+p.boxed
+ | No captures. Pieces under attack insufficiently defended change color.
+
+p.
+ Conversion occurs when the amount of persuasion exceeds the
+ amount of support. Pieces persuade and support according to
+ their standard attack moves. Opposing pieces persuade, friendly support.
+
+p.
+ For example on the following diagram, 1.Nf5 attacks g7.
+ Since the bishop is undefended, it turns white. Same for the pawn e7.
+ Then, the rook f8 is converted. This allows to convert both the knight
+ on d8 and the bishop on g8. Finally, the pawns f7 and h7 are under attack
+ and thus also change color.

+ The game ends when a king is converted, and the side cannot convert a king
+ at the next turn. Note that kings may be exchanged, as on the following
+ diagram: 1...g6 would convert back the original black king on e7, but
+ 1...Nb6 is also possible, turning the white one on a4 into black.

+p Notes:
+ul
+ li.
+ It is possible for pieces to persuade or support through other
+ friendly pieces. For example, rooks and queens in the same orthogonal
+ or bishops and queens in the same diagonal.
+ li.
+ The Pawn is forbidden to move through a cell which is overly persuaded
+ during its initial two-step move.
+ li.
+ A King is allowed to move to cells which are being persuaded as
+ long as the level of persuasion is not greater than its support.
