Playing the flop with a trash hand, pair + backdoor flush

[ElSapo]

Hypothetical ...

You're in the BB with 9 [img]/images/graemlins/diamond.gif[/img]6 [img]/images/graemlins/diamond.gif[/img]

Two limpers, SB completes, you check.

Flop is 4 [img]/images/graemlins/diamond.gif[/img]9 [img]/images/graemlins/club.gif[/img]Q [img]/images/graemlins/heart.gif[/img]

Do you bet or call? If it may be multi-way? Hypothetically, consider you check and there's a bet and a call. Does anyone just bet?

What if the flop is 6-T-Q, one of your suit and you have bottom pair?
