First make sure to get e repectable defense up. Then get all overlord upgrades. Get three evlolution chambers and get upgrades, also get one spire to upgrade crapace. Then make mass hatchers like about 6 to 9. Make Hydarlisks about 100 of them, and about 50 zerglings. After that take the hydras and make about half og them into lurks. After this you must make a whole bunch of overlords. You can make a lot because they cost no food at all. Then load every thing up try to keep it some what organized. Then go staright to the back of their base. As soon as everything is droped burrow your lurks. Then wait for the emeny to come a try and get you and the lurks will take them out. Then keep on moving in and eventually you'll have them dead. You will not need to worry about detectors because you have overlords.

Remember: close in on the slowly and use the lurkers as back up to help.

CreepColony's Opinion: Uhh...I assume you drop your hyras and zerglings as well.
