Is it possible Alpha Zero will eventually solve chess?

No, it can't. Even if you had it train on a zillion self-playing games and it miraculously achieved perfect play somehow, we would have no way of proving that it had achieved perfect play without ...

Is chess a solved game?

Because of the observation you make, that the tree of possible game paths for chess is finite, chess is indeed solvable in exactly the same sense that tic-tac-toe is. So optimal strategies for chess ...

Is there a mathematical theorem that you can use to win a chess endgame?

Unfortunately the (original) question was a bit ambiguous and arguably still is. I try to sort the different interpretations out: Chess fulfils all requirements of "standard" game theory (...

Is there a mathematical theorem that you can use to win a chess endgame?

Such a theorem doesn't exist. The closest is the strategy-stealing argument that can be used to show that for many games, the second player does not have a winning strategy. The gist of the argument ...

What is the deepest Stockfish evaluation of the standard initial position that has ever been done?

Don't for one minute imagine that Stockfish has analysed all lines out to 30 plies (yes, that's plies, not moves). It has analysed some lines up to 30 plies, but most lines have been discarded well ...

Chess hasn't been solved and it won't be in the next decades (barring ridiculous computing advancement involving quantum computing or such drastic changes). You can calculate in your head for the ...

How to weakly solve Tiger Hunt, Atlantis Chess and Peasants' Revolt

Even without a computer one can prove that "Tiger Hunt" (a.k.a. Maharajah Chess) is a forced win. Certainly the "tiger" can't hope for more than a draw if White starts with 1 Na3 and then repeats with ...

Is it possible Alpha Zero will eventually solve chess?

Nope. AlphaZero's entire architecture (and the architectures of most other engines) is such that it cannot "find a solution", and in any case, if a solution was to be found it would be ...

What is the solution to single-check chess?

If you trust Stockfish's evaluation on lichess.org, using the "three check" variant where both sides already have two checks, White wins in 5 moves with 1. e4, 1. e3, 1. Nc3, or 1. Na3, and ...

Is it possible Alpha Zero will eventually solve chess?

No, it is impossible, even for Alpha Zero. Solving chess in a scientific sense means to prove the value of every possible move in every possible position. Without a mathematic model still to be found, ...

What do you think will happen when chess gets solved?

Probably not much. As some top players have stated, we're close to the limit of what humans can memorize to prepare for a chess game. Preparation will become slightly more refined, but that will only ...

Another point is that the chess game is finite but only with the 75 move rule (the game is drawn if there are no captures or pawn moves for 75 moves). Before, this the rule with draw by consecutive ...
