3 handed mandatory 10$ OTB

HERO/BTN(1200)

V/BB(covers) indian/middle eastern 30-35, have seen him thin value bet 2nd and 3rd pair on a few occasions, has floated Ac7c on K45xxc. probably not 3b enough 3 handed, have seen him call hands like KQs, has called 3bs OOP and folded the flop a few times.

SB folds
BB 30
HERO calls Q9o

HU
FLOP(60) KQ4r

V leads 40
HERO calls

HU
TURN(140) 9o

V 120
HERO calls

HU
RIV(380) 4

V 300

wondering if this is a 3b preflop, think I need to defend flop, turn im lost.

my range assumption OTR is AK/KQ/JT/AQ QQ-KK maybe some hands like AT or AJ with BDFD, although these might be give ups OTR. is this reasonable?

thoughts on raising turn?
