KK, SOP?

[Phoenix1010]

.5/1 NL, Villain is a tad bit fishy, clearly still learning, but doesn't make overly stupid plays. Very much on the passive side on all streets. Effective stacks are $101.

Hero is BB with KhKc
Villain opens UTG+1 to $3.5, MP calls, Hero reraises to $12, Villain calls, MP folds.
*** FLOP *** [8d Qs Jc]
Hero checks, Villain bets $5, Hero calls.
*** TURN *** [8d Qs Jc] [3d]
Hero checks, Villain bets $12, Hero calls.
*** RIVER *** [8d Qs Jc 3d] [Ts]
Hero checks planning to fold, Villain checks behind.
