I have read the explanation of the Lc0 output on https://github.com/LeelaChessZero/lc0/w ... Chess-Zero
but I still do not understand it or I do not know how to get the most from it. As an example of the challenge I am facing see the below output from Arena. Why is Be2 the move that Lc0 selects? It is neither the one with the highest P nor Q nor Q+U nor V value.

Hamster, please excuse this lc0 newbie question: What is the meaning of "P", "Q", "Q+U", & "V"?

Do you mean it played Be2 after the screenshot?
It looks to me that it does have the highest Q+U, as well as the highest N, but the only one the list of moves is in order for is N (visits).
I don't know what the "(+7)" in the top line means or the "(712)".
You are right, Q+U is actually the highest.
If Lc0 chooses the move with the most visits what would be a useful interpretation of the other variables?
E.g. why not choose the average expected value of all playouts for a move (Q)?
Zulli:
Do you know the meaning of these terms: "P", "Q", "Q+U", & "V"?
I am guessing that V = visits. But, as pointed out, Be2 does not have the highest V value of all the moves shown. Or does the lc0 site have an explanation of the parameters, since when I searched here for "visits", it gave me no new information.
