in practice it is "free castling", which was used in the 17th century.
This could complicate things for the computer...
2023-12-04 14:29:56
Okay, okay, the ARB and the rest...
Now something more practical:
if we consider multiple castling as an option during the game, then it is possible, by choice:
0-0 with f1-g1, normal
0-0 with f1-h1
0-0 with e1-g1
0-0 with e1-h1
0-0 with e1-f1
0-0-0 other options...
in your opinion can the man with his strategic vision recover on the computer or would it be worse?
2023-12-03 11:30:30
I'll try to express myself better:
there is a conceptual, strategic and helpful part: the good principles, but this alone is not enough to go to heaven, also if it bring you on the "good" road.
There is an analytical, I would say "quantum" part that cannot be transcended.
2023-12-03 11:15:40
There are 4 pieces on the board and I have studied it for years, I know some things that are not in the books, but I am not able to give you a real system to solve it: in the end it is a calculation problem, it is probably just a problem of calculation.
2023-12-03 11:10:11
If I give you 10 commandments and tell you to put them into practice and go to Heaven, after a while someone might say why aren't things in the world so easy? And is the world infinitely more complex, possible, but also dark?
Is there anyone who by applying the A.R.B. can win with Rook against Queen  against Stockfish?

Fair enough

Because SF15 NNUE was/is a ground breaking version of SF :)

It was the first version to play a perfect A.R.B Chess System game to a Draw! (Which is what most people in the know think Chess is with perfect play?) When Quantum Computers evolve they will prove it one day? All symmetrical games should be Draws?

ARB, brother, why don't you update your name to SF16 NNUE Fan ? :p

Below is an update to my program version THEARBCONNECT4V7X6PROGRAM30112023

Which includes <( + { TURBO LEARN! } )> + LEARNBLOCK301123 for a massive improvement in game play :)

There is also a version showing the game improvements from version 27/11/23 playing a 100 game match against this version 30/11/23

The 100 games are also included in the .zip file to see how the game play has improved.


For anyone interested in the complexity of Connect 4 (7x6) from the Wiki article below...

One measure of complexity of the Connect Four game is the number of possible games board positions. For classic Connect Four played on a 7-column-wide, 6-row-high grid, there are 4,531,985,219,092 positions for all game boards populated with 0 to 42 pieces.

Should TCEC conduct a replay of Stockfish vs Leela just in case it was a big fluke?

No disrespect to Leela, I'm a firm believer that Stockfish winning against them is a huge fluke and robs Leela of truly accomplishing what they're capable of. I've spent the last few minutes in pure disbelief and it just doesn't make sense to me. I've spent the entire regular season watching Leela play great chess it's just not fair.

If Leela lose again I will face that Stockfish deserved the championship, but I am just 100% sure it was a fluke and does a big disservice to Leela and the Superfinal.

Below is a version of my Connect4 7x6 version,I decided to make this version so it can be played against other 7x6 programs online as there are many! and versions on Android phones etc. the 8x8 version I made at the link below is limited to the amount of online etc. programs you can play it against...

The A.R.B Connect 4 (8x8) Computer Program Challenge 2021

The program has a lot of inbuilt learning using my latest { TURBO LEARN! } and then get's even stronger the more games it plays,plus it has { RISKY+ MODE } which will play unusual lines if you get fed up being beat with the normal game play :)

Below is the C47x6 Version link...

Future proofs can be done:
of tournaments with Stockfish 16, let's say with Houdini 2 or Rybka 3, and with about ten weak engines, they play a simplified position, for example without queens or only pawns etc...
In this way we can  define trends, it is a tendency to say "Stockfish 16 is a perfect engine"; it's a tendency to say "I am me", etc...
2023-11-27 21:48:10
A future perfect engine could potentially not play strong enough to guarantee a win

but it might also do that, for example, choose the move that gives it the most advantage, even

if it's a theoretical draw. Then eventually current chess engines would make small mistakes,

put themselves into difficult positions and it's exactly at those positions that they would often

make the final mistake and lose.

But the problem is that once we have a perfect chess engine, we are going to have more than just

one. Everyone will adopt the new method and chess will be solved.

However, it seems more likely that engines will just be very strong and perhaps reach this

point where chess is not solved but it's becoming increasingly more difficult to find positions

where engines may make a game-changing mistake. Or perhaps they do small mistakes but very rarely

and so never enough to lose a game.

Perhaps we can then increase the board size, introduce new pieces and rules etc and then

we will have a chess variant that is more appropriate for engines and perhaps for humans too

because a very strong human still finds it hard to win at chess with all the preparation

with chess engines and having to find new lines etc...

But with a much more complex games, it will be much harder to study the game at such length

After some point it becomes unmanageable.

The problem is that the game becomes too messy and complicated whereas chess is like

complicated but at a kind of manageable level... at least for gms that know all the lines already..

chess960 is also a good choice for humans but I imagine that engines won't have issues with it

and perhaps even humans, it's just more lines to memorize per position and that helps a lot

with not like knowing the full game by heart...

It's just that we are used at the chess rules and we aren't so keen on changing them

and even with the draws it's still fun, it gives a different meaning to the wins.

I think chess engines are just playing really well.

To be honest it looks like a miracle to me. They actually go straight to the best moves, it's

otherwise impossible to reach such insane depth because of how possibilities explode

with each move.

Trying to implement Q* in Stockfish NNUE ...
2023-11-24 13:57:55
In that position you decide, and you will  exclude 8.0-0 but you have available:
8.d4, 8.c4!?, also 8.b4!? and in all about ten interesting moves that open up like a fan.

1. e4 e5 2. f4 exf4 3. Nf3 g5 4. Bc4 g4 5. Bxf7+ Kxf7 6. Ne5+ Ke6 7. Qxg4+ Kxe5 *
this is a 16th century analysis of Polerius.
It doesn't matter that 6...Ke8 is better or worse ,if you start from this complex position you give the game a very different character from that of the modern game, and test your engine in a position with the weak King.
You have no idea how easy it is to make mistakes here, even for an strong engine.
2023-11-23 20:03:41
As I have written below the draw is an immanent behavior of chess game. So those chess rating systems
(mainly a kind of ELo system) what can not take into account with real value of draws are a rather silly rating systems.
The first ICCF Champion who used computer (IBM) for winning the title was Berliner (1965-68)
From his time the use of computer is legal during ICCF competitions.
Now practically every ICCF player use STOCKFISH run on home PC to high-end servers.
So - opposite to the old time days the ICCF ELo and ICCF Title reflect on the power of the used
hardware and not the analysis knowledge of that players.

@All Correspondence chess masters.
I feel chess and play without calculating because I am the con-science: I am the feeling that accompanies science.
As long as I'm the chess master.

It would be better using the method of football competition:
They choose the strong players as raised and during more circles they choose from the weaker players
the other members of the groups.
In this case not only the draw could be fewer but it could be turned out what is the real value of an
ICCF titles.
You may be an ICCF GM after played 1-200 games only, what is statistically a nonsense.
2023-11-22 12:42:52
Chess is a zero-sum game. This state is not proved exactly but based on practical games it is rather
obvious. So the natural results of chess games is the draw.
Peoples often refer to the results of ICCF games presuming the CC games near "perfect" and this is the cause of the large number draw games.  
In reality there is another cause of this phenomenon:
The stupid system what is used for creating group from competitors.
From the large number of candidates they create groups with the same "ICCF Elo".
This system garantees the enormous number of draw.
2023-11-20 13:50:43
Playing perfectly and winning are not necessarily the same thing.
Or do you want to play a game with a perfect being? Do you want to play chess with God?
All you need is a draw to beat an invincible opponent.
2023-11-20 12:56:35
If the perfect chess game is a draw, the engine that plays perfectly is not the one that wins but the one that doesn't lose.
Starting from this axiom, even if it is not easy to understand if it is true, some conclusions can be drawn:
1 in the future perfect engines may not win tournaments with a set of imperfect engines or even with humans.
2 an imperfect engine might have a higher score than a perfect engine, although it cannot beat it in a head-to-head match.
I'm just trying to imagine the future...

It's pretty much established that Houdini was a SF clone.
People leaked source code that was 99% like SF8's code, except rewritten in dutch. Then this source code was compiled and matched Houdini's behaviour in nearly all test suites.

Also, this
2023-11-17 18:56:27
didn't stockfish comfortably beat Lc0 in the previous sufi?
Did LC0 use more powerful hardware for the bonus? Anyway, indeed the engines at the top are very close. Tcec will have to use increasingly more complex and one-sided openings to avoid a drawfest.
I don't know what happened to houdini, wasn't it discovered to be a stockfish clone of some short? Maybe it's author doesn't want to develop it further. Way back then it used to be the strongest chess engine in the world!
2023-11-17 11:00:42
They are on par even Stockfish is a little stronger.
Stockfish, Dragom, LC0, Berserk are the same technological culture.
However, no one has ever updated Houdini with the NNUE, why don't you do it?
Anyone have Fritz 19?
