Pandemic shark - Danny Gormally

This book takes a closer look at the Classic mistakes by amateur playersinclude: 1. Moving a piece too often in the opening. This is one of themainstays which we think relates at least partly to the desire to createsomething in the opening, when we would be better advised to focus on simpledevelopment. 2. Impatience. Sometimes amateur players are too eager to changesomething when there really is no need. 3. Overgeneralizing. One of the biggestdifferences I've noticed when comparing professional play to amateur play is thatthe former is much more about concrete calculation - you go there, we go hereand so on - whereas an amateur player will have a tendency to overgeneralizewhen thinking about a position, perhaps because they are not used to the basicart of calculation. 4. Cutting variations off too quickly. Amateur players donot extend their calculation far enough, and thus superficiality tends to kickin. These and other mistakes are explained in the book. Of course itshould be noted that professional players also make these kinds of mistakes.
