Annan Chess: If two pieces of the same colour are standing close to each other in N-S-direction, the front piece moves only like the rear piece as long as the contact is existing. The front piece is that piece that is closer to the own promotion line. White/Black Pawns on the 1st/8th rank cannot move, but can give their kind of moving to a front piece. Officers moving with the power of a Pawn to the promotion line do not promote; if they make a double-step with the power of a Pawn, they cannot be captured en-passant; but officers with the power of a Pawn can capture a Pawn en-passant.

Annanchess specific Stalemates achieved in two solutions as follows:
1. In Sol(1), white's last move (nSa2) immoblises all black pieces including the nS itself;
2. In sol(2), the nS is immobile since if it moves like a P to a1 it will be self-check!(Author)

Annan chess is interesting move effects are like ‘Back-to-back’ applied for same color front pieces only.
This problem is good but for the repeated move nSb4, both times moved by black.
