# How to read analysis by engine

Hello dear all

How are days? Anyway, I am interested to know how to read the analysis by droidfish (android version of stockfish). Say for example, after I play 1.e4 e5 2. Nf3 Nc6 3.Bb5 the analysis panel shows-

[23] <= 0.18 Nf6 (and few other moves)
d: 23 1: Nf6 t: 422.70 n: 51264k nps: 121k
Book: a6: 51 Nf6: 31 d6:19

Thank you

[23] is the depth/ply of the calculation

= says the position is considered equal in that position at that depth.

d:23 also depth

1: Nf6, is suggesting Nf6 as the top rated move, I think.

t: time spent on the analysis

n: number of node the engine searched through

nps: nodes per second

Book: the most common replies from that position in the engine's opening book. a6 occurs 51 times, Nf6 31 and d6 19 (all within the opening book being used).

And 0.18 is the score, right? In the same scale in which a pawn is 1, knight is 3 etc.?

0.18 is 2/10 of a pawn advantage to white

is droid version of stockfish free?

Nei, 9/50.

Hehe

thank you all for all the nice efforts

[23] <= 0.18 Nf6 (and few other moves)

< Does this symbol (<) means that  the move is analysed to less than 23 nodes in this analysis?

A positive score is an advantage for white an a negative one is an advantage for black.

Oh, thank you. I didn't know that.

And it's also possible to customize it on settings that allows you to choose whether the score is always from the white's perspective.
