1 - h#3 Circe
the standard form of Circe, in which a captured unit (not K) is reborn on its game array square. Pawns are reborn on the same file as they are captured; Rs, Bs and Ss on the same colour square as that of the capture square. Fairy pieces are reborn on the promotion square on the same file as the capture square.Jean-Pierre BOYER &Pierre MONTREALProblème, 1968

2 - h#2 - Take&Make - 2 solutions
a unit (Ks included) upon capturing must make a further non-capturing step in the manner of the captured unit as part of the same move. Such a movement must be possible, otherwise the capture may not be made. A capturing pawn may not be conveyed to the base rank. A pawn promotes only if it is conveyed to the promotion rank by this part of the movement. Checks are normal.Thomas MAEDER &Ulrich RINGTT Andernach, 20062nd Place

3 - hs#2 - AntiCirce Calvet - with Lions, Leo, Grasshopper et Nightrider !!!
AntiCirce a unit (Ks included) which makes a capture is immediately reborn (on the same square in which it would be reborn if it were the captured unit in the corresponding Circe variant). The rebirth square must be vacant, otherwise the capture is not legal. (A threatened king capture is only check if the capturing piece can be reborn). By default, a unit may capture on the same square as the square upon which it is to be reborn. The same rules for Ps, Rs and Ks as for Circe apply make any number of steps in the same direction up to the hurdle, and any number of steps in the same direction after the hurdle. Leo Pieces which make non-capturing moves like a rider, and capturing move like the corresponding member of the lion family. makes one or more steps in the same direction up to the hurdle, and a single step in the same direction beyond. rider which makes moves consisting of one or more parallel (1,2)-stepsMario PARRINELLOStrateGems, 2006

11 - h#2 - Andernach and Chameleon black pieces - 4 solutions
a unit (not K) when capturing, changes colour. a chameleon exists as an S, B, R or Q; and after each move transforms to the next in that sequence (Q becoming S). A chameleon pawn does not transform, but promotes to a chameleon piece in any phase. In the presence of chameleon units normal pawns may promote to normal or chameleon pieces.Volker GULKEThe Problemist, 20021st-2nd Prize
