The Dutch chess opening is one of Black's most ambitious replies to 1.d4, with 1...f5 creating asymmetrical and richly complex play. Mihail Marin is the ideal author to explain both the strategic ideas and the latest theory. Dutch Sidelines covers lines where White does not fianchetto the king's bishop, including options such as 2.Bg5, 2.Nc3 and various gambits. Extensive guidance is also given on how to meet 1.c4 and 1.Nf3 in Dutch style.
