|Jan-20-10|| ||visayanbraindoctor: <Everett: <theagenbiteofinwit> What you and Dvoretsky say of Botvinnik may be true, but remember that he is the first GM to use the exchange sac as a weapon in all sorts of situations. Petrosian was the most prolific follower, and brilliant extender, of this idea.>|
It was Janowski who first did this regularly way back in the 19th century; who first incorporated the positional exchange sac into his arsenal. The Janowski exchange sacs were true long-term sacrifices; wherein he had to properly evaluate the ensuing practical value of his minor piece as compared to the rook of his opponent.
See < Karpova's> excellent game collection Game Collection: David Janowsky's exchange sacrifices
Janowski was pretty successful with it too, even against World Champions and top players.
Janowski exchange sac vs:
Steinitz +1 +0 -0
Steinitz vs Janowski, 1898
Lasker +2 +0 -0
Janowski vs Lasker, 1896
Lasker vs Janowski, 1909
Alekhine +1 +0 -0
Janowski vs Alekhine, 1914
Pillsbury +1 +0 -0
Pillsbury vs Janowski, 1904
Marshall +1 +0 -0
Marshall vs Janowski, 1900
Blanking out Lasker, Alekhine, Steinitz, Pillsbury, and Marshall in games were he did the exchange sac is a totally impressive feat by Janowski! It would mean that he had an accurate sense of the value of a minor piece as compared to a rook; and the courage to actually do the sac.
Janowski's only 'failures':
Capablanca +0 +0 -2
Capablanca vs Janowski, 1913
Capablanca vs Janowski, 1916
Yet if one takes a good look at the above two games, Janowski's exchange sac did not really fail. In order to win, Capablanca also did the same thing later on in the game - he 'imitated' Janowski by making his own exchange sac in both games! Thus, it is quite evident that Janowski's sac had adequate compensation; which Capa neutralized by making his own sac. So even these 'failures' are in a sense successes for the positional exchange sac.
At any rate, it is not only Botvinnik or Petrosian or Kasparov who knew about the exchange sac. The pre-WW1 and pre-WW2 top masters were quite aware of it. The studious Botvinnik in fact may even have studied all the above games in close detail, especially the games of Lasker, Capablanca, and Alekhine who were his competitors. Botvinnik was known to thoroughly study all the games of his close competitors.
The above games also show just how well developed positional chess was by the turn of the last century. If some of these games were given in the internet as they are, without the names of the masters involved, even kibitzers with a heavy dose of present-day generation narcissism would probably be wowing them out. <What exchange sacs; this type of game brings chess to a higher level!... Oops! So it was more than a hundred years ago. Well these games may not have been that great after all, as we all know these doddering ancients had such amateurish competitors and had no computers to help them out. (",)>
|Jan-30-10|| ||KingG: No doubt I'll be accused of trolling again, but I find it laughable to compare those Janowski exchange sacrifices to those of the later Soviet players. They almost all either forced, obvious, give sufficient material compensation, or are made for an attack.|
Is anyone seriously going to compare them to the exchange sacrifices of Petrosian for example? I'm not going to even both giving examples, as they are so well known, but there are plenty of games collections out there for those who are interested.
If you want a good example of a modern exchange sac during that era, try the famous A Selezniev vs Alekhine, 1921, even though Alekhine immediately went wrong after the sac. I don't know too many other examples though.
|Jan-30-10|| ||ughaibu: The claim that Janowski had a 100% record, against Lasker, with exchange sacrifices, is outrageous: |
Janowski vs Lasker, 1909
Janowski vs Lasker, 1909
Lasker vs Janowski, 1909
Janowski vs Lasker, 1909
Janowski vs Lasker, 1910
Lasker vs Janowski, 1910
Janowski vs Lasker, 1924
|Jan-30-10|| ||Olavi: ughaibu, in all those games Janowski lost or blundered the exchange.|
|Jan-30-10|| ||ughaibu: And in the games given above?|
|Jan-30-10|| ||KingG: <And in the games given above?> Lol.|
|Jan-30-10|| ||keypusher: <Janowski's exchange sacrifices> I spent quite a bit of time on the 1896 example given against Lasker, as you can see from the game page itself. |
Obviously the sacrifice is made to break up Black's kingside; it bears no resemblance to Botvinnik's or Petrosian's sacrifices. Also (although the annotators in 1909 loved it) it's unsound.
Here's another example; I leave it to those who can determine such things whether Janowski sacrificed the exchange or was forced to give it up. Anyway, he got a lost game, though eventually he managed to draw.
Janowski vs Lasker, 1899
|Jan-30-10|| ||keypusher: Pace the list, here's another exchange sacrifice against Pillsbury where Janowski doesn't win, though he should have.|
Janowski vs Pillsbury, 1896
|Jan-30-10|| ||keypusher: <Also (although the annotators in 1909 loved it) it's unsound.>|
Ugh, I meant the annotators in 1896, of course.
Fans of the ancients looking for antecedents to Botvinnik's and Petrosian's exchange sacrifices need to go back before Janowski -- way back.
Saint Amant vs Staunton, 1843
|Jan-30-10|| ||KingG: <keypusher> Yeah, I was thinking about that game earlier, but I think the similarity with Petrosian's or Botvinnik's is more superficial than real. Usually they sacrificed the exchange to gain control of square, a colour complex, a pawn roller, or some other positional advantage. Staunton's looks more like a sacrifice to open lines towards the opponents's king. Having said that, it is a lot closer to their sacrifices than Janowski's are.|
|Jan-30-10|| ||keypusher: <KingG> I suppose you are right. Here is a sort of similar sacrifice from Pillsbury, but using a queen instead of a rook. :-) |
Janowski vs Pillsbury, 1895
Also, not to pound on the list too much, but here's a Janowski exchange sacrifice in a loss to Pillsbury.
Pillsbury vs Janowski, 1899
|Jan-30-10|| ||keypusher: Last one for now: beautiful exchange sacrifice by Janowski in this one, but Pillsbury doesn't take it. Lots of grand battles between those two.|
Janowski vs Pillsbury, 1899
|Jun-07-10|| ||Thrajin: Happy would-be birthday, Mr. Janowski. Perhaps I'll bake a cake topped with 142 bishops in your honor.|
|Sep-02-10|| ||GrahamClayton: Here is an interesting position from the game Janowski-Lester Keene, Manhattan Chess Club, New York, 1919:|

Janowski offered a draw but Keene declined, thinking he had every chance to win. Imagine his consternation when in the diagrammed position Janowski announced mate in 5 moves. Can you find the checkmate?
|Sep-14-10|| ||Eduardo Leon: <1.♘g4+ ♔h1 2.♔f1>|
With the idea that black will eventually have to play ...h2, allowing ♘f2#.
Forcing black to trap himself with 3...h2 right now. Another possibility is 3.♔e1 f2+ (3...h2 4.♔f1 transposes to the main line) 4.♔f1! h2 5.♘xf2#.
<3...h2 4.♔f1 f2 5.♘xf2#>
|Oct-10-10|| ||whiteshark: <I detest the endgame. A well-played game should be practically decided in the middlegame>, said David Janowski. |
Not my motto, though....
|Nov-02-10|| ||bengalcat47: I just recently bought the book David Janowski -- Artist of the Chess Board.
It features 64 games and shows Janowski at his finest against many of his contemporaries, including Lasker, Pillsbury, Tarrasch, Schlechter, and Capablanca, to name just a few.|
|Jun-07-11|| ||talisman: happy birthday David.|
|Feb-21-12|| ||Marcelo Bruno: <Thrajin> This remembers one of the positions present in Jaenisch's book "Découvertes avec le Cavalier aux échecs".|
|Jun-07-13|| ||SteinitzLives: A gambler, a dandy, not well educated, a good sized ego, but unlike so many chess players with these same traits, he had talent! No, not world class, but clever enough to get sponsorship for matches against Lasker despite not being in the champions' class. |
Janowski made the most of his talent (for chess only), and then regularly threw away tournament winnings money on the roulette wheel, which was known even then to be dramatically in the houses' favor compared to other games.
It would be interesting to see if Tal ever wrote anything about him.
Though of clearly different talent levels, they both loved to attack and they both loved to party. I like to picture the two of them playing speed chess. With Tal raising the stakes while lowering the time control, and Janowski, offering to go closer to the edge by dropping two minutes in return for an extra bishop!
|Jun-07-13|| ||brankat: He did have some interesting encounters with W.Steinitz, also with Burn, Chigorin... |
R.I.P. master Janowski.
|Nov-13-13|| ||Karpova: After 8 years absence, Paris became Janowski's residence again in 1924.|
From page 349 of the December 1924 'Neue Wiener Schachzeitung'
|Mar-09-14|| ||Karpova: Dr. Emanuel Lasker, Berlin, January 9:
<Janowski ist trotz seines Mißgeschickes in Turnieren und Matchen ungebrochenen Mutes. Und man muß ihm zugestehen, daß sein Stil weit besser ist als das geringe Maß seines Erfolges vermuten läßt. Der französische Kämpe spürt Feinheiten heraus, mit denen er geringe Vorteile meisterlich zu erreichen weiß. Nur scheint ihm die Fähigkeit der Konsequenz in etwas zu mangeln. Vielleicht erschrickt er zu sehr vor der Verwicklung. Zum mindesten vermeidet er es gar zu ängstlich, sich Blößen zu geben. Dadurch aber verliert sein Angriff naturgemäß die Wucht. Hin und wieder jeder jedoch führt seine Strategie zum Siege, und dann ist der ästhetische Eindruck stark.>
(Janowski is despite his misfortunes in tournaments and matches of unbroken courage. And one has to concede to him that his style is much better than the little success gives reason to believe. The French competitor senses finesses, with which he knows to reach small advantages masterfully. But he seems to lack the ability of being consequent in something (another possibility is: But he seems to somewhat lack the ability of being consequent). Perhaps he is too frightened by complications. At least, he tries too anxiously to avoid lowering his guard. But thereby his attack naturally loses its impact. Every now and then, his strategy leads to success and then the aesthetic impression is strong.)
