PLO5z Top two facing bet on river

Posted 6 years ago

Blinds: $0.02/$0.05 (6 Players) BN: $6.49 (Hero)
SB: $4.76
BB: $8.88
UTG: $6.68
MP: $25.96
CO: $6.18

Preflop ($0.07) Hero is BN with 2 K A Q

3 folds, Hero raises to $0.17, SB raises to $0.56, BB folds, Hero calls $0.39

Flop ($1.17) T 5 9

SB checks, Hero checks

Turn ($1.17) T 5 9 K

SB checks, Hero checks

River ($1.17) T 5 9 K A

SB bets $0.55, Hero calls $0.55

No reads, only few hands with villain.

Should PF be fold when facing 3bet from blinds?

What my logic should be on this river? Is calling losing play here?
