That is, until i saw a match btw HuK and Moon at the DreamHack Summer 2011.
HuK didnt go for a FFE, like i thought most toss will do, but went for a 1 gate wall-in and transit to 4 gate.
Moon went for a spawning pool and extractor and early expand and lost to HuK's well executed 4 gate.
Ever since i saw that, i started 4 gating zergs.
Say wad u want abt PvZ, sometimes we need to think away from the standard FFE...
