Two pairs oop on turn completing flush in minraised pot

[annex21]

I like b/f turn. I find minraise is often top pair/air not so much flush draws.
In any case, Qx will check behind a lot here and you're not going to get any value if a fourth diamond hits river. Bet to value Qx and sometimes they will have a redraw with a big diamond so you want to charge that.

I think you can safely fold to a turn raise, and c/f river if he calls. I doubt he is betting river with anything we beat.
