SB (VILLAIN 1) $8.18
BB (HERO) $7.29 Jd Th
CO (VILLAIN 2) $23.04

PREFLOP:
MP folds
CO raises $0.25
BT folds
SB calls
Hero calls

I call because Im getting a good price to play with 2 fishy players

FLOP [4h Ts Jh] Pot: $0.75
SB checks
Hero checks
CO bets $0.23
SB raises to $1.40
BB calls $1.40
CO calls

Decide an overcall to keep fish in is best. Was fully expecting a fold from the CO and figured SB has some sort of Jx/Tx raising a weak c-bet.

TURN [4h Ts Jh 3s] Pot: $4.95
SB bets $4.70
BB bets $5.64 and is all in
CO calls
SB calls

Already pot committed might as well shove and grab some extra fold equity. Again fully expecting a CO fold and very reasonable for the fish in the SB to have Jx/Tx

RIVER [4h Ts Jh 3s 6s] Pot: $21.87
SB checks
CO bets $0.89
SB calls and is all in

SB holding Pocket Qs for pair of Queens
BB holding JT for two pair
CO holding QsJs for a flush

Is the overcall on the flop a bad play? Could I have played a better line? Is there any point I should even be considering folding here? I thought the overcall was best to try to keep the CO in the hand, even though I expected him to fold. The only hand I was scared to run into here was a set of 4s and I get blindsided by a backdoor flush.
