|White to click on all black pieces that prevent mate|
In order to solve this position, you need to accomplish the following subtasks:
- Identify all squares were white can give a check
- Identify which checking square might be a potential mate
- Identify which black pieces protect the mating square
The problem is, that the task can't be done in isolation. We shouldn't have to worry about potential mate.
What would be the ideal situation?
There are four elements here that are relevant:
- The attacker (the begin)
- The attacking square (the road)
- The target (the end)
- The protector of the attacking square
Identify the attacker and Identify the target are covered by the exercise "Find all attacked pieces" (FAAP) of Chessgym.
Identify the attacking square is covered by FAC (Find All Checks). The target is always the king here, so the attacking square equals the checking square, but that's ok.
You can't do FAC without mastering FAAP.
You can't do IAPP (Identify All Protecting Pieces) without FAC.
This means, the base for IAPP should be FAC and not M1, as it is now.
The same is true for IABP (Identify All Blocking Pieces).
Logically, even Identify the Pinning Piece should be based on FAC and not M1
Only FESCP (Find Escape Square Creating Pieces) is rightfully based on M1.
