If 3...R - Kt 2 ch; 4 K - B 6 leads to a position similar to those in Examples 40 and 41.
| 4. Q - K 4 ch | K - Kt 1 | |
| 5. Q - B 4 ch | K - R 2 | |
| 6. K - B 6 | R - K Kt 2 | |
| 7. Q - R 4 ch | K - Kt 1 | |
| 8. Q - R 5 |
and we have the position of Example 40 with Black to move.
Let us go back again.
| 1. Q - Kt 5 ch | K - B 1 | |
| 2. Q - Q 8 ch | K - Kt 2 | |
| 3. K - Kt 5 | R - B 6 |
The best place for the Rook away from the King. 3...K - R 2; 4 Q - Q 4, R - Kt 2 ch; 5 K - B 6 would lead to positions similar to those already seen.
| 4. Q - Q 4 ch | K - B 1 | |
| 5. K - Kt 6 |
5 Q - Q 6 ch, K - Kt 2; 6 Q - K 5 ch, K - B 1; 7 K - Kt 6 would also win the Rook. The text move, however, is given to show the finesse of such endings. White now threatens mate at Q 8.
| 5. ........ | R - Kt 6 ch | |
| 6. K - B 6 | R - B 6 ch | |
| 7. K - K 6 | R - K R 6 |
