Forrest Richardson,
I tend to place golf courses into categories.
Championship and Sporty would be two of those categories.
After playing a golf course I make a determination on which category I feel it falls in.
As an example, I would categorize Shinnecock as a Championship golf course, NGLA as sporty.
Aronomink, Championship, Merion is a hybrid championship and sporty course in my mind.
Pebble Beach, Championship, Cypress Point Sporty.
Winged Foot, Championship, Bethpage Black, Championship
The Creek, Piping Rock, sporty
Baltusrol & Plainfield Championship, Somerset Hills Sporty.
Hidden Creek Sporty.
Length is certainly a factor in determining courses that fall into the Championship category.
But, that's just my own view on Championship golf courses versus others
