    12th World Chess Championships
    Capablanca vs Alekhine 1927
    Buenos Aires

    Why did I choose this match?

    There are several reasons why I wanted to analyse this famous World Championships.

    Capablanca is often quoted as one of the most accurate players of all time. He is statistically one of the least blunder-prone, so therefore I would expect quite a high top 3 matchup figure. In 1927 he was almost confirmed World Champion before the games started, such was the expectation of a straightforward win.
    World champion from 1921 to 1927, many people regard Jose Raul Capablanca as the very best player who ever lived.

    He faced in Alekhine, one of the most natural combinative players in the history of the game. A lethal tactician who was coming into his prime, Alekhine prepared rigorously for this match, both mentally and physically. He was also one of very few players around at the time who could stump-up the match fee of $10,000.
    Alekhine is consistently in top 10 lists of all-time best Grandmasters. In the 1920’s and 30’s he dominated the chess scene and was easily the world’s best player, holding the World Champion title for a total of 17 years until his death in 1946.

    There were plenty of longer games to analyse in this almost rather bloated affair. Virtually all were variations of the QGD, so I considered that the two protagonists would not only be familiar with the openings (and the middlegame positions that follow) but that the standard of play by both would be incredibly high from the start.

    Although over 80 years old, I consider the 1927 World Championships to be well worthy of the exhaustive(!) engine matchup analysis that follows.

    All conditions were the same for all games analysed and for obvious reasons, a game is classed as ‘out of book’ if I cannot find the position prior to this 1927 match in the chesslive.de database.

    Game 2

    This goes out of book on 9…Nxd5, so with 10 non-book moves analysis is of little use.

    Fascinating piece of work. I was wondering if you learned much from looking over these games
    and what conclusions can be drawn from the analysis.

    Could some of the low match up rate be attributed to the analysis engine being designed to work
    with chess theory that didn't exist at the time the matches were played?

    very interesting, especially considering Capablanca had the better match-up figures, but lost the match.

    nit-pick: if Alekhine reigned from 1927 until 1946, that would be 19 yers, rather than 17 as stated?

    Alekhine lost the world crown in 1935 to Max Euwe only to regain it two years later in 1937. That's the missing 2 years.

    ah yes, i forgot! thanks...

    Since this seems to be a hobby of yours maybe you would welcome suggestions of players to check in the future?
    In my opinion Bent Larsen would be interesting to check.Also Petrosian and Smyslov.
    And how about the young GM's of today: Carlsen,Caruana,Wang Yue,Stellwagen etc...

    If I do another Super GM match it'll probably be Kasparov-Karpov WC 1985.
    Next up I think will be analysis of a pre-computer era correspondence chess World Championships either from the late '60s or early 1970s.

    One thing I noticed throughout Capablanca-Alekhine '27 is that although Capa had slightly better total average matchup stats, he was actually more inclined to make a howler than Alekhine even though Capa consistently played top 3 moves.

    Alekhine had plans that were often outside the engine's top 3 choices, although the scores were often only a few centipawns out. Many times Alekhine played consecutive moves not in the top 3 which were still solid moves and often gave Capa very few logical replies as far as Fritz was concerned.

    Even taking this into account, the results for both players are below the upper end of human ability thresholds of
    top 1 match = 60%
    top 2 match = 75%
    top 3 match = 85%
    which was not so surprising.

    What a work! amazing.

    I have one question: the human upper limit you suggest: is it for an average on a sufficient amount of games? or does it apply to all games?

    It's 20+ games all with 20+ non-database moves.
    That is, a sample of 400+ non-database moves.

    Matchup rates for individual games can of course be much higher than those stats. It's the average total matchup rate that's important.

    Very interesting stuff.

    My first thought was that using this method you could work out who truly was the best player of all time(in the computers eyes anyway). But as you point out, in this match the loser had the higher match up. Seems that style plays a big factor. I’d guess that an analysis of a Kasparov/Karpov match would give a similar result.
