Generally speaking you are allowed to use opening books (any books
really) and databases and a longer time to move in. You are not
generally allowed to use a chess engine like Fritz.
When you are playing CC you should expect to be playing against
opening books, databases, and chess engines since they cannot really
be stopped.
are you here to play chess! or just popped in to say hello? hello there!
anyway! i too have read of such " rules" ive played chess for over 30
yrs before computers! its always been that your private notes,libarary
could be consulted in playing your game.even consultation amonst
friends on your "next" move. correspondence chess has always been
a "LEARNING" GAME! played in your own time ! days,weeks can go by
before you know what your opponents next move will be! plenty of
time to plot and plan! SETUP your own game boards. play on your
moves. all this can be done before making your next move.!
computers well they are new! databases vs "a good chess book" i
guess databases are a modern day version of a "a good chess book"
anyway! there are many here willing to play chess. how about joining
in! use the open invite feature. post your invite. im sure you wont
have long to wait before your invitation is accepted!!
Your understanding is correct for almost all correspondence chess
federations.
Most have rules against the use of chess playing programs, but the
use of databases or books for reference is permitted. The only
correspondence chess organization I know that does not have rules
directly against the use of chess playing programs is the International
Correspondence Chess Federation (ICCF). Still, the use of a chess
playing program not considered good form, and most ICCF players
are strong enough to beat chess playing programs anyway.
