If you are choosing to make 3 observers BEFORE you make a colossus or immortal, by the time your first observer gets to the enemies base you might already have a small to medium force of MM charging up your ramp that you may not be able to defend. I personally like to get first observer scout base while getting an immortal just to be safe.

It depends on the match-up:

PvP: 1 in their base to keep a look out for dt tech. If shrine comes up, get at least one more.

PvZ: 2 and stay active with them (especially useful against burrowed roaches and infestors, and getting rid of creep tumors). You can always scout with hallucinated phoenix though, especially if they get a spore crawler or two (or if they have overseers); you don't want to let your observers get sniped, as that will disrupt your immortal or colossus production.

PvT: 1 very early (most important match-up to get that early scout in, especially to have against cloaked banshees too), and then have a total of 3 or 4 (cloaked ghosts will auto-kill you, and observers can get quickly sniped with a scan and stim or viking).

You're welcome

depends on the situation, but never more than 3 alive at the same time.

Do NOT get 3-4 Observers before teching to Colossus. Observers are very gas heavy, meaning every Observer you have slows down your tech significantly as well as forcing you to wait for them to finish before you can build any other Robo units. One is enough to scout out your opponent before teching. Afterwards, slowly build more, but only when you really need to.

PvP = 2, 1 for your army, one for scouting/his army if he doesn't have an obs.

PvT = 1-3, 1 if you have map control and can leave a probe out from his base -> he's turtling, 2 is to watch his front and one in your army. 3 if for when he's shown cloak. To scout drops I put down pylons.

PvZ = 2, 1 for his army and one for his next base. Best time to attack is when he is expanding and you know when you're going to be attacked.

Try to get away with making as few observers as possible.

Having a minimum of 2 in each matchup early is a must/ One to scout and one as a "defensive" obs. I think 3-4 is safe for the mid late game, investing in too many more than that can be costly though especially if your obs keep getting killed off. In pvp and pvt, I think obs are critical to watch for drops from warp prisms or medivacs, so would recommend 3-4. Against zerg the obs use is a little different for my play, I usually use them primarily for scouting expos and tech throughout the game as opposed to using them defensively.

It depends on the matchup and the playstyle of your opponent. You will tend to get the most for PvT followed by vZ and vP.

In general this is my ob layout:

- 1 to keep tab on army, usually parks at their natural
- 1 to scout his base(s), keep a tab on their tech and worker saturation
- 1 to follow my army
- 1 to patrol around the other half of the map to check for expos

Your ob count should increase as the game progresses, it is completely wrong to say don't get 3+ obs. Which is why its good to keep your robo busy once it's up. However, if your only running on 1 base, getting more than 2 will hurt your gas for other stuff.

Psychological Edge
From talking to friends and my personal experience, I feel less nervous when I have more vision of the minimap, it feels like I have more control of the game and it feels good to know when they move out, attack, expand, tech switch. So if you feel the same way, by all means build more obs (provided you have more than 1 base!), but if you feel your gosu with your star-sense, then use your money for other shit.

In PvT, if my opponent is going bio, my robo is used to make almost only observers because I don't get collossus before being on 3 bases (i.e. I spam observers lol; usually end up with a max of 4-5). If terran goes mech, I only make two observers.

Any more then 1 is nice... as long as you are active with them or use them in common drop paths.

i like 3 minimum, one with my army, one which floats around the opponents base (scouting tech/ups/timing attacks/expo/etc) and one floating around the field checking other things, if i cant get pylons in place to scout drops properly (map dependent) and if i don't feel pressured i'll often spend production time to make another 1 (sometimes 2) to move around scouting drops

I think 2-3 is optimal. Nothing worse then having your obs snipped and then being beatten by cloak banshees or DTs.

Any more then that and your delaying your other robo tech too much

during any sort of macro game you should have at least 3 imo, the more the better if you can squeeze it in without dying

Before reading this thread I actually had pretty much the same revelation last night after I lost a game because I didn't have the vision to see where my opponent had expanded (a hidden, cross map third) and when he was pushing across the map to engage.

I plan on probably going Observer, Immortal, Observer, Immortal, etc, in the early game now to see how it does.
