A Data-Driven Exploration of the Evolution of Chess 109

Posted by samzenpus from the what-does-the-horse-do-again? dept.
HughPickens.com writes Randy Olsen has a interesting article where he explores a data set of over 650,000 chess tournament games ranging back to the 15th century and looks at how chess has changed over time. His findings include:

Chess games are getting longer. Chess games have been getting steadily longer since 1970, increasing from 75 ply (37 moves) per game in 1970 to a whopping 85 ply (42 moves) per game in 2014. "This trend could possibly be telling us that defensive play is becoming more common in chess nowaday," writes Olsen. "Even the world's current best chess player, Magnus Carlsen, was forced to adopt a more defensive play style (instead of his traditional aggressive style) to compete with the world's elite."

The first-move advantage has always existed. White consistently wins 56% and Black only 44% of the games every year between 1850 and 2014 and the first-move advantage becomes more pronounced the more skilled the chess players are. "Despite 150+ years of revolutions and refinement of chess, the first-move advantage has effectively remained untouched. The only way around it is to make sure that competitors play an even number of games as White and Black."

Draws are much more common nowadays. Only 1 in 10 games ended in a draw in 1850, whereas 1 in 3 games ended in a draw in 2013. "Since the early 20th century, chess experts have feared that the over-analysis of chess will lead "draw death," where experts will become so skilled at chess that it will be impossible to decisively win a game any more." Interestingly chess prodigy and world champion Jose Raul Capablanca said in the 1920's that he believed chess would be exhausted in the near future and that games between masters would always end in draws. Capablanca proposed a more complex variant of chess to help prevent "draw death," but it never really seemed to catch on.

      Long ago I gave up this game for this very reason. In most games at certain skill level it becomes more about who makes a mistake vs who adopts or invents a better strategy, as all optimal strategies become known. At this level games cease to be fun for me. When a game is so over analyzed that it becomes clear "You must do X or you will lose" it is just not fun. You become forced to play a certain way.

  • A strange game. The only winning move is not to play. How about a nice game of chess?

  • Unless mechanics prevent them by some hard method any sufficiently analyzable game will inevitably result in nothing but draws between two sufficiently skilled players. There will be variation on an individual level of course, nobody plays at the top of their game all the time, but as a whole the larger trend will be towards universal stalemates. Only games where mechanics do not permit stalemates by optimal play will avoid this.

      I used to help direct tournaments, including the US Chess Championship. The number of draws is pretty amazing, and part of it is the level of competition. They get material reduced to a certain point and position, realize that neither player is likely to make a catastrophic mistake, and offer a draw. I watched Josh Waitzkin and Boris Gulko battle it out to a closed position where they had lots of movement available, but neither could get a decisive advantage without a blunder, and that just wasn't going to happen. They drew, then went back to the break room to replay the game and see if there was a way around it.

      And then there's a certain player who would offer a quick draw then go to the nearest casino to play poker, which he was quite good at and normally won more than the tournament would have produced. And still get his appearance fee for the tournament.

  • More defensive and more draws. Sounds like chess is getting boring.
  • Draws are much more common nowadays, because in 1850 there was no ELO system and competitors were more likely at different levels. Nowadays, in official competitions a lot of games have people with similar ELO playing together, increasing drastically the odds of a draw.

  • Less than 56% for White, really (Score:5, Insightful)

    I actually had to read the article to figure this out. The statement that White wins 56% and Black 44% is for games in which a non-draw decision is reached (per the actual article). But with 10% to 33% draws, the actual difference in score is definitely lower. Conventional scoring is 1 for a win and 0.5 each for a draw.

    So White does have a persistent advantage, but the spread is lower than 8% going by score. And I think you have to go by score, that's what counts in tournament play.

    Let's say over the time period in question there are 20% draws (just for the sake of calculation). Out of 1000 games there are 200 draws. White wins 56% of 800 or 448, so Black wins 352. White scores 548, Black 452, or 54.8% to 45.2%. Still a clear White advantage, but somewhat less, and lesser still as we approach the modern 33% drawn.

    I had a chess computer, maybe a Kasparov 1985 16K. It had a 'behavioral' error. It would allow it's side to "castle" when the king was in check, a violation of the rules. It would enforce the rule and not allow "your" side to do that.
    As evidence that the programming in chess computer games has been recycled, I have seen that same error happening in a few other chess games on computers, including a mid-2000 'oughts' computer chess by Ubisoft. Check Wikipedia Chessmaster, which only mentions games after 1988.

      If you have ever written a chess playing program, or only a chess move validator, you would have seen how hard this very issue is. It is only slightly easier than checkmate & stalemate detection. The reason being, that you have to analyze the opponents' moves. So before you know, even when only validating, you are already recursing.

    First, for someone who has been playing chess competitively for the last twenty years, none of the results of the analysis is a revelation. Like so many "data" posts that seem to be in vogue, this one states quite the obvious viz the game of chess has evolved and has improved in quality. Hence opening colour matters, games are longer and many end in draws. DUH! As a secondary point, the OP makes a big show of the "steady increase" increase in length of game from the 1970s. On closer inspection, what is implied is that the average game has gone from 37 moves to 42 moves. For a chess player, that increase is hardly significant and can be attributed more as a result of prevailing opening theory and chess playing style than reflective of anything else. A clear case of data-blindness.

      This just turns a draw game into an endless game. Since captured pieces are redeployed, there will be no "true" late game if both players are skilled enough and make no big mistakes.

      • It just takes a slight shift of power, or one small mistake, for one player to get momentum and end up with the majority of pieces.

        • Letting the opponent captures a piece without any tradeoff is a huge mistake, not small mistake. So I would say for top-notch players, it's rare for one side to have majority of pieces that easily.

          The unit promotion mechanism also makes no pieces really "weak". Unlike internatioal chess, pawns don't need to reach the bottom to upgrade. Walking 2/3 of the board will do.

The wrinkle on playing is that you have to have the rule that if a piece CAN be captured during a players turn then the piece MUST be captured. If there is more than one option to capture the player being forced to capture has choice unless the King is one of the options. (can be played King capture optional too) If your King is captured, you win (b

    The set the author used suffers greatly from selection bias. Games are usually only included in commercial databases because they're interesting, or were played by interesting people. So I'm not sure anything interesting can be drawn from his results.

    Also, there needs to be some control put in place to account for rating differences. The Eli system isn't that old, and in the past players with drastically different levels of skill were more likely to play each other.
