Fortress Rush in Starcraft 2

After doing this for many weeks (3 weeks) with 80% average success rate, I've decided to share this. I know I am the first to invent this, and now it has spread around the internet.
I've succeeded in optimizing a Terran build that can utilize a fortress rush.

It involves using two probes for gas and the rest to get minerals. Make another base at 400 minerals, and attack before your base is finished.
The timing is in the replay that I have attached. If their base is a long way, you can lift off sooner. Make sure you remember to make the Engineering bay
after lifting off. When you land, put your scv in auto-repair mode, and make the fortress ASAP.
Then, when the fortress finishes, start making scv and repair. Make some turrets in case Voids or Hellions come after you.

Here is another replay with a faster timing, on High Ground map instead of Outpost above. Note that even with Void Rays coming at your fortress, you can alway repair at a faster rate if you have pumped out enough SCV.

Sometimes, you will meet a zerg, and you are not able to land on the creep. In this case, you can utilize the base to contain their troops or to open the ramp for your allies. In many cases, it is enough to force many of them to quit out of frustration. The map here is Megaton.

If you are very close to another another base, you can alternately get gas with one scv, to get the alternate base built faster. Once the new base is started, immediately put two extra SCV to the gas to quickly get gas. Normally, you should land within 5 minutes 10 seconds using two scv on the gas on normal distance maps. With this alternate strategy you can use it on very close maps like Megaton (with your base fairly close to the enemy base), you can land within 4 minutes 30 seconds if you are fast (in this replay, it was delayed 5 seconds to 4:35 because the zealot was blocking the landing zone). In 4 minutes 30 seconds, they don't have enough troops to really damage your planetary fortress base, so you can have a high percentage of success.

One question many ask is, when should I load scv and lift off? On this example, with no delay in building everything, you load when you have gotten 275 minerals and immediately lift off and go to the closest base. While flying it may be around 300 minerals because your loaded SCVs might be carrying 5 minerals each.

Look at the replay for the exact sequence of timing. Note that this replay is a little advanced, with no delay in creation and building of needed scv and buildings.
