Kasparov Wins Game 3 Against X3D Fritz

Vulcao writes "Garry Kasparov just brilliantly won game 3 in the Kasparov vs. X3D Fritz chess match, which pits man against machine. Kasparov created a positional advantage on the queen side with a very strong pawn structure to which Fritz didn't have an answer. The result is now 1.5 - 1.5, and the last game will be this Tuesday, Nov. 18."

    Computer chess games deal with statistics and historics of previous games to decide how they will move their next turn. Usually they analyze hundreds of thousand of differents moves, even dumb ones !

      I play a lot of chess and I can tell you I've never once in my life 'pruned a search tree.' Humans just don't play that way. When a human rejects the vast majority of possible moves he's not even considering them. Pruning a search tree--what a computer is doing--entails actually exploring each move on the tree as far as it can. Then it assigns it a numerical value and orders the moves. Humans, on the other hand, have the ability to instantly spot whether a move is worth exploring or not. Whereas I would be able to eliminate a move like moving my knight back to its original square within the first three moves, a computer would actually have to examine the tree that a move like that would generate (barring an opening book which in my opinion is not an example of chess playing at all.) At any rate, programmers love to think that since a computer does something one way, and computers are 'electronic brains' then the human mind must work the same way.

      When humans play they rely primarily on pattern matching rather than searching a tree (unless they suck). Computers tend to be very poor at pattern matching, and humans tend to be extremely good-that's why a small child can look at photographs and categorize them instantly, but the most advanced computers have great difficulty with that kind of task.

      Most skilled human chess players apply pattern matching by looking at the board and identifying interesting things. They start with nothing and add new options to the list until they feel they have a sufficiently comprehensive understanding of the situation.

      Search tree pruning, by contrast, starts by including the entire space of potential moves and identifying courses of action that can be eliminated. Alpha-beta pruning is a particularly poor example here since it has the useful property that all a-b pruned subtrees are guaranteed not to be optimal. However, humans often ignore superior courses of action and choose suboptimal ones that "feel right" or match prior experience.

      There have been various experiments on the limits of raw pattern matching ability with chess pieces. An interesting one involved asking participants to memorize an arrangement of pieces and reconstruct it a minute after the arrangement is removed. Participants included people with little or no chess experience and masters.

      Those without experience memorized it as raw data, and did as well as they would have if asked to memorize random numbers instead of chess arrangements. The masters were more interesting. They did about the same as the beginners on random arrangements that could never actually happen in a game, but they were infinitely better at reconstructing realistic arrangements that often show up in games. The experiments proved that masters can recognize groups of pieces and evaluate them collectively.

      In a game situation this means the master looks at the board, and certain parts of it just stand out. The master will pay no attention to areas that don't grab his attention, and doesn't need to evaluate whether any of those individual pieces are worth moving. Interestingly, this means that playing with nonstandard rules (such as changing piece movements) will likely devastate a master's ability while only slightly reducing an amateur's skill level and leaving the computer's ability unchanged.

Which is, that the Kasparov is playing a computer program that is not thinking entirely for itself. A lot of the decisions that the program makes have been pre-programmed by the team of chess experts prior to each match. It's the group of experts that evaluates the opponent and decides the general strategy of each game.

      The program isn't altered in the middle of a game. But it also isn't Kasparov versus a completed chess program thinking for itself.

Some while later, a "competitor" was demoing a Windows version of a type of program for which I had put a great deal of effort into a DOS version. The program had a lot of graphical and interactive displays of scientific plots and other data, and I knew enough about Windows and all the stuff you had to do (WM_SIZE, WM_PAINT) to make it look right, and I suspected my acquaintence was "first to market" by taking a lot of short cuts on his UI. He let all the scientists in the room play with his program, but he was very reluctant to let me near the thing -- because the first thing I was going to do was try and break it to find out how much work he had yet to do.

    The only way Kasparov is going to beat that chess program is if he uncovers some limitation or shortcoming -- in other words to break it, and once broken I bet he could beat the thing at will. Last time around the cheat was a team of programmers hanging around trying to patch the program as soon as Kasparov latched on to such a weakness.

    The chess program will have reached true AI (in a limited problem set) once Kasparov is able to find a weakness, beat if for several games straight and for the program to somehow learn from what is going on and "close the hole", and if the program can withstand other such attacks from other chess grand masters and likewise "close the hole" without going unstable (one of the problems with learning algorithms is that can overadapt and go into limit cycles).

Meanwhile, any of them could "Hello, World" Kasparov into a quivering mass of jelly, if the battle were waged on their own field of expertise.

      So what is actually going on? The programmers have been given a problem (chess) to solve, and have created a system that is very good at solving it. Kasparov is also good at "solving" chess, and he's putting his expertise in that field up against the best automated chess-solving system that can be devised. Meanwhile the programmers are improving the rules governing the automated system as the game progresses.

      AI requires some level of situational awareness, but what you describe is a form of self-awareness. Admittedly, a program able to analyze its own rulesets and tactics for weaknesses is higher on the AI scale than a program which slavishly follows them.

Chances are, the program currently has some limited "self-adaptation" built in; it's just not robust enough to allow the programmers to exit the loop entirely.

      The comment about "breaking things" is very insightful.

      I'm no master chess player, but I used to play a lot of chess against Sargon III on my C=64 back in the day.

      I discovered, quite by accident, that the chess engine in Sargon III could not see "indirect" attacks (there's probably some real chess term for this - if you want to threaten a piece with some other piece, put some third piece in the line of intended attack, move the attacking piece into position, and then "reveal" the attack by moving the "blocking" piece someplace else)

      After a while, the program had trained me to set up these elabourate attacks... that a real human, even another amatuer like myself, would instantly recognise.

      Say... I wonder if the computer was programming me?

    Its ridiculous to say oooh the computer has beaten the human. Whats actually happening is that a human unassisted is being beaten by a team of humans using a tool (the computer). Computers are just tools. What this means is that us dumb humans have figured out a way to model what this really smart (well good at chess at least) human is doing. To me its about as big a deal as saying ooh the worlds strongest man just got beaten by a guy with a forklift truck.

  29. Mod up! by EvanED · · Score: 3, Insightful

    The parent hit the nail on the head. Computers require a different strategy than human players. For instance, there was one particular move in this game that illustrates this, 18. Rb2, that is a loss of tempo against a human opponent. However, against Fritz it was a very smart move. The computer should have moved the piece on f6 then pushed its f pawn to f5 then f4, attacking Kasparov's f pawn. Moving Rb2 however had the effect of making black work a little harder to attack, apparently pushing the number of moves it needed to consider to find the advantage beyond where it was searching. Against a human player it would have had little or no effect (all the commentators were saying how Fritz was ignoring the opportunity with the f pawn), but against Fritz it made Kasparov's game much much easier.

  30. An interesting game... by TygerFish · · Score: 4, Insightful

    The game was interesting. It resembled a classic game from the thirties with either Saemisch or Maroczy as white. It underlines the strengths of the human mind versus computers.

    The annotators of the first game pointed out over and over again, that some of each player's decisions were based on the computer's looking over a few million positions, and 'knowing' that it was safe to play the kind of moves that a human's fears and instincts would have made it very uncomfortable for a human to have played (e.g., the capture of the bishop by the king in the drawn game). Games like the first two show the greatest strengths of computers: superhuman ability in positions involving the calculation of tactical complications.

    The current game by contrast grave rise to a position that is possibly the greatest illustration of a human's real strengths: the ability to create closed positions where tactical calculations of severely reduced utility; creating a position where experience and 'instinct' far outweigh calculation.

    In the latest game, the computer's playing, 5...a6 created a 'hole,' a 'positional weakness,' and the rest of the game was a matter of exploiting its consequences while simultaneously giving the computer no chance to balance the game neither by winning back material, nor by a compensatory attack against white's position.

    To put it another way, the nature of the position allowed white to create and exploit a position where the computer's ability to look at millions of positions per second was essentially useless.

    It was clever and precise play on Kasparov's part.

    Connect Four by James Allen in September 1998. (First Player Win)

    Let's see John W. Romein and Henri E. Bal from that wonderful games research group in U of Alberta solved Awari in 2002. (Draw)

    Read Victor Allis' PhD thesis for a good overview on finding game theoretic results of games. He invented the proof-number search technique that he used to (re)solve Qubic and Connect-Four. http://www.cs.vu.nl/~victor/thesis.html


    Nine Men's Morris is not researched actively anymore, but Ralph Gasser's paper is often cited in any paper that deals with artificial intelligence in games.

    Of course, even though the game might already be solved, that does not mean that it is not fun to play...

    Something as intense as calculations for chess really much push the brain to its "limits."

    Sure, but:

    The X3D technology fools the brain into seeing 3D. I wonder how much this 50% lack of visual stimuli changes the way the chessmaster's brain works here.

    No effect whatsoever, because there is no "50% lack of visual stimuli". Anything that flickers fast enough is perceived by the retina itself as a solid unchanging image.

    The "critical flicker fusion rate" that determines "what is fast enough" varies from about 40 frames per second to about 80 frames per second, depending on image brightness, ambient illumination, the particular individual viewing it, etc.

    TV in the US, for instance, flickers at about 60 hertz, but in non-flourescent ambient illumination, most people don't notice. In Europe the rate is 50 hertz, and people frequently do notice. And some people get headaches from computer monitors that flicker even at 72 hertz, especially under flourescent lights.

    I used to regularly get annoyed at PC monitors in conference rooms flickering at 60 hertz, when others didn't notice -- so I'd bring up display preferences and set it at the highest refresh rate. Until it occured to me that I was sabotaging people who needed to interface it to the overhead projector at 60 hertz. Oops! :-) But I digress.

    Movies are displayed at 48 hertz (although only 24 unique frames per second; they are "double-shuttered" to double the frame rate). Cartoons sometimes have as few as 6 unique frames per second (although they are displayed at movie or tv flicker rates) because that's about the threshold for perceiving continuous motion. Lots of issues, lots of thresholds.

    But even if the 3D viewing shows perceptible flicker, there isn't any issue of "50% lack of visual stimuli". Both eyes are constantly receiving information.

    I could imagine that any number of things about this 3D gadget could distract a chess player -- but so does cigar smoke (a trick used to advantage in chess matches early in the 20th century).

    Years ago I used to use similar 3D goggles to play first person shooters like Quake, and it was great. It helped my game. Quake isn't chess, but 3D goggles aren't rocket science.

    You can assume that, if he agreed to use this 3D setup, he was confident it wouldn't throw off his game. He does care, after all.

    The position after 29. a6 was indicative of how paranoid Kasparov was about the computer's tactical capabilities. In addition to the pawn blockade stretching diagonally from f2 to b6, he had marched his king all the way from e1 to b2 and protected it behind a wall of pieces. The king's bunker looked like this:
