Chess is not a sure draw for white.

Its a long time since I ever even considered tic tac toe ...
but regarding those two 'not a sure' statements -
I agree. 
And 'sure' anything might never be proven for white nor for black regarding white's 20 opening options because computers and software/programming might never be strong enough.

It also just occurred to me - that if computers eventually did affirm any kind of 'sure' from white's very first move - would humans even be able to understand whatever the computer 'proof' would be ? ...  Maybe.  .  But is it 'sure' ?  That would have to be proven too maybe.  If it could be.

You go on repeating the same statements as if we didn't read them. I said we must establish, and gave Allis' definition of "weakly solved", which is the standard (with some little variations in form, but equivalent) definition used among computer scientists. You gave your own definition, which does not define "ideal" nor "optimal" (which might be not a synonym for "best"). I hope you won't take it as an offense, because it isn't, but are you autistic, by any chance? That would explain some things.

Solving chess is a computational problem, and it falls in the field of mathematics and computer science (which are strictly related). In science "known" means "proven", otherwise we don't know; we just suppose, assume, hypotesize. If you give your own definition of everything, you can "prove" basically anything.

That White must lose a tempo to lose the game is still an assumption. Probably it would be an advantage for Black, but someone even says that Black has a compensation for being the second player, because he has more information about the opponent's plan. Besides, you said earlier that you know that the game is a draw, but now you say that most probably the tempo is insufficient to win for White. That's contradictory.

You could not "know" that Black cannot win, if not for the evaluation functions derived from our (and NN) incomplete experience of the game. And if you say I'm right, you cannot exclude to find one of those special cases among the openings you aim to cut down in the process.

You "know" many things that are not known to those who understand them better than you. For example, mathematicians certainly do not know that those two conjectures are true. Even those who believe that they are true would acknowledge uncertainty because it would be foolish to be certain.

There is no shortage in mathematics of things which are believed to be true ending up being proven false. Some of the greatest mathematicians have conjectured things which turned out to be false. An example is Leonard Euler's sum of powers conjecture -  that for all n > 2, there is no solution in natural numbers of the equation:

a_1^n + a_2^n + ... + a_(n-1)^n = b^n

(A strengthened form of "Fermat's Last Theorem" - itself a conjecture for 400 years)

Euler's sum of powers conjecture was proposed in 1769 and until 1966 there were no counterexamples.  (He had proven it for n=3 in 1760 - also the first step towards proving Fermat's Last Theorem).

After being tenable for almost 200 years, in 1966 one counterexample was discovered for n=5. In 1988 counterexamples for n=6 were added. Nothing is known about the truth of the conjecture for n > 5.

Allis solved Connect Four which wins for the player going first and his definition relates to that. Part of his solution involved strategy stealing. The definition: 'providing an ideal game with proof that all moves are optimal' is not mine, but more clearly indicates what is to be done.
The 'strategy' in the other definition, what is that for chess? I see no other that strategy = providing an ideal game with proof that all moves are optimal.
"ideal" = without mistakes
"optimal" = no other move provides a better outcome

"I hope you won't take it as an offense, because it isn't, but are you autistic, by any chance?"
++ Of course it is offensive just like those calling me 'crackpot' and other insults because they diasagree and find no valid arguments. Ad hominem arguments are used for lack of valid arguments.

"'In science "known" means "proven""
++ That is not true. Provability is a higher degree of truth. Fermat's Last Theorem and the Four Color Theorem were known to be true before it was proven and so was "Checkers is a draw". Formally these were conjectures or hypothesis.
Also Relativity, Quantum Mechanics, the Big Bang are known to be true: no experiment has ever contradicted these, but not proven.
"No number of experiments can prove me right, one experiment can prove me wrong" - Einstein

"But you cut down entire openings from the search tree because you "know" they are inferior."
++ No it is not like that. White tries to win, black tries to draw. If a candidate ideal game leads to a draw, then only white moves need retracting. If it is proven that 1 d4 Nf6 draws, then it is not necessary to establish if 1 d4 a5 draws as well or not. Likewise we can apply logic. 1...a5 does not contribute to piece development or the center like 1...Nf6. So even without calculating it is evident that if 1 d4 Nf6 fails to draw that 1 d4 a5 is then bound to fail as well. So yes, these two logical principles allow to cut down the effort by a factor of 10. We are allowed to use what we know from centuries of human play and millions of human and engine games and what has been independently rediscovered by AlphaZero with no human input except the rules. The center is more important than the edge. It is good to develop pieces into play. A tempo is worth about 1/3 of a pawn. Being 1 pawn up is enough to win. In my opinion chess is solved once a draw is proven after 1 e4 and after 1 d4. To be extra sure 1 c4 and 1 Nf3 can be calculated as well. 1 a4 or 1 Nh3 are not necessary.

"That White must lose a tempo to lose the game is still an assumption."
++ No, that is not what I wrote.  If chess were a win for black, i.e. white were in Zugzwang, then white should try to lose a tempo in order to try not to lose. If 1 e4 e5 were a win for black, then white would aim for 1 e3 e5 2 e4 not only to avoid losing, but to winning.

"someone even says that Black has a compensation for being the second player, because he has more information about the opponent's plan."
++ That is correct: the information somehow offsets the extra tempo. Even so the information not completely compensates. Black struggles to draw but succeeds.

"you know that the game is a draw, but now you say that most probably the tempo is insufficient to win for White. That's contradictory."
++ I know, but it is not yet proven. That is why I say 'most probably'.

"You could not "know" that Black cannot win, if not for the evaluation functions derived from our (and NN) incomplete experience of the game."
++ No, the calculation towards the table base gives the verdict draw / win / loss. The evaluation function cannot decide that however sophisticated it is. An engine on a desktop can play a decent game even at say 5|0 time control. The engine does that based on its evaluation function, as 5 minutes do not allow to calculate all the way through. However a cloud engine at 10^9 nodes / second (that is 1000 x faster than a desktop) and running for 5 years can calculate all the way from the opening towards the 7-men table base. It does not depend on its evaluation function.

You can't get the proof, without starting with a much stronger solution. How much stronger do you start with? You have to run quite a full, strong solution, with assessments, discarding obviously random and losing continuations, even to get an idea at which level of approximation to "principled play" you need to run your closer search. Probably 100 years of explorative analysis before you can get started, minimum.

As I have explained, several times, that is why no distinction between weak and strong solutions is possible until AFTER the event. There's no doubt about it at all and anyone who cannot understand it isn't capable of providing useful input into this question. It's such a simple thing to understand but until people do understand, this topic is a hot air generator and little else.

<<That is also the way Sveshnikov indicated.>>

It's simply because you agree with him that you cite him and not because there's any value in his pronouncements. Forget him, because his opinion is worth no more than that of anyone else.

Difficult to find but this seems to be Allis's definition. It's the one we started with and not so far from tygxc's. It's still meaningless because it requires a stronger solution to provide proof.

Weak: Provide an algorithm that secures a win for one player, or a draw for either, against any possible moves by the opponent, from the beginning of the game. That is, produce at least one complete ideal game (all moves start to end) with proof that each move is optimal for the player making it. 

If Allis didn't understand that, whoever he is, his opinion is worthless. If he understood it, his definition is hypothetical only. If you can refute it, you're cleverer than I am. happy.png

Avatar of Elroch

A "weak" solution requires the exhibition of practical optimal strategies for _both_ sides plus the reasoning that shows that these strategies are optimal (as achieved for checkers). The only time one of these strategies is trivial is if the other side has a winning strategy.

A valid weak solution proves what the value of the game is and a practical way to achieve this value with either side.

Allis is the mathematician who solved ''Connect Four''.
I agree with

"Provide an algorithm that secures a win for one player, or a draw for either, against any possible moves by the opponent, from the beginning of the game. That is, produce at least one complete ideal game (all moves start to end) with proof that each move is optimal for the player making it."

In case of chess that would be: 

"Provide an algorithm that secures a draw for black, against any possible moves by the opponent, from the beginning of the game."

What is an algorithm in this context? There are games like Nim with a simple algorithm. Part of the Connect Four proof was also strategy stealing: put a stone on the same column.
It is still unclear what 'algorithm' precisely means in this definition.

That is why I prefer the second wording:

"produce at least one complete ideal game (all moves start to end) with proof that each move is optimal for the player making it."

complete = from initial position to draw/win/loss
ideal = with no mistake i.e. with optimal moves i.e. a tautology, the word 'ideal' could be striken as the 'optimal' already implies that.
optimal = no other move produces a better outcome

There is a massive distinction in time & storage between solving strongly (10^36 positions) and solving weakly (10^17 positions).
The proof that the moves of the 'ideal' game are 'optimal' follows from exhausting the possibilities: from showing that none of the reasonable alternative white moves leads to a win.

Example of what passes for reasoning by @tygx

Checkers was solved with complexity about the square root of the number of legal positions and losing chess was solved with complexity about the fourth root of the number of legal positions, therefore (from this sample of 2) all games can be solved with about the square root of the number of legal positions, including chess.

The number of legal chess positions without promotion is circa 10^37, so since promotion is never "sensible" we can use the square root of this this number.

Therefore Elvis lives.

My words, but honestly representing the "reasoning".

Avatar of tygxc

#1478
Well Mr. mathematician, can you come up with a better estimate and provide evidence?
Each pawn move and each capture render huge numbers of positions inaccessible.
Thus the number of positions to visit for a weak solution must be lower than the number of legal and sensible positions.
Checkers like chess is a draw. The rules differ from chess. Square root.
Losing chess unlike chess is a win. The rules are similar to chess. Fourth root.
Hence it is plausible that for chess it is about the square root too.

Promotion is sensible, but it is usually to a piece already captured and usually to a queen.
Multiple excess underpromotions are not sensible.
For each sensible position with 4 queens excluded from 10^37 there are several non sensible positions included in the 10^37, so the 10^37 is an overestimate.

Therefore, a weak solution is not possible, without a semi-strong solution first. Without that, these definitions are totally meaningless.

As I have explained, so address it, please. I don't care about authoritative sources. I have no idea if some "authoritative source" has managed to con the entire academic establishment. If you (or anyone) can't think for yourself and provide good reasoning, then you may as well continue to talk among yourselves, because we're getting absolutely nowhere if you don't understand the procedure necessary to establish a weak solution. That definition is completely empty. It actually consists of incomplete Boolean algebra. Now doesn't it!? happy.png

Autistic minds work in a different way. It does not mean an autistic person is wrong or inferior. I said that, because it seems that all posters here have difficulties communicating with you. One asks: "what do you mean by that?" and you repeat the exact same thing with the same words. You have done this so many times and that's unusual. You give your own definitions and opinions (or just another person's) as if they were absolute, totally neglecting what others here and specialists think about those definitions and opinions. And this behavior is restricted only to this "5 years to solve chess" topic, for apparently no reason; you do not behave like this in other threads with different topics. You said that you will hold to your position until others will prove you wrong, but none has understood what kind of proof you would accept.

Since you did not answer the question, I will act as if the answer was yes, but only to try to find another way to talk to you, if possible.

In fact, they are not proven, that's why we still call them "theories". We use them because they provide the best predictions and are not yet contradicted (indeed, quantum entanglement seems to contradict relativity). Do phycisist know they are true? Idk, never heard them say that. If scientists know that a theory is true, how could they abandon it, if falsified (as it happened to Galilean relativity an classical mechanics)?

Right! Some theories can be proven, other not. If we solve chess in 5 years, then it is proven it is feasible; and we could discover a solid POC that it is feasible in 5 years, because it is mostly a mathematical problem; but our knowledge of the universe is incomplete, so tomorrow we could discover a new phenomenon, which contradicts relativity for example, as electromagnetism led physicists to abandon Galilean relativity.

There's a difference between draughts and chess. The former is extemely simple in comparison. A bit like solving naughts and crosses! i.e. "checkers has been weakly solved, therefore chess". Or "I can jump over a three foot hedge; therefore I can jump onto the moon."
