AP .25/.50 - ok to CRAI the river?

[Lucarelli]

I can somehow relate to the way you played it, but honestly you're just being way too tricky for 0.25/0.50.
On the flop - if you choose to c/r you can make it bigger than 3b, just bet the pot ~7.
On turn - if for some reason you feel villain is calling light, and you can bluff him out, then bet big, i would shove to this bet out of principle. bet 12 like a man if you want him to fold.
If he called you that far he probably has 1010+, now the miracle ace gives you (probably) the best hand, so extract as much as you think he'd call.
