3 - s#2 sat with royal Grasshopper

SAT : In "SAT", a King is in check when... it threatens to play on a square where it is not in check in the traditional sense! Thus, bQ, bR & bB are pinned, because the royal grasshopper must not have access to a1, c2 & d1. It is checkmate if the King cannot deny himself this "free" square. SAT was invented by the Slovakian problem solver Ladislav Salai (hence "sa", the "t" being the end of the word "mat") at the end of the 20th century.

6 - h#2 2 solutions back-to-back

Back-to-back : if two pieces of opposite colour are "back to back", for example a white one on e5 and a black one on e4,
they exchange their roles. Suppose a white knight e5 and a black bishop e4.
White to move, the knight plays as a bishop, black to move, the bishop plays as a knight.
