Timing...

[Braler]

I've been reading people talk about how their timing isn't very good and how they need to look for timing in replays and i was wondering what kind of timing do you mean, i want to improve my game and is it like building timing, or attack timing. would like to know so i can look for it

It's just about practicing enough so that you'll get a feel for about when certain things happen. After you've got in enough games, you'll know "Okay, he's probably setting up an expo, better go disrupt it." and "His T2 push is probably ready about now, need to get ready for that."
