As many of you know, I encourage aspiring zerg players to adapt an aggressive style of play. There's no matchup where this more crucial than ZvZ, as the very nature of the matchup is explosive and fast-paced. Open with a 14/14 Speedling Expand to hold off any early pressure while getting fast speed. Instead of droning or teching, continue to mass speedlings off 2 bases with 2queens.

Put a lot of pressure on your opponent if he expands or just use pure ling/spine/queen to hold off his 1base all-in. It's a great way to end the game outright fairly early, but with 2 hatch 2 queen you still have a reasonable economic follow through. Furthermore, your superior ling count will give you complete map control, denying his scouting while you decide whether to drone, continue producing lings, or tech.
ZvZ is my best matchup and I thoroughly standby this build as one of the most fun and powerful ways of playing.

9 Overlord (I do not drone scout in ZvZ)
14 Gas
14 Pool
15 Overlord (Important to position overlords so that you see whether your opponent has expanded or not, also important to make a line of vision with overlords to his base)
15 Queen (Take guys out of gas at 100)
17 2xLings/speed (You must attempt to get into the main with at least 1-2 of these lings to see: is he mining gas, has he made a nest/warren)
19 Go back into drone production until you have EXACTLY 16drones mining at your main 2per patch.
21 Expansion hatchery.
20 2nd queen
22 Overlord
After 22 supply, in most situations you will continue to mass lings and attempt to outright kill your opponent. The execution of this build, however, depends on what your opponent is doing.

The more you optimize your opening, the more lings you're able to produce. This means you need to be very aware of your mining drones, because occasionally 3 will start mining in the further-away patches with only 1 on the close patches. When this happens you need to manually micro one of the excess drones onto the other patch so that all your patches have 2 mining (Again, total of 16 drones) You can do less-safe variations of the build against players that you know don't open early pool, giving you a surplus in lings later on but you will outright die to any early pool. For example:

9Overlord
15pool (Going pool first means a faster queen, more minerals, but slower speed)
15gas
Drones all the way to 18/18
18 Take your 2nd gas and build an evo chamber to get back to 16supply and build your queen, then cancel both buildings putting you at 20 supply over 18. Then build an overlord and take your expansion about 30seconds earlier than if you went 14gas/14pool.
Again, you're sacrificing safety for an increased ling count in future.

It's very important to have your overlord at his natural by the 4minute mark. If he hasn't expanded by 4min, something is up and it might be wise to get a spine(after your 2nd queen) in your base to keep at the top of your ramp. If you can, try to get a ling or 2 into his main to see if he has a bane nest or is mining gas, but scouting no expansion is a big tell.

Against the 14/14 ling bane style, it's important to utilize your superior ling count to your advantage. For a lot of players, 1base baneling will be the hardest to hold with your speedling-only expansion because you need pretty good micro/multitasking. It's important to utilize your superior ling count to your advantage: you have to engage ling vs ling battles as often as possible and pull away your lings when banelings get close. Also, try to find ways to pick off 1 baneling here and there with 1-2 lings. You do NOT want to stay back and defend with your lings at your expansion or ramp, typically, as this is a narrow/enclosed area where one misclick will result in you losing all your lings. Instead, you want to try to take the battle either to a wide-open area or to his base by aggressively looking for situations to counter attack. Be aware that more cunning players will have a baneling or 2 in their mineral line, so keep an eye for this when you do your countering.

If banelings make it into your base, you need to quickly spread out your drones so that you lose minimal drones to his baneling explosions. If you're not good at manually doing this, try hotkeying 2-3 drones on 7, 8, 9, and 0. That way, you can press 7 right-click, 8 right-click, 9 right-click, 0 right-click to spread your drones out very quickly and efficiently (You don't use these hotkeys early on anyway)

When he's coming in for his baneling/ling push, do a counter attack and use 1 spine at the top of your ramp, 2 queens, and reinforcing lings to hold off his push (Trying as best you can to pick off banelings with small ling groups/queens/spine.) Hopefully, you will kill his mineral line with minimal casualties to your drones back at home. Keep in mind you should NOT be droning against any 1base attack.

This is probably one of the easier builds to defend. Again, it's important to scout his expansion by the 4minute mark so you know whether to build a spine. If he's expanding, skip the spine, if he's not, get one. Then basically mass lings off 2 hatch and get your spine down to your expansion. Don't try to engage at his base or try to pressure him, just wait til he gets to your base (because that's when and where your army will be strongest) and defend it easily with ling/spine.

If players are too greedy, they die outright to mass lings and you will get a lot of easy easy wins. However, smarter players will get a spine up or go for very fast roaches to block the ramp. Once you see the ramp walled, you want to continue streaming lings aggressively to mostly focus on killing his hatchery. Once he pulls off his ramp though, stream those lings around his roaches for a good surround and kill them and move into the mineral line. If he keeps pulling his roaches back to the ramp in time and you can't surround, just go back to the hatchery. Sometimes it'll take 2, 3, or 4 attempts until you either a) Kill his hatchery, b) surround his roaches and move into his main to end the game.
NOTE: If they go for roaches off 1base and then expand, you can perform the build with similar execution OR play a more macro-oriented style and go for slightly later roaches. Just be prepared for the destiny style roach/ling all-in.
Examples above: EGIdrA and coLRyze

Strifecro beats me with this style every time with pure ling/baneling and it's probably the best response to a speedling expand. You will still have a superior ling count with my build, but if he's defending well with banes, a spine, lings, and queens, it can be very difficult to win early. Still, you may catch your opponent over droning after he builds 2 banelings and if you snipe those banes with 1 ling you can overwhelm him with your mass ling you can win a good percentage of the time. Also, if you keep him contained in his base he may overproduce defenses allowing you to secure a macro advantage moving into one of the transitions mentioned later in this thread.

Most often, though, you will not kill him and be forced to pull back, at which point you're faced with a problem: If he all-ins with ling/bane as a counter, you need spines to defend as pure-ling won't work vs ling/bane in a defensive situation. My usual response is to get a warren and some drones while I'm pressuring with lings, and make roaches to defend any counter attack. Then if he attacks, I can defend - if he doesn't, I can execute a roach/ling attack.

If he cheeses with a very early pool, run your drones away until your 4 lings come out then defend with lings and drones. If you're scared, get a spine started too but I usually don't. Delay your expansion hatch by building your 2nd queen and an overlord immediately. Once you have a decent ling count and have held all early pressure, take your expo - make sure speed is on the way. Once you hold the cheese, I like to counter all-in because the opponent will be hard-pressed to hold a 2base2queen ling push. However, you can always get speedlings and take your expansion while refusing to allow his expo.

Even if you can't kill your opponent or do damage to the drones, your opponent HAS TO build defense to live. It's impossible for them to lose virtually nothing to that many zerglings, they need very adequate defenses. You'll find you're really not in THAT bad of a position with 2 queens and 1 fully saturated base, as you can easily use one round of larva to almost fully saturate your 2nd base and be just fine. Also, with the amount of lings you have to can theoretically keep him stuck in his base a long time and squeeze out a few drones here and there. The problem with doing this, however, is if your opponent counter attacks and you have no defense but lings, you might be in trouble. I can't tell you how many games I switched over into drone production and lost to a counter-attack, so you need to be active with your speedlings to scout their expansion and how many drones they're producing, and if they overproduce units, you just have to produce units or defense just in case they counter. What I recommend is practicing with adding a drone or 2 sparingly while still making lings, so that your economy is slowly improving while your opponent's is staying the same because he's more focused on defense.

Some transitions include:
1) Getting 4 more drones to saturate gas and build either a warren/bane nest and continue the relentless, all-in style aggression.
2) Droning up a bit (rallied to your expo) and moving into roaches to defend any counters while squeezing out an eco advantage while moving into the macro game.
3) Droning up a bit (rallied to your expo) and getting an evo chamber for +1 roaches and doing an aggressive +1 roach/ling timing attack
4) Droning up, building 2 evo chambers to create a semi-wall at your expansion and mostly producing lings/spines to stop any aggression from your opponent. Meanwhile, you can use your gas to tech to very fast mutas or upgraded roaches.
5) Moving into standard mid-game ZvZ with roach/infestor or muta.
