1/2 Live deep stacked, good semi bluff or spew?

Thanks for the responses. I honestly didn't know if he was prone to call here or not. I just knew that he couldn't possibly have the nuts, and I think I was playing my table image more than I was playing him. I'm considered the tightest player at the table, especially when it comes to omaha because I'm just beginning.

I don't think he would fold the second nuts in hold em, but for omaha I have absolutely no idea. I feel like if I just check here I am giving up the hand unless the board pairs though, something which I didn't want to do. I figured this was either fold or raise.

So pretty much all I can gather from the last two responses is that you don't make this move without solid reads?
