Neither. In this program, the only option is to choose "Difficulty Level" which I had set and always keep at the most difficult level of 10. The other levels are too weak to be of much interest.
I also enjoy playing around with other strategy games like "Starcraft" by finetuning particular scenarios and observing the A.I.'s response.
Part of the fun I have with computer chess games is learning their strategy quirks and then playing around with them. This can lead to unusual positions as I show in the image.
I have labeled this one "Positional Advantage - White". (from preloaded pc game "Chess Titans" @ lvl 10)
