Comments.Text: I am still a bit confused by the actual numbers. If I add all three percentages in a row I end up with a number below 100%. Shouldn't it be above 100%, since you also have moves which are captures and checks at the same time?

Comments.Text: You really need a 'total number of moves' column. Also the settings for the computer games matter a lot, especially whether tablebase positions are considered to finish the game or are played out to the end.

  I'd be careful drawing conclusions from this data only. Most captures (in %) happen in the opening/mid game, so shorter games will result in a higher percentage in the "captures" column. I would expect this to be the main reason for the data you see in that column (and not Carlsen avoiding capturing pieces). Perhaps you could analyze the average number of moves of the players!?
  
  There can be various reasons for shorter/longer games:
  
  * Humans resigning/drawing earlier than computers
  * If a player is playing at a much higher level than his opponents (which is not so much the case nowadays anymore, but perhaps was at the time of Kasparov and before), this could result in those players winning games out of the opening.
  * Different style; a more tactical player might have overall shorter games than somebody like Carlsen who likes to slowly build up an advantage
  * Particularly in recent years top players, when facing much weaker opponents, try to avoid exchanging pieces. This is done to keep the position complicated and not necessarily represents best play.
