Thanks! Not a lot is different with new pieces for the bots as they basically only look at what moves a piece can make, but I did have to give each one a value. For the variants it was a bit trickier, for king of the hill I made the bots value getting closer to a hill with their king. In the variant where pieces die when they capture the bots just count that as both pieces being captured, and in fog of war it really just cheats but I made sure to use the easiest bot in at least the first fog of war level.
