Me providing some coaching for a zerg player on a macro ZvT he played. I provide basic instruction on some macro mechanics to improve on, like better injecting.
More importantly on things like good engagements, decision making/scouting, and transitioning to the units you want and why you want them.
I coach a gold level zerg who has fairly decent macro, we talk about scouting, unit composition, and engaging properly.
Also mentioned is how to transition to a unit composition well, and without dieing.
Fairly long macro ZvT, with some fairly common mistakes made by our zerg player.
I give tips on how to improve, eg: Better engaging of the terran army, scouting his unit composition, and WHY the engagements were bad and HOW he (or you) could realise this before its too late.
