I have been reading the new "expanded" edition of Zuke 'Em, The Colle-Zukertort Revolutionized by David Rudel, whose work has interested me since I first heard about it over a year ago. As a practitioner and fan of amateur chess analysis, I recognized in Rudel a kindred spirit and admired (in the materials I saw on the web) the evident work he put into helping amateurs to understand the positional themes and patterns of this under-appreciated opening. I was also impressed by the amount of work that he had put into making his books and promoting them, with excellent websites (at zukertort.com, colle-system.com, and zuke-dukes.com -- the latter with a forum where players can share information, games, and ideas) and lots of online materials and videos (see the webliography at the end of this article for details). Now, finally reading his book, I am even more impressed by the quality of the work. His engaging "conversational" writing style, his focus on explaining themes and patterns rather than dumping a bunch of analysis on the page, and his excellent sense of design and presentation have been widely praised. But what impresses me most about Rudel's work is his desire to seek the best approach to playing the Colle-Zukertort and the way he uses the book format to teach it to others.
Rudel's quest for the "truth" about the Colle-Zukertort continues in the present edition, which breaks new ground for those who would understand the best way to play the opening. If you compare Rudel's repertoire to those of several other Colle-Zukertort books, you see right away that he has a lot of new ideas, many of the "why didn't anybody notice that before?" variety. His more interesting breakthroughs often involve adapting ideas from openings that reach similar positions to the Colle-Zukertort but with colors reversed. For example:
- Against the Grunfeld, he recommends a delayed e4 advance that is parallel to a Black line that typically emerges from the Benoni -- compare Garnett - Littlewood, British Championship 2009 to Schlosser - Alburt, Arco di Trento 1981.
- Against the annoying Nb4 idea of the classical main line, he recommends exchanging in the center and playing a3! -- compare Bruzon - Anand, Ciudad de Leon 2006 to Commons - Reshevsky, US Championship 1975.
- As a way of reviving the traditional Colle, he recommends playing it like a reversed Semi-Slav -- compare Persson - Karlsson, Sweden 2006 to Jankovic - Kaplan, Dresden 2007.
Rudel has not only done some innovative analysis, he has given a lot of thought to helping others understand what he has found. I am very impressed by his carefully structured presentation, which creates an excellent scaffolding for even developing players to master the ideas behind his system. Each chapter begins by setting forth the chief problem that White needs to solve in the line under discussion and the analysis and illustrative game that follow form a coherent piece with the idea of that chapter. Where specific lines call for deeper analysis, he has generally segregated that to the "Extra Analysis" chapter to keep from disrupting the flow of the presentation by focusing too much on specific details. And he concludes the book with a number of "Training" exercises keyed to each section and a set of diagrams to remind readers of the "New Ideas" that he has set forth in his book (especially useful for players who have studied and played the more traditional approaches).
Rudel's desire to teach his repertoire to others has led him to write two additional books of training materials that emerged from the original analysis he was doing on the Colle system. The Moment of Zuke: Critical Positions and Pivotal Decisions for Colle System Players focuses on the Colle more broadly and considers critical tactics and positional themes. Its seven modules (each consisting of "Lesson," "Exercises" and "Solutions" with explanations) are typical of his very orderly presentation and cover such critical Colle topics as how to deal with a Black Ne4, when it's safe to attack with g4, and when you can play the classic Bxh7 sacrifice -- or the double Bishop sacrifice. That last theme returns to make up a whole book in Bxh7: Master both sides of chess' most useful piece sacrifice in 5 easy lessons and 116 exercises which focuses exclusively on "The Greek Gift" (not only out of the Colle or Colle-Zukertort but a number of similar structures, including the French and other Queen Pawn openings). You can review some exercises from the book at his latest website, bishop-sacrifice.com. One of my favorite such sacs is Marshall - Stodie, Atlantic City 1920, but I could not find it in the book (an index of games and players would be a helpful addition to future editions.)
There are actually not that many books where you will find tactical and strategic patterns of a specific opening laid out so thoroughly. The only comparable examples that spring to mind are the recent Seven Ways to Smash the Sicilian (which covers seven different sacrificial themes, like its predecessor Sacrifices in the Sicilian) and New in Chess's "Tactics in the ..." series. With the power of ChessBase "position search," it is actually easier than ever to compile example games to illustrate various themes (as I found in writing Mating Patterns: Bishop and Rook and More Bishop and Rook Mates), so you would think there would be more such books.
Returning to the new edition of Zuke 'Em, I think Rudel has made significant improvements upon earlier editions (one of which I actually found at my library for comparison). He has added some sample games with significant annotations and offered some alternative lines to match player styles. But the most salient and important improvement, as he acknowledges, is at the level of proofreading, and he has done an excellent job eliminating errors in grammar, chess moves, and diagrams. I found only one bad diagram (with a Bishop accidentally substituted for a pawn on page 291) and only one error in grammar ("With this in mind, I propose a line inviting Black to take a free move he wish [sic] he did not have" ). And I was looking for error. [Rudel credits proofreaders Graham Stevens and John Wright for the improvements.]
The Colle-Zukertort is not in itself a complete repertoire, and Rudel recommends that readers fill out the rest by following Aaron Summerscale's cult classic A Killer Chess Opening Repertoire, which is due to be re-released in "a new enlarged edition" updated by Sverre Johnsen some time in early Spring 2010. In the meantime, Richard Palliser's Starting Out: d-Pawn Attacks is not a bad substitute, covering part of Summerscale's repertoire in the Barry Attack, the 150 Attack, and the Colle-Zukertort, and only skipping coverage of the Benoni and the Dutch (which you can find material on elsewhere). And there are other 1.d4 Repertoire Books out there to tide you over until the "return of the king" (Summerscale) -- though you might look for Summerscale's video series produced by Foxy Videos and now available from various sources. For those looking for a parallel repertoire as Black, I'd recommend the Nimzo- and Queen's-Indian complex and the French Defense, in which case you might add Play the Nimzo-Indian, Play the Queen's Indian, and How to Play against 1.e4 (on the French) to fill up your chess opening bookshelf.
