For example in the first row and second column, Stockfish vs Houdini, the result is 27-25+7-3=-16. I understand that 27 signifies Stockfish's number of wins+ draws, similarly 25 signifies that of Houdini. But what does "7-3" signify? and how is the result -16?

And what does the blank in Row 1, column 7 mean? similarly in (6,11), (7,1), (7,10), (7, 12), (10,7), (11,6), (11, 12), (12,7), (12,11). Do they signify that those matchups have never happened? If so Where should I look for if I want comparison of such matchups?

This question may be weird, but please at least guide me where should I ask these questions if not the answer.

    A partial answer: The first row in each cell gives the match result in points (1 point for a win, 0.5 for a draw, 0 for a loss), the second row gives the games' results: 7 wins, 3 losses, 40 draws. You should ask the publisher of this table for further details. – muclux Feb 28 '18 at 17:58
  • Thanks, you're right. I'm very stupid to not see it. As for the publisher, I tried to make an account in ccrl forum, but the registration captcha is too tough, which I failed 12 times and counting. Any idea why the result of 7 wins 3 losses and 40 draws is -16? – Rajesh381 Feb 28 '18 at 19:51
  • They are rating performance. See my answer. – SmallChess Mar 1 '18 at 0:20

@muclux is right on the results. Check his comment. I'll answer what "16" mean.

Scroll further down on the page.

The number is the rating change. Stockfish lost 16 rating point to Houdini, similarly Houdini won 16 points from Stockfish (convince yourself by going to the Houdini vs Stockfish cell).

  • Thanks, just want to confirm, you are talking about elo rating, right? – Rajesh381 Mar 1 '18 at 4:32
  • @Rajesh381 I'm not sure how CCRl rating work. Send them an email? – SmallChess Mar 1 '18 at 4:33

I believe the answer to the meaning of the numbers is at the top of the list above that matrix.

column descriptions As for the blank spots, yes I believe those are for games which did not occur.

  • I don't follow, I thought that few lines above the table are the conditions under which the games were recorded – Rajesh381 Feb 28 '18 at 19:58
  • No, the first one is a list, the other is just the top twelve counted and put into a matrix. – TMcSquared Feb 28 '18 at 20:14
  • Yes, I understood that, but there's no explanation of how the result is calculated and filled in matrix. I mean what does the -16 in the photo I posted signify? – Rajesh381 Feb 28 '18 at 22:40
  • oh, sorry I misunderstood that part. – TMcSquared Feb 28 '18 at 23:46
