I have implemented Chinese Chess. The reason why I made this implementation is because the Chinese Chess on the Zillions CD plays badly. I also added a more Western style piece set. The reason why it plays badly is because the pieces are incorrectly evaluated. For instance, the Cannon is regarded as equally valuable as a Chariot. This is clearly wrong. All I did in this implementation was to apply tweaking to alter the relative values of the pieces. I don't know if the values are ideal but they clearly improve play. I tested my version against the version on the Zillions CD on a 1.6 GHz computer, at 15 sec per move. The colours were alterated and the openings went differently in each game. My version won six games out of six. This proves that's it's often necessary to apply tweaking when programming Zillions. Note that I did this also with today's published games, Commodore Chess and Brigadier Chess. Zillions overestimates pieces with cannon moves. The Chinese Chess zrf will be published next week or you can download it already now.
