This issue is that on the forums a Protoss player will say "I know how to beat a 7 pool, do X." But if for whatever reason he isn't playing a "correct" or optimal 7 pool, how can we decipher if he has good advice, or just a misunderstood game sense?
I checked the wiki, and there is no official 7 pool build. Here is what i do, and is what I think is optimal. And PLEASE don't turn this into a "how to defend/how to win" thread, as we already have 24 of those. This is strictly for HOW you 7 pool, and why you think its the most optimal.(or proven)
7/10 Make your pool
6/10 Make a drone
7/10 Make a drone
8/10 Make a drone
Now at 9/10, you start saving larva
Right as the pool pops, you do a double extractor trick, while both are forming make 6 lings
Then cancel both extractors.
Now you are at 12/10 supply with 6 lings being made
12/10 Make an overlord
Right when your overlord finishes you have just enough money for a queen PLUS more lings.
Why I like this build? It just feels right. You never really have to wait around forever and save up to 100 for an overlord. Then the queen timing is perfect. you can inject and have enough for a full batch of 10(actually 8 since i think you have to squeeze in another overlord) lings once the spawned larvae pop, really helping your follow up. And even after your queen pops, you have the money to consistently pump lings/drones. The other nice feature about this, is if you run into some brick wall with this build, you can just make 5 drones and crawl your way back into the game. By the time you get the front door, you can determine whether or not you will be able to win with the 10 reinforcement lings, or if you just need to damage what you can with your initial 6/8/10 (depending on map size and distance) and switch it to powering mode.
How do you 7 pool?
Thanks for reading.
