10/20 Weird spot on drawy board

[LAURA74]

MP is 5kaday on Prima. Someone said it was Johnny Lodden but thats only rumors. He is running about 28/20 (1k hands) and I dunno what hes limping.
The turnraise feels extremly strong but what is he supposed to have? Since all the draws I guess he is raising a set bigger.
I maybe should have choosen another line but what do I do here?

I would have probably led out the flop with the intention of 3 betting and pushing any nondiamond turn.

As played, my thinking is "I has 2 pair, I go all in." Minraising doesn't mean he for sure has a set or QJ, there are plenty of hand that you are still ahed of. Get your money in there.
