Nice echo mates. I have a question about the definition. Attack means threat to capture. So, can a piece be deemed to attack when that piece itself is not attacked?

• Daniel Novomesky says:

In Functionary Chess, a piece (Kings and pawns included) can move/capture/check only if it is attacked/guarded by an enemy piece.

• Kjell Widlert says:

An attack (or guard) in Functionary Chess is really observation, so the attack etc is effective even if the attacker/observer is not able to capture (because of pin, or because of himself not being observed by anyone).

2. Nikola Predrag says:

The first part looks simple to understand and sufficient:
“…An attack (or guard) in Functionary Chess is really observation…”.

But the second part brings back the confusion.
A pinned piece could indeed attack although it is not able to capture. This means that it could check.

An unobserved piece does not attack/check although it is able to observe.

(Now, the confusion might keep on growing, unless the ‘observation’ is explained)
