Hello guvgang,
I made this video to show you how I play Steve, and how he is GENERALLY being played. Note that different players have different styles and being the very complicated character that he is, other people have very different styles of playing Steve. Fighting Spirit uses lots and lots of ducks to threaten ws moves and do PKB lows from duck-ins, all while being very safe. Heera Malik relies on a lot of big reads and explosive plays, utilizing Steve's entire moveset.
Included in this video are your best buttons in each scenario, how to land more counter hits and utilize B1 better, using his movement, some setups, frame traps, and more.
I hope you enjoy!
