One game today

I had four hockey games today, so I didn't really have time to play. I tried to play a game before lunch. It was Terran versus Zerg on Shakuras Plateau. I hadn't played on the map in quite some time. I heard there was a bug where a Protoss player could hide a pylon that couldn't be seen when you play. I guess they took the map out of rotation while they tried to fix it. 
 
The game went normally. I tried to go marine marauder, thinking that he would expand. He didn't at first, and pushed with a lot of roaches. I repelled his attack and wanted to push back. When I saw that he had a lot of spine crawlers, I did a drop instead. It went well. I took out some drones, but also his spawning pool and lair. I then pulled most of my medivacs back to my base. I expanded after that. 
 
I thought things were going well. I started to push out again, but I was attacked with a mix of roaches and mutalisks. As soon as I saw the mutalisks, I switched back to my base and made turrets to protect the SCVs. I didn't have enough marines, so the mutalisks killed the marines I did have, and then took free shots at the other units. Since the turrets were almost done, I ordered the marauders and medivac to retreat to their protection. I must've misclicked or something, though, because the marauders started retreating, but the medivacs flew around and tried to heal them instead of retreating to my base. I lost them all. 
 
I started making thors to counter the mutalisks,. I also started pumping out a lot more units. When I pushed for a second attack, he was already attacking my base. I mad as many units as I could, as well as repaired the thors, but I decided to push on with my units. I took out his expansion, then his main. I targeted his spire, roach warren, and baneling nest first, since those seemed to be the most threatening. I then sent my vikings to scout. I found two more expansions. They fell quickly. Finally, I found another expansion, directly across from my base! I didn't scout there, and I thought he'd be crazy to try and hold a base there. Luckily, my opponent didn't macro well, so I faced off, mostly against zerglings. When I watched the replay, he had a lot of minerals and vespene gas, so he really should have morphed a lot of mutalisks while I was trying to take out his base. He also could have morphed extra structures when I attacked his main base. 
 
My macro won this game, but I probably should have lost it. Luckily, my 60-supply army was enough to take out most of his units, and the fact that he never built a spire or a hydralisk den (before I attacked his main) meant that he needed to tech to lair before he could attack the rest of my base. 
 
He was 52nd in  Gold league. Ater this win, I became 1st place in Silver division. I'm ahead by one point, so I don't think 1st place will last that long.
