Yes. It is the same. What we have here in chess.com's e-chess platform is "server-based correspondence chess." You cannot explicitly define correspondence chess with reference to timing controls - except, obviously, to point out that they tend to be a lot longer than those for OTB chess. :-)
Some correspondence chess servers use a "simple delay" (non-accumulative) as does chess.com; others (which I won't name here) use a sort of Fischer-style 'clock,' allowing the players to accumulate their un-used per-move time.
Ok. Blogs are just diaries published through a server. I get it.
Is Online Chess Correspondance Chess on a server?
**************************************************************************************
Is online chess, as offered here on Chess.com, supposed to be the same as Correspondance Chess, subject to the exact same interpretation of rules, ethics, conduct of play, and attitudes among its pusuants?
I state: No. They are different.
Subtle, but distinct and significant differences that call for a tweaking of the set of rules, ethics, etc. The subtleness makes it is easy to think they are the same, but the distinctions signal that they are not!
One major disctinction is Time Controls. Not just the amount of time, but how it is doled out and the accountabilties it imposes upon the participants.
Another MAJOR distinction is that engines are allowed in server based Correspondance Chess and here on Chess.com in Online Chess they are not.
Now, with regard to Time, it is handled in complete different fashion here Online than it is in Correspondance. On Chess.com, time allowed per move is never accrued (accumulated) and the time frame stays stable throughout each and every independant game with the time framweworks pre-determined.
In Correspondance Ches there is a block of time that is allowed to be managed in any way the player chooses, such that one can think and analyse 30 days for one move without over stepping their time limits if they are engaged in 10 move/50 limits (The normal setting on ICCF). They would then have 20 days for their next 9 moves. By moving faster, a player gains more time for latter in the game. This is not possible here Online, and is the CRUX.
I repeat: This is THE significant difference in the actual rules that leads to major differences in in the development of time managment and time strategy in both games and is the critcal reason why a different approach need be taken from the onset of creating a code of conduct and ethics for online chess.
So, I argue that this application of the Correspondance Codes of Conduct is fallacious and the direct cause and root of many problems, disagreements, and conflicts that all lead to wasted bandwidth ($$$!) and more work for moderators and staff. Much of it will be solved by simply acknowledging the differences and creating an independent set of standards to be followed by all Online players.
