Preflop
I would go a little bit bigger, at least to 4bb, maybe see if you could push it up to 5bb. It may not seem like a big deal, but check out
Tip: Raise to 4bb instead of 3bb preflop if you want to play for 100bb stacks in
Progressive Bet Sizing.
Flop
I think that betting this flop is a good idea in order to protect your equity. You can get aces to fold, and make money from flush draws and worse pairs, or at least make them pay to continue.

Why Pot Control Is A Bogus Concept from the Red Chip Poker Podcast. They argue that it ignores equity protection, and that equity protection is crucial (amongst other things):
Quote:
Also, it reinforces an erroneous idea regarding the game of poker. It leads players to believe that protection is way less important than it actually is. It’s as if we’re saying, “Okay, we don’t need to protect the equity here. The most important thing is controlling the size of the pot.” That’s absolutely not how poker works.
Turn
I don't think that there's a reason to raise versus the turn lead. At NL2, players are very loose, and in particular overvalue top pair and better, so I wouldn't expect Villain to ever fold a king, especially to a small raise. If, hypothetically, you knew that you were up against a flush draw, raising would be the correct play, but a full pot turn lead is usually a sign of strength and I wouldn't expect to be up against too many flush draws here.
At NL2 and other small stakes games, the generally recommended strategy is to play tight ranges preflop, value bet hard, only bluff selectively, and get out of the way when they display strength.
River
The 2s is a really awful card for you. If Villain did happen to be bluffing, he's probably doing it with a flush draw. And if he happened to have 53, that also gets there. The only thing I can think of that Villain could have that you beat is maybe a bluff with ace high, but that is a very small part of his range, so this is a fold.
It may seem counterintuitive to be folding when you have such great pot odds. You have about 4:1 pot odds, so Villain only needs to be bluffing about 20% of the time for your call to be profitable. 20% isn't a lot, but it's more than small stakes players will be doing. Check out
