How to Counter a Gas Steal Prevention

Basically, this video is a quick demonstration of how you can gas steal someone even when they have a probe on hold position to stop you from doing so.

Just go out of vision range, issue a build command on the geyser that you're trying to build on, and watch as your OP probe (actually, this works with every race in every match-up) takes the geyser anyway. This works best offensively, as if you're trying to take a gas defensively (i.e. the enemy worker is holding position at YOUR geyser), then you'll always have vision because of your nexus...but, in this situation, you can just shoo his probe away with your workers anyways.

Good luck, and have fun!
