infrequently in practical play, keeps the Black Queen tied to her
KB2 and unavailable for the protection of the B at BI.

White wins as follows:

1. KtxB, KtxKt; 2. RxKt, QxR; 3. Kt-B7ch, K-Kt1; 4. Kt-R6 double
ch, K-R1; 5 Q-Kt8ch, RxQ; 6. Kt-B7 mate.

We will now go a step further and turn from "acute" combinations
to such combinations as are, as it were, impending. Here, too,
I urgently recommend beginners (advanced players do it as a
matter of course) to proceed by way of simple arithmetical
calculations, but, instead of enumerating the attacking and
defending pieces, to count the number of possibilities of attack
and defence.

Let us consider a few typical examples. In Diagram 9, if Black
plays P-Q5, he must first have probed the position in the
following way. The pawn at Q5 is attacked once and supported once
