### Simplifying the tree of analysis

Dismissing the king as a viable target was easy, of course. Let's see if we can do the same for the queen. The queen is the next in line in the hierarch of value.

[solution]

A point of pressure must be in contact with two targets (immobility due to lack of time) OR it must be in contact with an immobile target (due to lack of space). Otherwise, your opponent has a free move.

In this position, only the points of pressure f5 and d1 meet this condition. Which one of them is best?

The answer to that is fairly simple.
Rf5 adds one attacker to the point of pressure d5 that means that d5 is not outnumbered yet. That gives black a free move to save its pieces.

Qd1 adds two attackers to the point of pressure d5, since it unpins the knight.

This analysis adds a whole new dimension to the simplification of tactics. You just do not look at a potential point of pressure, but you look for a point of pressure that is either connected to an immobile piece OR you look at a point of pressure that is the base for a duplo attack. Everything else gives your opponent a free move.

I didn't see that one coming.
