Is there a Custom Map to practice defending against specific cheeses?
Solution 1:
i'm not sure if you can tell the ai to do a build order(but i'm leaning to 'no') but maybe you can just spawn a certain number of zerglings after a certain point in time then make them attack your base? you can also force spawn buildings and a number of workers(to simulate the normal ladder game) and then leave it to the ai to carry on from there
