Hidden MONSTER!

[Tom22]

I was playing at 2-5 B&M game.

UTG2 $400
CO $600
Button &1600
Hero $1600

I was in the big blind with 4d 6d. UTG2 limped, CO raised to $25, Button called, I called, and UTG2 called. I played hands like this hoping to score big if it hits. Flop comes 3, 5, T , suits are irrelevant. I checked, UTG2 checked, CO bets $80, button calls $80, I call $80, UTG 2 folds. $340 in the pot. Turn comes a 7, making my straight. I check CO bets $100, Button makes it $250, I go all-in.

I knew at this point the button had made a set. He thought for a long time and the laid down 33. I think he would have called if he had a set of T, and maybe with a set of 5. Did I make the right move? Should I had just call, raise a smaller amount or go all-in on the turn? How would you have played it to maximize this hand and why?

I thought it would look suspicous if I had just called.
