Stockfish evaluation at depth 50 on all possible initial opening moves

 Actually, +191 Elo is enough to reduce draw rate below 50% under any circumstances... And +50 Elo is enough to win tournaments smoothly... That's why we always see the same faces in top human tournaments.

Yup. 1. d4 wins almost 100% of the time!!!

That is all interesting, but it hardly helps humans play.  Knowing that Stockfish recommends 1. Nf3 doesn't tell you much about how to proceed in trillions possible variations, and memorizing those variations is simply impossible for a human at our current stage of evolution.

Very interesting thread! (To me, at least.) Somehow I missed this thread when it first appeared.

Database dump

Of course Stockfish vs. Stockfish is 95% draws...it's an engine playing itself.  Both sides evaluate the positions almost identically, and when developing, I can guarantee you that if the results are not mostly draws, the team will tweak the engine until it is playing mostly draws, because winning championships is about not losing first, winning second.  You can draw 50 games for every win and still be champ.  So tuning an engine to play like Tal is counter productive, because aggressive chess that wins via applying lots of pressure and forcing an error doesn't do diddly to a an engine.

Hard to read what their site is talking about through the Google translation. Something about a DB of 4 million positions wrapped in some of their proprietary nonsense. If you want a free position DB without all the hubub, Lichess has 28 million analyzed games for download, from which you could probably scrape tens of millions of analyzed positions.

So according to this 1. f4 is better than 1. Nc3 ?

Somehow I'm not convinced...

WOW!

Ok, Nf3 gives +0.17 advantage, chess has been solved! 😒😒😒

Latest stockfish still see 1. Nf3 as best move (according to analysis.sesse website).

Latest Stockfish has contempt 40, so +0.62 means= +0.22. 

best move is 1.c4 according to Alpha Zero and let's face it..... He's the God of the Modem Chess World

Alpha Zero is estimated as 3774 rating only. Latest Stockfish on 64 CPU is 3851+ rating.

For what it's worth, here's a wiki that's devoted to this sort of thing:

Your reference never reach depth 50, i see about 17 to 25 only (which is extremely shallow and unreliably weak ) . As you might know, the strength of computer analysis is highly dependent on depth or number of nodes search.

I expect depth 50 analysis of Stockfish is probably (3700 elo) and depth 17 analysis is probably (2700 elo.).About 1000 elo strength gap.

Here it is. ( Keep in mind , Stockfish evalues between +0.5 to -0.5 in opening are generally perfectly playable.

Why is 1. Nf3 considered the best move?

This is the static evaluation table of static position. Put any pgn or Fen into that search box and stockfish will evaluate static.

Why best? Cos SF consider the end of PV better than other moves.
