Lesson of the Week

It is week two for one after school chess club, and week one for a chess class for home schoolers. Next week, chess club starts at a school I'm beginning to coach this year. Due to different ages and skill levels, most weeks I will need two problems of the week.

The easy one:

White to move



Slightly more difficult:

White to move

Steinitz Defense

Wilhelm Steinitz, the father of chess theory, had some ideas that seem wacky today. In The Modern Chess Instructor (1889),* he explains why he prefers 3...d6 against the Spanish Opening, rather than the more common Morphy Defense (3...a6) or the Berlin Defense (3...Nf6). According to Steinitz, the Spanish, or Ruy Lopez, offers White no more than equality.
[W]e have come to the conclusion, after careful analysis, that this form of opening is no exception to the general rule, inasmuch as the pinning of the Knight by the Bishop in the early part of the game cannot be of any advantage; and we find now that at the utmost the game can be made even by White against the best defence, which we think is 3...P-Q3.
Steinitz, The Modern Chess Instructor, 1
Steinitz reasons that deploying the knight to f6 deprives Black of an important resource, which he suggests in his "main variation":

1.e4 e5 2.Nf3 Nc6 3.Bb5 d6 4.c3 f5.

White to move


4.d4 has become the main variation today.

This position from Steinitz's "main variation" appears nine times in ChessBase's Online Database. Moreover, Steinitz did not play 4...f5 when he had the opportunity. Instead, he prepared the f-pawn advance and played it in the early middle game.

The oldest game that I could find with Steinitz's 4...f5 was played via correspondence the year following his World Championship match with Gunsberg. There, as in several other games, White met this idea with 5.exf5, rather than 5.d4 as given in Steinitz's book.

Perhaps Steinitz discovered this simple capture between writing his book and facing Gunsberg over the board.

Problem of the Week

School is back in session, and the scholastic chess season begins soon. One of my schools has its first chess club meeting this afternoon. Others begin soon. Each week, I create a small number of chess problems to begin each club's meeting.

This position occurred in Porges - Pillsbury, Nuremberg 1896.

Black to move


The pawn on e6 must be captured, but whether with the f-pawn or by the sacrifice of a bishop requires deeper consideration.

Chess Viewer (Everyman)

Everyman Chess has been publishing good quality chess books long enough that I have accumulated many of their titles on my shelves. Some of my favorites include Garry Kasparov, My Great Predecessors, 5 vols.; John Watson, Play the French, 3d ed.; and Vladimir Kramnik, and Iakov Damsky, Kramnik: My Life and Games. But, Everyman Chess also published what may have been the worst edited book that I've ever purchased from a major publisher, a book that shows evidence of immense need for simple copy editing and that seems as though it received none. Susan Polgar, with Paul Truong, Breaking Through: How the Polgar Sisters Changed the Game of Chess stands as an embarrassment to Everyman Chess. Aside from printing, binding, and distribution, they utterly failed as a publisher.

With this track record, I had some trepidation before purchasing an ebook version of Nigel Davies, Play the Catalan ($19.99) for viewing within the iPad Chess Viewer ($1.99). The three samples provided with the app revealed that viewing games and commentary was functional, although complex variations are not particularly well supported by the Chess Viewer app. It is easier to navigate complex variations in Chess Base, the viewer of choice for Everyman Chess ebooks.

Play the Catalan is less expensive in paperback ($18.96 at Amazon), but weighs more than the iPad, which also contains many hundreds of other books (and currently sixteen chess programs). The advantages of purchasing it in this format include the convenience of the iPad itself, and that acquiring it does not require finding more space on already overcrowded book cases.

Everyman's website lists 125 ebooks, but only 30 appear in the store accessible via Chess Viewer. All these books concern openings, while their list of ebooks available for viewing in Chess Base includes a handful that are not opening manuals, including Jose Capablanca, Chess Fundamentals (algebraic edition).

It seems as though they rushed Chess Viewer through the process without considering the features that might be of interest to readers. Even so, it is a good beginning.

The Introduction in Play the Catalan includes two complete games: Kasparov - Korchnoi 1983, 7th match game, and a game not available in the Chess Base online database, Davies - Brown, 2009. This position stems from the latter.

White to move


Here Davies found a simple winning combination.

Puzzling

Lajos Portisch played 12...Bc5 from this position.

Black to move


Why not grab the horse? Would White make Black suffer after 12...Qxc3?
