This strat is similar to blind catting, as your cats are already in preparation before you’ve even scouted your opponent and you’re still in-time with a normal rusher if you find that they are rushing.
If you see a rush at any point you would cancel/not start the cats, or not start the mill and start pumping grunts from your two raxs or cancel one cat, wall-in and power. Otherwise continue to work towards cats.
If they’re rushing they will not scout your main with a grunt before you find it or there base if you follow the steps below, unless they for some reason cross scout.
If they peon scout you, it most likely means they didn’t dual.
A player can not solidly pump grunts from two raxs right off the bat, so you will not be behind on a rush if you decide to cancel cats and pump a bit late with your stacked gold and two raxs already done.
After practicing this strat alot I find it has the hardest time vs a dual rush, if you scout the dual rush, see if you can block the rax in otherwise I would suggest a straight counter dual.
The below example is for BNE Gow. For Old Gow, you would only need to just pscout 9 and I guess 4/5 since people seem to dual there.
You start 5. First peon scouts your neighbor (if hot then standard nib war). Otherwise then up to 12/2. At home your building like a normal 2 rax rush, and lastly a mill and straight two cats.
After your peon clears 12/2 (If its a rush, dont even start the mill), then go to 8/6 (8/6 and 12/2 must be cleared first because they will scout 5 the fastest), at this point your mill will already be done and your cats started so if you see a rush, just cancel cats and continue to rush.
If its clear continue scouting 9/11. Your peon at this point will most likely be interupted in its tracks around the time you get to s9 if your opponent is rushing.
If you do find a dual you can just begin towering with the scouting peon, when the cats are done and sent up you can equal 6 grunts supporting them with two more on there way. This is an easy win against the dual, as it is really fast and they had little time to prepare (if they even saw your peon scout).
