I went gas first fast banshee. Spotted his 4gate early, picked off his 1st attempts at forward pylon with my scouting hellion. Bunkered up and easily repelled the 4gate. Picked off a good number of probes with banshee, parked a couple of them in the top corner and poked in a number of times through the game to keep him on his toes. I took 3bases to his 2bases, easily stuffed his 2 attacks before countering and steam rolling.
EMPs worked well, I felt like I positioned my ghosts well. I sectioned off a decent area with my tanks when I took my 3rd, but positioning could have been a little better as he was able to walk his army past my line and into my natural where he picked off all my SCV's before I could clean it up.
My spending in the mid game was terrible, I was floating 1200 to 1600 minerals around the 15 to 20 min mark. Really should have thrown down more production buildings when I took the 3rd. I also need to hotkey my engy bay and armoury to help me remember to upgrade constantly.
All in all this was a typical win vs a gold level enemy, but with mistakes which would have resulted in a loss to a decent player.
