I'm in the sb with pocket kings,

. I have £60 on the table it's 20nl, villian has £20.
It's folded round to him on the button. He 3 xes to 60p, i make it £1.80 bb folds, Button calls.
The flop;

Pot is £3.80, i bet £2. Villian raises to £5 total, so another £3 to call.
I jam. I really don't like this now looking back at it.
I think my thinking was flawed, i'm happy if he folds, and if he calls atleast i have decent equity. I think this is the wrong way to look at it.
The opponent is a good regular, one of the best players at this level.
I think calling the raise is the best option, or check calling. Or check check, betting the turn.
