[PC][late 90s-early 2000s]Chess influenced medieval puzzle game

Each level was on a chessboard in a room in a tower/castle, you vs AI. You had medieval units with different move sets but it wasn't strictly chess. Can't remember level win conditions, maybe just defeat all enemy units? Get to the other side? Idk

I remember the rooms would often be dilapidated, with debris and missing floor to make the board more complicated.

It had fairly realistic graphics, not stylized I mean. Can't remember if 2d or 3d. Fixed top-down perspective.

It's been bugging me for so long! Thanks in advance!
