General Strategy
Throwing is good for you! It's 1 frame, you have insane pressure control, and given that teching is weird enough that it sometimes just "doesn't work", your air buttons often get to shine. J.K is a valuable tool in your post-throw kit, as it has a large, sweeping range to account for the occasional above-screen toss. Aerial GMW is a slightly more focused option, with the same 4 frames of recovery for 1 more point of damage. Throw > JK is an easy way to crush dissension in the corner, as you can continue to pile on the pressure from the air to the ground (and perhaps to the air again).
Neutral
You have buttons designed for smashing people into cartoon organ puddles.
Defense
When you're stuck blocking, it's generally useful to throw your opponent the second that they're substantially minus. You can also whip out the 2P mash for an easy space-maker.
