[G] ZvT - Get Curious: A Killer Nydus Timing

15 Hatchery
16 Pool
17 OV
@100% Pool - 4 Lings, 2 Queens
25 OV
@100% Queens, 2 more Queens
33 OV
@5 Minutes - 3 Extractors
40 OV
@100 Gas - Lair
@100 Gas - Ling Speed
41 Drones (16 on minerals at each base, 9 total on gas) + 10 supply from Queens and Lings means you stop making drones at 51 supply
@48/80 Lair, Roach Warren
4 OVs
@100% Lair, Nydus, 2 more Queens, Overseer
Baneling nest if 1/1/1 formation is not scouted.
@100% Roach Warren, however many roaches you feel is appropriate! I generally like to get 10.
Nydus in or near his base by around 8:30 and either rally more units or transition.

Phase 1 - As you can see, the basics of this build are, well, basic. You open standard and are able to get your 3rd and 4th Queens up faster and get better mineral saturation due to your delayed gas (compared to Curious' build). This has the added benefit of keeping your gas hidden from the Terran who will normally see any gas made before 20ish supply and assume something fishy is coming. In this case, he'd be right and we would rather he didn't have all that time to make marauders and bunkers.

Most of my focus in refining this build came down the gas timings. It's fairly basic math: you need 800 gas by the 8:30 mark in order to get Lair, Ling Speed, Nydus, an Overseer, 10 Roaches, and an exit worm. At the rate of 100 gas per extractor we can backwards plan from that point to see that 3 extractors popping at 5:30 will generate 900 gas our timing if played perfectly. This 100 gas buffer from our requirement and perfect play allows for a little wiggle room as well as for adapting to what we scout.

One of the most crucial points in this build comes when your Overseer pops. If you scout heavy bio then you must immediately drop a Baneling nest and start making Lings instead of roaches. If you can confirm this by scouting earlier with Lings then you can go with only 8 roaches or so instead and have Banelings ready for your initial attack. In addition to confirming your opponents tech, your Overseer also serves to scout for potential dead space in themain for a Nydus as well as to detect cloaked Banshees. You should have at least 2 OVs by the Terran's base at this point so you can make a second if for some reason you lose the first.

Phase 2
Now for the actual attack!

At this point in the game you should have 10+ Roaches, 6 Queens (4 of whom are coming for the ride), and x number of ling/bling as the situation dictates. Make sure your roaches are front-loaded in the Nydus as you want them emerging first.

Ideally you will get your Nydus in your opponent's main. Some maps are much easier than others (Antiga, TDA, Daybreak, Shakuras, Condemned Ridge, Cloud Kingdom, Entombed all have great corners that can be abused). It really just comes down to the individual game. Luckily this build is almost as strong when you Nydus near the front and you can almost always pop another Nydus in the main while you bust the front.

As your emerges rally out of the Nydus, immediately drop a creep tumor with the first queen that you can. This will improve your maneuverability immensely as the creep rapidly spreads as well as be a general annoyance for the Terran. Getting 3-4 Banelings as quickly as possible will assure that SCV pulls are disastrous and really help your roaches against marine/marauder balls.

If you feel you can press the game to a close right here, simply rally Roaches/Lings to your Nydus and kill him. Otherwise it's time for...

It's also important to note here that many players will, upon seeing your Roaches and acknowledging that Hellions were a bad choice today, send those Hellions to your base to roast lings. Letting the Terran do this is pretty much the only way to make this attack 100% all-in. 3-4 Roaches rallied to your base instead of the Nydus will let you kill these as well as block your main ramp if necessary. Be careful!

Phase 3
...the transition.

Here's what the situation should look like if your push is cleaned up: you have 41 Drones on 2 bases, Lair tech, and a pile of gas starting to build up. Your opponent is behind in econ and even at best in tech and you don't have to worry about him pushing out anytime soon.

Take a 3rd, drop double Evos for melee upgrades, and get your Infestors out. Depending on how much damage you did you may even feel safe to double expand, else you will probably want a macro Hatch. From this point on simply do whatever you do best and deny the Terran's 3rd as long as possible.

A lot of this can be concurrent to your attack. As you will be able to tell from my replays, I tend to float far more resources than I should be as I micro my attack when those resources could have immediately gone towards tech and drones. Still workin' on them mechanics!

http://drop.sc/267605 - An example of the build vs. AI.
http://drop.sc/267968 - My attack does a ton of damage but doesn't kill him.
http://drop.sc/267596 - Alternate build by MLtLykhan where he takes a 3rd before attacking and you can see the Nydus out front.

I will add more as I get more, my replays are rather unorganized and some didn't get saved so this is it for now.
As you can see I could definitely play better but it doesn't even really matter.
