It was close, but Houdini was the best computer chess program in the end.

In a competition called Thoresen Computer Engines Competition, which ended Thursday, Houdini, a free program, finished just ahead of Rybka, which has won the last four computer world chess championships.

The competition was a double round-robin (meaning each computer played all the others twice, once with each color), and it used the Bilbao Scoring System in which each win counts as 3 points and each draw as 1. Houdini finished with 24 points and Rybka with 23.

Stockfish, another free program, finished third, with 20 points, while Ivanhoe and Critter, yet another free program, tied for fourth and fifth, with 17 points each, though Ivanhoe was fourth on a tie-breaker.

Rounding out the field were Shredder and Naum, which each scored 12 points, and Hiarcs, which ended with 11.

Early in the tournament, it looked as if Houdini would run away from the field as it won its four games. But it slowed down after that, drawing eight of its last nine games.

Meanwhile, Rybka, which started by losing two of its first four games, came roaring back by winning five of its last nine games. If not for a loss to Shredder in Round 13, Rybka might have overtaken Houdini and won the tournament.

It was an interesting competition because there were clearly differences in style between the computer engines — a reflection of how they were designed and programmed.

Over all, 24 of the 56 games ended decisively. Though the programs are obviously not perfect, they are better at playing chess than humans. That so many of the games were decisive would suggest that there is still a great deal that is not known about chess. (If more was known, presumably strategies could be programmed into the computers so that they would not lose.) It seems that we are still a long way from “solving” chess, as opposed to checkers, for example, which was solved several years ago.

Corus chess: So outplays third-ranked Frenchman


Filipino Grandmaster (GM) Wesley So made French GM Laurent Fressinet his second victim in the 73rd Tata Steel-Corus Group B Chess on Friday at the De Morianne Community Center in Wijk Aan Zee, The Netherlands.

So (2673 ELO), unfazed by his foe’s higher rating, played the disadvantageous black pieces almost flawlessly, needing only 42 moves of an English opening to finish off the third-seeded Fressinet (2707 ELO).

The 17-year-old Filipino chess wizard, who rarely settles for a draw, buckled down to work early and immediately challenged Fressinet’s bold opening play by accepting the gambit pawns while consolidating his kingside.

After a brief middle game battle that saw both players castle on opposite sides, So sustained his material and positional advantage. He gave up a pawn in his 20th move to force an exchange of queens that led to a rook-pawn endgame.

So was threatening to promote his h-pawn to a queen or capture Fressinet’s remaining rook when the Frenchman resigned.

It was So’s second straight win after a string of four draws. His first was a dominant victory over GM Surya Shekhar Ganguly of India in Friday’s fifth round.

So now occupies solo third place with four points behind leader GM Luke McShane of England (5.0 points) and second-running GM Zahar Efimenko of Ukraine (4.5 points) in the 13-round, category-17 tournament.

So’s seventh-round foe will be No. 2 seed GM David Navara (ELO 2708) of the Czech Republic. – JVP, KY, GMANews.TV

BOBBY FISCHER AGAINST THE WORLD Review

bobby-fischer-against-the-world-movie-image-slice-01

It would be nice if people we admired for their talent were also admirable for their demeanor.  Unfortunately, this is not always the case.  Bobby Fischer is celebrated as one of the greatest chess players who ever lived if not the greatest.  He was also “complicated”, “enigmatic”, and “private” which are all super-nice ways of saying he was a raging ass-hole.  And the arc of his life wasn’t one of redemption or even tragedy.  He was simply an ass-hole who was really good at chess who became a super-crazy ass-hole who was irrelevant in the world of chess.  Liz Garbus’ Bobby Fischer Against the World provides a solid overview of the chess prodigy’s life, but it doesn’t bring any new information to the table or offer any strong insights into the nature of greatness and madness.

Fischer mostly follows the chronology of its subject’s life with the centerpiece being Fischer’s famous match against Boris Spassky for the world championship in 1972.  It’s bizarre to think how much chess captured the national imagination and at its center was a kid from Brooklyn who essentially taught himself to play.  However, even from a young age, Fischer was astoundingly arrogant.  His parents didn’t play a strong role in his life and he devoted himself entirely to chess.  Garbus makes a weak argument that the nature of chess somehow rewired Fischer’s brain and drove him to madness.  I think the real culprit is that he was a young kid with no one protecting him and he was devoured by fame.  If you grow up believing you’re the greatest and you have the chess victories to prove it, then you’re likely to think that every thought that enters your crazy mind is the absolute truth.

However, Fischer’s chess skill is undeniable because everyone attests to it.  While Garbus does a good job of examining how the Fischer-Spassky games were played, she never explains what exactly set Fischer apart in terms of technical mastery.  Yes, he devoted his life to chess, but what was his style of play?  Did he play offensively or defensively?  Did he slow-play his opponents or go for speed?  Even presuming he could do it all, did he have preferences?  A visual representation of Fischer’s skill would have helped to provide a better understanding of his chess acumen even though his talent is generally accepted as fact.

But while Fischer may have been a grand master, he was a wretched sportsman.  Again, we want the people we admire to be heroes and usually they fall short.  But Fischer didn’t even bother to show up.  I don’t mind that he had a request for privacy if his real love was for chess.  But his behavior towards and during the world championship was despicable.  He showed no respect for the game, for his opponent, or for the organization hosting the tournament.  It was all about him and yet he was nothing without chess.  Greatness at chess requires brilliance, but Fischer was remarkably foolish in his behavior.

Going into the film, I already knew that Fischer was a chess prodigy and was an anti-Semitic jackwad who laughed at the U.S. on 9/11.  I went in hoping to gleam some insight into what made him a chess genius and one of the world’s most punchable human beings.  Bobby Fischer Against the World doesn’t really offer either.  It’s a well-constructed documentary that eloquently provides an overview of an infamous public figure.  But for those looking for a new angle on Fischer or a broader overview on his demented nature won’t find Bobby Fischer Against the World to be much of a game changer.
