parring the next 3), 4 is difficult, but possible to make par or birdie with three good shots, then:
Five (difficult)
Six (Moderately difficult, without a good drive and second)
Seven (difficult)
Eight(Moderate)
Nine (Moderate)
10-11-12 (Look out!)
13(not too difficult, just long)
14 (just hit the green)
15,16,17 (very, very difficult, difficult, and difficult)
18 (not too difficult)
So there is ebb and flow here. In contrast, Bethpage Red starts out with a ball breaker (#1, 471 yds par 4), and then next 7 are relatively moderate difficulty holes--birdies and pars can be made.
10-15 are strong holes, with 14 and 15 being the climax, if you will, requiring long, straight drives and long irons or fairway metals to the green, 16 and 17 ease up a bit, and 18 is very difficult into the south/west wind.
There is "ebb and flow" here, too, but in a different pattern.
I'm not sure if other Tillinghast courses are like this, but many courses collectively thought of as "good" have an ebb and flow to them; I would welcome contrasting opinions from mine on those two examples.
