Insane GT Ai? I've played Insane SC2AllIn1 Ai, but not sure what is GT, but the one I played gathered minerals about twice the normal amount as well, they've got 3 gateway before i could get 1 gateway, still, they lack of strategy
1) they keep attacking on the same place
2) they are easily distracted by units some minor units attacking their base (eg. one void rays) , they'll be sure to return back home from their assault from this minor trouble.
3) they got lots of minerals and gasses but still they expand quite late
4) they got no minerals for backup, once their nexus, command center, hatchery is destroyed, they got no mineral left to build it again, so it's gg.
anyway, you just need to hold off their first attack, and then counter them with some distraction on their base while having a couple of new expansion to keep up with their mineral production, and then you're both even.
