Member since Sep-04-02 · Last seen Mar-17-18
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: 43.c4 with idea 44.c5+ Kxc5 45.Rc1+ and 46.Rc8 looks like a quite simple and straightforward win for white. It really hurts to miss that in such an important game.

Honza Cervenka: <Patriot: Material is even. White is in check and both pawns are one square shy of being queens. If white can avoid checks he will win. And he must avoid walking onto the a1-h8 diagonal or the a-file or h-file to prevent a1=Q+. The only way to win seems to be to use the ...

Honza Cervenka: Fine technique in Rook ending demonstrated by Tarrasch. Black should have inserted 15...dxe4 before playing Ng6.

Honza Cervenka: 27...Ra8?! (27....Qc7 was possible) and 28...Ne7?? (28...Qf8 was necessary) were mistakes leading to instant collapse of black who after 29.Nc4 just loses a piece.

  Domdaniel: Hej, Honza/Jan ...

I'm asking your advice, because you're a fine analyst, a good OTB player, an experienced CC player, and - after all these years on CG - a friend.

I'm still playing FIDE-rated team tournaments in Ireland, although my rating has gradually dropped from 2000+ to 1800 or so. I play in some weekend tournaments also, but I am no longer confident of getting my rating back up to where I feel it belongs.

So, I am thinking of mostly giving up OTB chess, and taking up Correspondendence Chess. What do you think?

Is this still a viable option, in the age of engines? I played some CC as a junior in the 1970s, and did quite well - but that was before strong engines. A couple of players who had similar OTB ratings to mine in those days have since become CC Masters. Plus I have been involved in some of the CG team games, such as those vs Arno Nickel.

Do you play CC at a competitive level? I think I could do reasonably well ... but I'm not sure about the apparent level of engine use (cheating?).

Have you any advice for me?

Thanks, Dom/G.

Missed chance by your countryman :(
Navara vs A Giri, 2016

  Honza Cervenka: <Domdaniel> I played my last serious CC game back in 2002. It was too much time consuming and also quite expensive activity then for me. Of course, since then the CC changed a lot with arrival of really strong engines and now it is more centaur than correspondence chess. I don't have problem with that, and I believe that one day I will return to CC played by e-mail but right now I am too much busy for doing that seriously. But I am playing for fun some online chess, and I still try to play OTB in team competitions to help my friends from my chess club (though with quite mixed results and very bad start of the current season).

  sachistu: Hi <Honza Cervenka>! I was wondering if you might have time to look at the introductory comments to a game in the publication Ceské listy sachové (1897)? There is an online copy available on (on the library tab) 1897 v2 page 95-96.

The typical venue, year and player information is apparently hidden in the introduction. From the limited portion I have been able to translate, there is apparently a discussion of the war of 1469 between King George (Jiri) of Podebrady and King Matthias (Matyas) of Bohemia. Exactly what, if anything, it has to do with the game escapes me. It was apparently a consultation game and the names of the players mentioned seem to be of that contemporary era (188n-189n).

I'm hoping you can translate enough of the text to determine the venue, the year and players (or cities) for both sides involved. I noticed from one of your kibitz you did not have access to online archives. If you are not able to access the chessarch site, perhaps I can extract the pages to send you. Thanks in advance for any help you can provide.

  sachistu: Hi <jan>. Have been away since June 2nd and just returned. The online (chessarch) copy is embedded in 3 volumes (1896 1897 1898) and thus not so easy to find. I will have to work on a way to pull out that section as the PDF (60Mb) is too big to send via my mail server. As soon as I can create something workable, I will send it to you.

  Honza Cervenka: <sachistu> The game was a composition of Dr. Jan Dobrusky and it was an allegory of the defeat and surrender of Matthias Corvinus by George of Poděbrady at Vilémov in February 1469 during so-called Bohemian War 1468-1478. The game was performed live by members of Czech Sokol and Czech Chess Association in historical costumes during a national exhibition.

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

  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.
Premium Chessgames Member
  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?:-)
Premium Chessgames Member
  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+>.
Premium Chessgames Member
  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>!
