ATs 5/10PL river play w/ trip A's on rainbow board?

fold. he raised (strong ace) you put yourself in a crap position. raise the turn, and fold to a reraise. dont stack off with AT, when someone pushes on you and you have two aces on the board. you are 99 percent of the time outkicked. dont defend your blinds like in limit. domination will kick your fanny in NL.

don't go nuts with it, but yes that's the idea. check-raise sizeable on such a flop. especially if he raises a lot preflop, odds are he doesn't have it on a smallish board, so even a pot sized check-raise becomes a good play. just don't go firing random second barrels. if you do that you should fold preflop.
