Would be an interesting variant to have to go for full elimination

If you run your pawn up to the other end you can promote it to a king and use it to continue your mother’s mission to keep your brother out of jail.

Other interesting strategies:

• Barely moving the pawns.
• Spending almost all your remaining moves capturing your own (and only your own) pieces.

I'm guessing this is an AI photo, then?
