Kibitzer's Corner
Jul-28-05  MarvinTsai: I think this game is great. Human strateically choose closed position, and got a chance winning. But the questionable 48. Rh8 let computer think for about 16-depth deep, advance his pawn, and get positional advantage.
Jul-28-05  djmercury: <MarvinTsai: I think this game is great> Agree!! Amazing march of white c pawn.
Aug-02-05  ajile: After 20..a5 I believe Black has a huge advantage against the computer. A closed position with a nice space advantage on the K-side. Black's 21..g4? is premature and way too soon. Black can just wait and prepare his break on the K-side when he is ready. First step is to run his king to the Q-side. Then build up pieces (rooks,queen, Knights etc.)on the G or H files. He can then break it open at his leisure when the time is right. At the most White should be happy with a draw here. Black worked very hard to get this ideal closed position where he can choose the break. Then he wastes it all by playing G4 too early.
Aug-02-05  Shams: <ajile> great analysis, but I think 34...h2? is the bigger mistake. White had good chances for a long while.
Aug-02-05  fgh: This is one of those games when you realize that computers are only better because of some stupid tactics.
Aug-02-05  ajile: I agree h2 is also horrible. Notice Black's King is still on the g file and look where Black's other rook still is. A8. Black doesn't have to rush. He has a clear positional advantage that will never go away. I'm guessing in the near future programmers will program the computers to recognize when locked positions are imminent and avoid them. Allowing F4 by Black was a huge White mistake for example.
Aug-03-05  Shams: <ajile> sure, but the moves we've singled out are counter-examples. the locking 20...a5 is great for black, but the locking 34...h2 is awful. Getting the program to recognize the difference is the whole ball game.
Feb-13-06  MoranCho: After all I've done...still just
hateful vindiction...it's outrageous!

Could anybody identify the 'teach me
O genius' moron?

He's a malicious, hateful individual, and worthless as a Chessplayer (and he knows it.).

Sep-26-12  Garech: Great effort by Palermo; he must have been unlucky to miss a win here. I think it's even worthy of GOTD - will try and think something up.

-Garech

Jan-02-24  Garcia Palermo: Yes, it was a pity....I did not see 49 f4, already short of time. There is an article about this game in some English newspaper, Jon Speelman comments, I think. Can anybody help me to find it? Happy New Year to everybody!
Jan-02-24  Garcia Palermo: thanks everybody for the remarks to my game!

  offramp: I was wondering about all the engines that disappeared from our world.

What happened to Mephisto? I used to play that board/set in a London department store.

Gandalf has gone. Shredder has gone. Rybka went suddenly down the toilet. AlphaZero is not commercially available; it probably gave up chess to mine bitcoins.

The best-known engines now seem to be Fritz and Stockfish.

I often have a look at TCEC, which is always interesting. It's the chess version of <RobotWars>.

Sep-07-24  Muttley101: <offramp> if you're unaware of the story of Rybka, the ICCA (or whatever they are/were called), claimed that Rybka contained large sections of code copied from Oakfoam, and banned it from computer chess competitions. If I recall correctly, Chessbase took on the developers and incorporated Rybka's techniques into Fritz.

The DCNN that underpins Alphazero was bought by Google and is being used to investigate all sorts of research problems, for example: drug design, protein folding. Not hard to find information, amazing stuff. In any case, Leela (amongst others) used the DCNN architecture (Google published numerous articles on techniques, they are wonderful), and the recent work on KANs is another example of how the area is developing.

Have fun reading up.

  offramp: User: Muttley101 your précis is perfect. I'm going to have a look.

When I lost to Mephisto I must have thought, "This game will create protein folding."
