  tamar: Very interesting <Calli> Lasker must have an unpleasant jolt to face 5 Nc3 in his later game against Alekhine if he knew about their friendship--Alekhine vs Lasker, 1914 -- a game which he survived and won only by some wizardry. The reality that the Exchange was very much discussed makes Lasker's decision to use it in the crucial game against Capablanca more understandable. He wanted to make him uncomfortable as he had been against Alekhine, only on his own turf, the 5 d4 variation.
Apr-05-04  ArchBishop: <chessfected> I had the same expression for that horrendous move (24.) Or was that move more or less forced? I can't see that.

  tamar: Quote from Garry on this game: "Dry, tedious play sickened Janowski--back in the match with Lasker (Paris 1909), he played the Exchange Variation very badly, and this had obviously been taken into account by Capablanca." He makes similar hastening the end blunders in that match, as in this shellacking... Lasker vs Janowski, 1909
Aug-27-04  Whitehat1963: Capa plays the opening of the day.
Jan-26-06  karlth: Romanovskij said that black was lost after 11. Rb1.

"Capablanca understood the position completely after 9. ... 0-0-0 and the rest was essentially just calculations and variations."

"Capablanca's understanding of chess was complete. He sometimes blundered and made errors when calculating but his understanding was perfect."

May-14-07  micartouse: It's interesting that Capablanca let Black get rid of his Queenside weaknesses in order to attack. I guess he saw 0-0-0 combined with the pawns on a6 and c6 and felt he could just pop a pawn up there to b5 and pry it open.

11. Rb1! saves time. He can advance a4 and b4 in a single thrust.

Apr-19-09  adrk: this a scheme of attack in all similar positions!!

What a lesson!!!

  DrGridlock: There has been discussion on the merits of Black's 24'th move ... Nf4. This move is clearly not Black's best, but Black is also lost by this stage. Komodo sees c5 coming in all lines (as <Calli> notes).

The question then becomes by which move Black's game became lost. Kododo also agrees with <Lawrence> and Junior that Black is in pretty deep trouble at move 21, and that ... Kd8 offers no better hope to Black than the game continuation of ... Kb7, and in fact Komodo rates it much worse.

Opening knowledge of the Exchange variation have changed much since 1914, which makes contemporary commentary on opening more difficult. (Who plays black and exchanges his bishops on e3 and f3 anymore)?

Komodo sees an advantage for Black at move 9, and sees o-o-o as very playable.

  DrGridlock: Black's move which no one has yet criticized in the discussion is 14 ... b6.

Komodo sees 14 ... Nd6 as very playable for Black:

Another move that has gone uncritiqued is Black's 21 ... Rd7. Komodo sees Black's game as still savable at this point after Rhe8, but Black loses half an evaluation point after Rd7:

In summary, 21 ... Kb7, 24 ... Nf4 and 9 o-o-o are not the losing moves for Black. Focus instead on 14 ... b6 and 20 ... Rd7.

Jan-08-12  King Death: The modern master learns from the old one in this game: Mecking vs Korchnoi, 1974.

  DrGridlock: <King Death>
Romanovski's proposition, quoted by others on the board here, that after 9 Rb1 White's game is positionally won, has been powerful.

Your link quotes Gabriel Velasco's restatement of this proposition, "At this juncture, Mecking came up with a surprising and effective plan, involving a queenside pawn advance supported by an odd rook maneuver."

Modern engine analysis suggests that the proposition is, however, quite wrong.

  DrGridlock: In "Modern Chess Strategy" John Watson writes:

"There is a great danger here for the student. He or she will pick up a book of annotated games by some world-class player and assume from such general descriptions that "this is the way the great way players think." In reality, most players are unconcerned with giving exact descriptions of their thought-processes; it is much easier to characterize a position generally, with hindsight, and ignore the gory details."

It's easy to pick a game like this one, and "reverse-engineer" commentary to suggest that if a game is won by a positional grandmaster, then every idea in it must be positionally correct.

The "gory details" are provided by Komodo, and suggest that at Black's move 11 after ... Rfh8, ... f5, or ... g5 it's Black's attack on the kingside that is in danger of breaking through before White can get b4 and a4 to break through on the queenside.

Jan-08-12  King Death: <DrGridlock> If you noticed I didn't cite that and don't buy into the proposition that the game is "won" at move 9. My opinion without the benefit of engine analysis is that objectively, White had no more than a small edge but psychologically he got the kind of game that was uncomfortable for Janowski to play.

This is where I think computers are useful in getting away from these categorical statements of the old days. They help provide objective analysis and understanding of things as long as the user has some understanding and doesn't just throw out a bunch of numbers. If I want that I'll pull an accounting book off the shelf and read myself to sleep.

If White had an edge from the opening, it was certainly a psychological one (getting to a position which Capablanca thought he could handle better than Janowski), rather than a positional one ("rest was essentially calculations and variations").

I agree that throwing out numbers can be a meaningless or confusing exercise. In this case, the numbers help us to change our understanding of the game.

  Boomie: <DrGridlock>

Although it is true that engine evals can help us understand a position, they are meaningless without noting the depth. For all we know, your evals were for depth = 12. This is way too shallow for opening analysis. In fact, engines are not very helpful in the openings as the ideas in the position are usually well beyond the horizen. Use opening books to analyze openings.

Jan-09-12
Premium Chessgames Member
  DrGridlock: <Boomie>

I agree that depth of evaluation is important. I generally went to 20 moves (or more) in the analyses I posted. Not deep enough to be exhaustive, but deep enough to convince me that the idea that White's game is positionally won at move 11 is questionable.

Opening books can be useful, but also have their limitations. In many instances, they rely on the "general descriptions" that we wish to analyze or verify. In other instances, there are lines which are no longer analyzed or played.

As an example of the exchange variation used in this game, there are 2,800 games with the exchange variation in the database. Of these 2,800, 420 contain White's response 5 Nc3. Of these 420, only to contain Black's reply Bc5. Winnow down to 6 d3, Bg4, and you're down to 8 games. 7 Be3, and you're down to 3 games: none of which have been played since Capablanca/Jankowski in 1914. People simply don't play openings this way any more.

One way to double-check engine opening results is to look at the strategies behind the lines they propose. For black, there are two keys: Nd6 as a defensive resource to provide control of b5, and a king-side pawn storm to counter-act White's queen-side pawn storm. Both of these intuitively make sense to me as insights into black's resources in the position.

Which opening book are you going to use to analyze the position after White's 11 Rb1?

Jan-09-12
Premium Chessgames Member
  Boomie: <DrGridlock>

Using the OE sheds some light on this opening.

Notice that 5...Bc5 is unusual and has had poor results. Opening Explorer

Also 6...Bg4 is rare and has had miserable results. Opening Explorer

So by move 7 the position is already good for white. GMs today would probably never reach this position. Anything that happens after is purely academic.

Jan-10-12  petamin: Can anybody explain me Why is good the exchange in 9...;BxKf3?
Jan-10-12  Retireborn: <petamin> Assuming you mean 13...Bxf3, Black wants to play ...Ng5-e6 to move his knight to a better square where it helps to defend his king. However 13...Ng5 would allow 14.Nxg5 smashing Black's pawns, hence 13...Bxf3 first.

It is not easy to suggest a better move, as White already has a ready made attack with b5. In the event Janowski decided to play ...b6 and ...a5 before ...Ng5-e6 which only made his position worse.

Jan-10-12
Premium Chessgames Member
  DrGridlock: <Boomie>

Opening Explorer can be a useful tool, however in this case it has significant limitations. Of the 8 games in the database, only 2 have been played since 1916 (only 1 since 1955), and most are between players of unequal strength (Chigoran v Schiffers, Lasker v Tarrasch, Lasker v Gittins, Capablanca v Jankowski, and Mastrovasilis (2580) v Stevens (2020)).

In a small sample size (8 games), with unequal competitors and few modern games, do you interpert the 7-1 for white victory score as resulting from an opening positional advantage, or from White outplaying black in the middle and end games?

To sharpen the discussion, do you believe, with Romanovski (and others), that at move 9 White's game is positionally won, and that only "calculations and variations" are necessary to complete White's victory?

Jan-10-12
Premium Chessgames Member
  DrGridlock: <retireborn>

Looking at the engine analyses of the position, black has 2 key resources in the position: (i) moving his knight to d6 to control b5, and (ii) launching his own pawn-storm on the kingside.

The advantage to black in exchanging on f3 on move 13 is NOT to relocate his night to e6 (it's headed instead to d6), but to draw white's rook to f3 so that black can gain a tempo by attacking the rook when black pushes his own pawn to g4.

  Boomie: <DrGridlock>

<Of the 8 games in the database, only 2 have been played since 1916>

This suggests to me that the line was abandoned because it doesn't work.

<do you believe, with Romanovski (and others), that at move 9 White's game is positionally won>

I don't know if it's winning but white does have the advantage. All timers like Capa, Alekhine, and Lasker looked into it and apparently didn't find anything for black.

Jan-10-12  Penguincw: 27.c6+ and the end is near.

Thank you.

It takes the queen out the pin from the Bg4 and out of the pin of the d-file, it protects e3 and it takes an eye on b4.
