In each match, each player chooses his variant (which may be Orthochess),
and the two players send simultaneously their moves in four games (this
takes care of games which are a sure win for one side).
In a round-robin, win, draw and loss are valued the usual 1, 0.5 and 0,
and you can have the players share four points or have their scores
normalized to 1, 0.5 and 0.
In match play, first first win (in one variant) is awarded an extra 0.11,
and second first win (in the other variant) gets only 0.10, so this may
untie the match.
