The most famous rush in StarCraft history, made by Korean player SlayerS_`BoxeR` while playing against another Korean, [NC]Yellow , in a Korea tournament finals match.
Reminds me of an Undead Shade rush (Shades are the worker units of the Undead race) I watched several years ago between an Undead player versus a Night Elf player.
Worker rushes are one of the riskiest moves in RTS games. You MUST finish off your opponent with the rush, or you risk losing all of your workers for nothing and lagging behind in terms of time wasted and lack of resources (since you devoted most of your worker force into rushing, lesser resources are gathered as a result).
In Boxer’s case, it wasn’t a true worker rush, because he managed to use a few Marines as ranged support. But still, his level of micro is insane: notice how the SCVs were shielding the Marines from Yellow’s Zerglings, while the Marines were blocking off the ramp to prevent Drones from escaping.
Thanks to Egrest for posting about this video in the A4D group chat!
