Finally getting around to watching the King of the Beta semifinals; I watched the first two games of Idra vs QXC, and the first Tester vs IntoTheRainbow game
If I played like Idra in platinum/diamond 1v1 I'd get owned all the damn time. I haven't seen many Idra vs protoss games, but it seems like all his games vs terran boil down to early expansions, and 8min later he still doesn't have a good force. If someone attacks him early he's in trouble. If you let him macro it's game over.
I like getting early expansions too, but I try to have some units to deal with early pressure. Like if I'm playing Optimo, I know he's going to put crazy pressure on me early. Pumping pure drones isn't going to work. So getting speedling upgrade asap becomes very important, and a spine crawler at the expansion.
Then when the big unit push comes, you gotta be ready. I've only seen a couple games where Idra was rushed, and he had problems with it lol
