UCI code for "pass" in Janggi Game

[levis77]

Hello Fabian,

I am trying to use UCI to run fairy stockfish, I need to set black side to "pass" the turn, I tried both "0000","@@@@", but it seems that engine still give suggestion for black side, can you help me to figure out?
The engine I used is:-
NNUE evaluation using janggi-7fb17c3419dc.nnue enabled

1)position fen r2a1anbr/5k3/c6c1/n1Bp2p1p/9/9/1PP2PP1P/2N1C2C1/4K4/3A1A1NR w - - 0 10
go nodes 216
bestmove c7a10 ponder i10i9

2.1)position fen r2a1anbr/5k3/c6c1/n1Bp2p1p/9/9/1PP2PP1P/2N1C2C1/4K4/3A1A1NR w - - 0 10 moves c7a10 0000
go nodes 216
bestmove i7h7 ponder a10d8 ( i7h7 is for black side move)

2.2)position fen r2a1anbr/5k3/c6c1/n1Bp2p1p/9/9/1PP2PP1P/2N1C2C1/4K4/3A1A1NR w - - 0 10 moves c7a10
go nodes 216
bestmove i7h7 ponder e2e2 (Again, i7h7 is for black side move)

*Actually, I need white side move answer.

Hi, passing moves in UCI are currently encoded with the origin and target squares of the king, e.g., e2e2 in the starting position, similar as you would flip the king over the board to pass.
