But doesn't "Correspondence Chess" sound a bit "formal" and "old-fashioned?" So how about this? --
"Really Modern, Totally Cool, Space Age Chess!!" (Catchy, huh?)
Another "old fashioned" idea that my father (who will be 80 next week) and I were discussing at lunch today: "right the first time".
There's nothing wrong with old fashioned, especially when half of the the alleged chess teachers on this site cannot produce a single clear sentence.
"Your grandfathers chess."
