2 Capturing an enemy piece changes its color.
3 The converted piece must be moved immediatly.
6 Each capture transforms the captured piece into a friendly one
7 (changing color). Since it cannot remain on the capturing square,
8 it has to be moved immediately. This newly converted piece can now
9 capture (and thus "convert") another enemy piece, and so on.
12 Castling is impossible if any square traversed by the king is controlled
13 (directly or through a chain). Checks are ignored otherwise.

18 figcaption Black cannot castle because f8 is attacked: Qxe6, Pxd7, Nxf8
21 Pawns start on the third rank in an attempt to balance the game.
22 White has a large advantage otherwise, leading to a quick win.
25 The goal is to convert the enemy king. Note that capturing a king is
26 possible only if a king move is then available. However, a piece gives
27 check (concerning castle) even if it's impossible.

37 p If in a chain a converted piece cannot move, then you must reset the move.
