using marines, all pro terrans use marines to scout the other player's main army, to get an idea of what the unit composition is. You should always stim in 1 marine ahead of your main army, so you can see what is up ahead. It is better for the marine to get caught off guard than your entire army. Marines can also give you valuable information on baneling landmines and other potential traps you might of walked into. Although you should do it in all match ups it is especially important in TvP and TvZ. Tip 5: The Power of Fake Pushing Keeping your opponent on his or her toes is very important, since if the other player feels too comfortable you will be left in the dust. In the match ups, TvZ and TvP, Terran is more the aggressor as playing the Terran role in the mid to late game gets increasingly more difficult. The dynamics of Terran means we have to be the player that takes the initiative and takes advantage of the defensive nature of Protoss and Zerg. Fake pushing keeps the player locked into a position of defence, sometimes building more units to deal with a non existent push. It helps in the economic battle and costs nothing. The best times to push out from your base is when an upgrade is about to complete. Since units are most powerful when their upgrades just finish, if there is an engagement, you will have the upper hand.
