It is generally advisable to advance the Pawn that is free from opposition.
1. ........ P - Q R 4.
Black makes an advance on the other side, and now White considers whether or not he should stop the advance. In this case either way wins, but generally the advance should be stopped when the opposing King is far away.
2. P - Q R 4, K - B 3; 3. P - R 4, K - K 3.
If 3...K - Kt 3, then simple counting will show that White goes to the other side with his King, wins the P at Q R 4, and then Queens his single Pawn long before Black can do the same.
4. P - Kt 5, K - B 2; 5. K - B 5, K - Kt 2; 6. P - R 5, K - B 2.
If 6...P - R 3; 7 P - Kt 6, and then the two Pawns defend themselves and White can go to the other side with his King, to win the other Pawn.
7. K - K 5.
Now it is time to go to the other side with the King, win the Black Pawn and Queen the single Pawn. This is typical of all such endings and should be worked out by the student in this case and in similar cases which he can put up.
