Hi there. Can anyone help me. What do the numbers that are usually found in computer notations mean, i.e. = (0.13) 17. ... Nxd5 In the example above, my question is with the meaning of (0.13). I'm pretty much self taught, so I'm afraid if this is taught somewhere, I didn't have the luxury of learning it. Thanks!

Thanks! That was very helpful.

These computer evaluations are usually expressed in so called "pawn units." That means, 0.13 represents a value of 13% of a pawn. That eval is taken from the last position of the main variant, the computer currently expects. In ChessBase (Fritz) programs and CB. engines, the eval is always from White's viewpoint -- > positive values mean a white, and negative values a black advantage. There are some engines and programs though, which give the evaluation from the progs viewpoint (especially very old chess software typically does this). There are values defined, when Fritz changes the commentary symbol (=, +/= etc.). I couldn't find a table of these now, but after some fiddling about I think that +/= starts at 0.30, +/- at 0.70 and +- at 1.40. (For my taste, the value for +- could be somewhat higher.)
