a lot of ppl are complaining about how random the chess is (who can blame them) but heres the trick
you gotta have interact on left click toggled on (f10-interface/controls bottom) and simply talk to your king and left click on the unit near his proximity u want to control(if that unit happens to be out of range leave the king and talk to the piece thats near the ones u wanna move,alternatively i exit the king,talk to a footman and just move all of em forward)
P.S. for paladins,blessing of protection and the divine bubble removes the 10sec debuff
thats all
