Carlsen's Grand Prix Attacks

In "Aronian Wins Last Amber Chess Tournament" (also at ChessBase), Lubomir Kavalek offers an excellent analysis of Carlsen - Topalov, Monaco 2011, from the recently concluded Amber tournament.  The game saw the Norwegian phenom trotting out the Grand Prix Attack vs the Sicilian, which is a line you do not see a lot of anymore at the highest levels.  In a later game against Anand (discussed in the notes) Carlsen's opening did not fare as well.

The Cochrane Gambit

The Cochrane Gambit against the Petroff Defense (1.e4 e5 2.Nf3 Nf6 3.Nxe4 d6 5.Nxf7!?) is hard to take seriously at first glance.  White surrenders a piece for two pawns and exposes Black's King in the center, but does he really have enough compensation for a whole piece?  You have to do some analysis and look at games to see how interesting White's long term chances are due to his center pawns. In his 200 Open Games, Bronstein claimed that the Cochrane Gambit was "no weaker, in the author's opinion" than the alternatives because "White, with his two mobile pawns, has a long-lasting initiative in the center."  A number of grandmasters have tried the line, even in high-level encounters (see Topalov - Kramnik Linares 1999 or Short - Shirov Dubai 2002).  So you have to think: if GMs are willing to give it a go, it is definitely viable at the amateur level.  


I had never given the Cochrane a close look until I analyzed Mark Kernighan's recent game against it (see game six of the Select USATE games I posted), which helped me to recognize what a fun opening this can be for the first player, leading to very exciting and high stakes games where pawns are used to dominate the opponent's pieces in a very Clamp-like way.


Below is a partial bibliography and webliography of sources devoted to the Cochrane Gambit from the white perspective.  I have generally left off books devoted to the Petroff Defense generally that should include a chapter on the gambit, though these would probably be worth consulting as well.  I should probably also mention that you need to be prepared for the Symmetrical Petroff, where Black plays 1.e4 e5 2.Nf3 Nf6 3.Nxe5 Nxe4!? (and you cannot continue 4.Nxf7? due to 4...Qe7! and Black wins).

Cochrane Books

Any book on the Petroff will cover the Cochrane Gambit, but there are not too many book sources with analysis from the White perspective.  Alterman and Baker offer useful coverage in their books.  

Boris Alterman, "The Cochrane Gambit" The Alterman Gambit Guide: White Gambits (Quality Chess 2010): 117-157.  I have reviewed this book and think it offers a great introduction to the Cochrane, especially for developing players.

Chris Baker, "Petroff Defense" A Startling Chess Opening Repertoire (Cadogan / Everyman Chess 1998): 27-43.  I really like this book, no matter what anyone says about it.  The coverage of the Cochrane is useful.

Gyozo Forintos and Ervin Haag, The Petroff Defense (Macmillan 1983): 107-115.

This just happens to be the only book on the Petroff to grace my shelves.  It offers a surprisingly balanced treatment of the line considering it is written for Black players.

W. John Lutes, Petroff Defense: Cochrane Gambit (Chess Enterprises 2002), 250 pages.

"Author W. John Lutes has become known worldwide for his exhaustive research in chess. In this volume he actually includes two books, a history of the entire Petroff Defense and a detailed analysis of the Cochrane Gambit. The historical survey spans 165 pages. The move than 1300 footnotes in this section underline the depth of the research involved. This includes the pioneer study by Jaenisch and Petroff translated from the 1842 French, and the Jaenisch 1871 German, which has never before appeared in English."

Anatoli Matsukevitch, The Cochrane Gambit (Match Chess 1994), 28 pages.

A simple pamphlet, mostly with games.

Viacheslav Osnos and Nikolay Kalinichenko, "The Cochrane Gambit 4.Nxf7" NIC Yearbook 19 (1991).


Eric Schiller and John Watson.  Survive & Beat Annoying Chess Openings: The Open Games (Cardoza 2003): 211-226.  This is a book you should have if you play the open games as Black or White.  It has lots of useful analysis, including this extensive treatment of the Cochrane, which the authors call "A near-crazy sacrifice" with "many advocates among amateur players."  Recommends meeting Topalov's 5.Nc3 with 5...Be6 6.d4 (6.f4!?) 6...d5! and the standard 5.d4 with either 5...Nbd7!? or 5...c5 6.dxc5 (6.Bc4+ d5! 7.exd5 b5!) 6...Nc6 7.Bc4+ Be6 8.Bxe6+ Kxe6.

Gems from USATE 2011

Lewis - Hart, White to play  

Higgins - Chen, White to play

Most - Meinders, White to play

Vigorito - Miller, White to play

I have annotated eight gems from the US Amateur Teams East (a.k.a. World Amateur Teams) 2011.  You can download the PGN file (so your computer can help you understand any of the puzzles above that confuse you -- they are pretty difficult, I must confess), or download the whole USATE 2011 PGN of games gleaned from TWIC #853 (download zipped PGN or CB file).


Of course, by now everyone knows it was the West Orange Crush taking first prize at the 1,200 player event.  Tournaments in the South, North, and West make the World Team a far-reaching contest.  Those looking to relive the experience can check out quite a bit of video on YouTube, including a long clip featuring the impressive musical performance by Khess (starting six minutes into this otherwise boring video) and overly-complete video of the last round of the bughouse event.  The crosstable shows that I basically broke even (losing only three points), which is about what I'd expected from a 50% score (which was lucky based on my games).

"The Prince's Gambit" in The New Yorker

"The Prince's Gambit" (abstract only) in The New Yorker does a good job of presenting Magnus Carlsen to a general readership.  The story concludes with his desire to do well in the Amber tournament, so it is nice to see Carlsen joining the leaders today.  Worth picking up.

Jeremy Gaige (1927-2011)

According to the The Philadelphia Inquirer, chess historian Jeremy Gaige died in that city on February 19th of emphysema at the age of 83.  His Chess Personalia: A Biobibliography has been an indispensable desk reference for all chess journalists.  Hat tip to Mark Weeks.

Kavalek on Gligoric

Lubomir Kavalek has a great piece on Svetozar Gligoric titled Chess Legend Turns to Music (reprinted at ChessBase), which uses the release of Gliga's new album as the occasion to analyze the wonderful game Petrosian - Gligoric, Zagreb 1970 (which seems to have inspired his own fascinating game Keene - Kavalek, Teesside 1975).  Gligoric's album has previously been discussed at Chessvibes, but I could find no further information.  Likely it will be a while before it is released in the US.  Meanwhile, we can enjoy this wonderful game, which presents a fascinating response to the Bayonet Attack.

Lego Chess Set

Melanie Penola recommends you Build a Chess Set Out of LEGOs, in a way which seems more child-friendly than the Lego Star Wars chess set noted here last year.  I think my son will be inspired by this one.  (Direct link to the Instructables instructions).
