1. Can you guys give me a good 3 colossus push build againts terran?
2. When I try to go for a macro opening againts Terran such as getting a colossus againts the 10 minutes push... How do you defend from 2 raxes w/ addons? If I do defend it I scrapped my build of about 2-3 minutes lol. So all my tech is delayed and it shouldn't happen.
1. It's not really a definite order or timing, it's the aggregate unit count you're looking at. If you're feeling greedy, I've seen people go Gate - Core - Expand - Robo - Gate - Gate - Robo Bay, and get their first Colossus off the back of 2 Sentries and a Zealot. Of course, if the Terran DOES do some sort of early pressure, he will mess you up hard, but that's why it's 'greed'.
In regards to the 'push' itself, it's going to depend heavily on what time his Medivacs come out, when he's switching to Viking production, and whether or not he takes a third. You CAN push as early as with your first Colossus (but the lack of Thermal Lance may hurt you, or if he has enough Marauders to risk sniping it), or wait until you have 3 with Thermal Lance and about 130-150 supply of stuff. Test the range of Colossi numbers and then watch your replays to see when you should be delaying for more units and when you should be just going for it.
2. 2-rax pressure is DESIGNED to halt your tech and force you to play a different game. Unless you scout it early, you have to accept a significant delay in your plan. Remember that his expo and tech is likewise delayed (of course, that tends to be good for him because small numbers of Marine/Marauder eat Gateway units for breakfast), so keep getting Sentries and Stalkers to fight off the packs and just try to avoid too much economic damage. You'll need at least 3 Gates or quick Immortals to defend the pushes from the Terran, but in general both sides are just going to be walking a razor's edge of unit control to keep their opponent pinned back. Once you have enough Sentries and other units to not worry about your front, make sure you guard against drop attacks and speed your way to your chosen tech path (in this case, Colossus), because you need to restore your game plan. However, this is ONLY after you have defended everything.
