Honza Cervenka
Member since Sep-04-02 · Last seen Sep-21-23
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.)

   Sep-18-23 S Nikolic vs R Byrne, 1967
Honza Cervenka: 31...a6?? 32.Kg2?? looks like a case of mutual chess blindness. After 32.Qa4 with double attack against Pa6 and Re8 black can just resign.
   Sep-18-23 A Tsvetkov vs Hort, 1964
Honza Cervenka: I am not sure that black's sac of Pawn for Bishop pair was correct but in the game it worked well.

Honza Cervenka: 13.e5 and 16.Ne2 were mistakes losing this game. 13.Rf1 and 16.Rd1 were better choices.

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.

  sachistu: Hello <Honza Cervenka>. Regarding my question from Dec 21st, I was re-examining the Trencanske Teplice 1949 tournament book. Near the rear (page 297) there is an Epilogue (Doslov) page. One of the items covered on the page is a key to the abbreviations used for the multiple annotators of the games in the book.

In some cases, the abbreviated names are in upper case i.e. LP for Ludevit Potucek, others in lower case i.e. lp for Ludek Pachman.

Among the names and abbreviations is -ar for Jaroslav Sajtar and JS for Jan Sefc. Now why the book (and Czech magazines) chose to use -ar, rather than -js is a bit of a mystery to me.

Jaroslav Sajtar was a well-known player and frequent annotator and/or editor, so while this may not be 100% conclusive, it's close enough for me to believe he was the mysterious -ar I often saw in magazines like Ceskoslovensky Sach and others.

Just wanted to let you need to research further. Sorry I failed to notice this earlier.

Premium Chessgames Member
  Honza Cervenka: <sachistu> So my first guess that "ar" can be Jaroslav Sajtar was correct after all.
Premium Chessgames Member
  sachistu: Yes <Honza Cervenka> your instincts were correct! I'm still puzzled why '-ar' would be used, but it's a moot point now since we know who it was.
Premium Chessgames Member
  Honza Cervenka: <sachistu> "-ar" are last two letters of Sajtar's surname and it was free for use then unlike "js" (used by Jan Sefc).

  MissScarlett: Are you there?
Aug-01-22  belgradegambit: Is there anyone with an older member since day than Honza?
Aug-02-22  stone free or die: <belgradegambit> that's an interesting question.

I thought I once had a list of some of the more significant early members of <CG>, but I just spent 5-10 minutes looking for it with no success.

I think I used Wayback to look at very early kibitzing history on <CG>, and culled out the names I recognized.

Easy to redo - but I won't be doing so just now.

We can agree though that <Honza> is one of the early's.

  Honza Cervenka: <belgradegambit: Is there anyone with an older member since day than Honza?>

I am here nearly 20 years since September 2002. There were many people here already then but many of them are inactive for a long time and some of them are unfortunately dead. And some of them like User: refutor occasionally pop up after long time just to say hello to old friends. But quite a lot of people are here since 2003 or 2004.

Premium Chessgames Member
  Benzol: Well I for one am glad that Honza was and is still here. How are you doing old friend ? 😊
Premium Chessgames Member
  Honza Cervenka: <Benzol> I am still alive, and that is quite satisfactory.

For solution see the first comment in J Cervenka vs J Kovar, 2010 (I missed that over the board).

  waddayaplay: Oh you are still here.

I was trying to remember all the power users from when I was active.

I wonder what happened to this site? When I was here it seemed to be getting bigger, with GMs joining, but now it's like it has been in decline for 5-10 years.

Premium Chessgames Member
  Honza Cervenka: <I wonder what happened to this site?> The main problem is that both co-founders of this site, Alberto A Artidiello and Daniel Freeman, unfortunatelly passed away in 2015 and 2018. But the site is still alive.
Premium Chessgames Member
  waddayaplay: Oh that sucks.

I always enjoyed being an active user.

It's weird when you leave a community and come back to a sort of ghost town.

  technical draw: <Is there anyone with an older member since day than Honza?>

I'll be here 20 years in November.

Hello, <Honza>. We used to chat in the early days but nowadays I just stick mainly to my forum. (Except when I want to bother <WannaBe>!)

  Bishoprick: I'm in Prague and or in Blatna at least once a year. I am probably much older than you, but it might be fun to get together. In the 70's I reached a USCF rating of 2026, but now I'm only around 1800, but still having fun with chess. My favorite players used to be Tarrasch, E.Lasker, and Rubenstein, and in more modern times, Fischer and Karpov. But I would say that young Carlsen is also fun to watch.

  Stonehenge: That's a very interesting puzzle.

Obviously not Kh3 but the other two options...

Stockfish knows the answer but I still don't understand it :(

Premium Chessgames Member
  Honza Cervenka: <Stonehenge> The problem with 1.Kh1(?) is, that it gives black sufficient defense after 1...Kf8! =. That was the move, which was actually played in a real game, and it led just to a draw. Fuller answer you can find at Hort vs O Kinnmark, 1961.
