Standard?

PokerStars No-Limit Hold'em, $0.50 BB (9 handed) from (Format: FlopTurnRiver)

CO ($18.45)
Button ($71.05)
SB ($49.50)
Hero ($52.25)
UTG ($44.25)
UTG+1 ($55.50)
MP1 ($56.50)
MP2 ($39.40)
MP3 ($57.05)

Preflop: Hero is BB with T, K.
6 folds, Button calls $0.50, SB completes, Hero checks.

Flop: ($1.50) K, 5, K (3 players)
SB checks, Hero bets $1, Button folds, SB calls $1.

Turn: ($3.50) 9 (2 players)
SB bets $3, Hero raises to $9, SB raises to $48, Hero calls $39.

River: ($99.50) A (2 players)

Final Pot: $99.50

Hero loses to 55 or 99 is my guess

the problem here is what hands would be do this with? you lose to KQ, KJ, K9

would he really have a smaller K? K5 you lose too, so you are ahead of K2 - K4, K6-K8
plus 55, 99.

I may actually fold this hand
