The governing body for computer chess is the International Computer Chess
Association (ICCA).

http://www.dcs.qmw.ac.uk/~icca/index.htm

This organization was founded in cooperation with FIDE.

The rules for live computer vs computer games are patterned after the rules for
blind players.

Before each WCCC they typically announce the rules in their journal.

Basically you have a chessboard with pieces, a clock, two operators, and two
computers.  The monitors are placed where both operators can see them.  The
clock is the official time, and the board is the official position.  Both
operators record moves as in a human vs human game.  The operators serve as
proxies for the computers, they do what the computers tell them to do, and they
tell the computers the condition of the board and clock (they relay moves and
keep times current).

A basic goal is that the operators not influence the game either way.

There are rules about exactly when you can correct the computer's clock, but I
think they are archaic and need a rewrite.

If a program offers a draw and the other one accepts, it's a draw.  If a program
resigns, the game is over.  The operators can offer draws, accept draws, and
resign, with the approval of the tournament director, who typicall insists that
things be pretty clear.

Operator errors are corrected, as much as possible, without penalty.  Some
number of crashes or other stoppages are allowed, but if there is too much
crashing the clock keeps running while the computer is restarted.

An informal rule is that the clock is not started until one of the programs is
out of book.  That avoids a meaningless clock scuffle at the start of the game.

Adjudications based upon best play are typically done after some period of time
has elapsed.
