i would say this, have a nice force of scouts and corsairs with a little obs. bring atubutors into the action and try to statis a few groups of bc around. if you can find out where his base is try gettign a few reavers in shuttles. (probably a noob tatic but0 attacking somewhere and try to divert his bcs away from his base. then in reaverswith shuttles hallcinate a few shuttles and drop them into his base. main targets should be workers, sci facility with the thing attached, and starports. without those he can't make bc's at least not for a while. good like
