Nigel Davies is an experienced grandmaster, chess trainer, and former British Open Quickplay Champion. He is highly experienced in chess publishing and an author of several successful chess books, including Alekhine's Defence and The Grunfeld Defence.
"The suggestions of GM Davies in Taming the Sicilian are solid and steer clear of main line theory. Furthermore, the repertoire choices appear very coherent, which should make it easier to memorize and learn. The book is highly recommended for intermediate to advanced players (I would say with rating 1600+)." - Jens Madsen, Chessville.com
