I raised the button with QxQx10h7h i got called from the big blind by a loose player.

Flop comes- 6d2d4s and it goes check, check. I figured a c-bet could get check raised and out of big blind he has a very loose range and this could hit his hand pretty hard. The turn comes and it is the Qh. He pots it and i decide to flat to go for value on the river. the river is the Jh. A blank, so he checked and i bet 2/3 pot. Insta check raise from him. I was really leaning towards folding but there was just so much i could beat here. he could of easily potted the turn with any set. What do you guys think?
