Day 2, 70 players left, 54 cash. Chip average 110,000. Blinds 2000/4000 ante 500
I have generally tight/solid image. We are about 2 hours into the day, been at this table for about 45 minutes.

HJ, Hero (71,000) with QhTc raises to 9k
BTN, (130,000) is guy who looks like jamie gold with a cap and looks like a 45 year old dad, is friendly and seemingly loose passive.
BB (230,000), fat asian guy who is very aggressive, and defended his bb v me earlier with 53o. I also saw a short stack shove for 9bb and a larger stack with 30bb flat call. he rejammed QTo. He seems like a bit of a wildcard, but has had success in past. I expect his range to be very wide here.

Flop (~32,000) Qd4c3s, BB check, Hero check, BTN check.
I checked bc even tho btn loose/passive, he seemed like he wud stab at this pot fairly wide. when he does bet, he also generally overcommits and i thought he might bet near 20-25k, and i would just shove versus his 55-TT hands that i expect to bet.
Turn 6d (~32,000), BB check, Hero bet 14k, BTN fold, BB call.
I was happy when BB check/call here. He check/called fairly quickly and seemed content with the situation and sort of it did in a way that implied he thought 'oh standard call.'
River 5h (~60,000). BB pauses for a bit, and leads for 28k. Hero has 45k left.
I know he knows this is a good card for his range. I also look like 77-JJ/weak Qx a lot. He might expect me to stab AK/AJ too as live players with his player type seem to think this a lot too.
I'm not sure how thin he goes for value, but i do expect him to have 65o, 54o, 53o, 55 to call pre flop and on turn like this.
He clearly vbets 32s,42s,62s like this, as well as 76o 74s 73s. I am not sure if he defends 32,42,62,74,73 in off suit version, but thats a lot of combos. He may also have Q7,Q2 for value, but i expect these hands to lead turn sometimes. The way he called turn though, it felt like he has a standard pair + SD to call with.
As for bluffs, I saw someone on day 1 turn middle pairs into bluffs in a spot exactly like this, and i heroed him correctly. He cud have hands like A6, K6, J6, T6,96, 86 as well as A4,K4,J4,T4,94,84 and maybe A3. I do expect him to abuse this spot as i generally get ppl trying to bluff me a lot as a young looking 21 year old. I also think he might over bluff and use all these combos to bluff, and because he's got chips and we are close to the bubble on an obvious scare card. I am getting 3.2-1 also. But, i know he calls smaller connected off suit cards pre flop, not as sure if he calls hands like J4o J6o Q4o T4o etc. He also seemed fairly confident with his turn call, which idk if he would be that happy check/calling 4x on turn.
