Example 42.—We shall now examine a more difficult position.

Many players would be deceived by this position. The most likely looking move is not the best. Thus suppose we begin

1. Q - K 5 ch K - B 1
2. K - Kt 6 R - Q 2

The only defence, but, unfortunately, a very effective one, which makes it very difficult for White, since he cannot play 3 Q - K 6 because of 3...R - Kt 2 ch; 4 K - B 6, R - Kt 3 ch draws. Nor can he win quickly by 3 Q - Q B 5 ch because 3...K - K 1, 4 K - B 6, R - Q 3 ch ! driving back the White King.

Now that we have seen the difficulties of the situation let us go back. The best move is

1. Q - Kt 5 ch ! K - R 1

If K - R 2; 2 Q - Kt 6 ch, K - R 1; 3 K - R 6 !

2. Q - K 5 ch ! K - R 2 best
3. K - Kt 5 R - R 2 ! best
