That's impossible - each chess game adds 1 point to the score (two .5's or one 1.0) so you need an integer sum. You can't get the score of 8.5 given here no matter how hard you try. Either one of those numbers is a typo or (more likely - I don't see how you'd get .5 instead of .0) this tournament is fake. |

| Jun-30-10 | | turbo231: Looks as though Rybka4 is winning. What hurts Houdini is no end game table bases. WHY did they turn ponder off? When I conduct matches I never turn ponder off. In fact I never turn ponder off. Why would you want to? This match could be controlled by the people at Rybka. Is this a legitimate match? Money can buy and Rybka has the money. They could've turn ponder off because they didn't want the engines using the processor at the same time. That would make sense if they're using the same computer. I think I'll start turning ponder off because some engines hog all of the cpu. And some engines don't have the ability to stop them from hogging all of the cpu. So it's ponder off from now on. |

| Jun-30-10 | | The Rocket: I dont get how free-engines like stockfish and houdini have gotten so strong that they can beat rybka? they used to be quite weak the last couple of years(the free engines).. is there something revolutionary that has happened to the chess engine world? |
|
| Jun-30-10 | | SugarDom: It's just the algorithms...
Rybka programming apparently is not that elegant... |

It could have been a simple mistake. No one except zanshin knows. I was talking about ponder in the previous kibitz and that from now on I will turn ponder off. That depends on the match or game, standard time limits ponder off, bullet or lighting game ponder on. A long blitz game ponder off, a short blitz game ponder on. |
|
| Jun-30-10 | | SugarDom: Turning ponder off will be a blunder...
Pondering gives a more accurate picture of the chess engine's strength. |

 | | tarek1: It's amazing. I first heard about these new engines in this very forum, and installed them using the Shredder interface :
Stockfish, Fire, and Houdini. I had Rybka 3 and 4 before. On my computer, Fire is the strongest engine in blitz (3') matches.
I wondered if it was specific to blitz, ands I set up a match between Fire and Rybka 4 with 20' minutes games, with 20 games, to find out. Fire crushed Rybka +9=10-1. |
|
| Jun-30-10 | | The Rocket: <"It's just the algorithms...> <Rybka programming apparently is not that elegant..."> doesnt make sence to me.. if free engines are able to be stronger or equal to rybka. But the established programs like fritz, shredder and junior with a hole team working on them are still way behind... |

 | | Eric Schiller: Depends on what you mean by "eloquent
" TobyTal's claim to fame is that it is superstrong with a very small amount of code. |
|
| Jul-01-10 | | zanshin: <What is multiple PV? I am really liking houdini. Really a magician!> Multiple PV is when the engine analyzes more than one line (principal variation) at a time. |

That's impossible - >
These are partial results. The completed tournament was posted in my forum. 1. Houdini_w32_4CPU: 12.5
2. Rybka 4_w32: 10.0
3. Fire_131_w32_KLO: 7.5
Round robin three-engine tournament, 10 rounds - totals 30 points. Right? |

| Jul-01-10 | | zanshin: <turbo231: Robin Smith wrote a book about chess engines idiosyncrasies and chessbase did review of his book in 2004.> <turbo> I also reviewed this book in the chessbookforum. Unfortunately, I might have overdone it as I wrote a 5 part review starting here: ChessBookForum chessforum Also, you can check my forum header for all the types of positions engines in general don't solve. Most of them are from Smith's book, some are taken from other sources and specific to Rybka. |

| Jul-01-10 | | turbo231: <zanshin: I also reviewed this book> Thank you for that info. You've done a lot of research on this subject. Very interesting. I'm going to have fun with this. Thanks again. |
|
| Jul-01-10 | | zanshin: <turbo> I find it a fascinating subject. If there's anything I might be able to help you with, feel free to ask. |
|
| Jul-02-10 | | SugarDom: For single CPU, there's a claim that Robbolito is the strongest. I believe this. |
|
| Jul-02-10 | | Nina Myers: Some have a disposition to believe things without waiting for concrete proof. That's what I call dull! |
|
| Jul-02-10 | | r00ki: Which is stronger on a dual core machine? Firebird or Houdini |
|
| Jul-02-10 | | zanshin: <r00ki: Which is stronger on a dual core machine? Firebird or Houdini> For single line analysis, I would guess Houdini, but it might depend on the time controls. |

| Jul-16-10 | | Sydro: Houdini 1.03 has been released. New features:
Multi-PV, searchmove and large page support. Improved evaluation function. http://www.cruxis.com/chess/houdini... |
|
| Jul-16-10 | | zanshin: <Sydro: Houdini 1.03 has been released.> Thanks for the tip. I will try it out. |
|
| Jul-17-10 | | turbo231: me too. Great news for me I now have a 2 core laptop. They had to upgrade the motherboard. It's only a T2450 processor(old laptop that was the max it would take) but I love love love it. I'm multitasking now! Time to check the Rybka vs Stockfish match. Rybka defeated Houdini in the first match 26.5-21.5. That was the Houdini 1.02 engine. |
|
| Jul-17-10 | | turbo231: After 31 of 48 games Rybka4 is beating Stockfish 1.8: 17.5-13.5. |
