typical instance.  Here White does not even need to Queen his passed pawn.  The mere threat forces the win.  For the pawn at Kt4 reduces the mobility of the Black King, in so far as the latter must at all times be ready to reach the queening square in as few moves as the pawn, or else the pawn would queen unmolested.  The White King can therefore capture the opposing Bishop’s pawn in peace and then queen his own.

1.  K-K4, K-K3; 2.  P-Kt5, K-K2; 3.  K-K5, K-B2; 4.  K-Q6, and so on; or 1. ...  K-Kt4 KxP; 3.  K-Q6, K-B4; 4.  KxP, K-K3; 5.  K-Kt7, and so on.

Such positions as Diagram 56 are also reached when there are several pawns on each wing.  The stronger side exchanges pawns on the wing where there is a majority until the extra pawn is passed.

The winning process is not quite so simple when all the pawns are on the same wing, because exchanges are of no use unless the King can assume the opposition in front of the last remaining pawn (compare notes to Diagram 53).

In Diagram 57, for instance, White must not play P-B4.  Therefore he can only win by gaining the Knight’s Pawn,

that is, by bringing his King to B5.  This he achieves by forcing the Black King to relinquish the opposition with 1.  P-B3.
