Nakamura vs Stockfish, public match 8/23

[Dan Astrachan]

Out of curiosity, how does the operator who will move the pieces for SF decide when to make the move? Is it left to their own choice (they make the move whenever they think it's appropriate) or does the engine send some sort of specific instruction (like "I'm done thinking, play this move now.")?

I make the move on the board whenever Stockfish makes its move on the computer, so I have no say in when the move gets made. I program in the time control of the game, and Stockfish makes its moves accordingly. (Actually, I give it a 22 second increment instead of 30 seconds, just to account for the amount of time it takes me to enter the opponent's move into the computer and the time it takes me to make the computer's move on the board.)

[Dr.Wael Deeb]

But yet again,this is not a classic game of chess....

It's some kind of a mutation and it does not prove anything....

To go a little bit further,it's actually an ugly variation of chess....
Dr.D

The answer is clear - if the games would be chess960 then that would be a huge improvement
.

Actually that is a good idea.

I prefer Chess 960 any day over the abomination called material odd chess....

Even if Naka hold a draw or even win one game with no a7,b7,c7,d7,e7,f7,g7 or h7,then what

What does that accomplishment prove

Nada....

If you tell a first grader who's is familiar with the chess game rules that some strong GM won a game against a super powerful computer with the white pieces while the computer's e7 pawn was missing from the chess board,he'd probably laugh at yuor face right away regards,

[Uri Blass]

One month after the very entertaining match between GM Naroditsky + Rybka and Stockfish (described here by Naroditsky: http://www.chess.com/article/view/how-r ... -the-world), we will be hosting another match with the best chess player in the United States: Hikaru Nakamura (FIDE 2787 Elo, and a remarkable 2906 Elo at Blitz).

The format will be similar, but not exactly the same. The first two games will be the same as the previous match: Nakamura will be able to use Rybka 3 on a 2008 MacBook to analyze moves in a 45'/30" match against the latest build of Stockfish on a current 8-core Mac Pro. Each side will play as white once, and Stockfish will have no opening book (and no tablebases).

For the last two games, Nakamura will play by himself (no help from Rybka), but he will have move-and-pawn odds against Stockfish. Specifically, he will play as white both games, and Stockfish will play black with one pawn removed. The pawn to be removed will be selected at random by rolling an 8-sided die before each of the two games. The time control will be the same as the first two games.

The actual games will be played on a physical chess board; I'll be making the moves on behalf of Stockfish.

We will be broadcasting the games live on chess.com, but we'd also like to invite any of you to attend the match in person, where you'll be able to see real-time mirrored feeds from both of the two computers, watch Nakamura play live, and interact with him and other chess fans.

The event is next Saturday (August 23) in Hillsborough, California (just a bit south of San Francisco). If you'd like to come, please RSVP here:

https://www.facebook.com/events/312975918877354/

We'll have complimentary snacks, lunch, and drinks.

In the meantime, feel free to vote on who you think will win the match!

Thank you again... !

I have no patience to the final results of this interesting duel...

Btw,
If Nakamura will use a very well-optimized strong book for Rybka 3,
Then I expect to see almost equal performance ...

To be honest (in case of serious matches),
Engines should not be tested without pawns or without books,
because (depending on speed hardware, hashtable size, time control etc..) they are repeating and playing almost same games...
and a good memorized GM can remember the previous played games and of course later can make draws even against top engines



Keep up he good work,
Sedat

He dosen't have to be a GM Sedat ....

A 30-40 games against the chess engine making the same moves will be more than enough for a guy like you or me to hold the silicon beast to a draw
Dr.D

Is is based on experience?
I did not try it and I do not find it interesting to try it to see if I can get a draw by that way.

It is clear that stockfish with 8 cores is also not deterministic and may choose different moves in different games so it is possible that the number of lines that I need to memorize to get a draw is too big for my memory.

To be honest with you Uri,I didn't try it but I'm pretty much sure it's achievable....

Stockfish,or any chess engine for that matter that doesn't benifit from a learting feature,using one core will produce the same moves over and over again....

The MP version however will not be deterministic as you mentioned above the variety of moves will expand at a staggeraing rates....

I would prefer to see a time odds match also.

+1

I might more enjoy Nakamura vs. Chess Tiger 2007.1, or some other antique, playing straight up without any kind of assistance or handicap at all. Otherwise, what's next? Two pawn handicaps - or a knight, maybe? Actually, what I really want to see is a top GM (like Nakamura) play a ten game match against one of the top three with no handicap. Why not? Because the GM will lose? We know (or think we know) that going in. But I'd really like to see this apparent 300-500 (?) elo disparity demonstrated OTB, in normal chess. NOT Chess 960, because I think that further favors the engine.

But like others I'm pleased these matches are happening and will be watching Saturday.

CT 2007 or some other speculative enigne would be much more exciting and straight up chess, no variations. Maybe Deep Junior 13,Virtruvius 1.11_HEM or Chiron 2.0?

[reflectionofpower]

I was just perusing these games with Vitruvius 1.11_HEM and it found mistakes on winner & loser's end. The programs & hardware of today cannot be matched against. They are stronger than humans.

[Sedat Canbaz]

It is clear that stockfish with 8 cores is also not deterministic and may choose different moves in different games so it is possible that the number of lines that I need to memorize to get a draw is too big for my memory.

Dear Uri,

Actually this issue is not so hard as it looks

There is a possibility to be beat many top engines (in case of handicapped games e.g without pawn) and I will try to explain you:


For examples,
A human chess player (2700 Elo above) with a good memory can learn from the top engines
I mean, human can train (learn,copy...from the ideas of the top chess engines) in his own private testings
And it is not required to memory the full played pgn database, but it is very important to memory the first 10-20 moves
In other words, when GM will get the advantage ...then the game is over !!
Note also that even in MP testing and at slow time controls, the Top engines do not prefer a lot of various moves up to 15-20 moves

Simply what is needed:
To momory the first 15-20 moves (totaly minus plus 40-50 moves in case of diffrent playing moves)...
And then any strong human player have big chances to draw and even to beat many top engines (including Stockfish)

But under SCCT conditions (My Challenge) is very very very hard...
SCCT Authors participate always with new decent updated strong books ...that's why we can't see any GM )

[Uri Blass]

I was just perusing these games with Vitruvius 1.11_HEM and it found mistakes on winner & loser's end. The programs & hardware of today cannot be matched against. They are stronger than humans.

No surprise.
When you choose games when you know that there was a mistake(otherwise the result is a draw) you find mistakes.

I agree that chess engines are stronger than humans but analyzing human games by engines is no proof for it espacially when the humans have no motivation to play in anti-computer style against humans and did not try to get a position that the computer does not understand.
