Subject: KEY-GAMES or Demonstrative :

There are certain Chess games that may overturn theory or show clear examples of the strategy and tactics of a given variation to the extent that they become Key. And by understanding these, one can synthesize continuations in associated lines. These are games that are critical to know, to really be proficient in a given opening. And often positions from them will be repeated many times, with various attempts at improvement stemming from them. Or perhaps the play from them is so decisive that one side of the position is then deemed too risky to play. Or found to be unsound. Or there is at least one major idea from them that is crucial to theory.
Besides those games, I would also like this thread to contain games that are demonstrative of some technique, be it an endgame finish, an attack (sacrificial or not), successful defensive technique, opening play or any other demonstration that a player would find essential or useful to know.
I would like to invite everyone to show such games, be they personal or by GM, or other games. Also to comment upon any submitted by myself or by others. And even to offer annotation to any game(s) appearing here. Whether you or someone else has submitted them. I would like the purpose of the thread to be increasing understanding of the game of Chess in any way, and at/for different levels of players as well. Also, please do indicate any question(s) you may have about any of the games and are unable to figure out for yourself. And I hope everyone will jump in and answer the questions that do arise. That will be one of the most interesting parts of this exercise, to me; To see what it is that players of various strengths aor styles would ask about. And the variety of thoughts that come about in reply.
Regards, Craig A.C. }8-)
PS// Most of my own Key Game familiarity will be with games played prior to about 1992, at which time I pretty much discontinued any intensive Chess studies. I hope there is a lot of new ideas out there that I haven't seen ! But with such good and inventive players I have never gotten to study, such as Anand, Kramnick, Adams, Carlson, etc ... I am sure there will be some Very Interesting games out there. [EG...When I was in my Postal and OTB heyday, NO one Ever played a serious game using the so called "English Attack" line featuring f3 and so on vs the
Sicilian. It was considered dull and unenterprising, if not inadequate.] There are even many games from the Polgar sisters that must be very excellent to know, but I dont. The examples from them that I do know, are usually very creative and enterprizing.
But dont limit yourself to newer games if you feel there is value in an old or classic game. Sometimes those are the best. Yet nary show up in our tournament experience if players now believe that game was the last word on a certain line of play. But still it is quite worthwhile to know of and understand WHY that is so, imo.
So dont be afraid to post one that may now be superceded in importance, but was Key in its day. Or continues to hold instructive value. We Need To Know !
And I would like to see some new forum contributors come forth here, and some of you who havent been around for awhile. We need your help now. Please? :)
Please help me to make this a very interesting and informative thread, with your games, questions, and answers ... which we will all work together to decipher. !

Karpov - Korchnoi 1974 Dragon Sicilian

In my view, this is probably the most important game in the Yugoslav Variation of the Dragon Siclian, that has ever been played. And one that is absolutely critical to know of if you plan to engage in either side of that opening. It is also an Excellent example of an h-file attack vs Black's fianchettoed 0-0 king position.

Here is the game

from a different database. A point of interest. The attack now known as the Yugoslav was formerly known as the Rauser Attack in the 1970's. I'm not sure when the name change took place. And often a name may be changed in one country at a time, or by one particularly important publication of it that starts the Chess community using a new moniker for it. I would be interested to know, if anyone could tell me if it was such an article causing a fast change? Or a more gradual process as in the former methodology?

Velimirovic vs Bukal

This is not the game from Velim that I was actually searching for. I'm not sure if it is Key ... but the Kingside assault is just too pretty to pass up. So I'm bringing it here and hope you will enjoy it too.
Velimirovic was one of the most exciting players of his day, playing much in the 60's and 70's, in very sharp style reminiscent of Tal / Bronstein. And as you might have guessed, was one of my very favorite players to follow. If you want to put some excitement into your play or just your day, you MUST see Velimirovic. Any tactical player Must fall in love with him, or be losing their eyesight!
If you have not seen his play before, Please let me know what you think. Even if it is just to say "That dogs not so shaggy" :))

Yugoslav attack...

...I think it was formerly known as the Porcupine Attack. I knew it as the Yugoslav attack int the early 1970s... In a GK game last year, I followed the Karpov-Korchnoi game to which you allude, with a rather interesting, if disappointing, result. I can't say my handling of the early endgame was particularly joyful...

Black: feyenoord (obviously a football fan)

ionadowman ...

Yes, your opponent was following later theory I believe (tho its hard to know. Sometimes a key game causes play to revert to earlier ideas). With Re8. In any case it's been seen many times in play since this one. Often back in the early 80's USA otb was where I've met it. (Ragnvald Nilssen played it a lot.) And obviously is better than following Korchnoi unto doom above. And the sac at g4 was being seen in postal play before I played 8th USCCC back in the later 80's.
There was a major mono-gram published in Chess Life and Review in 1975 (possibly 76 but I doubt that) about this Karpov-Korchnoi (there was also a Karpov-Korchnoi Dragon prior to this that was a key game before it). Possibly it was Sv. Gligorics "Game of the Month". I'll try to verify. Anyway it discusses many possiblities arising from this game. One was retreating Qd8 after the Rooks both go to BL's c-file. Which was considered inadequate. From memory thin the refutation involved WT timely Nd5 vs the Nf6.
Anyway dont feel bad. We are in the same boat. Dare I say Ship? I took a loss as WT too, in postal against WmJShipley while trying to follow Sherzer analysis as WT using Bg5 vs the ....h5 line that they have come to call Soltis (Tho way back the Soltis line was the one where bl played Nxd4 then ....b5. So should they say New Soltis and Old Soltis, or call one the Andy? ? anyway...) Tho I did a hypnotic blunder later in the game it appeared before that that Shipley had improved the thing to where the question ... should WT just call it a bust arose to me.
I'm hoping this game will show up when I recover my XT games, if 8th USCCC is there. Unfortunately I think it is in the 80% of my games and theory destroyed in the flood. (No not THAT flood ... a few years after that one :)
[My 3 Dragons as BL in USCCC play thus broke even with that game. A win vs a 2300+ and draw vs 2200+]

Thanks for your reply, Craig!

...I wasn't too unhappy with the game - I was happy with salvaging the draw, even though it put a term on my winning streak! I was aware that we were following a later game than K-K '74, but don't recall at what point we struck out into "terror" incognita - it was a few moves after 18...Nxg4 at any rate. Still, I haven't trusted Markland's evaluation of 16.Nde2 since then. It seemed to me Black has a marginal edge after 18...Nxg4, and I haven't found any improvement for White.

Edwards - Curry / Caro-Kann

This is a Caro-Kann game from APCT between Jon Edwards(2400ish) and Bob Curry(2300ish) , in the variation ...Nf6, Nxf6 gxf6 which Curry has played very successfully to the point of developing a formula for the opening that included strategy of fighting for f5 and f4, when to play ...Nd5, etc. Not just moves but sequences and timing of them.
This line Wt plays Ne2 rather than the more common Nf3. And the white side was having some rather unfavorable results. Largely, I suspect due to the awkward nature of his attack upon the BL Q-side that leads with the a-pawn and often got locked up, rather than opening lines. Edwards finds and improvement however, in spite of that. Which is the point where I last recall seeing the game. So have not yet seen the end yet, myself. But note the outcome is as I expected. I'm trusting there wont be a major snafu involved. And look forward to seeing it in full shortly. But dont plan any notes for anything that does not ellicit interest; as there was not much for the Dragon. Nor Velimirovic.
The game may be viewed at GameColony . com by using the first link I put in above that says www chesslab . com here. Then type in Edwards and Curry as the players when you get there.
A hint about this site. Leave the rating indicator at ANY when expecting to look up CORR games, as they usually will not have any ratings used, unfortunately, on that site.
[Also a tip for the other site that I used in the second link which shows here as Chessgames . com . On it, do not check the boxes for KIBITZING or ANNOTATIONS at first or it often shows NO GAMES. First see if there are any games at all there. THEN look for ANNOTATIONS or KIBITZING and you may be more successful in seeing what is available there.]
