2 | | Every captured piece change color and can be dropped back later. | |
3 | | Most pieces can promote on the three last ranks. | |

6 | | The following description is often borrowed from the | |
7 | a(href="https://www.pychess.org/variant/shogi") Shogi guide | |
8 | | on pychess-variants, where I found the pieces images. | |
9 | | Shogi is played on a 9 x 9 board. | |
10 | | The side with a black king starts the game. | |
11 | ||
12 | p. | |
13 | Captures are achieved by replacement on the destination square. | |
14 | Any captured unit is added to a reserve of "pocket" pieces. | |
15 | At each turn you can drop one of these pieces instead of moving one. | |
16 | A dropped piece must be able to move, theoretically, considering only its | |
17 | position on the board. | |
18 | Pawns cannot be dropped on a file already containing a pawn of the same | |
19 | color. They also can't be dropped to give checkmate. | |

90 | and he also captures in this way. | |

92 | h3 Promotion | |
93 | ||
94 | p. | |
95 | All pieces except the gold general and the king can be promoted, | |
96 | by playing a move arriving on one of the three last ranks. | |
97 | Promotion is optional unless a normal move would result in a blocked piece. | |
98 | Capturing a promoted piece put the non-promoted form in the reserve. | |

110 | Minor pieces in this game are the pawn, knight, lance and silver general. | |
111 | They all promote to a gold general: only their appearance differ. | |
112 | The rook and the bishop promote respectively into a Dragon King and a | |
113 | Dragon Horse, which allow them to move like a king in addition to their | |
114 | usual movements. | |
