Sorry if this is silly, but I'm just getting back into chess and I bought Chessmaster 10th Edition on the cheap just to have some guidance.
My question is about using the Game Analysis function. What does Score mean? It's usually followed by a number like .81 or whatever. Also there's a Depth fraction, like 1/10 or 2/9. What do these mean?
The Game Analysis also tells me my worst move, which looks like this: Worst move: 2, f5, Decrease: 99.14
Do these numbers mean much?
Note that I lost this game on purpose just to get some data to show. Thanks in advance.
