first 6-max hand: KQs in SB

[@bsolute_luck]

okay this is from my first short 6-max session. definitely nervous and real shakey on preflop stuff and iffy on postflop aggression.

and reads are more difficult for me to adjust since the hand ranges are much larger now, plus the table i'm at is uber-loose/passive preflop and a mix of LAG/LP postflop.

UTG: the basic read i can gather is that his raising range is pretty tight preflop from UTG, calls down with at least 2nd pair, but will fold if dangerous board and seems beaten. hasn't played enough hands with me to think much of what/how i play.

BB is just a loose/passive doofus who typically calls to at least the turn on any draw/pair regardless of board.

I got a little shook up here figuring I was supposed to reraise, but I wasn't sure based on my position plus if villain's hands were semi-tight and BB was coming along for 1 more sb, I'd rather him be stuck in the middle increasing the pot. bad?

good flop for my hand. 3-handed, he can't figure me for a King, plus I have the BDFD if behind to AA,KK, AK. BB is probably drawing really thin here too, so i'm not going to check/raise, but wait 'til the turn.

I figured I'd donkbet this as QQ-TT are drawing thin and might think I'm only semi-bluffing a flush draw rather than a K, and if I'm behind to AA-KK, AK, even if he reraises, I have outs to the flush, and would make the river easier to guess I should fold even though I have TPTK. and, if he only had UI overcards or a smaller pair, it is doubtful he'll bet this turn with 2 other people in the hand, so i'd hate to have this check through.

what do you think? should I play more straightforward or am I thinking pretty well?
