That guy is awesome, I have only been watching the HDStarcraft and Husky videos so far but this guy goes way more into the why and dissecting the decision trees than they do.
I'm Silver ~60 but I was Bronze in Beta. The biggest thing lately has been drone timing - Day[9] suggests that reactive Zerg is the most powerful so long as you react perfectly, so I've been playing more reactively and I've been practicing better drone timing.
Reactive Zerg tries to balance power-droning (making nothing but drones) with reacting to the opponent's offensive postures. Ideally, reactive Zerg should only produce military units right before an attack, and only produce those units necessary to fend off the attack without taking other damage to its economy. Reactive zerg wins mid-game or late-game after their economy blows past that of the opponent.
I'm still in low Silver because I'm trying too hard to play reactive Zerg now... however, it's teaching me to keep growing my economy after the early mid-game. Once I switch back to a somewhat more offensive Zerg, I think I'll have an advantage that I didn't have before.
Thanks! I'm not a Zerg player (I'm Terran), but I thought this insight by Day9 about Zerg was excellent. I'll try to keep it in mind while playing against Zerg. Sometimes moving out and then retreating can be enough to make a Zerg over-react.
