I don't mind the pre flop raise as you'll get worse to call from a 25/5, I see no reason to raise the flop, seems like a huge mistake as everything folds but Ax which we lose to. I would check call flop and check decide on the turn.

Not a good idea to raise for info. Either you should raise for value (doesnt make sense here) or raise as a bluff (doesnt make sense with this hand or size).

Better to just play c/c and keep all his worse hands in his range.

Preflop raise is obviously solid.

As for the post flop, I agree that raising serves no purpose. "Raising for information" is mostly something you hear in Hollywood movies and it doesn't really make much sense. It's not really a valid reason to raise especially in this particular spot where the villain can easily flat you with every strong hand he has in his range because he can't really represent anything by going over the top. So even if you get a call you have absolutely no idea about the strength of villain's hand and it costs you 10% of your stack. Calling on the flop makes a lot more sense especially given the villain's sizing.
