If you play the Colle System you will be grateful to the Author for this book, which addresses a topic rarely dealt with in chess the Colle System against the Dutch defense. On closer inspection, there is no shortage of remedies against this you could play, for example, the Staunton gambit or the Hopton attack, but what happens if you decide to stay in Colle? This is a legitimate choice, because Colle-players want to set it up against all the defenses chosen by Black. With the appropriate adaptations suggested by the Author, you will be able to set the Colle against the three main Dutch Fluid, Stonewall and Leningrad.
