Experimenting some betsizes and 3-betting at $25 and had this hand come up.

C/O ($22) opens to $.75, I 3-bet sb w/KQo to $2.25, he calls

Flop: 2d5d5x
I bet $2.25, villain raises to $5.25, I call

I don't want to fold because his raise seems so fos. I have the Kd so I can continue on some turns by c/r'ing.

Turn: 7y
check, check

I think about bluffing but feel like A-high can call me here so decide to check.

This hand is a mess. Is 3-betting flop best if I don't want to fold here?
