That wont work vs a good zerg player, too slow.
Vs zerg:
9 - depot
10 - barracks
12 - barracks
13 - refinery
*acc and fact after this, fact gives faster vessels and acc gives faster medics, its up to u which one to build first.
Vs toss:
8 - depot (wall)
10 - rax (wall)
11 - refinery
100 gas - factory
*either add a second fact as soon as u have 100 gas or make some marines in addition to the tank and attack with 1 tank and 4-5 marines before u add a second fact. Marines + tanks can be used to contain the enemy in early game because u can kill their goons if they try to attack u too early.
Vs terran:
9 - depot
10 - rax
11 - refinery
100 gas - fact
*after this u can tech to either golls+tanks or wraiths before tanks.
Vs toss or terran u should expand at 2 factories, vs zerg u expand a little later.
