Finally, after a longish wait, here's the next addition to the Advanced technique guide.
As the meta evolves the strategies in the game evolve too. When the game first came out a common strategy was the double mine. Where you would build 2 mines turn 1. On the smaller maps which we're now seeing more of, the double mine strategy doesn't really work. So what strategy should we be using now? A new, previously overlooked strategy rises up as the new strategy for smaller maps (specifically maps where you can build a pink mine turn 2 and the only pink econ is shared between the players like Zircon or Boombox but not Circles since in Circles there is Pink econ that isn't shared).
That new strategy is... The builder rush (no, it's not cheese).
