It is better to have also zunzwang in the solution to do the mate more hard to find(at least for null movers) My mate in 17.5 problem that I posted in another post(black begins and say mate in 17 against itself) combine zunzwang with the fact that 18 plies of the solution are not check moves and not captures. I will not be surprised if no program can solve it in 24 hours. Uri
