Shortly after Macdonald & Raynor built the first Biarritz green at Piping Rock an article was written in either Golf Illustrated or American Golfer describing the strategy of playing the hole. Bear in mind that at that time a long hitter could only hit the ball about 180 yards in the air. The "thrill" of playing the Piping Rock Biarritz was to hit what was referred to as a "push shot", a low line drive of sorts, that would hit on the front section, which was cropped low and not cut as putting surface, ......... hit a low line drive, land on the front section, watch the ball dissappear through the swale and "hopefully it would reappear on the green"An article describing the Biarritz at Willie K. Vanderbilt's (original) Deepdale course (1925-1927) reads similarly.Piping Rock's Biarritz was never designed to been fully planted as green, very few originally were. Until a few years ago there were only two or three Biarritz greens fully "planted". There are an awful lot of them now full "double greens" (if we can call them that). Some of these can be attributed to Tom Doaks work and some may be a result of my "meddling" while visiting these courses ...... :-)These greens are normally 225 to 250 feet long and when in full-blown putting surface are very dramatic. Shoreacre's Biarritz, their 8th, may be the largest in area as was the one at my course The Knoll. The Knoll measures 248 yards from the tips - it was originally planted full green by Banks in 1928-1929 but it was never reestablished after it was cut back to a single green during the period of WWII. But we still have the two wonderful little mounds in the "front" area that were designed to deflect some of these low "liners" - I've never seen anyplace else. Most were taken out because no one knew what they were for. I have a copy of a Charlie Banks greens (only) blueprint from his Westhampton Oneck course that clearly shows these mounds as well as the usual "horseshoe" features Raynor and he put into those approach areas.Yale's swale (that rhymes) is the deepest and Creek's is the shallowest because of the high water table (for those who have never seen pics of the Creek's 11th, the entire green and little else is an island).There were a number of "single green" Biarritz' built - by that I mean the front area was not "elevated" - Westhampton's 9th and Otto Kahn's 8th (I think it is/was the 8th) are two that come to mind and I have a hunch the Biarritz at Lido (along the beach front) may have been a "single green" version.
