oskar, its actually super easy to counter. Its a tiny bit harder with zerg and toss since your tier 1 units are melee. But I pretty much stick to terran, and you simply set your rax waypoint to your mineral field until a few rines get there. When you account for travel time, theres no way your reapers beat the villains rines to his minerals.

For zerg if you just have groups of 2 or 3 lings positioned behind your minerals you'll be fine... same thing with zealots. Even with strong micro, the cheese is never worth the economy hit when you face a semi competent villain.
