Can anyone tell me how to "Set up a Position" in Chessmaster XI. I use this feature in 9000 and 10th edition, but I cannot find this feature in XI.

From the Main Menu, click on the middle button. The button will grow, and you'll see several icons.

Hover over each icon; you'll see a tip on what each one does. The fourth icon from the left (the one that looks a bit like a chessboard) is the one you want to choose in order to set up a position.

The board and pieces will be displayed, as well as the 'Set Up Board Position' menu. From there, everything should be easy.

Hope this helps.
