yes position is about zugzwang. the easiest way to push the zugzwang
over the horizon to a mate in i think 18 or so is to put some illegal
pawns ont he board.

the combination as we'll get it in games is real easy!

with the illegal pawns there then black can delay zugzwang with
b5 a4 c4 to then see a mate in 9 against itself.
