consider this position and the subsequent moves. It is a very good example of proper co-ordination in the management of forces. The game continues:
| 1. ........ | R - R 1 | |
| 2. P - Q R 4 |
White's best move was P - Q Kt 3, when would follow Kt × B; 3 Q × Kt, R - R 6 and Black would ultimately win the Q R P, always keeping a slight advantage in position. The text move makes matters easier.
| 2. ........ | Kt × B | |
| 3. Q × Kt | Q - B 5 | |
| 4. K R - Q 1 | K R - Kt 1 |
Black could have regained the Pawn by playing B × Kt, but he sees that there is more to be had, and therefore increases the pressure against White's Queen side. He now threatens, among other things, R × Kt P.
| 5. Q - K 3 | R - Kt 5 |
Threatening to win the exchange by B - Q 5.
| 6. Q - Kt 5 | B - Q 5 ch | |
| 7. K - R 1 | Q R - Kt 1 |
This threatens to win the Kt, and thus forces White to give up the exchange.
| 8. R × B | Q × R | |
| 9. R - Q 1 | Q - B 5 |
