The tourney requirement says that "In one phase the blocking piece comes out.of the line and in the other phase it is removed from the line" - Can the blocking piece be removed by the line piece itself, though maintaining the same firing line?

If the capture by the line piece is what "opens" the line, this is not thematic. However, if another piece takes advantage of the line this should be OK

For someone not making helpmates often, allow me the question:
A "phase" has to be in the same position, or can it be in twinnings?
Do phases have to be solutions, or can it be a set play also?

I just sent you a schema, but most likely that one is completely unusable if it is without twinning. :-)

Thanks,
Siegfried

The encyclopedia says:
PHASE
Play after the key, after tries and set play each
constitutes a phase of play. A problem with set
play is said to have two phases (the set play being
one phase, the post-key play being another); a
problem with three tries would be a four phase
problem (each try being one phase, with the
post-key play the fourth). Play in different phases
will sometimes relate to each other. (Definition
from FIDE Album.)

I guess in helpmates, there can be multiple keys. I would have thought that twins can constitute separate phases, but maybe of a lesser quality because the separate phases are artificial rather than naturally occurring. But what do I know?

In helpmates a phase means either 1) solution 2) twin 3) set play
