Post power dribble?

How do you trigger this? I think its different from the dropsteps and the step throughs. I saw the AI pull these on me in a game.

there are many tutorials on youtube, just search for "nba 2k11 post moves"

I did a search on youtube for those. I actually have watched those videos entirely. Did not see any that does that "two hand power dribble" though. I only saw step throughs and drop steps.

then try turbo + signature gather while going towards the basket

I think its turbo + shot(stick) while going towards the basket iirc. Since the RS is involved, you also end up doing a hook exactly like that video.

You basically do a step through (turbo + direction) but you MUST NOT have dribbled beforehand, in other words, without having put the ball on the ground yet.

Here's an animated gif of the move (sorry if it's a lil too fast, esp. if you're on firefox): http://i52.tinypic.com/ot3j1v.gif
