I've been watching SC:Broodwar matches and there are tournament legal glitches/bug that some professional players use on their match such as the
Turret Bug, the
Mining scv trick where you can make a unit go through a mineral line or the
Dragoon hold trick where you can make a Dragoon fire slightly faster by moving your Dragoon as soon as it fires then quickly pressing hold position.
Are there any glitches being used legally now in Starcraft 2 tournaments as if it is part of the meta game?
