i was bb and had around $22, SB and chip leader at somewhere around $68

ME dealt[ Kd 6d]
everyone besides small blind folds i check

FLOP [3d 3h 6c]
SB checks
ME bets $2
SB calls

TURN [ 3s ]
SB checks
ME bets $4
SB calls

RIVER [ Kh }
SB checks
ME bets $5
SB raises $10
ME calls and am all in

SB flips over [ 3c ] and wins $45 from pot

i thought since he had such a big chip lead he was either trying to bully the shorter stacks or he hit the 3's full of kings on the river like me and raised...i called thinkin we would split or id win.....should i have known by his bets he had this? should i have bet differently? any comments pleasee
