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
21 mixture of Chinese and Korean. Instead, the prefix syn- means together.
24 li The Kingdom (white) always moves first.
25 li The Dynasty (black) cannot castle.
26 li Dynasty soldiers do not promote (on last rank).
32 King Faceoff — As in Xiangqi, Kings may not face each other
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
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.
46 Four new units on the Dynasty side: 6 Soldiers (2 start in
47 hand), 2 Cannons, 2 Elephants, and 1 Advisor.
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 The Soldiers (S) can move one square orthogonally forward or lateraly.
55 li The Advisor (A) moves and captures exactly like a king.
57 The Cannon (C) moves like a rook, but needs an
58 intervening piece in-between before it can land or capture something.
59 It cannot hop over another cannon.
61 The Elephant (E) is a leaping piece that moves
62 diagonally one or two spaces.
