Before you move out with your main army have ~2 marines or 1-2 helions take xel'naga towers, make sure you have a few scans saved so that once you stat getting close to zerg's position you can scan a LITTLE bit ahead to see where the zerg is.
Having a few fast units OR banshee/viking/dropship moving ahead of your main army is a good way to give away your opponents position, once you see his/her units start siegeing, if you feel unsafe start siegeing and leap frog to zerg's base.
Learn to spread your stimmed marines around to minimise baneling damage, try and keep zerg OFF his/her 3rd if you can, take an aggresive 3rd and make it a planetary (xel'naga gold is a good example of that).
Invest in an extra factory with a reactor to get some blueflame helions in conjunction with your marine/tank/thor/whatever
Mm, very helpful thanks. But what if they have a lot of creep spread? Should i start leapfrogging earlier then normal?
