Grivas provides a full and detailed repertoire for White against five important openings: the Gr#65533;nfeld, King's Indian, Benoni, Benko and Modern. In each case, he has recommended a line in which he has a wealth of experience, and has played a significant personal role in developing over many years. The recommendations are geared towards posing Black unconventional problems: your opponents will not be able to churn out lengthy memorized variations, but will need to solve problems at the board in positions that are somewhat different in character from those normally reached in these openings. Grivas has also chosen the repertoire so that it forms a seamless whole, and will fit alongside an English or R#65533;ti move-order, in addition to a standard 1 d4 repertoire.
