TheRagnCajun said:That can be hard to tell, for me at least, by the time I start investing in the build, shortly after my first rax. Only maybe 4 minutes into the game. At least in bronze league, 9 times out of 10 my opponent hasn't even expanded when I get over there with my banshee's at around 7:30-8 minutes in.
I scout, but that early in the game I'm not sure I'm seeing anything that screams 'macro/economy build' unless of course I see an expansion already.
Here's an easy general rule as to whether they're going for macro or an early push:
Early gas - Macro or tech
No early gas - push
If you're playing against zerg, expect a push if he doesn't expand by 20 supply.
If you're playing against protoss, expect a push if he gets his second gateway before a cybernetics core.
If you're playing against terran, expect a push if he gets a second barracks before gas.
