1 - h#3 2 solutions take & make

Crisan, V & Balasubramanian
2017

white Pa2b2a4 Ka3 Bd6 Sb5c2 Re3 black Rb4c5 Sd4 Bb3d3 Kh6 Ph5h7g7
hs#3 Take & Make(8+9)
2 solutions
: white plays and black collaborate until the last move
where white forces black to checkmate in 1 move
. : after a take ("take"), the captured piece is required to make a complementary move ("make")
without taking with the moving way of the captured piece (a kind of posthumous tribute)

Tritten, P.
2008

white Pe3 Be7 Rh6 Kb1 black Pg7f4g2e2 Bf1d2 Rg8g3 Ke1
h#2 infra-functionary(4+9)
Anti-circe
b) ♚e1-->d1
: the captured piece is reborn on its original square if it is free, otherwise the capture is illegal
. : In infra-functionary (foolishly called " defiant ", which means nothing,
by the adepts of the political-speak, whereas "infra-functionary" imposes itself as logically symmetrical of "ultra-patrol")
one can play a unit without condition, it is only to capture that one must be observed by an enemy unit.
