Instructive example of cyclic dual avoidance and a new proof of AMU condition usability for various effects.

An interesting problem with a good flight-giving key. The dual avoidance uses 3 different mechanisms: opening of black line, guard of mating square, and move of King so that white move is not a double-check.

However it is a pity that after 1…Kxe7, 2.Qxc5 would not be mate anyway.

Can d7 be shifted to f7?

: I don’t understand what you mean about shifting d7 to f7. The bPd7 is necessary in order to block the square d7.

I meant if a suitable guard could be found for d7.
