+p.
+ Shinobi Chess is a chess variant designed in 2021 by Couch Tomato.
+ The chess army (the "Kingdom", black) has invaded the land of the Sakura
+ Clan ("pink"). While initially unprepared and having very few pieces
+ available, the Clan is very resourceful and can instantly recruit and
+ summon allies to defend at a minute's notice!
+
+p.
+ The Clan starts with almost all of its pieces in hand, and can drop them
+ on its side of the board (first 4 ranks) in lieu of moving a piece.
+
+p
+ | In addition to checkmate,
+ | one can win by bringing the king into the final rank ("campmate").
+ br
+ | Stalemate and repetition are both losses.
+
+h3 New pieces
+
+p.
+ There are five new units unique to the Clan: Ninja, Samurai, Lances,
+ (Wooden) Horses, and Monks. Captains are a new piece available to both
+ sides, but only the Clan starts with one on the board.
+ Ninja, Samurai, and Captains do not promote (see below).
+
+p.
+ The Clan's king is called a Kage (K) and has a different symbol, but the
+ change is purely aesthetic and thematic: it behaves like an orthodox King.
+
+ul
+ li Captain (C) – Moves like a King. Pawns promote to a Captain.
+ li Ninja (J) = Knight + Bishop.
+ li Samurai (S) = Knight + Rook.
+ li Monk (M) – One-step bishop.
+ li.
+ Horse (H) – Moves only forward two squares,
+ and then one square to the side.
+ li Lance (L) – Moves only forward, like a unidirectional rook.
+
+p.
+ Clan minor pieces are considerably weak. However, with a little
+ resourcefulness, they can trap the stronger Kingdom pieces
+ and even win the battle.
+
+h3 Promotion
+
+p.
+ Pawns promote into Captains when reaching the 6th rank.
+ All minor Clan pieces also promote upon reaching the 6th rank (or beyond):
+ul
+ li Monk into Bishop.
+ li Horse into Knight.
+ li Lance into Rook.
+
+p
+ | Clan Rooks and Bishops look different, but the changes are purely
+ | aesthetic. Note that the symbol on the Bishop is a
+ a(href="https://handwiki.org/wiki/Sauwastika") sauwastika
+ | , not a swastika.
