Yeah, you're probably referring to the pretty solid Korean 4 Warpgate allin. The build is fine, but the thing is, if you actually want to get better as a player, you should learn how to win macro-oriented games too. Also, I think the Korean 4 warp-gate is only really effective against Protoss, so it'd be better to learn a safe-easy opening like 2gaterobo or maybe if you're still new, good old 4 warpgate (even though technically it's sort of all-in depending on how far you're willing to take it.)

If you realize the enemy is going K4warp, it's pretty easy to defend. What makes it really deadly is when you don't expect it. There's an entire section of an article on TL about how to defend the K4warp, so if you want to know how, go read it.

FE vs Terran, which has been my standard openner for Terran for like, ever.

Hey Cecil, wondering if you still try that weird sentry FE build still, I think you used it against Zerg, would that still be effective with the roach range upgrade now? (I think it was against Zerg). I never feel comfortable with fast-expanding though, I feel so vulnerable to a fast all-in or something, but I guess that's what scouting is for, but it's still unnerving. Also, Zerg T3 > Protoss. Have watched Cecil lose too many times to ultralisks, such a sore sight when the Zerg overwhelms you with straight power

Yeah I do. The newer sentry FE is the standard FE that high level players are using, so of course I use it! It works against roaches and the range buff doesn't make a difference early on, because your main defense and main damage dealers early on are your cannons. The only time I lose to early pressure with the build is if I don't realize the zerg went one-base heavy aggression. In they case they do do that, you need a lot of cannons and like 4 warpgates asap (after you lay cannons).

And yes, ultras > unmicroed stalkers. However, if you have stalkers + 4 immortals, suddenly ultras fall surprisingly fast, as well as roaches. Roaches can now contest much easier with stalkers, which was the main affect to PvT in the recent patch. Now, 3,3 stalkers with blink aren't as effective against hydras with roach support.

Since I've gotten better, I don't lose to ultras too often as I usually scout the cavern and react with some immortals. Also, I usually have immortals left-over if the Z went for heavy roaches, as if you aren't a moron with your army you won't lose it for a long time in PvZ (unless there is heavy early aggression).
