How about "Later Play Chess" as in the old records, LP (long play)?
Online Correspondence Chess (OCC)
How about "Eternal Chess", or "You may die before this game is over Chess"?
... cant believe nobody has mentioned it ... so simple, how could everybody miss the right name...
How does that allude to the extended time used for the game?
Your descendants play your opponents' descendants until the game finally ends.
Obsessive Compulsive Chess (OCC)
If eChess doesn't work because all of it is electronic and Correspondence doesn't work because snail mail is not involved then the previous mentioned email-chess should serve as the modern version of correspondence without implying that it's live.
My vote would be for naming it: TURN BASED CHESS
(I do not know whether is was named in the above 204 earlier postings).
Why: since indeed lots of players would not realy understand the characterization 'Correspondence Chess' + TURN BASED represents is in fact somehow the 'opposite' of 'instant chess/ live chess' which is in use for the one of the other forms of conducting style of playing chess.
"Pending Play Chess"
I don't know if it's been previously suggested, but "Intermittent Chess" is about the best fit I can come up with.
We still happily use the term 'correspondent' to refer to news reporters who have long since given up the practice of sending their reports via the postal system.
Why is it so hard to allow users of chess.com to take for granted the fact that their 'correspondence' won't require any stamps to be licked?
Despite my little jest above, OCC is a good description. But I guess that the site doesn't want to use an abbreviation and the whole lot is too long, so that just brings us back to CORRESPONDENCE CHESS.
My vote is cast.
"Week Long Chess"
Sorry for this one, "Geritol Chess" (spelling is probably wrong)
How about "Survivor Chess" since each game takes a good 39 days to complete
argh. no closer than when we started... there is no right name :(
Do you mean "Genitol Chess"?
Interruptible? Intermittent? Casual? Days-Per-Move?
...or the more snappy 'corrie chess'. This could also refer to the British drama series which has been running for over 51 years - like some of the tournaments here seem to.
