我想使用 xskak 循环添加不同的可能性来继续游戏。我使用了以下代码，该代码在每种可能性中从头开始游戏，而不是从原始游戏的最后一步继续。如何做到这一点？

您可以使用键 initmoveid 和 stopmoveid 来限制循环。
您还可以使用另一个 fen 和 moveid 开始新游戏。

答案2
我想到了一个主意，使用 setfen 来存储游戏的最后位置，然后 restorefen 并添加新的可能性。对其他每种可能性都重复此操作。我使用了以下代码：
\chessboard[setfen=,storefen=XX]
\newchessgame[restorefen=XX]
\hidemoves{1.hxg3 Ne2#}
