Voytek, you refer to both visual and psychological intimidation. Among great rolling parkland courses, it seems like 75% or more have bunkering that is intimidating in some way, but that the mode of intimidation varies a lot.
The Raynor / CBM bunkering style (at Yale and elsewhere) strikes me as based on psychological intimidation ("steep and deep") rather than the visual intimidation of looking out a massive sea of sand. A lot of Dye courses (The Ocean Course, Blackwolf Run River) seem to fall into the "deep rather than visually bold" category as well.
The MacKenzie style strikes me as based primarily on visual intimidation, especially at Cypress Point, RM, and Pasatiempo (although RM's got some pretty deep bunkers too). I think Pasa probably fits into the same category of "rolling terrain, deep bunkers" as RM and Bethpage, though if I recall correctly the bunkers aren't quite as deep. Augusta, even though it's got some thoroughly bunkered greens, is an exception: rolling parkland without intimidating bunkering. The "Augusta style" (Peachtree, etc.) seems like accounts for a decent share of the other 25% of great rolling parkland courses, but it isn't really Mac's style.
Tillinghast strikes me as more of a chameleon. At Bethpage, the bunkering is as in your face as anywhere. At Winged Foot, it's just as dominating strategically but less dominating visually: when I read Tillie's description of WFW as a "man-sized course," I always think that Bethpage must be a giant-sized course, at least in terms of bunkering visuals. Fenway and SFGC seem closer to Winged Foot than Bethpage, but probably somewhere in between.
