It seems to me that it's not so much that the rear guard is useless; rather, it's that the alternative plays either leave extra shots for no good reason, or put checkers where they don't belong. Here's a variant:





White is Player 2

score: 0
pip: 144
Unlimited Game
Jacoby Beaver
pip: 172
score: 0

Blue is Player 1
