The 15 hatch build on paper does not appear to be that strong. However its main advantage comes from the fact that it appears as a regular standard hatch first build until it is too late and there are tons of speedlings heading towards/arriving at the opponents base. It is a good build because it is difficult to scout and the required response is fairly specific. Lastly, due to being on 2 hatcheries, the 15 hatch all-in can easily deal some amount of damage and be even and proceed to macro and be even.
In short, the goals of the build are:
Delay the first overlord to get a faster first hatchery and spawning pool
Do everything to appear as a standard hatch first build
Secretly mass as many lings as possible and attack as zergling speed is finishing
