If you're a protoss player, does this look familiar?
Yes, the bullshit "SCV pull before you have storm" strategy. It seems to be the thing now that we see in almost every pro TvP. If it's not that, it's just a really powerful maxout with mass barracks units before the 3rd is fully established and storm is plentiful. So, as a protoss player, how do we deal with this? A few weeks ago, Day9 did a daily on First vs. FantaSy in the OSL Ro16. In said game, First demolished FantaSy's attempts at mine drops, hellbat drops, and easily deflected most of FantaSy's deadly attacks. While I won't focus on the mine drops now (see older blog post here), I will focus on how First managed to parry FantaSy's really strong direct pushes. And I will do so using geometry.
In my crude drawing, I've created 2 examples using blue for the protoss army and red for the terran army. In the top drawing, we see what happens when a protoss player engages a terran player directly in an open field or at a ramp. If we take a minute and ignore viking positioning and stalker positioning and all that, we see that generally both groups engage each other in straight lines. In this situation, the protoss player has templar trailing in the back of the army, meaning that terran can easily spot templar and (with good micro) snipe/EMP the templar. The terran also has plenty of room to spread and kite against zealots/storms/colossus, and this means that terran can also get a good arc (as shown).
HOWEVER, the second example shows a protoss player who pulls VERY far back, keeping zealots/templars on flanks. You can see this in action in the Day9 daily, P2. In this example, the protoss naturally surrounds the terran army and leaves them no place to run. The protoss player also naturally chokes the terran player with how their army moves and how the surround works. In an actual terrain choke, this is even stronger. This particular tactic is SUPER strong and works very very well against these horrible maxed out attacks that feel so impossible. Here is another drawing to further illustrate my point:
As you can see, there's a natural pincer movement you get from moving your main army back. If you were to have your main army at the ramp, you would have a straight line of engagement with all of your templar behind your army. Yes, they would come at slightly different angles, but they would still all come from the same general direction. By pulling back your main army, you're essentially setting up a huge concave.
Anyways, just been thinking about this, especially after seeing bullshit push after bullshit push in professional games and noticing protoss players trying to engage in a direct line. I want to try to focus on this in my play more, and I hope this helps others as well!
:D
