I played this game last night:

I'm pretty sure my opponent was using a map hack. The strongest evidence for cheating is the way he moves/blinks his stalkers to defend against my mutalisks, specifically at about 20:30 and 21:45. Earlier in the game, he blindly made 3 additional cannons to counter my roach attack. He also doesn't scout at all or make a single observer in a 24 minute game.
I opened with a 7 pool, and he definitely should have defended it a lot better if he knew i was 7 pooling. I don't like to 7 pool on shakuras because if they scout first, they can usually wall their nat and get a cannon up in time. I'm not sure why I chose to 7 pool this game, I was probably tilted.
I was favored over this guy. He was plat, my mmr is high diamond, so maybe the blind cannons and not scouting could be explained by him being bad, but this stuff combined with the muta defense seems VERY fishy, despite him not reacting to my 7 pool the way I would expect a cheater to.
If any of you guys watch the replay, let me know what you think. And is it just me or do most cheaters play protoss?
