"In chess you cannot take your move back, but you can always return a misplaced piece to its former square at the cost of some time. Pawns on the other hand can never move backwards, making pawn moves truly permanent decisions. This irreversibility makes Pawn Play among the most difficult aspects of chess strategy, which is one reason few books have been written about this topic - and some that have are almost incomprehensible. Double Olympiad gold medalist Sam Shankland has gone the other way - breaking down the principles of Pawn Play to basic, easily understandable guidelines every chess player should know."--Back cover.
