Learning to use all of the features of CM XI
Is there some sort of tutorial for me to learn to use all of the features of CM XI?
Also, is there a way for me to play against another person (in person) ?
While not all features are documented, a good start would be to read through the User Manual. If you're left wondering about something, then just post a question to the forum.
Online Play (as well as the Correspondence Chess feature) was discontinued in March 2012. However, you can still use the LAN Play feature. To do this, both players have to be using Chessmaster Grandmaster Edition over the same local network.
