Avro 1938

This classic tournament from the Netherlands constitutes the focal point for this issue. Our authors, in their various columns, put the games of Alekhine, Capablanca Euwe, Botvinnik, Fine, Flohr, Keres and Reshevsky under the microscope.

Plus 18 selected games of the tournament victor, Paul Keres, with analyses by Yannick Pelletier, Michal Krasenkow, Karsten Müller, Emanuel Berg, Igor Stohl, Evgeny Postny et al.

Top tournament: Norway Chess 2020

Top tournament

Magnus Carlsen’s run of 125 classical tournament games without defeat came to an end, but in Stavanger he was victorious, ahead of Firouzja and Aronian. Jan-Krzysztof Duda annotates his win against the world champion, Alireza Firouzja puts three of his games under the microscope.

Moreover, Peter Heine Nielsen, Romain Edouard, Michal Krasenkow and Spyridon Kapnisis comment on the games by Carlsen, Caruana & Co!

“All in One”

All in one

In this issue of CBM, we have two prominent authors dissecting topical opening lines:Anish Giri looks at the Sicilian Najdorf B90: 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Rg1.

And Igor Stohl's object of investigation is the game Carlsen,M - Giri,A 1-0 (Chessable Masters 2020) which features the Semi-Tarrasch Defence D41: 1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 c5.

Object of investigation is the game Carlsen,M - Giri,A 1-0 (Chessable Masters 2020) which features the Semi-Tarrasch Defence D41: 1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 c5.

Erwin l'Ami shows why of late the Philidor endgame has become more attractive for White. Daniel King takes a close look at a new version of the Milner-Barry Gambit with which Carlsen was successful against Harikrishna. And Mihail Marin picks up an idea of Paul Keres in the Leningrad Variation with 7...Nc6.

“The Classic”

The Classic

The trainer of the German national team is happy that this time he can demonstrate to you “one of the most classical games it exists": the game Botvinnik-Capablanca from the AVRO tournament of 1938 may well have become famous first and foremost for its finish. But Dorian Rogozenco explains that Botvinnik’s plan in the Rubinstein Variation of the Nimzo-Indian Defence is not only very instructive in itself but has long been elevated to the rank of a strategic classic: White does not develop his king’s knight to f3 but to e2, in order to prepare the advance of his pawns with f2-f3-f4 and e3-e4-e5. And in fact the pawn which had advanced to e7 was decisive in Botvinnik’s masterly combination at the end of the game!

“AVRO 1938 - Strategy”

Avro 1983

At the time of AVRO 1938 all the subtleties which accompany doubled pawn structures had not yet been recognised. With the help of your strategy expert, Mihail Marin, find the best moves which were overlooked by the finest connoisseurs of the day.
Including several training tasks and an introductory video!

"Move by Move"

Move by move

At the time of the AVRO tournament in 1938 Alexander Alekhine was the reigning world champion. So, what could be more appropriate than to choose for our training a game of Alekhine’s from that tournament, and specifically his win against the predecessor from whom he had wrested the chess throne, Jose Raul Capablanca! Go through the game with Simon Williams. Play like Alekhine: seize the initiative on both sides of the board and with every move tie down the opponent’s options. All the way to total domination and the resignation of your opponent despite a full board!
