Hello.
I would say the "standard" bo is something like : kubel/volk/volk - T2 or T3 but it depends on the map, on the commander you choose and on the matchup.
Unlike Sc2, you and the opponent share the same ressource-space. In Sc2 it would mean that if you build a new base, it makes your ennemy loose one, which isn't the case.
In COH2 if you get ahead, your opponend is behind in therm of ressources. That mean that your build order is also dependant of the state of the game : how many replacements had to be done, how many squads did you loose, is one luch enough, will a second one completly crush my ennemy.
Basically i feel that you can at least predict your 4-5 first purchase and past that it is a mess where you try to #adapt more than the opponent because the flow of the game dictate whant you can/must build rather than a global strategy you planned long ago (based on your worker count
).
However, there are certain things like in Sc2 that you can predict from the opponent, like a T70 at the 6min mark (false number but it serves the exemple).
If i would be looking for a structure in 1v1 i would rather look for learning the maps by heart, know where green and yellow covers are, what buildings are criticals and the number of windows on each sides. Also i would learn capping orders which is a thing very close to a build order. There is plenty of way to go wrong in this section and doing random craps.
Kozo.
