AK getting busy oop

[DJ Sensei]

Kind of a goofy line, but we're deep and I want to balance value and stack protection. Villain has one of those football player special avatars, but doesnt seem to play that well. Kinda semiloose passive play for the most part, no special reads.

So, what would you do differently if anything, and whats your river play since thats the street that matters the most?
