h#3,5 with Maos

Creeping knight taking a rook step, then a bishop step
. The finishing square of the rook step must be free

this move became possible with the liberation of the square d4
} 3.Bd1-f3 MAf4-d5 {

Reciprocal batteries and echo-chameleon.}

h#3 Circe with neutral pawns

a captured piece is reborn on its original square if it is free, otherwise it disappears
. : pawn which can be played by both sides
. A neutral pawn is promoted to a neutral piece

} 2.nPc2-c1=nS nPc7*b8=nR[+nBf8] {
} 3.nRb8-e8 nPf7*e8=nQ[+nRa8] # {

semi-mirror. Impossible is 4...Rxe8 because a neutral Queen would be reborn on d1 ; for the same reason 4...fxe8nB would not checkmate.

AUW.}

} 2.nPg2-g1=nQ nPe7-e8=nB {

} 3.nQg1-g8 nPf7*e8=nR[+nBc8] # {

Triple check. However, a double check would suffice for mate, the usefulness of Bc8 being limited to controlling d7 and f5.}

} 3.nPf2-f1=nR nPf7-f8=nQ {

} 4.nRf1-f7 nPe7*f8=nS[+nQd8] # {
Triple check, but the role of nQd8 is limited to controlling d6, c8, e8 and... d8, because 5...Kxd8 would revive a neutral Queen on d1.}

#2 with Locust

kind of Grasshopper that "eats" the sautoir, which is necessarily an opponent piece.
Like the Grasshopper, it lands just behind the sautoir

Levman theme, say the experts. Semi-beotians will be content to notice the Novotny try and the defensive Grimshaw,
while appreciating the finesse of the refutations.}

serial h#6 with Grasshoppers and Double Grasshoppers

moves like a Queen but needs a sautoir behind which to land.
This move is only possible if the square behind the sautoir is empty or occupied by an opponent's piece
as its name indicates, this piece performs 2 successive Grasshopper movements

Solution

h#2 Take&Make

a capturing piece is required to make a movement with the characteristics of the captured piece immediately after capture.
This movement must not be a capture

Pierre TRITTEN

white Pd5 Ka8 Bd3 Re3 black Pa5 Kd4 Rc4 Se7

h#2 Take&Make(4+4)

Solution

{

} a) {
} 1.Rc4-c6 Re3*e7-g6 2.Kd4*d3-a6 d5*c6-c4 #{

} b) bPa5-->f7{a5-->f7
} 1.Se7-c6 Bd3*c4-a4 2.Kd4*e3-e8 d5*c6-e7 # {
Characteristic mate: bK cannot capture e7 because he would have to play a white pawn move and would end up in e8.}

#3 AntiCirce

a capturing piece returns to its native square if it is free. Otherwise, the capture is illegal.
However, we distinguish the case where the capture is made on the rebirth square,
which is thus occupied at the beginning of the move by an opponent's piece.
This capture is allowed in Calvet Anti-circe, whereas it is forbidden in Cheylan Anti-circe
