Fritz 13 Let’s Check Example – Very impressive!!

Here is an example of the power of the “Let’s Check” functionality in Fritz 13, which is really impressive.

I submitted a game I played on Wednesday night against Paul Covington using the “submit game” feature.

This takes the game, and

  • breaks in into unique positions after each move
  • distributes each position to people who have volunteered to let their computer work on evaluating positions that others have submitted
  • then saves their results, that anyone can then access

Nice!

Below is a snippet of the output.

For example with

6…cxd4 [0.02/0]

 [6…d5 7.0–0 Qb6 Deep Rybka 4.1 x64/derkranvonhuenge -0.06/18]

6…cxd4 is the 6th move that Paul played.  This was evaluated as being a 0.02 (2 hundredths of a pawn better for white).

Below that is the recommended move, which was to play 6…d5, which would give a .06 of a pawns advantage to black (the negative means it is to black’s advantage).

The computer used was Deep Rybka 4.1 and the username is derkranvonhuenge (Gesundheit!).

The 18 means that it went to 18 ply. (each individual move is 1 ply)

So basically, I submitted a position, and then an army of computers all around the world went to work figuring out an evaluation of every single position in the game.

After it was done, I could use the “Let’s Check Analysis” button, which retrieved all of the information that others has posted, and put it automatically into the game.

All together this took about 3 mouse clicks!

Wow!  This is AMAZING!!

Below it is a sample from the first 10 moves.

  1. Hi there! I’m the guy that did your move # 10. for white (Zirie). You are welcome.

    I am currently ranked #3 in the Honors List, and I am aiming for #2 or #1 some day.

    I wonder if you have any idea of which engine is most productive in earning points on a i7 processor.

    • Hi Roberto!

      Thanks so much for the comment! That’s really cool that you are so high on the Honors list!

      I am not really sure which engine is most productive in earning points. I have noticed that I often get a higher ranking with a lower depth with Rybka 4.1 than I did with Fritz 13. Not sure what that means.

      I have noticed also that it is getting harder to gain points, because there are more and more people checking variations, so I will end up losing points as people “win” a variation that I previously earned points on :-)

      If you would be interested in doing an article about “Let’s Check” and how you were able to get so high on the list, I would love to publish it!

      Good luck trying to catch Mely – he has a ton of points! I am guessing he is running multiple computers to get that many points.

      Thanks again for the comment!

      Cheers,
      Tim

  2. I would be willing to write the article, of course. But let me first get to #2. PacificRabbit is putting up a fight! (with 80 points a day on average).

    For a while now my eyes have been, not in Mely, but in Deep Mira, who I have been tracking for over a month since she was back in position 80 or so, and who is raising at an incredible speed. She is gaining about 140 points a day on average (vs my 85 a day on average).

    I agree with both your points, that Deep Rybka gets you ownership at lower depths than, say Houdini. But I also notice it takes longer for my PC to reach those depths, so I think CB is compensating for the presumed ‘retouching’ of Rybka’s true depth.

    I agree with the ‘one line does it’ assessment. I have a couple more recommendations, which I will gladly reveal once I’m in the highest position I can reach, hehe!

    Cheers,

    Zirie

  3. OK cool – that would be really interesting! I get a lot of hits on my website for people looking for information about “Fritz 13″ and “Let’s Check” so I don’t think that there is a lot of information out there for people who are interested.

    I don’t think that Mely is using a very powerful computer or engine. If I get a position that he has done analysis on, I can normally get a higher ranking. I think that he has just been at it for a long time, and probably has more than one computer running at a time.

    Here are a few of my tips:

    Let your computer run as much as possible (obviously)

    I just do “contribute engine” engine going for as many points as possible, instead of hand picking lines, and going for the “depth” bonus, or trying to win popular variations which give the more points.

    Installing endgame tablebases seems to have helped solve a problem where Fritz 13 would get stuck on positions that had a clear cut analysis – like a mate in 5 or a dead draw.

    Installing the latest Fritz patches will help keep it from freezing up as well.

    If you don’t have a powerful computer, make sure as little is running in the background as possible (programs in the tray, etc).

    I use the “full analysis” and “blunder check” quite a lot to look for tactics for my newsletters. I wish there were a way I could get Let’s Check points for these :-)

    • I think both Mely and Deep Mira are using very powerful machines. Mely told me, after I inquired, that he’s using a 24 core computer. I guess Deep Mira should be around that, too. Very powerful machines, indeed, possibly two Xeon processors, with 12 cores each, working in parallel.
