I had another marathon, and damn everything went incredibly well.
For some reasons I played against more Zerg players than the rest, but all used the same strategy against me, and all failed.
The first opponent was a Terran player (actually Random). Problem with Random race players, they don't tend to specialize in one race, thus making them easier targets to handle (don't underestimate though).
The last bunch of players were all Zerg of whom one was a Random race. All of them used Zerglings, Banelings, and Infestors (some used Roaches, and Mutalisks).
My attack against them was Marines and Hellions (of course not just that). The idea of working against their strategy is to use a lot of Macro, as well as Micro. Because you can't hope to just beat them with a massive army.
A more advised strategy would be to use Siege Tanks to keep their Banelings, and Infestors at bay. But I have yet to work on that strategy.
