My question here is about betting the river or not. Im thinking that I missed some value here but I'm also thinking that betting this straight after the terrible river card is a bit thin?
I have no real reads on the villain

PokerStars No-Limit Hold'em, $0.05 BB (6 handed) - Poker-Stars Converter Tool from FlopTurnRiver.com

saw flop

UTG ($9.36)
MP ($6.10)
Hero (CO) ($16.39)
Button ($17.81)
SB ($11.51)
BB ($4.05)

Preflop: Hero is CO with A, Q
UTG bets $0.20, 1 fold, Hero calls $0.20, 1 fold, SB calls $0.18, BB calls $0.15

Flop: ($0.80) J, K, 5 (4 players)
SB checks, BB checks, UTG checks, Hero checks

Turn: ($0.80) 10 (4 players)
SB checks, BB checks, UTG checks, Hero bets $0.75, 2 folds, UTG calls $0.75

River: ($2.30) K (2 players)
UTG checks, Hero checks

Total pot: $2.30 | Rake: $0.10

I thought about betting around half pot, but in the end I checked it back. Is that playing too scared here? And also if I bet and get raised am I calling? Any input would be appreciated!
