A technique in the new game for the Nintendo Wii: Super Smash Bros. Brawl. It's simliar to the jump grabs in Melee. There are multiple ways of doing it: While running, let go of the analog stick and press and shield for as little and one frame and press A. If you don't let go of the analog stick you'll get the full running grab. You can actually do with w/o letting of the analog stick but for that you have to shield for a bit longer. Probably 3-5 frames.
