Basic Strategy
Geese has an almost 100% ground game, so you don't need to jump constantly, because his ground options are typically better. If the opponent jumps, don't even think about jumping, because Geese can anti-air almost every character in the game by using his cr.C, the Raging Storm super, his counter move for high attacks, and if necessary, '96-Reppu Ken. Geese has his infinites too, but don't play him as if the infinites are the only thing involved in Geese's gameplan. He has far too many other good options besides his infinites that make him incredibly good at doing anything you can think of. Even his most basic BnB combos are able to deal almost 33% to almost 50% of your life. Whatever the case, you can basically play Geese however you want, just bear in mind he's slightly better tooled on the ground.
