Lordi: When I first began to play XiangQi I asked the question about enough material to win- and a much more experienced player told me that the basic rule is that to win I would need one more attacking piece than my opponent had defenders. I have found that it works a s a rule of thumb. My king of course is always an attacking piece.
kleineme: Is it possible to change the software program so that perpetual check and perpetual chase would not be allowed? It would certainly improve the program and make for a better playing experience for everyone.
