basically, we're in a league where even masters will rush u. basically try a build over and over. if it doesnt work, try try til it works. basically stick to a build whether its forge expand to etc or mine a lot of minerals. you obviously want the mid game and im also in the situation of getting there myself. im advised to not worry about all that and focus on micro and macro. so keep making probes, units and buildings and once u lose, just calm urself cuz after being rushed 3 straight times and losing, you gotta be calm somehow this game is insanely frustrating on ladder.
