ok...so -

1. e4 e5

2. Ba6 NxB (for example)

and now what ??...ur saying that w/ best play...

I let SF16.1 play the position as White and it already has overcome being dn a bishop.

so...its playing u ?? only cuz ur no representation of a wc silicon player lol !...plz. trust me. this is a lost position in 3500 chess.

ohh !...and btw ? 3...d5 is the dummest move ive ever seen.

No, it's playing a silicon player (which may be a representation of a wc).

But my method of proof is exactly the same as @tygxc has posted several times purporting to prove the opposite.

Fact is nobody knows.

We're not interested in 3500 chess, only perfect chess. This is all 3500 chess can do with a simple mate in 52 against crap opposition.

If you click on the magnifying glass you may find the analysis rates it top after a couple of minutes (but that's no proof of anything).

I can't imagine that chess will never be solved. The whole move space is finite and computing power as well as computing technology will continue to advance.

BTW who says the number of chess positions is bigger than the atoms of the universe? Isn't this complete BS?? Can somebody elaborate on that? The universe is constantly expanding while a chess board stays within its 64 squares. This alone is enough to abandon the theory that chess can never be solved.

Observable universe - versus 'universe'.
Those are different.
Nobody will ever prove that the universe is finite nor infinite.
Whether in size or in age or in mass.
'universe expanding' is mispremised.
How can an infinitely large object expand?
What does it expand into?
----------------------------------
the Big Bang and 'universe' are constantly confused.
Will anybody ever prove there are or aren't other Big Bangs out there - elsewhere and elsewhen - past present future ?
If you're going to have a cosmic egg 'explode' then how do you arbitrate there'd be just one of them?
'There can be only One' is a human subjective tendency that was even exploited in a famous movie.
Humanity's narcissism ... 'the only Big Bang that could be is the One that We are in.'
Its related to geocentrism. An extremely false notion.
However there's lots of real redshift evidence there really was and is a Big Bang in our locale. Thereby allowing earth to exist.
But that doesn't mean the Big Bang is 'the universe'.

Not me doing the analysis, tell SF16.1 - it shows 3...d5 top at depth 31.

Perhaps youl'd like to post your version playing Black v SF16.1?

Avatar of playerafar

e4 d5 is considered to be OK for black.
The 'center counter'.
Although several other replies to e4 are more popular.
But c4 d5 isn't even considered to be an opening apparently.
After cd Qxd5 is black 'lost'?
No. But its considered to be much worse than the Center Counter.
Should c4 d5 be 'dismissed' as a reply to c4 ... ?
It can't be - for computer 'solving' purposes.
Because of something called 'objectivity in mathematics'.

if u feel that 2. Ba6 could prove to be valid ?...then u needta self-check into the white jacket hotel. either that or go getchur brains tucked back in - way too open-minded.

they can fight their own fights. they dont need u. besides ur justa llama short on oxygen to ur brain...from high places - way WAY out there lol !

If you're saying you know whether the position after 1.e4 e5 is a White win, a draw or a Black win, I don't believe you. If it's a Black win then 2.Ba6 is a perfect move.

Avatar of Thee_Ghostess_Lola

The move 2. Ba6 after 1. e4 e5 is quite unusual and not considered a standard opening in chess. Typically, the bishop move to a6 doesn’t contribute to White’s development or control of the center. In fact, it allows Black to gain a significant advantage by capturing the bishop with either 2…Nxa6 or 2…bxa6.

u can see this AI response on the 1st page of "chess for dopey dopey doo's". or just play antichess...be my guest. at will.

btw copilot could beat any chess dunce (like me) thats following this thread.

Demonstrably false. I let SF16.1 play the position as White and it already has overcome being dn a bishop. 

And engines can validly use only transpositions of nodes, not @tygxc's positions under competition rules, to avoid recalculating. There aren't too many of those.

I haven't yet identified a source to indicate that Stockfish does include 50 move info in the hashed positions. The chess programming wiki page on Zobrist hashing has no reference to storing information relating to the rule.

Note that the legal paths from a position with a different move count are exactly the same except when a 50 move draw is reached. I was wondering if this would permit some sort of efficient reuse. All paths that reset before the 50 move draw are common. I have not delved into the details much - I was hoping to find some source explaining what is done.

You're falling into the same trap as @tygxc. You're failing to take account of whether it's Cheddar, Stilton or Red Leicester.

Any forced capture game is going to be an easy solve comparatively. This is obvious, the game tree is miniscule.

Certainly helps to keep the branching factor down.

It would need to store 9.2.2 positions for previous positions with the same material to validly reuse an analysis. The ply count is apparently taken into account in the static evaluations (not always to best effect).

Note that the legal paths from a position with a different move count are exactly the same except when a 50 move draw is reached.

Not necessarily unless the 9.2.2 positions are included in the stored positions as above.

"50 move info in the hashed positions"
++ None of the ICCF WC Finals draws end by the 50-moves rule.
An average ICCF WC Finals draw lasts 39 moves.
Those games are 99.992% certain to be perfect games with optimal play by both sides.
