11 | Synochess is a variant designed in 2020 by Couch Tomato. |
12 | The idea is to permit the western chess army (white) to fight | |
13 | against the xiangqi or Chinese chess army (black) in a fair manner. | |
14 | The white army is called the Kingdom, while the black army represents | |
15 | an amalgamation of xiangqi and janggi (Korean chess) | |
16 | and is called the Dynasty. | |

19 | The name Synochess is based off an earlier name, Sinochess, but it was | |
20 | changed as the Dynasty became less "Sino" (as in Chinese) and more a | |
d35c037e | 21 | mixture of Chinese and Korean. Instead, the prefix syn- means together. |

35 | Reinforcement Soldiers — Black starts with two soldiers in hand. | |
36 | Instead of moving a piece on the board, the Dynasty player can drop a | |

49 | The Chariots are equal to the Rooks and use the same abbreviation (R) | |

51 | same, but just appear different. | |
