A retro stipulation by Tim


CSE link: https://chess.stackexchange.com/questions/46911/long-play-sequences-that-are-forced-in-both-forward-and-backwards-direction/46917?noredirect=1#comment76781_46917

Make a position A which forcibly turns to B within n moves. But also the only position that could reach
B in n moves is A.

Here is my 3 move try (Black to move):

(= 16+4 )


(Obvious forward and retro play see link, if it is not obvious :-)

You surely can top this!
