Superficially, you might think, since Contingency Pawns are immobilized, Knight has a quick fool's mate. Not so. If 1 N b1-c3 N g8-f6 2 N c3-b5, then 2 ... N f6-e4, and Black Knight is inviolate thwarting any checking move to d6, since White Pawns cannot move either, although himself, the Knight, off-centre for the same finale on the White King. If then the g1-Knight starts out, that gives Black time to move Pawn g7 and exit the Bishop. If instead, contrary to move towards King, White moves 2 Pawn b2-b3, that Pawn can any move later advance three whilst unimpeded b3-b6 by the RANK OBLIGATION. Yet from b6 she has no evident advantage to take a7 or c7 because she can be gobbled immediately by Rook or Queen. So it goes in normal development needing long-term planning not subject to fast fixes and fusses. Being possible Computer may find an opening spoiler, baffler or outright cook, as designers, we just hereby now give King the mediaeval one-time King's leap Knight-like -- which should be sufficient in the event -- as final add-on rule accompanying the Contingency Pawn Mutator just in case. Moreover, King's Leap and obligatory Knight openings are aesthetic pair. Thus in the large, King may Castle as usual, maneuvre with central Pawns to ''palace,'' or exercise King's leap once only. After a Castle, no King's leap allowed, but the singular Leap and routine palacing are very mutually compatible. Little 8x8 is not the main feature for Contingency Pawns, rather 8x10 and 10x10, which are having ancient 13-century Gryphon and new-fangled Bison (who is liberally applied unnuanced Falcon, invented 1992).
