SB: $210.26 (52.6 bb)
BB: $424.52 (106.1 bb)
UTG+1: $447.70 (111.9 bb)
UTG+2: $497.29 (124.3 bb)
MP1: $238.05 (59.5 bb)
MP2: $331.05 (82.8 bb)
MP3: $386.60 (96.7 bb)
Hero (CO): $400 (100 bb)
BTN: $400 (100 bb)

Preflop: Hero is CO with Qc Qs
4 folds, MP3 raises to $12, Hero raises to $36, BTN calls $36, 3 folds

MP3 is a weaker recreational player. BTN is a 23/17 winning reg and his range should be a bit tigher here but I think could still include hands like KQs/KJs/T9s and the like since MP3 is likely to call along as well so it'll be 3way with BTN having position.

Flop: ($90) 3h 5d Ah (2 players)
Hero checks, BTN checks

I choose to check/call my 99-KK here and balance it by check/calling weaker Axs as well as AT/AJ. But villain checks too.

Turn: ($90) 8h (2 players)
Hero checks, BTN bets $48, Hero calls $48

I'm not sure what's best here between betting and check/calling. Check/calling keeps his bluff range wide and I don't think it's out of the realm of possibility that BTN delay bluffs this Ax board. He could also be betting Kh/Qh, which I think bet most of the time when checked to as opposed to seeing a free river. However, I could be convinced that betting is the better play so I don't give any free cards to a marginal/bluff catchy range but if called, I wasn't sure if the river would have been a check/call or check/fold given his range should pretty much be some weakish Ax or KhX/QhX.

River: ($186) 3s (2 players)
Hero checks, BTN bets $148, Hero calls

Villain bets very large here, large enough that I don't think most players would choose this sizing with a hand like AJ/AQ and those hadns may bet the flop as well. It's pretty unlikely he checked through the flop with a FD, a set, or A3 so unless he coldcalled my PF 3bet with A8s or 88, I'm having trouble putting him on a hand for value. My range appears to be rather weak/bluff-catchy and face-up so I would expect him to bet quite large with most of his betting range.
