Folding AK on AKx flop to check-raise

[Runge-Kutta]

it's completely reasonable to c-r here if you're SB with any hand or bluff as most button raise ranges are pretty wide.

You're absolutely right about that. This doesn't hit my open Button raising range as hard as I initially assumed it did and with that in mind a c-r bluff from his end is actually pretty understandable. His SB calling range might even be ahead of me on this flop. I'll run some ranges on stove tonight (it's morning here atm). If this is the case though, would he often take this line of action with a AJ-Q? I believe he would nearly always donk or x/c those.

I cant speak for 10NL, as I've only played 25NL+

To be fair, I only picked 10NL for readability. As stated, this is a fictional hand. I'm probably going to start off on 5NL or even 2NL depending on how much tougher the games have become in the last few years.

such a pissy min-raise

This right here shows how much out of the game I have been: when coming up with this hand I thought this was a pretty standard r size. I guess I really have some reading up to do. What would have been a better min-raise size for Villain here?
