KK On the button

[PatJ]

I've got KK on the button, All fold except 1 who raisies, i 3bet, SB and BB complete, and raiser calls. Flop rags... check to me and i bet, all call. Turn's an ace, checked to me again, i just check. Rivers a jack, checked about, i bet, 2 calls.

Should i have bet the turn, my fear was a Check Raise
