Several comments:

1) Is he really talking about Chessmaster?

2) [ignorant question] What is a "variation board"? Is this another name for the
"Visual Thinking" window that I've never heard used before?

3) The moves in CM8000.OBK were mostly entered by hand, mostly by copying MCO.
The rest were added from a PGN file of GM games (in the same way that users can
now do in CM8000). However, if there are still moves "in the tree" (i.e.
subsequent moves in the current line) that aren't getting played, then it is
because they have a zero priority.

4) No, it hasn't YET been included in CM9000. Not sure if it IS going to be
included either.... I'll know for sure by Beta.
