Unusual stipulation… nicely used to show his recently favorite theme!!
If we assume a immobile king at g7, the problem is a #4!
Reaching a square in N moves is strictly equivalent to checkmate an immobile King on the same square in N-1 moves, isn’t it?
I agree. But in this case, the interest is more in the path of the WS and the way B forces a particular route… rather than in the final mate.
You are right! IBlack defences using no-capture rule and white’s unique route being forced depending on black’s plan is interesting.
No.
White: Kh1 Ra7a2
Black: Bb7 Sa8
White can mate a royal dummy on g7 in one, but can’t reach g7 in 2.
Another difference: black can pass through zielfeld (or even white G could pass it), but with dummy king standing there the situation would be different.
