Since I modified my 7 roach rush seen here:
I figured I'd make a new post to discuss the all-in variation on this strategy.
First off, perhaps some replays are in order:
So, the basic strategy is you follow my FAST 7 roach rush build order with just one small change involving the queen:
Send your first overlord toward the enemy's ramp.
11/10 extractor trick
spawning pool as SOON as overlord pops
drones to 15
extractor (3 drones on this as soon as it pops)
drones to 16
queen as SOON as spawning pool drops
18/18 build a roach warren at the first available 150 min
drone to 18/18
Queen hatches (spit IMMEDIATELY on hatch)
Ok, at -this- point in the build look at your first overlord (the one you sent to the enemy's ramp). Do you see the standard 1 zealot wide doorway with gateway/assimilator build, or some other wall-in that lacks cannons? If so, he has already lost, he just doesn't know it yet. -IMMEDIATELY- RUN THE QUEEN STRAIGHT TOWARD THE ENEMY RAMP - SHE IS SLOW AND WILL NEED THE TRAVEL TIME
Note: If you -do- see a HARD cannon wall behind a full block gateway/assim (no space to run through), keep the queen at home, fast expand, and immediately tech to mutas or hydras while building some spore crawlers to protect against a potential fast void ray or phoenix. Wasting tons of minerals on cannons means he's committed to 1 base for somewhere upwards of 8-10 minutes, so use this time as best you can.
Now, when your roach warren pops IMMEDIATELY start building roaches. You're going to build 7 altogether, rallied outside your enemy ramp.
Mine just a hair more with the drones as the roaches start hatching, pump out another roach or two or some zerglings, and an overlord. You'll have enough minerals for another ling or two after you've begun the attack but no larva at the moment to build them. The 7th roach should hatch around 4:45-4:50. Give your drones just a few more seconds to mine, then grab them all and bring them along as well. [b]NOTE: If performing this strategy VS terran leave at LEAST 1-2 drones at home - it's possible he will kill all the attacking drones and while he may still technically die, he can fly his CC/buildings away and prolong the game indefinitely if you don't have any drones/cash left to tech to mutas.
So, to recap, you now have 1 queen, 7 roaches, and 16 drones headed to the enemy base - with perhaps another roach or two, or some zerglings following behind by a handful of seconds.
The queen will arrive at the enemy ramp around the same time your first 3 roaches do (around 5:15-5:20) - so send them forward and get the enemy to fire his forcefield (he almost always has one sentry at this point). The second he does that, the game is yours. Hold at the forcefield, bring up the rest of the roaches/drones, and rush in as soon as the forcefield dies, slaughting EVERYTHING.
If he has a full wall-off but no cannons (just stalkers and perhaps a sentry behind it) use your overlord to grant sight and snipe out one of the gateways from below the ramp with the roaches (out of range of the stalkers)
Your attack will begin en-force around 5:30, you'll have a transfuse ready to use on whichever roach he tries to focus down, and another transfuse not long after. Rush everything in and attack-move, with the drones providing front-line tank support for your roaches. The queen transfuse means you have the equivalent of 9 roaches attacking, and she's not a bad tank herself, although she is a bit slow. If he is rushing an immortal it will still be roughly 30 seconds away, so just go smack down the pylon powering his robo facility and laugh heartily. Kill the probes if he brings them forward, the pylons if he doesn't. Game over. Almost every time.
I've played a bunch of these now, and I don't think it's possible to stop it with anything except a HARD cannon wall/tech to phoenix/void rays, and if I scout that I simply switch to 2 base muta, pump some extra queens, and attempt to macro/tech up (not a perfect solution, but you've bought yourself several minutes of pure drone production to catch up).
