I played a hand today but I'm not happy with my line. How would you've played this hand? I have to type it out since I play on a bossnetwork so can't insert the HH.
I've played around 150 hands with him, he seem to be a reg but he was a bit spewy, however, I do not think he'd reraise me pre-flop with a too bad of a hand since I have position and we are this deep. His stats at the point was 39/11 and his 3bet was 12,5

1-2 SEK blinds
Hero (717.31) cut off
Villain (555.56) BB

Hero is dealt QdQhAh7d

Hero raises to 7
BB raises to 22
Hero calls

Flop: KhQc3h

BB bets 42
Hero ??

Now I want your opinion, how would you play this hand? We are very deep and we have flopped middle set and nut flush draw, should I reraise him and go with it, even though we are this deep and see it as a cooler if he has topset and we do not hit our flush (or quads), or should we slowplay it since we have the nut flush draw aswell and let him bluff at it, since he will fold the flop quite often to a reraise. at the same time, we want to start building the pot at the flop with a good hand, especially since we are this deep and we need to start building it to get as much of his stack as possible. Give me your 2 cents please

Thank you and have a nice day
