Like i said in the terran build post.. it depends what your opponent does..scout as often as possible and keep your scouter alive..i love toss with the new chrono boosting..im playing the crack so its random races..so i get to practice with a lot of them..when playing a zerg if they 9 or 10 pool u should have time to build 3 zealots by the time he gets to ur base with an early harras ling rush..thats it you chrono boost right..like i said before its hard to practice one build against an AI but my basic build is 2 gate 3 to 4 zealots cybernetic core..stalkers one or 2 sentries and early push to harrass. if your playing terran scout and see if they have infantry like reapers marines ect from the barracks..stalkers should do the job..if they tech up to tanks start builing immortals because they own it.. thats all i have for now
