Computer analysis for free members is not so strong, so you might want to check it with the engine(there are several free engines available).
-1,02 means that computer evaluates that black has advantage approximately 1 pawn in value.
Positive number - white has advantage
Negative number - black has advantage
I just received free computer analysis of the game I drew recently. And it's wrong! It shows some dubious moves on my part which I think were ok. It doesn't show any mistakes on my opponents part and a game ended draw when I was playing black!
So to summarize: I made 6 mistakes playing black, my opponent made zero and I still managed a draw
.
Something's seriously wrong wih this feature.
And here's how it end it's analysis:
'Black has moderate advantage' - that's how it ends its analysis.
Geeeeeez
