My opponent is Sjrentt, a 650 point Master Protoss player. I'm currently 549 points in Diamond after having offraced my MMR down last season pretty low, apparently.
The reason this game was so intense was because I opted for a low-econ, aggressive opening, and then had to transition into a macro game while having my expansions denied throughout the game by a Protoss with a much stronger economy.
I felt the only way to come back after sitting back and getting my economy going was to go on the ultra-offensive with multiple hotkeys of Roaches, and later incorporate Brood Lords. I tried to catch him out of position a lot, since Tal'Darim is such a huge map, and by doing that I was able to snipe his Cybernetics Core, Templar Archives, and Robotics Support multiple times.
Drop.sc has my APM clocked at 214 (!) for that game, which is pretty ridiculous given it's SC2 apm. In Brood War it was not uncommon for me to average around 270, and I felt a lot of that multitasking coming back during this game.
TL;DR The replay at the top is the most insane multitasking game I've ever played, and I ended up coming from WAY behind against a high-level Master player to win a ZvP on Tal'Darim.
