During the Starcraft II ladder stream, I came across this stratedy again, and found it not to be effective. Here’s a replay of that game, so you know what not to do.
As I explain in the video, remember if a game doesn’t load for a player, a timer will count down from 60. If the timer reaches zero, then the person who didn’t lag out wins. There are no “the game didn’t load” issues on battle.net.
