Nikolaos Ntirlis is a correspondence IM who has worked as an openings advisor for numerous GMs. His books for Quality Chess have established him as one of the world’s top authors on chess openings, with an ideal balance of theoretical correctness and practical effectiveness.

"It's simply remarkable that there is so much useful information in only a modest-sized book. The author has a knack of finding the ideas that really matter without overloading the reader with superfluous references.I have to admit that when I was allocated this book as one of those to review I imagined something rather tedious, but I was wrong! It's an impressive effort yet again. There is so much new stuff, involving practical choices that don't overload the memory, and yet the plans and thematic middlegames and endgames are also explained. So put away your prejudices, get hold of this book, and you'll realize that playing the Queen's Gambit can be great fun!" -- GM Glenn Flear, New in Chess Yearbook
