Subject: Extensions: everywhere or at frontier nodes?

Hi everyone,
an issue that has been on my mind for quite some time is that if extensions
should be done everywhere in the tree or at the nodes immediately before
qsearch.
Take for example the pawn push to 7th (2nd) rank extension.
If we are near at the root (say ply2, ply3, ply4, ...) why extend if we are sure
the search will reach and past well beyond the promotion?
Woudn't it make more sense to make this (and other extensions) at nodes
immediately before qsearch ?
Same thing for check extensions, one reply extension, recapture extension, etc.

Best regards,
Alvaro Cardoso
