Interpeting Chess Engine Analysis

Post by gatoruss »

I apologize if this is not the correct forum within which to make this post - it that's the case please let me know.

I have been using SCID VS PC to learn about analyzing my games. The engine used is Stockfish. I am having trouble figuring out the meanings of some of the annotations produced by Stockfish. Below is a link to a screen shot of the annotation produced by Stockfish - what do the lines highlighted in yellow and green mean? I know (or I think) they indicate who's ahead - white if positive, black is negative. But why are there several numbers?

P.S. -- I cannot figure out how to embed or upload the image.

Stockfish delivers for every principal variation of your MultiPV the evaluation in centipawn and based on the NNUE the win/draw/loss probability in per mill.

This is an example for MultiPV = 3 after 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6:
