i miss bw Zerg =(

really?

alot ways to go around wif toss 4 gate

5RR roach opening
dimaga's +1 speedlings
2 hatch muta lings

n yes 4 gate all in is strong n forces uu to put multiple spine crawlers, but once defended, the game will be your way =D

roaches targeting zeals. lings targeting stalks, as well as some lings to block reinforcement to reach their main pushing army..
tedious job, but u would feel awesome later.

if uu play around more as toss u would understand,
constant producing only gateway units for the push, basicly
1. ur not teching
2. u might cut probe for xtra pylons n unit
3. u wont hv an expansion

but ofcoz uu can say i will go 4 gate jz to pressure n contain n i would macro n tech up, but den, ur force would not be tat big, n wont apply much pressure to the z player

yeah n im refering to the 4gate push which uses famous 3:3:1 ratio.
i find it very very deadly, but once defended, everything kinda goes my way.

T ready up for mass thors gives alot room for Z to tech up n expand, as well as alot room for the z player to harass wif the absent of tanks, thors are lol slow too.

yeah much lesser, but u will never noe
alwiz scout n good decision making helps uu to be cheeseproof=D
