     Poemander says: "The only other thing you may need for meteoric rise is a mind like Jose Capablanca (observed three games at four years of age, and sat down to win three games against Dad)"

    The only evidence that Capablanca learned in that way, and won his first game against his father is his own account of it.  Do we believe it?  If he was not deliberately making it up it could easily be a false memory.  Several things cast doubt on its truth.  First that it is so unlikely that a four year old, on the basis of watching a few games, could beat even the weakest of adult players.  Second, that we do not, in general, have accurate memories from early childhood. Third, there is no end of examples of famous people in all walks of life exaggerating their achievements and experiences, or just making them up.  And finally, when you read Capablanca's account, it just does not ring true.

    Many a truth does not ring true on the basis of common experience. Worse still is spin from vested interests and centuries of its effects. Every lie is a roadblock in the mind. What are we subject to? What of other "cultures", like the Jews, for instance, and their history, actively suppressed by academics since1900 and long before already contradicted. They exist and much more so. What then, is their history, if you would gainsay? I believe, as did Newton & Einstein (my idea of scientists), that the diversity of humanity is a result of reincarnation. I have met or know of people with strange stories, like memories in their childhood years of dying in the Civil War. What do we know for sure? Research in that direction is not tolerated. It would explain the recorded game by Capablanca at four years and ten months old, but nothing much else will. Neither are Edgar Cayce or Patience Worth (read "The Case of Patience Worth" by Walter Franklin Prince) to be accounted for by "mainstream" thought, if properly reasearched. "Sauron does not share power!"

       From "The Unknown Capablanca" - David Hooper, Dale Brandreth

    Game 158 Ramon Iglesias - JRC

    Havana, 17 September 1893

    (Remove White's queen)

    This is Capablanca's earliest recorded game; he was four years and ten months old and too good, even then, to receive odds of the queen. From moves 12-23 he exploits the weaknesses of White's pawn structure - is it possible that he already had a grasp of position play?

       These two games of Ramon Iglesias are evidence of the great diversity of talents found throughout humanity (see MAT 25:14-46 KJV for the origin of the current interpreation of the word "talent"). In Chess, proportions of points won between any two players is possible, and ratings based on these measure playing strength. "On the chessboard lies and hypocrisy do not survive long. The creative combination lays bare the presumption of lies; the merciless fact, culmination in checkmate, contradicts the hypocrites." Emanuel Lasker.

       "Chess Translator, PGN Manager & Calculator", as it now identifies itself on the title page, is set to expire as a trial version. This encourages the user to update, as it evolves or debugs, from:

    http://www.swissimmaculate.com/

       The current version will soon be updated. Among improvements, the calculator is currently displaying the draw, which should be represented in highlighted colours as "1/2 (1/2-1/2)", as a win "1(1-0)" instead. Draws, however, are being processed properly. The program is large, complicated and error prone, and testing takes a while. Ignore this erroneous display if you use the calculator meanwhile.

    This text is created by "Chess Translator, PGN Manager & Calculator". The calculator was a last minute addition, and has been significantly refined with club ratings & tournaments in mind. To this end, work on the INPUT TEXT EDITOR is receiving attention, and will allow COPY or CUT & PASTE operations from a local text file ".\ClipBoard.txt" by default. This was used to label the games of the Capablanca-Corzo Match above. Capablanca  played the White pieces for odd numbered games (1-0 here means that Player A won, not necessarily WHITE). You may find it interesting to note the probabilities of Player A (Jose Capablanca) winning against Player B (Juan Corzo), as the match of 13 games continues. Are the calculated probabilities justifiable, do you think? Copy and paste this post into NotePad, and apply the suggested font for easier reading.

    To all interested in my universal CHESS APP, work on the INPUT TEXT EDITOR is full speed ahead. That has become essential with the capacity for cutting and pasting into or from the editor in bulk, using an arbitrary text file. I am hoping to complete this project before the current version expires after this year. The APP should become, to the aspiring CHESS CHAMPION, what a calculator is to an engineer. Meanwhile, I will share my PGN DATABASE details with you as a suggestion. The list below comprises 33800 games, somewhat refined using CT&PM facilities. As far as possible without intervention, CT&PM will identify and merge details of identical games, even with slightly variant player names. The suggested DATABASE should represent CHESS HISTORY & DEVELOPMENT. Therefore significant opponents of champions, or opening system pioneers (like Duncan Suttles), are also represented. It should comprise opening, middle game (how to proceed after the opening), and endgame samples to satisfy the most enquiring minds. To this end, an array of filters is provided with some serious sophistication. Please share my suggested list to get the most from CT&PM efficiently and manageably. Please also try my ODDS RATINGS if you run a club. It should surprise anyone who does that such  a mathematics actually exists undiscovered for so long. One might be tempted to think that there's no money in it, or that some sorry status quo is being unreasonably defended due vested interests! Maybe? Does that sort of thing really happen? Only according to "conspiracy theorists", they say!

    Just downloaded the latest update of CT&PM from

    http://www.swissimmaculate.com/about-us

    to check the site, and was offered WinZip rather than Extract All... by my new laptop. So I uninstalled WinZip and the Right Click worked as expected with Extract All... as usual. This may be of help to someone with the same problem. You will find the database suggested in my previous post readily available to be compiled by CT&PM, so that chess research will be at your fingertips. The PGN file supplied is in descriptive notation with diagrams, and contains 33813 games. After compilation, you can create the algebraic version without diagrams as required by viewers, or Crafty GUI. These games were compiled while developing and testing the CT&PM APP (Keyboard only), which is now complete. Any bugs I discover over time will be removed from update to update.

    "Chess Translator & PGN Manager" is a wish of mine become a reality, and I use it frequently for many of its features. So...it hasn't taken long to realize that the refined text editor utility used throughout was incompatible with Roster Filtering. Very unfortunate. For those who have compiled the descriptive notation PGN plus diagrams (opening definition position & final position), it should have been possible to produce a PGN file (algebraic or descriptive + options) of any of the pioneers who have proved their mettle for recorded history. They have consolidated our knowledge of the game (and their opponents, of course).

       Presently the APP crashes if you try defining Roster Filters (without harm to your database). Apologies for this temporary inconvenience. Other filters will work. You will find that endgames or openings will partition the entire database (without duplication) in labeled folders, when the entire defined set is selected. The set of opening variations is extremely useful, and will produce the chronological development of each system from the provided PGN. The Cartesian product of all defined endings will likewise reward the student or the researcher planning a publication. Only the most reduced "endgame" (pieces not pawns) define the partitions for each game. Endgames with no pieces at all will produce every game that terminated in a pawn ending. Games with 3 or more identical pieces form their own partition. Games ending with few pieces removed will reveal quick debacles, like winning combinations or mating attacks, for the study of tactics. Of extreme utility for prospective champions will be rook endings. These constitute the most difficult and the most common of endings. Even the endgame virtuoso Jose Capablanca found the need to study a thousand to get a grip. Thereafter he commended Akiba Rubinstein for his virtuosity in this department. Rubinstein learned the game at 22, and after recognizing their importance, studied major piece endgames to return a real contender for the title. When the next version, bug removed, appears (I will give notice here, the Most High willing) you will be able to extract all of Rubinstein's games, compile the database in another folder, and then extract the Cartesian product of major piece endgames of interest. The process can be achieved using both filters simultaneously, but much more slowly.  The process requires many passes of the database being scanned. Meanwhile, I hope your chess is much improved by these facilities. Endgame play elevates the power of the champion, but is sadly being neglected by real and virtual (increments which grossly multiply play rates) guillotine conditions. A maximum of doubling the rate after 40 moves should be mandatory, in my opinion. This corrects the situation (3 seconds minimum per 2 minutes clock). My studies have revealed that half of the piece strength occurs on average at 40 moves (80 half moves). This was the traditional clock time addition cutoff before Fischer clocks appeared. Unless I'm sadly mistaken, Bobby Fischer would have blown up over the mismanagement of his invention! Inequity was a major cause of his protestations, however misguided his extreme specialization may have made him in the end. Only a "Jack of All Trades" is particularly well rounded, I feel.

       I will continue testing until the expiry date before reissuing. Regards to all, JC.

    Chess Translator has expired. The next issue will last 2 years, and was due but, while fixups have been made, a small delay proves expedient. I stumbled upon Phil Harvey's exiftool, and it has offered me a startling idea to simplify the use of "Chess Translater & PGN Manager". By dragging a (downloaded of other) PGN file over the CT&PM icon (or shortcut), a folder may be created which contains a selection of files providing all sorts of information about the input PGN file and its games. Timing! I am working on this presently, and proves a relatively simple operation soon to be finished.

    This is the ReadMe text accompanying the new "Chess Translator & PGN Manager" (CT&PM) Version 3.03, soon to be released:

    Activation.

       Change the .m4a extension in filename.m4a to filename.exe, & ignore the warning from Windows. The thumb nail should change when successful. Double click the APP icon and follow the rest of the installation instructions as supplied by the APP. Alternatively, create a SHORTCUT, set to maximise, and delete the directory path string shown in the "Start in:" box, then hit the buttons "apply" and "OK".

       Now copy the APP or its SHORTCUT to the directory containing a PGN file downloaded from the net. Drag the PGN file icon over the APP icon, or its SHORTCUT. A folder with the same name as the PGN file will be created, and filled with files and folders. These can be used to supply all sorts of "intelligence".

       The ALGEBRAIC PGN files only (not the DESCRIPTIVE, nor PGN with BOARD POSITION DIAGRAMS) will work in viewers like PGN Mentor. Crafty GUI can also be used, and will play on if you wish to unravel tactics through experimentation. The DESCRIPTIVE PGN is mostly provided to mirror the ALGEBRAIC PGN, but with added ECO SUBVARIANT POSITION reached, and FINAL GAME POSITION reached, as rudimentary BOARD POSITIONS.

       All DESCRIPTIVE PGN is correspondingly GAME NUMBERED for CROSS REFERENCING with the associated ALGEBRAIC PGN, to assist with searching for specific ENDINGS or OPENINGS, TACTICAL DEBAUCLES, CHECKMATES, etc.

       Open a PGN file using each of PGN Mentor, Crafty GUI, and Notepad once, to associate these APPS accordingly in Windows, and thereafter Right Click a PGN file icon & "Open with..." will let you make a choice between these APPs. You can make any you prefer the default at any time with the "Choose default program..." option.

       With familiarity gained as described above, some may wish to venture into uncharted territory. With CMD.exe, or CT&PM started normally by double clicking the APP icon, whole folders of PGN can be knitted, or selected from, to create desired collections of games, or perform other complex tasks beyond the DEFAULT COMMAND SEQUENCE offered above for simplicity. The supplied PGN file, "BCE (algebraic) 34137.pgn", will take hours for DEFAULT PROCESSING, but will supply a DATABASE of games outlining the entire historical development of CHESS THEORY. This DATABASE is in the form of the folder "!_CT&PMData". The associated "intelligence" will be extensive. As it is supplied, it is a sort of "Basic Chess Endings" a la Reuben Fine, created in such fashion from DEFAULT PROCESSING results. It covers samples of Pawn vs Pawns all the way to NNBBRRQ vs NNBBRRQ, 834 different final position combinations in total.

       If you don't trust this software, buy a cheap Windows 7 Laptop and test it. Trust me, if you are a serious chess player reaching for the stars, it will be worth every penny.

    Enjoy.

    Sincerely, JC.

    P.S. Check version numbers from time to time for bug fixes or enhancements.

    An apologetic note to those interested...CT&PM has fallen over with further testing, and mods are taking a while to accommodate. I will supply a notice here when uploaded to:

    http://www.swissimmaculate.com/

    At this point, here's what will be generated when a PGN file icon is dragged over the ""! Chess Translator.exe" icon in Windows Explorer - a folder with the same name as the PGN file minus extension, containing:

    1. algebraic PGN file (formatted, with game numbering tag and preceding positional opening sub-variant ID comment)

    2. descriptive translation PGN file (including board positions for above ID and also the game conclusion position, for non viewer inspection which can be cross referenced with the former by game numbers)

    3. as 1 but sorted in movetext order for searching variations rather than chronological input order.

    4. as 2 but, again, reordered.

    5. a concise algebraic text file of ordered variations for referencing by game numbers, with accompanying pgn.

    6. WHITE's concise opening repertoire based on knowing (only) all games contained in the input PGN, and conclusion (+ = or -) following the FEN's for the odd's games and the normal initial position, with accompanying PGN for cross reference.

    7. BLACK's concise opening repertoire likewise. Note: Bobby Fischer's games prove to be unusually consistent thus analyzed...as though he never forgot a game that he played!

    8.  All annotated games with more than rudimentary comments such as {...}, in both formats

    Algebraic & descriptive versions, as above, will be the following folders of sets of PGN files for:

    9. a partitioning into 48 opening categories {Alekhine's Defence, Benko Gambit, Benoni Defence, Bird's Opening, Bishop's Opening, Budapest Gambit, Caro-Kann Defence, etc.} based on positional ID's.

    10. a partitioning into 2011 opening sub-variants (positional ID's).

    11. a partitioning into 82 "endgames" = piece (not pawns) combinations possible (from the initial position to "3 [or more] of a kind", and no pieces at all being "pawn endings"), defined by the most "reduced" (advanced in the hierarchy) found during the game for either side.

    12. a partitioning into 82 x 82 "endgames", one for each side, as for 11.

    and collections of the following types of endings, where each PGN file in the folder will represent any game which, throughout the game for either side, includes a piece combination represented by:

    13. Pawns only

    14. Minor pieces only

    15. Rook & minor pieces

    16. Queen and a minor piece

    17. Major Pieces only.

    Constructing a command sequence to ensure this set of PGN files will be automatically created for any input PGN file proves somewhat time consuming to implement and test.

    Jonny resigned after 47. Ra7. I don't know about you, but I needed Crafty to spit out the remained of the game (or one such) to know why. Kasparov in 1997 lost to the machines. I guess we must accept that the computer's event horizon has outstripped human ability. It means that we cannot avoid tactical mistakes that computers will see but we can't. What is surprising is that they are playing openings our champions have largely abandoned as drawn, and winning! I hope my work will help revitalize these fascinating openings again. It can place relevant research into the hands of imaginative players who find themselves somewhat bored. "Chess is not only knowledge and logic" in Alexander Alekhine's opinion. Anyone who claims to be a master of Chess must have a dog by that name. Even the immortal opening invention of Gioachino Greco has been championed by Champions, like Boris Spassky, and with success against Bobby Fischer himself. Plainly, the assessments of opening books are a rough guide at best, when it comes to the latest wrinkles. Computers are having a last word concerning established doctrine! Then, the tactic of becoming unpredictable regarding opening selection, and on mass generally...it's got to happen some day. When was the last time that the World Championship was decided by a Giuoco Piano?
