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."

    ...with people saying that if the computer wins over the human it means that "That's it, here we are, computers are more intelligent than man".

    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 !

    When a human player take a look at the chess board, he rejects the vast majority of the possible moves and concentrate only on very few of them.

    I would call that efficiency and if computers where as efficient as human, they would win easily without requiring huge processing power.

      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. Newsflash: brains are not digital computers.

      Its not so much a matter of computers doing things one way and humans doing things another way, but a matter of both being bound to the rules of computational theory. There is a large solution space, and both humans and computers have to decide what parts of the solution space to search and what parts to ignore. They have to do this, even if they do not do this in the same way. That's all that pruning the search space really means.

      Now, just because you don't do it conciously doesn't mean you don't do it. Your brain does an incredible amount of processing behind your back. Think about visual processing or auditory processing. All of that goes on completely outside of your concious thought.

      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.

      Even though I think the parent is a troll, here's an academic article detailing some other experiments on the topic.

Computers think about the game in a very different manner, and I think eight pawn chess highlights where their weakness lies. They do not have a plan. They do not start the game with a long term plan to the ending. I believe that in the past, Garry was a true sportsman and did not play eight pawn chess against the strongest computers.

    As Fritz moved its pieces back and forth throughout the game, Kasparov could make several free moves. That isn't brilliant, that's just making use of the other guys mistakes. Kasparov dominated the whole game, while Fritz had no clue at all what to do. According to one of its makers, X3D Fritz reached a new record of reading deeply (19 ply if I'm not mistaken) since the number of possible moves was so small in the cramped space they were building up their positions. This, however, didn't help a bit and I had a few giggles over bishops and knights moving away and then back again to the very same place they were coming from.

    Only at the very end did Fritz realize it was losing, throughout the whole game it couldn't see what was glaringly obvious to the audience.

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.

    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.
