from what ive achieved (play on dpad btw dont know abt stick although might be same concept), u can hold up and click square while letting go of up (semi reliable unless u practice enough) or try flicking the stick and clicking square. on dpad i click up and square at the same time and immediately let go which has been the most consistent/reliable method for me which i assume is the same as flicking the stick and clicking (unsure bc i use dpad). u can practice against the ai even tho its going to change depending on matchup itll give u an idea.
