What do you mean by 'solving a PGN'? It refuses to lodad the game? It complains about illegal moves? And how did you use Sjaak II anyway? As engine in the WinBoard GUI, or in stand-alone mode?

sorry. I want to say: the Xiangqi engine Sjaakii is more powerful than maxqi, hoixiangqi, but it still can't give the right (or "the best") moves for the FEN position. now It may play many steps, and then give a DRAW result (in fact, should be "1-0, Red Win")

it just a funny sample, but not a bug.

I think that, if I want to win the sjaakii engine, where is "the Achilles' Heel"?

by the way, how about your haqikid ? years ago I got an amd64 version from you, but it works unstably. Now my OS is Debian 11.7 amd64, XBoard 4.9.1 (updated from Debian 10 amd64).

Sjaak II is not very strong; it is a general multi-vatriant engine, so it does not contain any Xiangqi-specific evaluation. MaxQi is a toy engine derived from micro-Max, which counts only ~100 lines of C code, so it is not surprising that it is very weak.

I have not worked on HaQiKi D for ages.
