Dear Nimzo_3d users,<br /><br />I have added some more features to the full screen layout.<br /><br />There is now an optional engine analysis window<br />with an optional toolbar.<br />The full screen window layout is now saved and restored.<br /><br />The opening training feature can now be used in full screen mode,<br />in the same limited way as in 3d graphics mode.<br /><br />There were a couple of minor bugs in the switch to and from<br />full screen mode which I have fixed.<br /><br />There is also an < Adjourn game > feature so that<br />you can save and restore games with their clock times.<br />This is accessed from < Main menu > < Games ><br /><br />Previous links for the program now point to the<br />new version 4.2<br /><br />I have also made some updates of various versions for exiting users,<br />which can be downloaded from the following links -<br /><br />English language version 64-bit - Size 21 Mb<br /><a

position after 37.b4. However, 37.b4? - as well as the preceding moves 35 and 36 by both sides - constitute errors that alter the result of the game (see the attached PGN file). I shall later return to the position with the pawn still on b3.<br /><br /><b>37...Kg7?</b> <br /><br />Shereshevsky correctly observes that Black’s counterplay should be associated with the advance ...f7-f5. This plan was already appropriate at this moment and remained so over the next two moves.<br /><br /><b>38.b5? </b><br /><br />This natural-looking continuation is not discussed by Shereshevsky, yet it proves to be a decisive inaccuracy. White should instead have played <b>38.Rb7!</b>, which effectively neutralizes the thematic break f7-f5.<br /><br /><b>D. 9-1</b><br /><br /><table border='0' cellspacing='0' cellpadding='0'> <tr> <td

In the 2022 English edition, Shereshevsky substantially revised and corrected many of these mistakes, yet several serious errors remain. In <i>Associative Thinking </i>Shereshevsky apparently continues to believe that after 42.b5 Rb4 White wins. In fact, black holds the game with precise play.<br /><br /><br /><table border='0' cellspacing='0' cellpadding='0'> <tr> <td width='40' height='40'><img src='/yabbfiles/Chess/e40.gif' width='40'

and afterwords in his book that he had missed the win by 42.b5 instead of 42.h5. Shereshevsky points out in Endgame Strategy that today’s computer programs easily detect a ‘hole’ in the half century old analysis of Polugaeyvsky - 42.h5 gxh5 43.b5 Rf4! 44.f3 h4+ 45.Kf2 h3! 46.gxh3 e4 47.Ke3 exf3! with a draw. <br /><br /><b>42...Rb4</b> <br /><br />Both Polugayevsky and Shereshevsky believed that this is a decisive mistake.

Polugayevsky gave 48…Rb4 a double exclamation mark and described it as extremely subtle.

Strategy Shereshevsky reproduces fully the following analysis of Polugayevsky:  “However, after 45...e4! (also possible is 45...Rb2) the tempting 46.Kxh5 leads to a draw after the quiet 46...Rb4!!, and White is condemned to fight without his king, because it cannot cross the “mined” 4th rank. (…) Nor is anything changed by 47.g4: the advance g4–g5 is not possible because of the reply 47...Rb5+!!".<br /><br />In fact, in this analysis of Polugayevsky the only correct move is 45...Rb2. 45…e4? loses after 46.b7! Rb5 47.f4 e3 48.Kg3! e2 49.Kf2! Rb2 50.f5+–. After 45…e4? 46.Kxh5? the move 46…Rb4 given double exclamation mark by Polugayevsky, loses to 47.g4 or 47.Rb7+. Instead of 46.Kxh5?

Initially, it's amusing to see Gemini "chicken out". Further reflection brings the realization (as noted in a number of comments) that this example shows the limitation of using a Large Language Model AI in an area where its training is inadequate.<br /><br />I believe a few comments mentioned hallucinations, which reminded me of an October 2025 interview of ChessBase's Matthias Wüllenweber, where he says AI "struggles with the chess middlegame due to its hallucinations. Chess is simply too complex."<br /><br /><a href="https://en.chessbase.com/post/in-chess-ai-fails-due-to-its-hallucinations-an-interview-with-matthias-wuellenweber" target="_blank">https://en.chessbase.com/post/in-chess-ai-fails-due-to-its-hallucinations-an-interview-with-matthias-wuellenweber</a><br /><br />Imagine my surprise when, a few weeks later, the latest version of his company's flagship product, ChessBase 26, is announced to have an AI feature that will take a middlegame position and suggest a plan. In describing the features of ChessBase 26 in a November interview, Wüllenweber presented the AI feature in a tone of voice that suggested to me that it was added partly for entertainment value. In the example he showed, the AI did present a reasonable-looking plan, although at one of point Wüllenweber warned about the possibility of hallucinations.<br /><br /><a

that remain unexplained, chess literature often attributes this position to Kling and Horwitz and dates it to 1851. In fact, no such position appears in their <i>Chess Studies or Endings of Games (1851)</i>, in <i>Chess Studies and Endgames (1889)</i>, or in the weekly journal <i>The Chess Player (January 1851-December 1853)</i>, which Kling and Horwitz co-edited. If Kling and Horwitz had actually analyzed this position, it would have been revolutionary in the 19th century, as it would have completely refuted Philidor’s principle that the defender’s rook must not leave the sixth rank before the pawn advances. As noted above, it was first analyzed - with Black to move - by Frink and Rabinovich in 1926.<br /><br /><b>3…Rh1!</b><br /><br />The only move. As we saw above, with the king on the short side, Black has several ways to achieve a draw. With the king on the long side, a flank attack is the only way to achieve a draw. Frink considers the continuations 4.Rf8 (a) and 4.Kf7 (b) here.<br /><br /><b>a) 4.Rf8 Re1!=.</b><br /><br />The only move - Black is saved by a back-and-forth rook maneuver. As we saw above, with the king on the short side, a flank attack from the long side, transposing to the Tarrasch position of 1906, is also sufficient for a draw. However, here, with the king on the long side, a pawn attack from the rear is the only way to achieve a draw. White cannot strengthen his position. <br /><br /><b>b) 4.Kf7 Rh7+ 5.Kg6 Rh1 </b><br /><br />Or 5...Kd7. <br /><br /><b>6.Kf7 Rh7+ 7.Kg6 Rh1 8.Kf6 Rh6+ 9.Kf7 Rh7+ 10.Kf8 Rh8+ 11.Ke7 Rh7+ 12.Kf6 Rh6+

Berger would say that it is lost for Black on two different counts-namely, Black cannot occupy the sixth rank with his Rook (because 1...RR3; 2 PK6 wins); and again, the Black King is on the wrong side of the Pawn, according to Berger”. <br /><br /><b>1...Kd8!  2.Kd6 Rd1+ 3.Ke6 Re1=</b>. Position D. 1 after 1.Kf6 Re1 arose.<br /><br /><b>Chéron’s later claim</b><br /><br />Although Chéron was aware of Frink’s position from The Chess Amateur, he nevertheless published it under his own name in 1927 <i>(Traité complet d’échecs. Finale - Début (1939, no. 147, p. 106)</i>. Only in the <i>Errata</i> to his book did he acknowledge that Frink had discovered the solution before him. However, in all subsequent editions of his work, Chéron no longer mentioned Frink’s name in connection with this move and instead claimed authorship of the solution to position D. 1 (see, for example, no. 145 in the latest edition of <i>Lehr- und Handbuch der Endspiele, 1960, Vol. 1, p. 87</i>). Furthermore, both in <i>Nouveau traité complet d’échecs. La fin de partie (1952, Nos. 186-195b, pp. 170-182)</i> and in the subsequent German editions <i>(Lehr- und Handbuch der Endspiele, Band 1, Turm-Endspiele, 1st edition, 1952, Nos. 142-153, pp. 82-90; 2nd edition, 1960, Nos. 142-153, pp. 82-90)</i> he presents the solutions as if they were his own (except No. 147, Kopaieff). In fact, none of the solutions to positions no. 142-153 originally came from Chéron (except no. 146 in the 2. edition of the Lehr- und Handbuch, p. 87).<br /><br /><b>Postscript</b><br /><br />Orrin Frink made numerous other important contributions to rook endgame theory that are now largely forgotten.
