[RCH "Robot/Human"]

RCH stands for Robot/Cyborg/Human.

If the opponent is 100% mechanized (computer) then the opponent is considered
Robot.

If the opponent is aided by a human (e.g. 'Advanced Chess') then the opponent is
considered Cyborg.  This designation may also be useful for Postal or other
correspondence type formats where some of the players may use computers.

If there is no assistance from computers, then the opponent is human.

There may be additional sub-variations.  For instance:

Human with Database lookup only (examines openings and what other people have
played at various positions in his database)

Human with book assistance (human does not use any electronic assistance, but
does consult books like NCO, etc.)
