Why Lasker never talk about loose piece in his combinations motifs

I really appreciate Lasker's manual, kind of book full of hidden gems for anyone who is not afraid of "treasure mining".

The reading of the book leave me with an interrogation : Why Lasker never mention anything about undefended piece (loose piece) ?

I tried to remove the search of LP from my thought process but I invariably come back with the conclusion that I play better chess with the LP awareness as a tactical target (like the king is).

Does anyone have an idea why Lasker, who wonderfully explains every importants concept never talk about loose piece in his manual ?

How about an example of a position that troubles you?

I don't have any specific example but, in this position, is it better to search immobility of pinned pawn or should we seek to spot the undefended bishop ?

I agree. If a piece have more attackers than defenders, it is hanging. If the number of attackers and defenders are the same (zero is included), the piece is undefended (loose). And if the piece have more defenders than attackers, it is protected.

Lasker define three combinations motifs :

Encircling : when a piece cannot move (pinned, blocked or confined). If the attacker can attack the piece more time than the defender, the piece is lost for it cannot flee.

Geometrical : when pieces are aligned or placed in a certain geometrical shape, a lot of combinations can arise (fork, pin, discovery, etc.)

Function : when a piece have a certain task (defend an piece, block a line, etc.) his power is limited and it can lead to combinations.

Lasker talk about a lot of basics stuff but never mention that we should pay attention to undefended piece. I wonder why... I first thought that paying attention to his motifs was enough but I must admit that checking for loose pieces helps me a lot to identify weak spot in the position, and that apply for both sides.

 Rxc7 looks much better.

I understand, thank you for the advice. I try not to over-complex things but simply train myself to recognize importants elements in a position. But in this process, I also try to improve my thinking.

But just to be curious, in a position where two loose pieces can be forkable (I know it does not really happend at your rating but), do you spot the loose pieces first and see that they can be forked after or do you see forkable pieces and then notice that they are undefended ? I am pretty sure that both of them should simply jump out in a matter of second but I am wondering which one come first and should be focused on.
