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.
Messigny Chess: Instead of an ordinary move, any unit (Ks included) may be swapped with another of the same type and opposite colour, provided neither of the units involved was swapped on the previous move.
Grasshopper(G): Moves along Q-lines over another unit of either color to the square immediately beyond that unit. A capture may be made on arrival, but the hurdle is not affected.

In the third solution of 1133 we have an unnecessary check from wKf3. I suggest the following version:
wKa1 wSc3 bKc5 nGd4, h#2 3 sol
1.nGd4-b6 Sc3-e4 + 2.Kc5-b5 Se4-d6 #
1.Kc5-b4 nGd4-b2 2.nGb2-b5 Sc3-d5 #
1.Kc5-c4 Sc3-e2 2.Kc4-d3 Se2-f4 #
….Of course, with Annan Chess rules.
