Ok, that chart listed workers as a counter to an attackless (sure... ok...) air unit (WHAT?) and siege tanks in siege mode (almost a good idea... except that I've yet to see a situation where having the workers run away wouldn't be better, unless it's literally a single siege tank and not yet in siege).WarDaft wrote:Lastly, here is a flow chart of some basic counters for each unit. It is based on the in-game help menu, not my personal opinions, so some relations may be out of date:

Note that it is actually much more complicated at higher levels of play, with certain units countering others only if microed properly, and makes no account of group dynamics.
I'd say try some things out, if you start to notice you die a lot to a specific unit (or combination) and can't figure out a counter go to the SC2 forums (or here, even) and ask for help, because no chart is going to give you anything but single-unit-type counters (ok, yea, I guess that chart does ok at that for the most part). Though, I'll admit that in the lowest leagues you may end up seeing quite a few 1 unit type attacks (you'll grow to love these if you scouted them).
It really just takes a bit of practice to get a general feel for it, even against a computer for a bit. Not sure how much the campaign would get you ready for multiplayer, as supposedly there are a lot of units that they added to it that wouldn't be balanced in multiplayer. Even if you start out online, the league system is very nice with how it places you.
