I am a 25 yr old Asian American but looks like he's 17. Go figure. What's your first thought of me? Joseph Cheong 6-BET bluff range = A-7o right?!

anyways, here are two hands I played recently, tell me what you would do on the turn, not pre-flop or flop.

Hand #1: AKdd (effective stack ~200$)
EP limps, I am EP+1. I raise to 15$. Folds to EP limper and he calls.
FLOP: K97ssx
EP checks, I bet 15$, EP calls.
TURN: 3s
EP checks, I bet 30$, EP check-raises to 75$ with ~125$ behind.
What do you do? What's his range?

Hand #2: T3ss (effective stack ~200$)
EP limps, CO limps, I am button and I limp. blinds complete.
FLOP: TT4ddx
Checks to me, I bet 5$, blinds fold, EP calls and CO calls.
TURN: 8x
Checks to me, I bet 15$, EP calls, CO check raises to 45$ with ~100$ behind.
What do you do? what's his range?
