10-Pool

The 10-Pool is for putting very early pressure on the opponent. It will give you 3 pairs of very early Zerglings without sacrificing as much of the economy as with earlier pools. You also get the Queen early.

When the six first Zerglings reach the opponent, you have to decide quickly on what to do next. If you think you are able to overwhelm him and take the game quickly, keep producing zerglings and rally them to his base. If you can’t break down the wall or think you can’t take him out, switch to drone-production and get an early expansion up.

The 10-pool has some flexibility, as you can choose to finish your extractor instead of cancelling it at 10/10 supply. The gas can be used to either quickly tech up to Lair, or more probably get speed for your zerglings. Remember to pull the drones of the gas after you have gotten what you need, as you need them for minerals. The 10-pool can put you a bit behind economically at the cost of possible early pressure, but you can transition into most strategies with it. If you think you have scared your opponent into turtling, it might be a good idea to get a fast expansion.
