Offset greens that dictate angles of play back to the tee are a good method to identify proper strategy and the ability to execute that strategy. Courses in the UK if they have offset greens at all, tend to have one or two. Offhand, I can think of 3rd at Muirfield, the 16th at Nairn, 17th at TOC, 13th and 15th at N. Berwick and the 13th at Prestwick.
Among some US architects this feature seemed to be used in greater numbers. Some examples include:
Merion (it has offset tees, too) has the 3rd, 6th, left rear of 9th, 10th, 12th, 15th and right rear 16th; Bethpage Black 3rd, 4th, 5th, and 13th; Old Course at Homestead 2nd, 6th, 8th, 14th and 17th; Cascades 2nd, 3rd, 4th, 6th, 12th and 13th; Baltusrol Lower 8th and 17th; Winged Foot West 5th, 6th, 15th; Oakmont 2nd, 4th, 6th, 7th, 8th, 12th, 14th, 15th, 16th and 17th; Pinehurst #2 1st, 2nd, 7th, 9th, 10th, 11th, 12th and 17th; Pebble Beach 3rd, 8th, 11th and 17th; Atlantic City CC 2nd, 4th, 6th, 7th, 10th, 11th, 14th and 15th; Pine Valley back left 3rd, 12th and 13th; Leatherstocking 3rd, 7th and 9th; TCC Brookline Composite 2nd, 4th, 10th, 12th, 15th and 16th; Westchester CC 2nd, 3rd, 8th and 16th; Newport CC 10th, 14th and 17th; St. Louis CC back right 1st, 4th, 8th, 11th, 16th and 17th; Shinnecock Hills 6th, 7th, 8th, 9th, 10th, 13th, 16th and 17th.
I think the use of several offset greens on a course, especially firm and with proper maintenance practices in fairways and run-ups, are beneficial to interesting and challenging play. It seems to me they are a characteristic of some of the best courses in America and are instrumental in defending par.
