when should u go hold(when how much gold left in mine) from a 1 rax rush on gow?

I say that after you get your lvl 4/5 grunt rush out of 1 rax, and you have your reletivly early mill, you should probably be looking at about 22-23 peons as you go hold. Once you get hold going, I like to try and get 2 raxes once hold is halfway complete (learned this from valk), that way it usually ends up that your orge mound (which gets reped by like 2-4 peons) finishes at about the same time as your 2 new raxes. Immediatly go fort and your now able to pump your orges out of 3 raxes, which will produce a good number quickly. Obviously u want to rep alter and get lust asap. After that I go with a 4th rax and temple (which comes first depends on circumstance). Hope that helped, and sorry if i insulted your intellence by saying stuff u already knew
