Day 2 of IPT MALTA, about 200 players left, 153 paid

blinds 1500/3000, ante 400

I played on this table for about 1,5h and seemed pretty tight due to lack of cards and 2 biggest stack on my left.
Everyone have between 30-80 blinds.

Preflop:
UTG fold
UTG+1 - Stefan Jedlicka (acitive with the biggest stack on the table about 240k blinds) raise to 7000
MP1 fold
MP2 Dominik Panka call (with the stack of 98k)
HJ fold
CO fold
BTN (seemed ok with 180k) call
SB fold
BB - HERO about 115k - with Qh2h call

First of all would like to know what is your calling range in this spot on BB (and if it include Q2s couse now i think it could be a fold especially there is no weak player in the pot and it is quite close to the bubble). But even if it should be a fold would be grateful for thoughts on the river as played.

FLOP:
[ 9s 2d 8s ] (34,100)
everyone checked

TURN:
[ 9s 2d 8s 2c ] (34,100)

I bet 19k (i suppose i could bet little bit less but would like to hear your opinion on sizing also)
UTG+1 fold
Dominik Panka calls
BTN fold

RIVER:
[ 9s 2d 8s 2c 7c ] (72,100)

HERO check
Dominik Panka bets 38k

My thoughts:
I would value bet against player which i don't know much about or some weaker player. However i think Dominik has quite thight range calling MP2 with 33bb (and i think it would be something like 88-TT and suited broadways like T9s, JTs, QJs, KJs, KQs, AJs, AQs and maybe some AQo and QTs KTs so i don't see many hands i can get value from (3 combination of T9s) becouse i think he would bet TT OTF. Maybe it seems weird but i actually think my trips is more of bluffcatcher (against missed draws, assuming he check some of them OTF) and i loose to JTs (4 combinations and ocassionally 88-99 which checekd flop, but wouldn't give him too many of these (maye 1 combination of each, having in mind that he has only one player to act behind and and not so dry of a flop) so it would be 6 cominations of better hands.
The question is how often does he check the flop with FD with this stack size and how often does he bluff them OTR especially with this sizing? if he would check FD OTF half of the time and bet them OTR about 2/3 of the time it would be 2 combinations of missed FD and 6 combinations of better hands. if those assuptions would be correct i have +EV call.

Would like to know if you agree with this conclusion or maybe i missed something.

Thanks in advance guys
