Honza Cervenka Member since Sep-04-02 · Last seen May-17-22 I live in Stredokluky (a village near Prague, Czech republic). I play both practical and correspondence chess. My rating in practical chess (Czech national ELO) oscillates somewhere between 2010 and 2060, in correspondence chess I have rating 2155 (my best was 2220 in the middle of 90's). I have no special favorite player but I like to view good games of old masters (Tarrasch, Schlechter, Chigorin etc.)

May-17-22 Hecht vs Suttles, 1969   Honza Cervenka: <goodevans: I don't see how Black makes progress after 102.Nf1 either.> 102.Nf1 Bg6 103.Ne5 Bf5 is a problem here, for example 104.Nf3+ Kh5 105.Nd4 Be4 106.Ne6 Bd5 107.Nd4 g4 etc.      May-16-22 J N Berger vs J Schwarz, 1883   Honza Cervenka: 20...g5 was a blunder allowing 21.Bxg5, as 21...Qxg5 leaves Rf7 unprotected, but white missed this oportunity. 31..Kh7 was another grave mistake, and white could play also 32.Rxe6 Qxe6 33.Rd6 with idea 33...Qc8 34.Qh5 +- or 33...Qe8 34.Qd3 +- or 33...Qf7 34.Qe4 +-. Of course,      May-14-22 Yuri L Averbakh    Honza Cervenka: Rest in peace, Yuri Lvovich.      May-14-22 P Ostojic vs Smyslov, 1969    Honza Cervenka: Immediate 19.Rc6 with intention 19...Qb7 20.Qd2! would have preserved solid advantage of white. Playing 23.Ne5 white apparently missed or underestimated 23...Qb6! It was better to play 23.Qe4 or 23.Rc4. Instead of 26.Bxd5 a lesser evil would have been 26.Qxf8+ Bxf8 27.Bxd5 ...      May-14-22 Smyslov vs Benko, 1969    Honza Cervenka: 25...Rd2 allowing 26.Ne5 was a mistake, which was probably already decisive. 28...Kf6 loses instantly but after 28...Kf8 29.Kf1 Rb2 30.Nxe6+ Ke8 31.Nf4 Rxb4 32.Nxg6 the win of white is just a matter of technique.      May-13-22 Portisch vs Smyslov, 1969   Honza Cervenka: 39...d3! 40.Rxe4 dxc2 41.Rxc2 Nd2 42.Re2 Nf3+ 43.Kh1 Nd4 44.Bd5 Nxe2 45.Rxe2 h5 looks like a missed winning chance of black in this game.      May-13-22 K Honfi vs L Schmid, 1969   Honza Cervenka: Black is a Pawn up but there is still a lot of play ahead. If white resigned just there, then it was quite premature decision.      May-13-22 K Honfi vs Smyslov, 1969   Honza Cervenka: White could achieve more in this game than uneasy ending, which he managed to hold. For example, 18.Nd2! with possible continuation 18...Nd8 19.Nc4 Qe6 20.Ne3 a6 21 Rac1 Bg6 22.c4 (diagram) gives white huge advantage. [DIAGRAM] It was also better to avoid exchange of Queens ...      May-12-22 Benko vs L Schmid, 1969   Honza Cervenka: 40.Ned2?? is a bit disappointing final of this quite interesting game. 40.Rc7 Nb5 41.Rxg7 Qxg7 42.Qxb3 Bg6 43.Ncd6 keeps the game equal.      May-11-22 J N Berger vs J Schwarz, 1880   Honza Cervenka: Quite instructive lesson on the theme what awaits a greedy Pawn-eater playing against competent player. 14...0-0 was necessary.

< Earlier Kibitzing  · PAGE 22 OF 22 ·  Later Kibitzing> Feb-29-20    Fusilli: The diagrammed position in the analysis of Cervenka v Steiner is cool! How about a little craziness... imagine if after 56.Ke2 Re1+ 57.Kf2 black, for some reason, doesn't realize he can promote. Instead, he plays 57...Rxe7: click for larger view It may be black's second best move. White has two options. Let's discard 58.Rxe7 h1=Q 59.Re8+ Kf7 60.a8=Q click for larger view Black plays 60...Qh2+ and has perpetual, no question about it. White can never cover checks with the queen without losing the rook. So, let's look at 58.a8=Q+ Kxf7, where black will play for this position: click for larger view Would this be a tough nut to crack? Black would have to keep his king one square from f7 any time that white threatens to play Qxf5 (with the white king on e4 or g4, obviously). But the black king would also have to be on a square where white does not gain the opposition after the exchange of Q vs R, even if white doesn't take the pawn on f5 immediately. I think white should play 59.Qh8, which seems most annoying. Can black still reach the "ideal" position after 59...h1=Q 60.Qxh1 Kg7? click for larger view Probably most annoying is 61.Qa1+. After 61...Kh7 (61...Kf7 62.Qh8 seems too strong) white approaches a square at a time with 62.Qa2 Kg7 63.Qb2+ Kh7 64.Qb3 Kg7 65.Qc3+ Kh7 66.Qc4 Kg7 67.Qd4+ Kh7 68.Qd5 Kg7 and now the fortress fails to 69.Kf3 Rf7 70.Kg4 click for larger view I think this is winning. 70...Rf5 fails to 71.Qxf5 gxf5 72.Kg5, opposition! Other attempts to hold will meet similar exchanges of the queen for the rook with a winning outcome, or white can play f5 for a winning Q v R endgame if black moves the rook away from the f-file. I must say I worked through this without pieces and without chess software, so forgive me if I omitted something obvious! Mar-03-20    Boomie: <Fusilli> < click for larger view > If 70...Rf5 71.Qxf5 gxf5 72.Kg5, then the sneaky 72...Kf8 draws. The winning technique involves maneuvering black into a weaker position according to the table base. https://syzygy-tables.info/?fen=8/6... Mar-04-20    Fusilli: <Boomie> Oooh... cool! Opposition, opposition! The one with the last opposition laugh wins... or draws. Jul-24-20    thegoodanarchist: <OhioChessFan: I've heard passed Pawns must be pushed...> I have been told Yasser Seirawan said <Push 'em, baby!> Sep-08-20    Ron: Here's a game with a Missed Chance: C G M Watson vs D Marotti, 1922 Jan-24-21    jessicafischerqueen: Good afternoon. I wanted to let you know that your latest uploads went through ok on 69/70, but this one here was rejected because it is already in our database: J Lendl vs F Zita, 1964 Jan-28-21    Honza Cervenka: <jessicafischerqueen> That's okay. I am trying to sort and upload just those games which are missing in database but sometimes I can overlook the fact that the game is already there. Jan-30-21    Stonehenge: <Honza> Is this maybe the same player? Gyorgy Meszaros Gyula Meszaros Jan-30-21    Honza Cervenka: Yes, it is Gyorgy Meszaros. 365Chess.com attributes this game to Gyula Meszaros but it is apparently a mistake, as IM Gyula Meszaros was born in 1967. Jan-30-21    Stonehenge: Thanks, I've merged the player files. Feb-03-21    Stonehenge: Alexandre Van Hoorde vs J Fichtl, 1954 http://www.belgianchesshistory.be/t... has Ghent (Gent) and Edouard van Hoorde. Feb-03-21    Honza Cervenka: <Stonehenge> Edouard is correct name. Once again my source attributed by mistake games of a historical player to a current one with the same surname. I have no exact information in which city that friendly match of Belgium and Czechoslovakia took place but I guess that a Belgian source focused on history of Belgian chess should know it better. So it is Ghent. But it applies to the other games from the match as well. Feb-03-21    Stonehenge: Thanks, it's fixed: BEL-CSR (1954). Sep-09-21    juan31: Thanks <Mr. Cervenka >, Gracias Dec-27-21    sachistu: Hello <Honza Cervenka>. Can you tell me what the somewhat cryptic letters 'ar' mean at the end of game notes in Ceskoslovensky Sach? I saw the same two characters ('ar') used at the end of some of the notes in the Trencanske Teplice 1949 tournament book. I did not recognize those letters compared to ones used for Pachman, Louma, Richter, and others. Thanks in advance for any help you can provide. Jan-06-22    MissScarlett: Your pun entry, <One-Cent Magenta>, does it have any special relevance to the game? Jan-17-22    Honza Cervenka: <MissScarlett: Your pun entry, <One-Cent Magenta>, does it have any special relevance to the game?> Yes, there is a connection with the surname of the player with black pieces, as "One-Cent Magenta" or "British Guiana 1c magenta", which is probably the most famous rare postage stamp among philatelists, was autographed by a post office clerk named Edmond D. Wight. https://www.smithsonianmag.com/smit... Jan-17-22    Honza Cervenka: <sachistu> It is quite difficult question, as now I have not access to old volumes of Ceskoslovensky Sach but I guess that "ar" can be Jaroslav Sajtar or Ladislav Alster. I will try to investigate this matter. Jan-17-22    Stonehenge: I believe I have seen "ar" after incomplete game scores, but I'm not sure. Don't take my word for it. Jan-24-22    sachistu: I appreciate your time <Honza Cervenka>. I have quite a number of older years of Ceskoslovensky Sach. Usually, when Alster is the annotator, you will see L.A., or if it is Louma, it will be J.L. or Pachman (L.P) etc. However, quite often I see the lower-case 'ar'. I always assumed this was a group editorial collaboration, but I have never seen any confirmation. Again, anything you discover is welcome and appreciated. Jan-24-22    Stonehenge: Maybe it's an abbreviation of arbitrážní? Just speculating :) Jan-24-22    sachistu: <Stonehenge> Are you suggesting this meant adjudication? If so, I doubt it very much (1) it occurs far too often and (2) it appears with a space between the last move of the game score and the string 'ar'. My experience has been that a note of adjudication appears immediately after the last move, or depending upon the page layout, immediately on the next line after the last move of the score. It's a thought, though. I thought it best to ask someone like <Honza> who was familiar with the language. That's the problem with these 2 and 3-letter abbreviations; you are left with speculation (unless it's quite obvious what was intended). Regardless, thanks for your input as well. Jan-25-22    Z truth 000000001: Could someone be so kind to provide a link to an example of "ar" in an online accessible book or magazine? I'd like to have a quick look - thanks. . Apr-16-22    Ron: Here is game with a Missed Chance by Tarrasch: Mackenzie vs Tarrasch, 1887 A kibitzer gives computer analysis showing 24....Rxg2! wins. Before that move, Tarrasch's pieces are pointing in the surrounding area of White's king, and one might think that there has to be a successful attack somewhere.
