Whatever is current - Amazing Leela

Common sense tells us that 1. e4 e5 2. Nf3 Nc6 3. Bc4 is a draw with correct play.

1. f3 e5 2. Kf2 is also a draw with correct play. What matters is when theory ends and a novelty is played forcing you to think, what side of the board would you rather play. The "true score" would be positive if you'd pick white, and negative if you'd pick black. There's an objective best choice, and the position being a tablebase draw (correct play?) is irrelevant, because we don't have 32men tbs.

The "objective" best choice depends at least on the time control and the "temperament" and skill of the players/engines. You seem focused on engine/engine matches at 12+2 on a certain game server.

Winning a pawn increase significantly my chances to win against other human opponents.

What if the best line for black includes sacrificing a pawn, and both exchanges (you keep the Bishop pair, so it's knights for rooks), so you end with huge material deficit in a position you have no idea how to continue? That's the kind of stuff I'm seeing, if GMs hire people to keep them up to date about latest opening theory, and you don't see these lines at top level play, it's because these lines are useless at the human level, because they're way too complex and it's hard to know what's going on (even engines get confused.) Top GMs are best playing into positions that they know how to play, and it wouldn't matter to them how Stockfish or Leela plays them. The best positions against engines are not the same as against humans.

If you do not know how to continue with black then you can prepare at home by memorizing lines that the computer beat you and you can use one of them to beat your human oppoent OTB.

Even if your opponent does not choose one of the lines you memorized then the lines you remember may give you ideas how to continue.
