Honza Cervenka
Member since Sep-04-02 · Last seen Dec-12-19
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.)

   Dec-11-19 M Albano vs Matulovic, 1968
 
Honza Cervenka: Order of moves 11 and 12 of white must be wrong. 11.Bg5 and 12.Rfd1 seems to be more plausible.
 
   Dec-08-19 Karpov vs Bronstein, 1971
 
Honza Cervenka: 21...Rxa4 22.Rxa4 d5! could have spared black of all difficulties, for example 23.Nxd5 (23.exd5 Bb4) 23...Nxd5 24.exd5 Qb7 25.Qe4 (25.Qxe5? Rc8 ∓) 25...Qb5 26.h3 (to avoid threatening mate) 26...Rc8 27.Ra1 Rc4 28.Qd3 e4 29.Qe2 Qxd5 etc.
 
   Dec-08-19 V Tukmakov vs Karpov, 1971
 
Honza Cervenka: 16.Nh4 with intention 17.Nf5 was worth of consideration. Of course, 16...Nxe4 doesn't work for 17.Rxe4 Bxh4 18.Rxh4 Qxh4 19.Qxd7 etc.
 
   Dec-07-19 Karpov vs Spassky, 1971
 
Honza Cervenka: 17.Nh5 looks interesting.
 
   Dec-07-19 Uhlmann vs Karpov, 1971
 
Honza Cervenka: White could have played 31.Nxb5! as 31...Nxb5 loses for 32.Na6! Also 35.Nd3 Bg7 36.h4 gives white huge advantage.
 
   Dec-07-19 W Pietzsch vs Spassky, 1962
 
Honza Cervenka: 25.Bxe7 with next 26.Nf5 and 27.Rg1 would have been better.
 
   Dec-07-19 L Gutman vs Spassky, 1986
 
Honza Cervenka: Well, 24.c5 Bxd3 25.Qxd3 fxe4 26.Qa6+ Kb8 27.Qxa5 is dead lost for black.
 
   Dec-07-19 Vokac vs H Van der Veen, 1989
 
Honza Cervenka: 24.Qa3 was a little slip, which could have allowed black to consolidate his uncomfortable position caused by suboptimal choices in moves 20-22. 24.Qb7 or 24.Qb6 were objectively better options of white at the moment. But black completely missed tactical threat hidden in ...
 
   Dec-06-19 Karpov vs Balashov, 1971
 
Honza Cervenka: 18.Ng4 could have been better.
 
   Dec-06-19 Parma vs Karpov, 1971
 
Honza Cervenka: 48...Qf2 looks like a missed chance to win this game for Karpov, for example 49.a6 Qg3+ 50.Kh1 Nc5 51.Qxb4 Nxd3 52.Qd2 Nf2+ 53.Kg1 Nxh3+ 54.Kf1 Nf4 55.a7 h3 56.gxh3 Qxh3+ 57.Kg1 Qg4+ 58.Kf1 Qf3+ 59.Kg1 Ne2+ 60.Qxe2 Qxe2 61.a8=Q Qxc4 etc. On the other hand, he was quite lucky ...

  Honza Cervenka: <jinkinson: <Honza> W/regard to the problem you posted on June 6, 2016, there is no solution that lets white win is there?>

Well, there is a solution with a series of under-promotion:

1.h8=N g3 2.Ng6 fxg6 3.f7 g5 4.f8=N g4 5.Ne6 dxe6 6.d7 e5 7.d8=N e4 8.Nc6 bxc6 9.b7 c5 10.b8=N c4 11.Nc6 c3 12.Nb4#

  Honza Cervenka: Here is a solution: 1... e1=N 2.Rxe1 dxe1=N 3.Rxe1 fxe1=N 4.Nf3 d2 5.Nxe1 dxe1=N 6.Kb6 d3 7.Bxg3 d2 8.Bxe1 dxe1=N 9.a5 e2 10.a6 Nf3 11.Bxg2 e1=N 12.Bh3 Nd3 13.Bc8 Nc5 14.Bb7+ Nxb7 15.axb7#

Mar-13-18  zborris8: <White to move wins:> 1. g7 Yeah? No. I don't think this works. The Black king will somehow turn into a knight and escape.

  Honza Cervenka: <zborris8: <White to move wins:> 1. g7 Yeah?> The first move is correct. Of course, 1....Qxg7 is forced reply. And what now?:-)
Mar-15-18  zborris8: <And what now?:-)> The purpose of <1. g7> was for me to safeguard the bishop on h1 for the discovered check. <1...Qxg7 2. d6+>.
Mar-16-18  zborris8: Ok, I see it through now. It's not the king that turns into a knight, it's the pawn. Very good puzzle, <Honza Cervenka>!

  jith1207: And then there is the small matter of mating the king with a bishop and a knight.

Still better than these two against a queen.

Jan-30-19  JimNorCal: Mr Honza Cervenka, whose picture is your icon?
Is that you, or a well known chess player or ...?
Jan-30-19  JimNorCal: It's a classic look, simple yet elegant.

  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

  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.
Jun-16-19
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.

  Ron: Here's a suggested game for your Missed Chances collection. Zukertort's sacrifice was not sound; his opponent missed the one move that refutes it.
