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. |

32 | King Faceoff — As in Xiangqi, Kings may not face each other | |
d35c037e | 33 | (on a file or rank). |
1e8a8386 BA |
34 | li. |
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 | |
d35c037e BA |
37 | soldier onto an open square in rank 5. |
38 | li Campmate — A king that reaches the final rank wins the game. | |

40 | Stalemate — As in Xiangqi, stalemates | |
41 | and moves repetitions are a loss. | |

d35c037e | 46 | Four new units on the Dynasty side: 6 Soldiers (2 start in |

47 | hand), 2 Cannons, 2 Elephants, and 1 Advisor. |
48 | p. | |
49 | The Chariots are equal to the Rooks and use the same abbreviation (R) | |
50 | — the difference is purely cosmetic. Similarly, the Kings are the | |
51 | same, but just appear different. | |

54 | li. | |
55 | Soldier (S) — The Soldiers can move one square orthogonally forward, | |
56 | or lateraly. | |
57 | li Advisor (A) — The Advisor moves and captures exactly like a king. | |
58 | li. | |
59 | Cannon (C) — The Cannon moves like a rook, but needs an | |
60 | intervening piece in-between to achieve a capture. | |
61 | It cannot hop over another cannon, however. | |
62 | li. | |
63 | Elephant (E) — The Elephant is a leaping piece that moves | |
64 | diagonally one or two spaces. | |
