An echo of a strange s#1 position. It is illegal for Black to move one of his rooks (because that would give a flight-square to the black king), so he is in zugzwang.

“2 solutions” seems to be missing from the stipulation.

And is the definition of SAT really correct? I think a king is in check if he can move to AT LEAST one square not controlled by the opposite side ( not “only one”).

Actually, I understand position of two black rooks as being pinned as their movement would mean check to black king. A kind of strange pin without pinning piece, based solely on the fairy condition. On the other hand, White can unpin them, by additional attack the sqaure the rooks are blocking.

Kjell is right. My working definition of SAT is “A King is in check if it can move to a square which is not observed by the opponent side.”

Of course “a square” means “at least one square” and not “only one square”. This is the way Popeye and WinChloe are understanding the SAT condition.

Interesting “Pickaninny” (?). The other two parts appear as tries!

While choice of 1.bxa6 and 1.bxc6 is plausible, nobody would really try 1.b6 instread of 1.b5 in such seriesmover.
