Zerg - All in Speedling Rush

Here's the first strategy I'm gonna let you guys know about. It's pretty common and is done quite often, especially in lower leagues. This will, however work on most non-walling toss or zerg players no matter what level they are at. It's a no-no for terran because they will wall your lings out.

So first of all, make all the drones you can constantly until you hit the food cap at 10. Once you hit 10, wait for 200 minerals and do what is called "10 pool". This merely means that you get 10 food and make a spawning pool. After you have completed this, make another drone immediately when you hit 50 to replenish your food cap. Then make an overlord as soon as you hit 100 minerals. 

Then, once you hit 25 minerals, make an extractor. This will free up a spot for food, so once again when you hit 50 minerals pump out another drone. Once the overlord finishes, pump out a couple more drones. When the extractor finishes, immediately put 3 drones on in so you can get the maximum amount of gas out of it.



Now that the beginning is out of the way, it's time to make the zerglings. From this point on, you should not make anymore drones at all and instead focus entirely on zerglings. Keep making zerglings until you hit about 14-15 food. At this point you want to save up, or if you have enough, start production on your first queen. After the queen you'll need to get an overlord out to help with food. 

Once you hit 100 gas, immediately put those 3 workers back on minerals and upgrade zergling speed. At this point you should be raking in a lot of minerals and have a decent amount of larvae or have larvae spawning. Always make sure your queen spawns extra larvae. Just keep pumping out zerglings from this point on. I like to usually attack with the initial 6 to feign a small rush or even to catch them off guard sometimes, then I like to rush in with the inital army of completed speedlings.

If the game drags on a bit and you are left with a large surplus of minerals, it would be worth your while to make another hatchery so you can get that little extra larvae boost.

This works very well against other zerg opponents, but is hit and miss with protoss. If they do the choke point wall in, DO NOT use this strategy. As with every strategy, proper scouting is key to make sure the opponent is leaving you with a viable chance of rushing him. Scout, scout, scout! It's extremely important. Remember, this is an ALL IN strategy. If it fails, you will have no alternative and will most definitely lose. Thanks for reading. Good luck!
