This is a hydra/ling timing reynor did while grinding to #1 on korean ladder. This is likely a bit map specific, but if he can beat the top of the ladder with it, you can beat diamonds with it. It was used against a hero build (2 oracle blink pressure) to great effect.
Why is there no SALT encoding or Overwolf build?

| 4:10 | | Spore each base | |

| 5:30 | | Total of 5 gas | |
| 5:45 | | Get the hydra speed upgrade | |
| 6:00 | | You should have full 3 base saturation minus 1 gas. Build a lot of zerglings for defense, hydras when you can. Don't build any more drones. | |
| 6:40 | | Overlord speed | |
| 7:30 | | (Dropper lords) Fill them with zerglings, push the front and drop in the main. Bobs your uncle. Hydra range behind it. |

This build leans more towards all-in than timing attack, but since its off the back of 3 base saturation and a 4th for larva, its hard to call it an all-in. The advantages it has is killing a protoss before you get to the death ball phase.
