I thought it was going to be a 'Unnecessary as...' in chess thread.
Unnecessary as...in castling when the Queens are off.
Unnecessary as...in calculating after checkmate
(that is why mating combinations are the easiest. no afters, no sting in the tail)
(of course you may have to calculate which hand he is going punch you with if you've swindled him.)
Unnecessary as...in buying yet another book on endings.
Unnecessary as...in reading one of Robbie's posts because he is clearly bonkers.
