Halfway

 I'm halfway my session of 150 days in a row tactical training according my newly developed method which took me 20 years to devise. From the 75 days in a row that I have under my belt now, I spent 52 days with solving and memorizing 500 tactical puzzles. I spent the last 23 days with educating my system I (the unconscious brain).

What is happening?

  • I forget the move sequences of the solutions of the 500 tactical problems
  • I start to see the solutions instead.
  • When I think about a problem I am surprised that the clock ticks much slower (about a factor 5)
  • I have way more overview in my head
  • I feel that system I is working miracles the past 23 days

Of course these are just feelings, which are subjective by definition. But have a bit patience, after another 75 days, mr. Elo will be the judge. I'm optimistic.

    1. That's the idea. Maybe I should say "Mr. Glicko will be the judge".

  2. Congratulations and best wishes for your continuing success!

    You should write a book about your training method. SERIOUSLY!

    (Not so seriously:) We can resurrect the Knights Errant of the Round (and Round We Go adult Improvement) Table.

    I (for one) would certainly volunteer for a controlled experiment (keeping records, etc.), although I think the results will not be as impressive for me. I've already been following at least a significant part of your method for some time - with tangible improvements. Like you, I can "feel" the improvement results, although I haven't been letting Mr. Glicko keep me honest about the quantity of improvement.

    Hope springs eternally!

      Nah, we need a more catchy name. What about "the spiralling vultures" or "the roadkill scavengers"?

  3. You should write a book about your training method. SERIOUSLY!

    We will see about that. I first need the blessing of Mr. Glicko. He can tell us something about the transfer ratio. How will the skill learned in one problem transfer to another problem? That is impossible to predict.

    OTOH, this is the first time that I feel system I working miracles since about 2007, when I had my greatest progress in rating. I always have been looking for that same experience, but no training method could replicate that feeling. Until lately.

  4. PART I:

    Here’s an interesting example which I think is a good demonstration of how PoPLoAFun enables one to logically find a viable solution in a tactically complcated position.

    FEN: r7/pbq3bk/1n1NRr1B/2pPNp2/6pP/8/2RQ1PP1/6K1 w - - 1 0

    Vorobyets – Kogan, Lvov, 1974 (I can't find the game score.)
    Test Your Chess IQ – Master Challenge, Test 8, #57 by August Livshitz

    The “leitmotif” for this position is given by Master Livshitz as “diversion.”

    It certainly is "diverting" - of a coherent approach to solving.

    There are no "obvious" checks, captures or threats to trigger pattern recognition.

    Aox's suggested question is very useful for framing the direction to search:

    What is the problem/position about (checkmate - material gain - Pawn promotion)?

    The actual game continuation follows the second-best solution (per computer). As an experiment, I tried playing against both programs from the starting position, following the recommended line(s). In both cases, both programs deviated from the (supposedly strongest) defensive lines after a couple of moves. That strikes me as somewhat bizarre. Even more bizarre was Komodo's response of playing (essentially) "give-away" to stretch out the distance to checkmate.

    FWIW: Here are the findings of two silicon monsters (Stockfish and Komodo on Chess Tempo). I set each program to consider 17 alternatives, simply because that covered all possibilities with a positive outcome for White. That is an EXTREME case of overkill!

  7. That's a freak problem! When almost every move wins, there must be a lot going on. That is the eternal problem with chess teachers. They want to show us the complex and the exceptional. But we must learn the simple and the common first.

  8. It's a simple example.. for thinking method.
    The black King is in serious danger so look for checkmate.
    If you can't find "anything" bring chess pieces closer, as stronger, as closer, as better.

    Everyone has the new stockfish-version?

    ReplyDelete
  9. I still use Stockfish version 9 on my laptop. I see that the latest version is Stockfish 12, with CCRL Rating: 3564 and CEGT Rating: 3512. My laptop is out of date (Windows 7), so I'll probably update Stockfish when I decide to update my laptop.

    I'm not sure which versions of Stockfish and Komodo are run on Chess Tempo. I expect that they use multiprocessor versions.

  10. As higher the rating as quicker the result of same qualitiy. Stockfish 12 should run on your windows 7 system too just muuuuch faster
