The position given in the last easy lesson showed a Black win when it was White’s turn to play, but it is only a draw if Black had to play first. Let the student add to the diagram the condition “Black to move, White to draw.”
The draw is brought about as follows:—
| 27-23 | 10- 6 | 7-10 | 2- 6 |
| 1- 6 | 19-15 | 5- 1 | 18-23 |
| 19-15 | 6- 2 | 14- 9 | 6-10 |

Here is a neat winning stroke from Sturges:—
Black Kings on 10, 16, 23. (Fig. 23.)
Fig. 23.
White Kings on 9, 19.
Black to move and win.
The win is forced thus:—
10-14, 9-27, 16-32. Black wins.
