Book excerpt: After the success of his award-winning book ‘Keep it Simple 1.e4’ International Master Christof Sielecki is back. His new repertoire based on 1.d4 has a similar profile: variations that are straightforward and easy to remember, and require little or no maintenance. Sielecki has created a reliable set of opening lines for chess players of almost all levels. The major objective is to dominate Black from the opening, by simple means. You don’t need to sacrifice anything or memorize long tactical lines. His main concept is for White to play 1.d4, 2.Nf3, 3.g3, 4.Bg2, 5.0-0 and in most cases 6.c4. Sielecki developed this repertoire while working with students who were looking for something that was easy to understand and easy to learn. This new 1.d4 repertoire may be even easier to master than his 1.e4 recommendations, because it is such a coherent system. Sielecki always clearly explains the plans and counterplans and keeps you focussed on what the position requires. Ambitious players rated 1500 or higher will get great value out of studying this extremely accessible book.
