4 - serial h#6 2 solutions avec Moose
Moose The moose, playing as a grasshopper along the path of a queen, makes an angle of 45 degrees from the sautoir,
in relation to the arrival square of a Grasshopper.
For example the Moose h4 can go to f1 or e2 via the f2 sautoir (e1-f2-f1 = e1-f2-e2 = 45 degrees).
Moose e5 can move on f3 or g4 via sautoir f4 (these last moves as a knight, but it would go to g2 or h3 if the f4-square was on g3).
Note that Moose f4 is pinned by neutral Moose e5 (sautoir h2) ;
besides, without it, Black would be checkmated because nMe5 would have no possible escape.

6 - 2# boléro
boléro capturing moves are played normaly.
A non-capturing figure adopts the march of the one initially on the same file.
It plays like a Rook if it is on the "a" or "h" file, like a Knight if it is on "b" or "g", etc.
For example, the rook f8 cannot go to f6, but neither can the black king because said rook would "normally" take it.
Similarly (after 1 e7!) the bishop g8 cannot go to e6 (the Fh6 could!), but neither can the black king.
