I wanna hear your input on s9 vs 9 or 11 on old gow.

I'm no expert, but if you're having trouble at s9 against 9/11 i would start to lust more (get 2 cats), it will look like you are on the defensive, but then start pumping out grunts and level weapons as well as chop out, then attack and maybe that will keep him busy while you expand.

If he's 9 you building cats, so..
If he's 11 maybe try what I said above or find something else that works for you

You also might want to try moving your hall down(not touching those trees to your left)

Also don't let more than 1 peon in your base

And Don't try to tower 11!!
