> Another exploit was to start building a cheap building in their base area at the start, somewhat far away from the mining line. They would send a ridiculous number of workers to attack your building. So they'd lose significantly more money to lack-of-mining than you did for building and cancelling a pylon or whatever. Similar to this none of the inbuilt AI's can deal with a slow cannon rush. They will hesitate for ages then rush 5 finished cannons. The later Ai's do a little scv tanking and kiting but nothing near enough, they don't even focus down the probes.
