  • From marek kwiatkowski on Ceskoslovensky Sach 2023

    In the Gonzalez’s study (a very smart and twisted puzzle) there is a subtle duel: white King and white Rook against black Bishop based on a witty static relation Rh1 and Bh2 against Kg2 and Rh3 supported by a surprising added in accurate way possible relation in endgame KR/KP. A very complex idea in a perfect form. Maybe without the first 1… Kg2 or even 2. Re1 Rh3 (the Key 1. Kb8 !!) : 1/2 Prize. 🙂

      The author should also consider 20… Bb7(c6), as main line, (instead of 20… Bf3 21. Kf4 … with a strange final 22… Rh3 23. Rg1#) and the thematic end: 21. Rhb1(c1)! +- (the main goal: Rook h1 attacks Bishop, at last!).

        Serhiy, each composer wishes to create an immortal classical work. Louis Gonzalez is very close to have it.

          Everybody knows that Luis Gonzalez is a syzygy tablebase miner and he took this position from there in one click – it is the longest win with this material. Then he added a pawn to hide his crime. Idiot at work.

      • From marek kwiatkowski on Ceskoslovensky Sach 2023

        The relation Rh1 and Bh2 against Kg2 and Rh3 is seemingly static, and the fact that Rh1 doesn’t play (physical moves) in the main line is impereceptible.
        Such a “static” pieces happen: https://eg.org.ua/chessgame/didukhs-0541-13f1e4/ 😉

    Polasek participated with analyzed positions. Gonzalez sent in another database rubbish. Obviously, computer and databases are not enough to become a composer.

    Positional draw with a promoted N vs RN is not new. Pogosyants’s promoted knight worked even more.

    Five studies have bad initial positions with at least 5 major pieces and only one pawn or no pawns at all.

  • From Jan Sprenger on Ceskoslovensky Sach 2023

    A lot of prizes, but none of them exciting.

    In Pasman and Tkachenko’s studies, which I find among the better ones, I would have omitted the first and second pair of moves. The position is more natural and the additional moves do not add thematic content. Perhaps even leave out the third pair in Pasman’s study so that you get a miniature. On the other hand, the f8=N mechanism in Pasman’s study looks only mildly original, so perhaps an introductory sacrifice with thematic try is needed to add some content.

    Hlinka/Kekely/Arestov managed to construct their pin stalemates cleanly, but the preceding play has a lot of strange analytic lines. I am even unsure that it is sound. The line 5… Rb7 … 9. Kd4 can be continued with 9… Rd8+ 10. Nd5+ Kg2 11. e7 Rc8 12. Nc7 Bb7 and now transition into the lost endgame BN vs RB with opposite-color bishops looks inevitable.

    Minski & Nielsen have a cool idea, but I am close to throwing Gurvich’s book at them (economy of material).

    What the other prizes are for I cannot even imagine. But I like the first HM by Arestov and Hlinka. 6. Rf6!! (delaying the Siegfried rook action) is for the books and also the rest of the play is instructive.

    • From Steffen Nielsen on Муха в этюде

      Always brave to have a go at improving the classics. From a solving/promotion perspective Harold’s is still the best (published in a regular newspaper as well).

      Having pawns on e2 and g2 means the bishop-was captured on f1. I know Martin, for instance, is not bothered by this stuff, but I suggest putting the pawn on g3. Makes it slightly more natural to me.

      2024/03/15 at 9:17 am
      • From marek kwiatkowski on Муха в этюде

        It is also possible to move all pieces left, to avoid the capture of Bishop f1.
        3. Kg1 is almost same like 3. Kh1, but “almost” makes a differnce (sometimes huge). 🙂
        The Serhiy’s interpretation is very proffesional. In fact, there is a double excelsior (only 5 pieces!).
        For this, it seems to be necessary to add the important variant 2.. Kd3 3. g5! fxg5 4. e5 +- to the solution and to set Serhiy as co-author of this version.

        2024/03/15 at 2:58 pm
        • From marek kwiatkowski on Муха в этюде

          Regarding to the Excelsior theme: it seems to be welcome (maybe a condition even) that the thematic Pawn by a moment is not a “passed pawn” only.
          BTW. A question to Serhiy:
          Why login from Chess Study Art doesn’t work in your database site?

      • From Didukh on Муха в этюде

        I am not bothered by the e2-g2 pair either. Excelsior of the g-pawn and its switchback Qg2# is not a big deal but still it is nice and I’d prefer to keep it. Another little detail that I like in Marek’s version is sacrifice of the g-pawn after 2…Kd3 3.g5!

    • From Didukh on Муха в этюде

      This night I’ve been solving studies with bishops from Steffen’s “Endgame Labyrinths” and ran into no.201 by trio YB + KS + VT that was initially awarded 5th prize in the Razumenko 2020 MT but disqualified in the final award. I knew the study was anticipated but couldn’t remember who showed this idea before. So, I marked/liked Ornstein’s study in order not to forget it again.

          The line where Bishop and King swap functions is important, indeed. Now this version is in the database instead of Ornstein’s version.

          I have no idea why you call black pawns “stinking insects”.

      • From marek kwiatkowski on Муха в этюде

        It is a masterpiece! Both pawns h6 and d4 are “stinking insects”. The first move 1.Bf7! realizes a prelimanry plan to stop the main defence idea: h5 gxh5 (a wrong Bishop). White King can only stop Pawn d4 (impossible to capture there) and starts (3. Ka3!) a “crazy” (difficult to understanding) idea (the main plan) to exchange functions of King and Bishop. It is incredible that it happens, but only thanks to a wonderful, very long (without any minor duals !) and deep (full of zugzwangs) maneuver.
        The move 17.. h5! (at last!) is late.

  • From marek kwiatkowski on Муха в этюде

    Serhiy, mayby it would be better to leave Leonid Kubbel alone, and to use your rare gift for improving, somewhere else.
    For example, in the two followig twin miniatures, there is “a real moving and irritating fly” (f6 <=> e5).

    Both the positions look like classical ones, but they don’t appear in your database (as parts too!).
    A try to join both:
    https://pzszach.pl/wp-content/uploads/2022/04/22-XI-2022-2775-%E2%80%932780.pdf
    was ignored by the judge (Jan Rusinek). The second attempt (without moves 1.Nxd8 Rh4+ 2. Ke3) was rejected again (Jan Timman). In fact, the initial play is not that exciting, to seduce someone, but it would be problematic to cut and leave it as twins with the same initial play 1.a6! Bxa6 2. Be2 Re4+! 3. Kxe4 Bb7.
    Maybe anybody can solve the problem of this “irritating fly” in a better way.

    2024/03/06 at 3:32 pm
  • From Didukh on Муха в этюде

    In other studies by Kubbel the black queen often doesn’t move. So, either his technique wasn’t good enough or his conception of beauty was too primitive and he didn’t care about black pieces.
     
    The black queen has to move in the next studies because she is an important piece in the ideas expressed.
     
    1. The checkers theme with two black queens captured.

     
    2. The famous study that uses Qe7 to defend Ne3 and mate the black king. This study needs a quiet move 1.e7! that decoys the queen.

      Coming back to the Thomas’s text, there is still the main his question regarding to originality of Marek Halski 1st Pr Ceskoslovensky Sach 2022.
      The judge is the (next here!) great composer: Martin Minski (“Beauty doesn’t have to be complicated.”)
      It would be good to know and fully respect (in advance!) his finall decision.

      There are different ways to find a beauty. Sometimes it can be many versions or improvements, because it can be very problematic to select this only one.

        It can be very tricky indeed to know where to draw the line.

        But there are places to submit versions and improvements out of competition. Here for instance (or in the original source as “out of competition).

        In my own work I have a couple of study versions that should not have been submitted:

        Arestov=P Slumstrup Nielsen=S — (+0440.33b1a3)

        Nielsen=S Arestov=P — (+3401.30g3g8)

        I also have a couple of partially submitted studies I am unsure about, like this

        Slumstrup Nielsen=S — (+3540.20b5b3)

          And what about a hypothetical situation. Your (effectivelly provoked by Sergey and mentioned above) lovely version of the 1st Prize Magyar Sakkvilag 2023 would be created by another composer (maybe impossible, but it is still only fantasy) and it takes 1st Prize. The serious judge knows your earlier version (negative commentaries too!), but he very likes only this new one, and in the name of author your name is missing.

      It looks like Hlinka and Halski don’t know Kiryakov’s win study from EG 2021 with this movement. Some people are so busy composing own studies that they have neither time nor interest to see studies by others.

    A new version with a more pointed finish. I would like to sacrifice a White knight on g6 in the intro (to begin with equal material), but it proves difficult. Will continue to look.

    Interesting fact. Kubbel has 50 studies in the database with a white pawn on the 7th rank in the initial positions. And Marek Kwiatkowski has only 12 studies (2 of them are versions). An extraodinary artist and study expert! 🙂

    But it’s acceptable for Marek Kwiatkowski to capture 3 major white pieces that didn’t make a single move. However, he knows what is unacceptable for Kubbel.

      Yes, I remember I had a stalemate at one point. But of course the 2xf4-idea must win.

    2024/02/23 at 11:32 am
    • From Didukh on Magyar Sakkvilag 2023

      No, it’s bad. Awful look, no links between the parts of the study, no economy of time.

      2024/02/23 at 2:30 pm
    • From Steffen Nielsen on Magyar Sakkvilag 2023

      Yes, I think it is good. White already has four pieces so adding an extra Black one makes no difference. The second phase doesn’t seem like such a long desert walk this time.

      Still, it is kind of empty. It is the danger of these pin/unpin/chaotic studies. Very difficult to pick a quick pointed finish when there are still 6-8 pieces on the board.

      And very difficult to make a meaningful finnish where the pieces leave the field naturally. That is why this ChessStar study stands out:

      Slumstrup Nielsen=S — (=4440.13e3h6) A

      You can’t win the lottery every time.

      The first phase in my study for MSV is surely more memorable than the one for Masimov. Twice f4 is extremely pleasing to me. I worked so long to make a good finish (there is also the option of having the White queen on h7 and Black’s on c7), but I admit I had to settle.
