[FT] Battlefield set-up

This is purely about cinematic FT.  A few months ago, I wrote offlist:

One of the comments was:

  And it appears, from other comments that I've heard, that "Mass your
forces into one big fist and bash away" is a favored tactic.   I can
see why that would be efficient and popular, as splitting your forces
invites defeat in detail.  But are there tactics for which you would
enter the board with your forces split?

("Split" here means "separated by at least 12mu and maneuvering
separately".	I'm not talking about contrived scenarios ("your
squadrons will rendezvous at Point X, but you find a BadGuy squadron
already there"), and I'm not talking about operational-level reasons
("Squadron A raids Mars, squadron B attacks shipping, squadron C
attacks Titan naval base"), I'm talking about setting your ships on
the table.)
