+p.
+ The following diagram seems to show a mating pattern, but the king if
+ "attacked" by a checkered pawn – which still belongs to white.
+ Therefore, it can be considered that it's not really a check because
+ white is unable to "give back the turn".
+ Without the black bishop on a7 it would be mate (without debate), because
+ the king could virtually go to g1 before being captured by the pawn-chamaleon.
