Diagram 95.—­White to Move and Win.

At last White has a position in which he can reduce the ending to one of the fundamental cases by exchange.

          (31) 5-14 17-10
          (32) 21-25

It will be noticed that through the exchange Black gained to move.  White regains it by a second exchange.

(32) ... 10-15 (33) 25-30 15-19 (34) 30-26 27-32 (35) 26-22 19-24 (36) 20-27 32-23

and wins.

Second position as a rule results from a “Bridge position” like the following:  Black men on 20, 21, 23, Black King on 26.  White men on 30 and 32, White Kings on 15 and 19.  Black to move: 

(1) 26-31          19-26
(2) 31-22          32-27

and White wins by “second position.”

THE CHANGE OF THE MOVE

By the exchanges of men in the foregoing example the move was altered in each case.  However, exchanges of pieces often occur which do not change the move, and as win or loss in a great number of endings depends upon which player has the move, it is necessary for the beginner to obtain a clear insight into the questions involved.  An exchange always alters the move if the capturing piece is recaptured in turn.  If a different piece is recaptured, it depends upon
