  Phony Benoni: Odd how the c6 pawn, the focus of the "minority attack", wound up surviving to the end.
Nov-17-10  Shams: Hmm, actually 1.Nd5 Qxd5 2.Bxf6 Qc5+ doesn't lead anywhere. I'll keep looking.
Nov-17-10  frogbert: yup. there was no good answer. opsahl tried taking the knight with the queen (Qxd5) but didn't get enough because the bishop on d7 hangs if he takes the rook after 18. Nd5 (threatening Nxf6+) Qxd5 19. Qg4+ Kh8 20. Bxf6+ Bxf6 21. Rxd5

here he tried Rg8 but I can return an exchange with Rg5 too, so he resigned 6 moves later, after my 28th move.

Nov-17-10  frogbert: shams, you forgot an important check, forcing the king to another unfortunate square. sorry for spoiling it, thought you'd seen it all when i posted the line. didn't see your second post.

i was rated around 1500 when i played this game, btw.

Nov-17-10  Shams: Dammit, shams, combine your ideas. Nice stuff <frog>. Way to beat on the geriatrics. :)
Nov-17-10  Shams: <i was rated around 1500 when i played this game, btw.>

So you're saying I should give up chess?

Nov-17-10  frogbert: hehe. well, my rating kept going up - and norwegian ratings under 2000 are known for being way "too low" compared to say fide or uscf ratings - i.e. a norwegian 1500-player is typically 17-1800 fide, a 1700-player often around 1900, and 18-1900-players in norway typically around 1950-2050 fide (or higher). [i'm only just above 1900 in norway and almost 2050 fide, for example.]

only at around 2250 does fide-ratings and norwegian ratings seem to become approximately comparable. i've seen that people with fide-ratings typically get another 100 points added to their "ratings" if they want to participate in uscf rating category tournaments.

Nov-17-10  frogbert: <Way to beat on the geriatrics.>

opsahl appeared to be a very kind, nice man when i played him on his older days. the only trouble i had was during the post-mortem, when i felt that i was disturbing those in the room next door (still playing) the few times i spoke loud enough for opsahl to hear what i was actually saying. ["you must speak louder, i don't hear very well, young man."]

but you're right: i should show more respect towards the elderly.

  perfidious: <ljfyffe> The good Mr Muir obviously had not met me yet, for we only played at the very end of his storied career. (wink)

It was a pleasure to play Walter and would have been still more enjoyable had we met at the height of his powers.

Oct-23-14  ljfyffe: Obviously!
Jan-25-17  Howard: A perennial problem with Chernev's books was his failure to explain just where the loser went wrong in a given game, and this one's no exception.

As I recall, one mistake Black made was not keeping his rook on his 7th rank around the 38th move. If he had, then the f-pawn would have been pinned, and this would have given Black's king more wriggle room several moves later.

Jan-25-17  Retireborn: In the first instance Black should certainly keep the queens on with 28...Qg6 (instead of 28...Qxf4) and then aim for some K-side counterplay with moves like ...Re4, ...h4, and (if allowed) ...Nf5.

Oct-02-21  Gaito: The so-called "minority attack" is only one of two or three good plans at White's disposal in order to combat the Carlsbad pawn structure.

Maybe some of the kibitzers would please enlighten me as to why it is called "Carlsbad pawn structure". Of course, I suppose it was first played during a tournament in the German town of Carlsbad, but when and by whom? There was a very famous tournament in Carlsbad in 1911, I think it was Richard Teichmann who won first prize. But was this pawn structure originated during that tournament? There was another famous tournament in Carslbad in 1929, where Nimzovich won first prize ahead of Capablanca and Rubinstein. In fact there were many tournamets in Carlsbad, another one was in 1923, won jointly by Alekhine, Bogoljubov and Maroczy. I would like to know exactly in which of those tournaments the Carlsbad pawn structure took its name and what was the source game.

Oct-02-21  Gaito: The following game between Efim Geller and I. A. Horowitz is just another fine example of White's minority attack against the Carslbad pawn structure:

Geller vs I A Horowitz, 1954

Oct-02-21  Gaito: Capablanca also played some fine games with the theme of the minority attack against the Carlsbad pawn structure. The following game is perhaps his most famous example: Capablanca vs Golombek, 1939

The Carlsbad Pawn Structure (QGD Exhange, Caro-Kann Exchange, Scandinavian, etc.) term was popularized from the 1923 Carlsbad tournament, but the structure was around long before that: Karlsbad (1923)

Here's a bit of strategy:

Games to look-up: https://www.csee.umbc.edu/~sherman/...

The Sicilian Wing Gambit, Carlsbad Variation was around long before 1923, but I do not recall it's exact origins.

1. e4 c5 2. b4 cxb4 3. a3 bxa3

Thanks for the link, but it must be mistaken. Yesterday I was checking all of the games played at Carslbad 1923, and I could not see even a single game where the "Carlsbad pawn structure" occurred. Maybe I missed the stem game. Could you plsease tell me about one game played at Carlsbad, 1923 in which the Carlsbad pawn structure occurred? Maybe I overlooked it.

Oct-03-21  sudoplatov: I did find some earlier instances of the "Karlsbad Pawn Structure" K Walbrodt vs Janowski, 1898 Marshall vs Bogoljubov, 1924 The Pawn Structures also occurs in the Cambridge Springs Defense but with different tactics. Marshall vs Teichmann, 1904 Earlier (pre-WWI), the ideas of ...b6 (with pre-Tartakower ...Bb7 in mind) and ...dxc4 followed by ...Nd5 or ...Ne4 were more popular.
Oct-04-21  Granny O Doul: The site chess-world.com says "this variation (1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.cxd5 exd5 5.Bg5 c6 6.e3 ) became popular during the strong tournament which was held in Carlsbad in 1929". I gave up after not finding a single example among the first 100 games of the tourney, but maybe I'm just a quitter.
Oct-04-21  RookFile: 29.....Rg6+ was possible, to chase white's king into the corner. It might have helped.
