As an example I guess seeing a zerg go mass ling, and preparing for muta but instead getting infestor. By this point, I've sunk a lot of economy into turrets and thors (and the tech to go with it) and instead I'm scrambling to get together some Ghosts. I'm aware of the 10 min muta timing, and others I notice are around 13 and 16 minutes (some of these may just be delayed by opponent macro).

Double gas Protoss is another - I think it's got to be Void Rays or DTs, and usually I'll see a DT rush at this level (it must be quite successful against other Terrans I guess). Not such a big deal if it's a more passive build with extra sentries, as whichever route I take could turn out well for me in the late game.

I guess I was trying to be vague though. I suspect that the answer to these specific things might just be "macro better with a standard opening = win". It might also be better use of scans (knowing what time the Dark Shrine will go down and making better decisions about the scan location) but in many cases it seems there is some other signal that can tell me which one is likely, like the number of tech structures or gateways down at the same point. For example, I was watching TARossi's stream and he made the comment about zerg taking double evo chamber, and what that meant for mutas.

It's not so much that this is the one part of my game I have picked to improve on to get to Diamond, it's just *an* area.
