Vs toss u should go a 8 depot (wall), 10 rax (wall), 12 refinery, factory when u get 100 gas and then tech to tanks from 1 factory. Make 5 marines in the mean time so u can defend vs goons. Then attack with 1 tank + 5 marines (pull back if he cliffs too many goons) while u keep making tanks. After making ur second factory, expand and make more factories. Then pump out tanks and vultures (the tanks should be ur main force unless he masses zealots) Vs terran u dont have to wall, just do the same 8 or 9 depot (if u wall, 8. If u dont wall, 9) 10 rax 12 refinery 100gas factory. Then u can either throw up another factory and pump tanks and golliaths, or get a starport and get dropships/wraith. U could also tech to 2 starports and pump wraiths (but if u do this, wall). On island maps i like to 4 goll drop. Do a 9 depot, 10 rax (use rax to scout) 12 refinery, 100gas factory, another factory right before the first factory is done, armory and starport when first factory is done, make 4 golls and 1 dropship and drop the enemy's echonomy (works best vs terran) In TvT, switch to BCs + tanks in late game.
