"Above all, The Grandmaster Battle Manual is packed with Kotronias' personal experience, discussed with refreshing honesty. Amongst many subjects, he shares ideas on how to deal with setbacks, the best way to handle weaker opposition, and how to cope with a crucial last round game." GM Luke McShane , New In Chess   "Reading The Grandmaster Battle Manual is not only inspiring and highly enjoyable - it also emphasizes hard work and the need to be practical." Arne Moll , ChessVibes.
