I don't have enough practice as Protoss, and playing often had situations when opponent retreats... and I can't catch him. That happens:
- vs zergs: lings just go back
- terran: marines/marauders kite zealots
- protoss: ... don't happen often vs protoss, but still some stalkers run away when I could catch them with zealots...
Ok, I've seen how people make a forcefields line and catch however trying to escaps: lings, roaches, zealots, etc...
I tried to do the same, but it looks like I'm doing something wrong. Usually in early game my composition is stalkers+zealots+sentries. And if I make a FF line my zealots can kill caught units... but then a new problem appears: once zealots come to kill those guys, they in turn become in a range of opponent units... and are killed. As a result there is not much value to making a FF line...
Probably I should not get much zealots when I build FF line? Or may be FF makes sense only if I have MORE army...?
Could you please recommend good guidelines how to play with sentries and/or use FF properly?
P.S. Those materials that I've seen have just general information and don't help me a lot.
