6c7c UTG+1 vs CO Playing this flush

Hi EthanIves,
Welcome to PokerStrategy.com!

Disclaimer: I am NOT a coach!;

Pre: As you mentioned this is really loose for UTG even in 6-max. So folding pre is perfectly OK
If this is fast-fold, you can often steal from UTG just by betting, especially if you have a tight reputation.

On the flop, you have a flush draw and a gutshot -- why not bet here?
You opened from Early position, so Queens are definitely in your range
Since CO called an EP raise, it is possible he does too -- why give him free cards?

OTT -- you really don't want to see a fourth club, and knowing nothing about villain's tendencies, and at NL2 people rarely raise as a bluff I would like to think folding is the correct play here.

If you do decide to call, what possible rivers can help you?
If you would fold to most river cards, you might as well fold now.
If you think villain has enough bluffs in his range, are you willing to stack off with such a weak flush?

Great hand -- I'm really curious to hear what others think...

All the best,
VS

For me pre is fold
Flop is check
Turn is smaller bet and stack off there
