The maps with your former placement of troops tend to be Fog of War, while the latter is usually reserved for Standard (and High Funds is basically whatever the fuck the committee feels like adding that day because no one fucking plays High Funds but atrueboss).
The reasoning behind avoiding sticking too many bases for a single players too close to each other is COs that thrive from stalling the match, wait for their SCOPs or otherwise have an advantage building up their unit count and amassing a lot of troops. Out of all of them, Eagle is the most egregious abuser of this tactic, because even if you manage to wall break his units, you have dealt enough damage for him basically having double his unit value for a turn.
Bases are either divided in the
>XZX
>ZXZ
configuration to create a "mixed bases" map (basically one lone, weak and hard to defend base that both players rush to try and capture first)
or in configurations like
>X A ZZ
>
>
>XX A Z
(where A denotes an airport) to ensure that reinforcing your lone base is harder than taking on your opponent's.
By the way, configurations like
>ZXX
>XZZ
are very rare because of First Turn Advantage dictating that, assuming X is P1, he gets to immediately rush the lone base of Z, which leads to boring games.
Layouts like
>XXX
>ZZZ
or
>ZZX
>ZXX
Are much more commong in Fog of War because the fact that you don't really know where the opponent is building up his forces makes it harder to make large scale pushes. Also, fog maps tend to be very symmetrical and with easy to traverse terrain.
