"Here's what I say.
After you start a D-Throw, hold Back (as in, the direction you'll want to face after the D-Throw is over). Toward the end of the animation (you have a 10-frame window to do everything immediately after this parenthesis), let go of Back, press Grab, AND RELEASE GRAB.
If you don't release Grab before the 10-frame window is over, the grab won't be buffered. In order to make sure that happens, some people only press down on the edge of the Z button (so their finger slides off after you apply pressure), because the position of the Z button makes it take longer to press and unpress normally. I personally switch my unused Jump button (X for me) to Grab and press it like a shorthop." - TheReflexWonder
Please add this to the Chain-grab part.
