I don't like raising preflop here, especially so much. I'd probably just limp keep the pot small. I think you have to check the turn, and try to show this hand down cheaply. It sucks because you will be giving free cards to flush and straight draws. But you might also be behind. You'll have to invest a significant portion of your stack on the turn to make a bet to give improper odds to a drawing hand.
That's the problem with raising here. It creates a big pot, and you feel obligated to protect a probably best hand, but betting costs a large chunks of your stack. If you limped, you could bet 50 on the flop, another 75-100 on the turn and still have plenty of chips left if villain draws out or you were behind already. It's also easy to get away from if you face a big turn or river bet.

I would check behind and call a bet if the turn is a non diamond non king.
