Ok,what you do is you use your usual build order of SCV's etc.Then you ONLY build 4 barracks and start pumping out as many marines as possible,then get(after you have about 50 marines)Lotsa vespene gas and if possible try expanding.If u didnt expnad do this in ur base,if u did,do this there.Build 2 Factories and 2 Starports and NOW YOU HHAAVVEE to expand,then get 12 wraiths with cloak and build about 14 siege tanks and lots marines and medics too if u have money.Upgrade marine attack.Now send ALL your forces and flank the enemy with the wraiths.Now keep sending in groups of 4 marines and 2 tanks.It worked for me,and if things get rough,build lots of wraiths and marines and medics and save up about 24 wraiths and 20 marines with 4 medics and attack.

CreepColony's Opinion: Remember to bring detectors, as people like to use dark templar against a tank push.
