  sachistu: Another version of this game has Black playing 70...Kb4 (instead of ...Kb2). After the move given here e.g. 70...Kb2, White has another forceful line with 71.Nxd1+ and after say ...Kc2 72.h5! and if Black tries to advance the a-pawn ...a3, then 73.Nc3 forcing Black to lose a tempo, after which White will either queen first or win Black's new queen. My only point is that White does not have this option if Black played 70...Kb4.

Anyone have the tournament book or come across this game in a magazine?

May-01-17  Paarhufer: <sachistu> It would possibly save time, if you tell more about what you have and what you have done. For example, where is the other version from? And where have you been looking for?

Btw, are you sure a tb exists for this tourney? I doubt this.

  sachistu: <Paarhufer> The thought about the/a tournament book was more hopeful speculation than any awareness of existence. I also thought perhaps someone might have bulletins as that was a national master tourament.

Both versions came from online sources. The version with 70...Kb4 is in the 2016 Chessbase database. I've noticed they are starting to include (apparently) corrected versions of several games, but unfortunately, a lot of 'newer' Chessbase information is just the old scores with new commentary added. Regardless, I prefer to rely on the score from books, magazines or newspapers rather than online versions that typically cite no source.

I do not have Deutsche Schachblatter for 1933, but I do have Deutsche Schachzeitung for 1933. That's the only German magazine I have for 1933. I also have the Wiener Schachzeitung for 1933. The other 1933 magazines are Dutch, Yugoslav, Swedish, Russian, Hungarian, Czech and English. It might be in one of those, but lengthy games like that are not the norm. In any event, I'm in the middle of moving, so it's hard to get my hands on any of my material. You should hear the groans when I start opening boxes! No worries. When I get settled, I'll go through all of them to see if anything turns up.

May-02-17  Paarhufer: <sachistu> I see.

The local newspapers published each a few games, but not this one, if my lists are complete.

  sachistu: That's not too surprising. Thanks for looking <Paarhufer>. I knew it was probably a long-shot. If I stumble upon it, I'll let you know.
May-03-17  hemy: <sachistu> Alan McGowan is working for many years on his book about Kurt Richter. As far I know it is almost finished and may be published soon.

  sachistu: <Paarhufer> Alan McGowan was kind enough to send me a scan of page 26 from Ranneforth's Schachkalender for 1934. The position just after Black's 60th is given. From there, the score is continued with Richter's notes. Move 70 is ...Kb4. Richter also gives the note, if 71.Nxd1? a3. Clearly in the version given on the <CG> site, this is impossible as after 70...Kb2, 71.Nxd1 would be with check. This is enough to convince me 70...Kb4 was the move.

McGowan was also kind enough to send me Richter's score sheet for the game. Unfortunately, the score sheet is of less help as Richter had a number of errors (too numerous to mention) when recording his score sheet. However, virtually all were correctable, as Alan pointed out. The one critical error that probably lead to the score variances (versions) was Black's 70th, which was recorded as 70...Kb3, which is impossible given Black's capture on a4 with the Bishop on the next move. I suspect the reason for the erroneous version e.g. 70...Kb2 is that on move 74, Richter's score sheet shows 74...Kd2. Hence whoever transcribed the game (perhaps using his score sheet) assumed move 70 must have been 70...Kb2. However, Richter's score sheet clearly shows 72...Kc5, so it is apparent move 74 was ...Kd4 (as also given in the Ranneforth article).

I'll check over the score given here on <CG> for any other variance before submitting a correction slip. Thanks <hemy> for mentioning the McGowan link. He was very helpful in providing information about this game.

May-06-17  hemy: <sachistu> I'm in touch with Alan McGowan for many years. We are always helping each other. You can see the picture of him visiting me on January 2014 on the page 315 of the book "Jews in Lithuania chess history" (in Lithuanian language): https://www.dropbox.com/s/w76gkpozk... He is sitting on the right of me. There are also credits for his help.

On the picture bellow you can see Mikhail Tal's simultaneous exhibition in Vilnius on November 13, 1964. This picture is from my private collection and never was published before.
