That Column of Attack which is posted upon the superior Strategic front
as compared to the front occupied by the immediately opposing formation
(cf, Grand Tactics, pp. 117 to 275), has the advantage in position.
This relative advantage and disadvantage in position of the Column of
Attack is expressed by the first term of the Strategic Syllogism, viz.:
(I.)
+A
----
-A
or
(II.)
-A
-----
+A
In the first instance (I), the White Column of Attack has the advantage
and the Black formation has the disadvantage; in the second case (II),
this condition is reversed.
