I've been watching SC:Broodwar matches and there are tournament legal glitches/bug exploits that some professional players use onin their match such asmatches.
For example, the Turret Bug
Turret Bug, the Mining scv
Mining SCV trick where(where you can make a unit go through a mineral line or) and the Dragoon hold trick
whereDragoon 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 or exploits being used legally now in Starcraft 2 tournaments as if it is part of the meta game?
