Do One Thing Well
A lot of strategy concepts compliment one another in Axis &
Allies. In this case, doing one thing well may sound contrary to the
all-or-none strategy, but they actually go hand-in-hand.
The underlying principle is that you want to work with a concentrated
force (ie clumping) and you want to deny your opponent the ability to
work with a concentrated force (spreading him out by giving him lots of
choices and an inability to do them all well).
If you have a choice between going after a couple of objectives
(equally important) and would probably achieve both, but it would be
costly, and going after a single objective and achieving it at minimal
cost, the latter choice is often the better one.
Itís not enough to kill lots of enemy units, you want to minimize
the number of your own units that you lose (a concept simple enough, but
hard for many players to put into actual practice).
For instance, your German air force has stayed fairly intact and you
now have an opportunity to attack a divided Allied fleet, and could
probably destroy both smaller fleets. What should you attack?
Some players might try to overextend themselves, seeing an
opportunity to kill all of the Allied navy and eager to begin the
slaughter. They may succeed, but at what cost? It is likely they may
lose all but a couple of German planes and the IPC value of lost units
will likely be very similar.
On the other hand, if Germany focuses 100% of their air force on one
of the two Allied fleets, they will still kill all of the naval units in
that fleet, but at a much lower casualty rate. Then they would be nicely
positioned on their next turn to use their still intact air force
against the remaining Allied fleet.
