TL has a marine-marauder-medivac-mine guide, highlights:
Quote:
Do not hesitate to lift up all units into medivacs and speed boost back to safety if the Zerg starts to gain a favorable position in battle. The goal of this 11:30 timing is do as much 'free' damage as possible to the Zerg. The objective is too kill creep tumors. Use medivacs and mines to ensure that you do not lose any units.

You will be focusing much less on pushing and much more on dropping (and scouting) when the Zerg goes for an infestor style. Use small groups of marines to push out and kill tumors at the 11:30, 1/1 stim timing, but be ready to flee at a moments notice. Eight marines and one medivac is a great group to do this with. Keep your army active on the map but not on creep. On creep you are very vulnerable to infestors that just out of vision. Be wary of moving up mid-map ramps as they are another location that infestors can abuse a clumped up army due to vision created by the high ground mechanic. Each time you see his army, back off and send a medivac drop into one of his bases.
