The Attack Move still overkills! Any better option to kill more than just 2 units??

[bison7509]

I have been watching some of the videos of the top players like Raphael and Kaiser and saw how they amazingly shooting at each other and could kill even more than 3 units at a time. I have been wondering how could they do that.
All I could do is pressing the attack move button and right click on the ground, but I could only kill 2 units (or sometimes just one!) at a time and wasted too much of my damage by overkilling 1 or 2 units :< I don't need 50 skirms to kill just 2 pikemen! Does anyone have or know any tip to kill more units in a shot?

Thank you in advance for your help!

I suppose they're just really good at microing their units

Well you need to splifite. It encompasses selecting small groups of units, and then focusfiring one enemy unit.

"Splits." In large numbers they still attack move, but select multiple, smaller groups of units to attack move, resulting in 3 volleys aimed at 3 different target areas. Most commonnly seen in abus micro.

Of course if the unit you want to focus isn't in front, then you just need a quick and precise mouse to manually drag box ~7 units and click on the target, like focusing changdoes amidst all of China's other units.
