Templar theme


In the latest issue of The Problemist there is a reference to "the Templar theme".

Can anyone enlighten me as to its origin?

Never heard of the Templar Theme, however there's also a reference to 'masked selfblocking', which I think is not quite correct.
A 'masked' effect is one in which the idea becomes evident after a move by the opponent* - in this case the selfblocking effect happens after a move of the queen's own king.
So maybe it should be referred to as 'anticipatory selfblocking'

*Encyclopedia page 272

Edit - I've just noticed the WB is guarding the blocking square - ok so it is White's move - unguarding the square - which affirms the blocking effect.
So 'masked selfblocking' is correct after all - sorry!

Chiming in (since that has potential for my usual
nomenclature-trolling, poor Wieland :-) -
"anticipatory" (D = voraus)
An effect is only completed by a later move of the same side
"masked" (D = maskiert)
An effect is only completed by a later move of the other side
Is that standard usage?
Must the effect be beneficial for that side? (If no, how are
negative later effects called then? Somehow, anticipatory
shooting one's own foot makes no sense, language-wise)

Looking at the h#3 could it be possible to say, that the blocks on f3/f7 are anticipatory AND masked:
"anticipatory" - the effect "block" is completed by a later move of the black king,
"masked" - the effect "block" is completed by a later move of the white bishop.

Of course the use of the term "masked" is quite unusual here, but why not?

'Why not?'
Because it's improper. Of course, poetic metaphor about a single particular problem is OK, but as a general term it's wrong. Especially since the term is already used pretty properly.
