how would you guys play this hand? i think i played it well but was wondering if people would play it differently.

Blinds are $1/$2
UTG
UTG+1
MP+1
MP+2
MP+3
HERO=$120 (TAG)
BUTTON
SB=$400 (LAG)
BB

HERO is the CO and dealt AJo
5 folds, HERO raises $14, button folds, SB calls ($13 more), BB folds.

FLOP: Jd 4c 5s
SB bets $6, HERO raises $20, SB calls
TURN: 8d
SB bets $100 puts HERO all in, HERO calls.
RIVER: 2c

SB shows Kd 6d


i know this is probably an easy call for you pros but this probably the first time that things are really starting to click in my head. before i called and went all in, i was thinking that this LAG probably didn't have anything because of the $6 bet after the flop and the amount of time he took before he calls my raise.. that was the deciding factor for me..

can you guys please analyze and let me know how you guys would've played this hand or if you guys have any tips for me..

Thanks!!!
