While playing a game just this afternoon, I was curious: What are good spots for Overlords to be?
I decided to draw spots that seemed nice on the maps (S3 Map Pool).
I painted them in Yellow. The big circle is the Main base. I always took the Lower Left base, just because I like that one the most

+ Show Spoiler [Typhon Peaks] +
+ Show Spoiler [Shattered Temple] +
+ Show Spoiler [Tal'Darim Altar LE] +
+ Show Spoiler [Searing Crater] +
+ Show Spoiler [Shakuras Plateau] +
+ Show Spoiler [Nerazim Crypt] +
+ Show Spoiler [Backwater Gulch] +
+ Show Spoiler [Antiga Shipyard] +
+ Show Spoiler [Abyssal Caverns] +
+ Show Spoiler [Xel'Naga Caverns] +
Please keep in mind:
~ Remember to use your common sence; Don't put Overlords all over the North of the map when you are South v South in Shakuras.
~ You can plase your overlord Sneakilly around future expansions, but mostly it'll be better to just place them right above the expansion spewing creep.
~ The lines mean that you should just have vision on this area, the better your Minimap Awareness, the less overlords you need over there, these are mostly to scout for Drops.
~ Versus Zerg, place your overlords along the attack patch mostly and near future expansions, no need for thinking about cliffs for safety.
~ DON'T scatter your Overlords if you are not going to contest for Air Control. If you are going to give up on air control, all these Overlords will be easy pickings.
~ Often, Zerglings can fulfill the same role as the Overlords (Scouting expansion/attack paths), but why not put the Overlords with better visionrange and the ability to stay safe all over the map? It saves you a couple of drones!
Overlords are positioned to give you as much 'safe' vision around your base/nat/3rd as possible. All other positions give you easy acces to scouting: either scouting the enemy base or an attack batch (main/hidden).
I hope I helped some players with this. Please mention any positions I missed, I'd greatly appreciate it!
Kind regards,
