Honza Cervenka
Member since Sep-04-02 · Last seen Dec-02-21
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.)

   Honza Cervenka has kibitzed 10964 times to chessgames   [more...]
   Nov-29-21 S Halkias vs B Zueger, 2009
Honza Cervenka: 13...0-0 is surprising and hardly reasonable decision. 13...0-0-0 looks much safer and more natural continuation. But the decisive mistake was 26...Qg5 allowing white to exploit tactically loose position of major black pieces for pretty finish.
   Nov-26-21 Bronstein vs Evans, 1955
Honza Cervenka: 40...f6?! and 41...a4? let white slip off the hook. 40...f6 was unnecessary, 40...a4 was winning easily, and instead of 41...a4 black should have played 41...h5 to avoid perpetual.
   Nov-26-21 R G Wade vs M Aaron, 1961
Honza Cervenka: <perfidious: The error came before 14....c6; after 14.Nh4, Black must lose material however he plays.> Well, 14...Nf6 15.Bxb7 Rb8 16.Bg2 was definitely lesser evil. Now 16...e4 can be quite double-edged but black has other moves as well.
   Nov-26-21 Bronstein vs Saitek Brute Force, 1994
Honza Cervenka: <17 ...g6; 18 ♗xf7+, ♔xf7; 19 ♕xh7+, ♔f6; 20 ♕h6 and I didn't see an immediate end.> 20.Be5+ (instead of 20.Qh6) 20...Kf5 21.Qf7+ Kg5 22.Bf4+ Kh5 23.Qh7+ Kg4 24.Qxg6+ Kxf4 25.Re4# is quite convincing finish.
   Nov-25-21 J Penrose vs Robatsch, 1961
Honza Cervenka: 32...Qc8 could prolong resistance.
   Nov-25-21 Flohr vs L Barden, 1961
Honza Cervenka: 38...Kg5 would have been better.
   Nov-25-21 Bisguier vs J Penrose, 1961
Honza Cervenka: 29.Rxc6 bxc6 30.Bd6 f6 31.f4 was worth of consideration.
   Nov-25-21 L Barden vs Bisguier, 1961
Honza Cervenka: Draw seems to be quite premature here. White is clearly better in final position.
   Nov-25-21 J Littlewood vs Gligoric, 1961
Honza Cervenka: <Black plays 34...Nc7 but this leaves his bishop short of squares. His pieces get in a right old tangle and he drops one!> In fact, Bishop was not trapped. It was possible to play 35...Bxf4 36.Nxf4 Re4 winning the piece back. Also 36...Ba1 was still sufficient, as ...
   Nov-24-21 Botvinnik vs Gligoric, 1961
Honza Cervenka: It seems to be that both players were so much well aware that the ending is drawish that they lost concentration towards the end. Gligoric's 99...Bg7?? was a howler but Botvinnik already reconciled with the fact that there is no win in the position missed his chance to win ...

  offramp: <JimNorCal: It's a classic look> There is something wrong with it. Mr Winawer should look towards the centre of the page.

I had that problem with my avatar: Mr Pike was looking to the left, off the screen. I asked Daniel and he reversed the photo.

Now Mr Pike looks to the centre. This is regularly done in the newspaper and magazine business.

Sometimes it is done to chess scenes, and results in a black square at "h1" (a1 in real life).

Black to play and win

Premium Chessgames Member
  Honza Cervenka: <OhioChessFan> In your diagram 1...Kf1 is apparently the only reasonable move. In my diagram 1...Kf4! 2.a5! Ke4! is the solution. 1...Kg4 with idea to take both white KS Pawns is insufficient for 2.a5 Kxh5 3.Kd2 Kxg6 4.Kc2 h5 5.Kb2 h4 6.Ka3 h3 7.Ka4 h2 8.a3 with inevitable stalemate. Also 1...Kf4 2.a5 Kg5 fails to win due to the same stalemate trick. After 1...Kf4! 2.a5! Ke4! white is in zugzwang, as any Pawn move leaves him without that stalemate defense, which indirectly covers white KS Pawns, and after 3.Kd2 Kf3 4.Kc2 Ke2 5.Kb2 Kd2 6.Ka3 Kxc3 7.Ka4 Kd2 (of course not 7...Kb2 8.a3 with stalemate) 8.a3 c3 etc. there is no stalemate, as white can play 9.Kb3.
Premium Chessgames Member
  OhioChessFan: Yes, Kf1 is the only move. I can't believe I missed the stalemate in yours. Oddly enough, I knew if I was missing something-which I was "sure" I wasn't, I knew Kf4 had to be the puzzle move.

Well, I used to play football (soccer) some thirty years ago but this is a bit different kind of sport than "American football", and unfortunately I never was in Clemson. The nearest place to Clemson I have ever visited is Mexico City....:-)

  Honza Cervenka: Today I have played quite interesting Rook ending:

[Event "Prague team ch"]
[Site "Prague"]
[Date "2020.02.10"]
[Round "?"]
[White "Cervenka, Jan"]
[Black "Steiner, Juraj"]
[Result "1-0"]
[ECO "B35"]
[Opening "Sicilian"]
[Variation "Accelerated Fianchetto, Modern, 7.Bc4 Qa5"] [PlyCount "113"]

1. e4 c5 2. Nf3 g6 3. d4 cxd4 4. Nxd4 Nc6 5. Be3 Nf6 6. Nc3 Bg7 7. Bc4 Qa5 8. O-O d6 9. f3 O-O 10. Qd2 Nxd4 11. Bxd4 Qb4 12. Qd3 d5 13. Nxd5 Nxd5 14. Bxg7 Kxg7 15. Bxd5 Qxb2 16. Rab1 Qf6 17. Bxb7 Rb8 18. Bxc8 Rfxc8 19. Rxb8 Rxb8 20. Rd1 Rb2 21. a3 Qb6+ 22. Qd4+ Qxd4+ 23. Rxd4 Rxc2 24. Rd7 a6 25. Ra7 Rc6 26. a4 e5 27. a5 h5 28. h4 Kf8 29. Kf2 Kg7 30. Ke3 Rc3+ 31. Kd2 Rc6 32. Kd3 Kf8 33. g3 Kg7 34. f4 exf4 35. gxf4 Rf6 36. Ke3 Rc6 37. e5 Kf8 38. Kd4 Rc1 39. Rxa6 Rh1 40. Rf6 Rxh4 41. a6 Rh1 42. Kc5 Ke7 43. a7 Ra1 44. Kb6 h4 45. Kb7 Rxa7+ 46. Kxa7 h3 47. Rc6 h2 48. Rc1 Ke6 49. Kb6 Kf5 50. Rf1 f6 51. exf6 Kxf6 52. Kc5 Kf5 53. Kd4 Kg4 54. Ke5 Kg3 55. Kf6 Kg2 56. Ra1 Kg3 57. Kg5 1-0

42.Kc5 was a mistake which could allow black escape from lost position after 42...h4! 43.e6! (43.a7 Ra1 44.Kb6?? h3 even loses, though 44.f5 Rxa7 45.fxg6 Kg7 46.gxf7 Rxf7 47.Rb6 leads to draw) 43...Rc1+ 44.Kd6 Rd1+ 45.Kc7 h3 46.Rxf7+ Kg8 47.a7 Ra1 48.Kd8! h2 49.e7 Rd1+ 50.Kc7 Rc1+ 51.Kb6 Rb1 52.Kc5 Rc1+ 53.Kd4 Rd1+ 54.Kc3 Rc1+ 55.Kd2 Rd1+! (this deserves diagram, both Rooks are en prise but none can be taken)

click for larger view

56.Ke2 Re1+! 57.Kf2 (now 57...Rf1+? would be a grave mistake for 58.Kg3 and white wins but now black can finaly promote his h-Pawn, as the Rook from e1 covers else threatening e8=Q#) 57...h1=Q 58.a8=Q+ Qxa8 (58...Kxf7 is still not an option for 59.Qf8+ Ke6 60.e8=Q+ +-) 59.Rf8+ Qxf8 60.exf8=Q+ Kxf8 61.Kxe1 =. Fascinating line.

Of course, correct continuation was 42.e6! with idea 42...Ke7 43.exf7! Kf8 44.Kc5 +-

  Honza Cervenka: Experience from the Chessgames Challenge game Y Shulman vs The World, 2007 was quite useful for me today:

  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!

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.

  Fusilli: <Boomie> Oooh... cool! Opposition, opposition! The one with the last opposition laugh wins... or draws.

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

Premium Chessgames Member
  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.

  Stonehenge: <Honza>

Is this maybe the same player?

Gyorgy Meszaros

Gyula Meszaros

Premium Chessgames Member
  Honza Cervenka: Yes, it is Gyorgy Meszaros. attributes this game to Gyula Meszaros but it is apparently a mistake, as IM Gyula Meszaros was born in 1967.
Premium Chessgames Member
  Stonehenge: Thanks, I've merged the player files.
Premium Chessgames Member
  Stonehenge: Alexandre Van Hoorde vs J Fichtl, 1954 has Ghent (Gent) and Edouard van Hoorde.

Premium Chessgames Member
  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.
Premium Chessgames Member
  Stonehenge: Thanks, it's fixed:

BEL-CSR (1954).
