More World Championship Qualifiers?

The question raised in Groningen 1946: A World Championship Qualifier?, reminded me of another exchange on a similar subject.

Thanks a million for the information on the World Champions. The thoroughness of your work reveals that it is a labor of love for you. For this reason I was surprised that you don't have the games from the 1927 New York and 1938 AVRO tournaments. Both of these tournaments were considered "Candidates Tournaments" in their day. You can get the games, as I'm sure you are aware, from

ftp://ftp.pitt.edu/group/student-activities/chess/PGN/Events/0-1991/

I used your 1948 FIDE World Championship Match table as a template to make the tables for the above-mentioned tournaments. If you want me to, I'll send them to you.

Thanks for your message. Sorry for the delay in responding. I wanted to double check the facts about the two events that you mention. Unfortunately, it appears that neither event was a candidate tournament when it was played.

New York 1927 was supposed to be a candidate tournament, but Alekhine had already challenged Capablanca. He threatened to drop out of the event unless the candidate clause was dropped, which it was.

Although Botvinnik started match negotiations with Alekhine at AVRO (Amsterdam) 1938, the event was won by Keres and Fine. When the discussions with Botvinnik stalled, there was some talk of an Alekhine - Keres match, because of Keres' first place on tiebreak. This talk ended when WWII broke out.

Anyway, I would be happy to have your tables. Perhaps I can work them in somehow as 'almost candidate tournaments'. - Best regards, Mark

I bow to your wisdom in these matters, but consider these points:

Keres, in his Complete Games (page 125 in my paperback edition) regarding the AVRO tournament states, "The winner would have the right to a match with Alekhine." Next, on page 128, "So I shared first and second prizes with Fine, but obtained the right to challenge the world-champion, Alekhine."

P. W. Sergeant, in his book Championship Chess gives a footnote regarding the New York 1927 Tournament: "It appears that it was vital for Alekhine to take at least second place in this tournament to establish his right to a match for the Championship; but I have not been able to trace when Capalanca laid down this condition, if he did so. It could not be considered as an unfriendly gesture, however, in view of Nimzovitch's claim."

I noticed that you have a few matches that are relevant to the Championship series, while not exactly a part of it, such as the exhibition match between Staunton and St. Amant, and the exhibition match between Lasker and Janowski. With this in mind I thought New York 1927, AVRO 1938, and though I forgot to mention it in my last note, Cambridge Springs 1904, where Marshall earned the right to challenge Lasker, would fit in well with the others. I'm sending you the crosstables for these tournaments, in case you decide to use them.

Now that I think of it, I made the NY27 and AVRO38 tables using your 1948 as a template, but the CS1904 table I copied from some place I found on the Internet.

Thanks for the files. I'll keep them in a safe place and hope to use them some day soon.

There is no question that the events you mention are an important part of the history of the World Championship. In fact, there is a story behind the negotiations for every match (and near-match) of the pre-FIDE era. Unfortunately, I have never taken the time to research them properly. I find they are fairly well documented in Winter's book on the 'World Chess Champions' and Kasparov's books on his 'Great Predecessors'.

Sergeant's 'It appears' comment is curious. Cafferty, who wrote the chapter on Alekhine in Winter's book, was certain that the Capablanca - Alekhine match had been agreed before the New York 1927 tournament started. A timeline of the most significant actions would be useful.

When I read the entire paragraph on p.125 of Keres' book, I understand that the candidates' event was an idea of Euwe in conjunction with FIDE. When Euwe lost the title to Alekhine, the candidates idea was lost with it. On p.198 of the same book Keres wrote, 'Before I left for Buenos Aires [Olympiad 1939], I had agreed in principle with Dr. Euwe to play him a friendly match. Although it was a question officially of a friendly match, the general opinion in the chess-world was that the winner would have the moral right of challenging the world champion, Alekhine. My prospects of bringing about such a match through the results of the AVRO tournament, had not proved realisable.'

If you would like to discuss this further, I would suggest the forum I manage...

Groningen 1946: A World Championship Qualifier?

I've occasionally wondered why Smsylov was invited to the World Championship tournament held in 1948. The other invitees had all made their reputations before World War II. Smyslov, born in 1921, started to achieve his results during the war.

I once asked the question on the Forum for About Chess (FIDE rule), and Glenn Giffen replied.

Probably more than anything his +2 win over Reshevsky on second board in the US-USSR telex match September 1945 would stick in people's minds. His other notable achievements were 3rd at USSR ch. 1940 ahead of Keres and Botvinnik, 1st at the Moscow ch. 1945 ahead of Ragozin and Lilienthal, 3rd behind Botvinnik and Keres at the Absolute ch. 1941 and 2nd after Botvinnik ahead of Boleslavsky at USSR ch. 1944. • Soon after the FIDE Congress at Winterthur 1946, Smyslov came 3rd after Botvinnik and Euwe at Groningen in August-September 1946 and then blanked Denker +2 in the US-USSR match in Moscow September 9-12, 1946.

Glenn knows his chess history better than most, and his reasoning was solid, so I left it at that. I was surprised to read the following in Kasparov's 'Predecessors II'.

An important landmark in Smyslov's career was his first international tournament -- Groningen 1946. From the results of the event FIDE determined the sixth participant in the forthcoming match tournament for the world championship (five had already been named: Euwe, Keres, Botvinnik, Reshevsky, and Fine). [...] In the end Smyslov finished third (behind Botvinnik and Euwe), thus securing a place in the match-tournament for the world championship planned by FIDE. (p.272-4)

There is a lot about the World Championship that I have yet to learn, but I thought I was beyond the stage of missing an entire qualifier. What do other sources say?

Susan Polgar's Commencement Address

Today is Video Friday on CFAA, and I have 10 minutes to prepare the post. Forgive me for re-using the link to Susan Polgar's commencement address at Texas Tech University -- Texas Tech' s New Queen of Chess -- which I already highlighted on About Chess.

Even Susan's detractors, many of whom are chess bloggers, will admit that her speech was an important moment for chess. Don't miss the link to the page bearing the same name as the video -- the full story.

One Bad Move Loses the Advantage, Two Bad Moves the Game

Once again on Smyslov's Sparklers, I'm starting to understand Why Did White Lose in Reshevsky - Smyslov 1945?. In the diagrammed position, Reshevsky played 28.Nd3. Kasparov gave the move a '?' and wrote:-

I don't understand why White didn't play 28.e4! (perhaps because of time trouble?). The opportunity is also not mentioned by the commentators, although 28...Nc3?! 29.bxc3 Bxc3 30.Rf1 Bxd4 (30...b2? 31.Rd7) 31.Bxd4 favors White. And if the Knight moves to another square, he also has no reason to complain -- on the contrary, he may be able to seize the initiative. Apparently Sammy thought that e3-e4 would not run away, and he decided to play more quietly, underestimating his opponent's clever reply.

I analyzed 28.e4 and agree completely with Kasparov. White keeps a small advantage with the move. Was 28.Nd3 the losing move?

[FEN "r1r3k1/1q3ppp/4p3/pB1nN3/Pb1R4/1p2PP2/1Pb1QBPP/R5K1 w - - 0 28"]

The game continued 28...e5 (a very classy move) 29.Nxe5 (29.Rc4 also looks interesting.) 29...Bc3 30.Nc4. Here Smyslov and Kasparov give the same line: 30.bxc3? Nxc3 31.Qd2 Nxb5 32.axb5 b2. The variation 30.Bc6 Rxc6 31.Rxd5 Bxb2 32.Rb5 Rb6 also looks bad for White.

There appears to be a little problem with the analysis of the two World Champions. After 30.bxc3 Nxc3, White has 31.Qf1, which is better than 31.Qd2. Now 31...b2 doesn't work as well because of 32.Re1 b1=Q 33.Rxb1 Bxb1 (33...Nxb1 34.Bc4) and then 34.Rd7 Rc7 35.Bc6. Here I looked at a lot of variations and White always comes out better, although Black can force a draw.

What am I missing? It appears Reshevsky made one bad move to throw away the advantage and a second bad move to lose. This is a pattern seen in many games at the highest level.

Sequences of Unexplained Moves

Continuing with Smyslov's Sparklers, I'm going to take another stab at Why Did White Lose in Reshevsky - Smyslov 1945?.

The diagrammed position looks complicated. Reshevsky played 20.dxc5, and the game continued 20...Nxc5 21.Nd4 Rdc8 22.f3 Nb3 23.Nxb3. Both Smyslov and Kasparov thought 21.Nd4 was a good move and gave it a '!'. Smyslov noted, 'White concentrates his minor pieces on c6, leaving his g-Pawn en prise. The sacrifice is a sham.' Kasparov copied the remark and the subsequent analysis verbatim. The other moves in the sequence went unremarked.

(After 19...Nf6-e4)
[FEN "r2r2k1/1q2bppp/1n2p3/pBpbN3/Pp1Pn3/4PN2/1P2QPPP/R2RB1K1 w - - 0 20"]

Call me blind, but I don't see that 20.dxc5 is forced and I don't see why White can't play e.g. 20.Rac1. Now 20...Bb3 is a blunder because of 21.Bc6. Black can play 20...f6, forcing the Knight to 21.Nc4, from where it came a few moves ago. In the meantime, Black has weakened the Kingside slightly and there is nothing particularly wrong with returning the Knight to c4. Note that White could also play 20.b3 instead of the text. The Pawn is immune.

The habit of leaving long sequences of moves unexplained is frequently annoying and sometimes misleading. Many top GMs do this routinely when annotating. If the variation is forced, let's understand why. If it's not forced, why is it preferable to the alternatives?

Pre-computer Postal Chess

The first time I looked through my old postal games using a computer, I found this. In the diagrammed position, Black, who has sacrificed a piece for an attack, played 22...Qh1+, and offered a draw that I accepted.

73Nf-15
Gregory, Vazgen

Weeks, Mark
(After 22.Kg2-f1)
[FEN "r3r1k1/1p3p1p/2pp2p1/p3b2P/2PN4/4BP2/PP1QNn1q/1R2RK2 b - - 0 22"]

The computer quickly finds a win for Black with 22...Nh1, when there is no defense to 23...Bf4. I remember that I accepted the draw thinking that I had nothing better than 23.Kxf2 Qh2+ 24.Kf1 Qh3+ with a perpetual. It looks, however, like there's still a fight: 23.Ng1 Nh3 24.Qg2 (also interesting is 24.hxg6 Bf4 25.gxf7+ Kxf7 26.Qg2 Qxg2+ 27.Kxg2 Bxe3 28.Rxe3 Rxe3 29.Nxh3) 24...Qxg2+ 25.Kxg2 Bxd4 26.Bxd4 Nf4+ 27.Kh2 gxh5 (27...Nxh5) 28.Rxe8+ Rxe8 29.Bb6 d5 30.Kg3.

We were both master rated correspondence players, but we both overlooked 22...Nh1. There must be many old correspondence games that contain undiscovered tactical tricks.

Why Did White Lose in Reshevsky - Smyslov 1945?

The next game in Smyslov's Sparklers is the second game of the Smyslov - Reshevsky mini-match on board no.2 of the 1945 USA-USSR radio match. Smyslov won the first game with White and it's a safe assumption that Reshevsky was looking to even the score.

I've played through the game several times. It's a complicated Slav Defense, a real example of chess at the highest level. It's at such a high level that I have a big problem with it -- I don't understand why Smyslov won. My first suspicion was that Reshevsky lost in the opening. Since I don't play 1.d4 very often, and have never been a big fan of the Slav as Black, my knowledge is severely limited.

In the diagrammed position (after 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 dxc4) he played 5.e3, the least popular of the three most common moves in the position. Using Chesslab.com, I found 97 games played since 2002 (Chesslab had a system crash a few years ago and lost many games from 2002) with at least one player rated over 2700. Of these, 94 continued 5.a4, two continued 5.e4, but there were no examples of 5.e3. Is there an obvious problem with it?

[FEN "rnbqkb1r/pp2pppp/2p2n2/8/2pP4/2N2N2/PP2PPPP/R1BQKB1R w KQkq - 0 5"]

Looking at 5.e3, I found 65 games with at least one player rated over 2400 (played since 1997, when the Chesslab database starts keeping track of ratings). Most of these continued 5...b5 6.a4 b4 as in the reference game. About two-thirds of these continued with Reshevsky's 7.Na2 rather than the main alternative 7.Nb1. Now after 7...e6 8.Bxc4, I found three moves played with about equal frequency: 8...Nbd7, 8...Bb7, and 8...Be7. I suspect that these moves are largely interchangeable and a few searches convinced me that this is probably true. Kasparov thinks 8...Bb7 is more accurate, but that's not the issue here.

Smyslov played 8...Be7, and the game continued 9.O-O O-O 10.Qe2 Bb7. Here I found a total of 23 games that reached this position (by players at all levels). A quick look through the games convinced me that White has a satisfactory position, maybe even a slight advantage.

If Reshevsky didn't lose the game in the opening, where did he go wrong? I'll continue the analysis on another post. To play through the complete game see...
