    Thank you for the birthday wishes.

    Cloud computing is ok for things you do not care to keep secret. As mentioned above, companies see the value of a deeply evaluated chess position. Intel is running a freebee on cloud computing. But in the fine print... can they copy the results?
    Francis ,you have computers working on music, would you trust running that in a cloud computer?

    My machines are working 25 hours per day.

    Sam is the ICCF database freely available? Because you and Pino Verde plus all those who represent Canada in the Correspondence Chess world use engines (as everybody is allowed to do now) for your moves then your moves are gold.

      P.S. Thanks Frances........
      Bob!! 64 is significant for those who play that easy game. I am a Go player remember? 361 is my number!

        Your computer evaluations must go to 60 ply at least. Terms of agreement are flexible.
        Of course if you need evaluations and do not have a computer I can provide them (for a fee ).

        I'm wondering if anyone has done this already: set up the standard chess opening position, then switch Black's King and Queen. Now each side's King is on the same file as the other side's Queen.

        Analyze this using some of these computers you are talking about Mario.

        What I am wondering is if the resulting opening tree would be as extensive as it is for standard chess, or would this setup somehow give too much advantage to one side or the other.

        I started doing this with my 8-core computer and Stockfish 13. I was getting up to 36 plies deep, and the score was something like +0.5 for White, and so I played out that main line and then started the analysis again. Suddenly the score went to -3 point something! I haven't yet narrowed down just where the engine suddenly saw a drastic turn in favor of Black.

          You can get the ICCF DB games here: https://www.iccf.com/message?message=454

          You will probably want to filter out a few things to get quality games (even if everyone was using the "latest and greatest" engine version):
          - dates ... with the advance in engines, especially when NNUE came in, anything more than a few years old is produced by weaker engines (or people! egads... what a concept!!)
          - ratings ... unless someone is just starting out, if they are low or moderately rated, there is probably a reason (eg. old software, not letting engine go deep enough, etc...)

            Do you mean keeping an engine for a long time?

            Does a human interference help in this process these days?

              Deep = ply; how long it takes it reach any given ply depends on the CPU and the position.
              Human involvement doesn't help the evaluation, but with several moves at the same eval, having the engine run against these sub-variations (multiple iterations) sometimes helps in trying to figure out which move to make.

                New preliminary findings for the game:
                1) The black pieces have an advantage.... in the one thousandth of a pawn.(these result in a draw )

                2) There are thousands of unavoidable draws .If you can memorize the sequence you can draw every game.
                Computer-Computer tournaments where they are allowed to use opening BOOKS are finding this out already.

                  You might be interested in a recent Perpetual Chess interview with Matthew Sadler. He discusses the current state of this idea, not in the context of correspondence chess, but in the context of world championship preparation.

                  He also has some interesting things to say about Leela playing without doing any search (i.e. playing purely on an evaluation of the position after 1 ply). Apparently Leela is quite strong (better than me anyway) with only a 1 ply search.

                    Not entirely correct . Leela or any neural network is worthless unless trained. When leela plays a chess game it is misleading to say is at 1 ply search. The file containing the chess results is ready when 1 billion games or so have been played by it against itself.
