This book is an essential reference work if you play the Colle-Koltanowski System.
To be clear, it is a monograph on the Colle-Koltanowski System (1.d4 d5 2.Nf3 Nf6 3.e3 e6 4.Bd3 c5 5.c3), which should not, of course, be confused with the Colle-Zukertort System (1.d4 d5 2.Nf3 Nf6 3.e3 e6 4.Bd3 c5 5.b3) – as though anyone would be silly enough to do that. The very idea is absurd! The Colle-Koltanowski is a ‘plain bloke speaking on a radio phone-in’ kind of opening: it makes a sensible argument, initially at any rate. White plumbs for quiet, straightforward development and will only later turn his (or her) attention to active operations in the centre, typically with e3-e4 or Nf3-e5. Even so, the opening has more than a drop of poison and has produced its fair share of sparkling miniatures.
There are five chapters in total and the format is to present most of the detailed analysis within a series of annotated games, and then to end with a summary of variations, findings and evaluations. In chapter 1, Bronznik devotes close to 100 pages to lines involving …Nbd7. Play goes 5…Nbd7 6.Nbd2 and now the king’s bishop can go to …d6 (which is covered in games 1-14) or …e7 (games 15-21), or Black can take a different tack entirely and play 6…Qc7 in order to forestall Nf3-e5 at the earliest opportunity. If Black goes 6…Be7, White will have quite a difficult job to get an advantage out of the opening.
Bronznik considers the other knight development, 5…Nc6, in the second chapter. Against this, White usually takes on c5 and pushes e3-e4, so it seems immaterial whether the bishop is developed on …d6 or …e7 initially (for example: 6.0-0 Bd6 [or 6…Be7] 7.Nbd2 0-0 8.dxc5 Bxc5 9.e4, etc.). Yet 6…Be7 would allow an early Nf3-e5, while 6…Bd6 may well leave the bishop exposed to 7.Nbd2 0-0 8.Qe2!? and an immediate e3-e4 advance; without an exchange on c5 first, that is. As with the more mainstream openings, there are subtleties here too: there always are.
These first two chapters are quite substantial, clocking in at 93 pages and 73 pages respectively, and the theory of both lines seems to be well-developed. Later chapters, however, are slighter. Chapter 3 (13 pages) examines lines where Black plays an early …b6, followed by …Bb7 or perhaps …Ba6, the latter move made possible with the queen’s knight on its home square. Chapter 4 (8 pages) looks at an early …c4 for Black, including the line 5.0-0 c4 6.Be2. An important variation, for it raises the question of whether White can defer the choice of c3 or b3 for a further move. Finally, Chapter 5 (17 pages) considers several ways by which Black can avoid the Colle (of either variety). Let us be clear: it is not advisable to play the Colle-Koltanowski against all set-ups (such as the KID or the QID); you need more than one gun in your arsenal.
Bronznik provides plenty of original analysis and suggested improvements throughout in his notes to the games. He also discusses certain common strategic and tactical motifs arising out of the opening, such as the queenside pawn majority, the isolated queen’s pawn, the Pillsbury Attack and the Bxh7+ sacrifice. It is all very interesting, useful and insightful. His book ends with a bibliography and a comprehensive index of variations: efficient organisation, you’d expect no less from a German publisher.
Speaking of which, the Schachverlag Kania website seems to be down at moment, but a description of The Colle-Koltanowski System: Deceptive Peace behind the Stonework can be found at the New in Chess website here.
