[Variant] Faceoff Chess

[Rechefiltr-is-Fire]

This request was posted earlier in the forum, but there it’s more visible and possible to activate some efforts. This is also posted on Chess Variant Pages (but not yet approved).
Rule is borrowed from Xiangqi and accelerated for Chess. All diff from FIDE is that Kings cannot face each other orthogonally or diagonally without pieces between; however this rule changes the game, especially endgame, because King vs. King + 2 Knights position isn’t a draw.

Thank for you the game suggestion, as mentioned in (fairy-stockfish/Fairy-Stockfish#671) it might be possible to support this using the varaints.ini file, however given this game is untested, we unfortunately wont be spending any time to support it right now. We are currently spending our time on adding the more popular games first and then branching out with alternatives. We have added this game to our list and will consider it in the future.
