$100NL ring: I raise big on flop w/ TP+FD then check it down??

[DaveyDonk]

I had just sat down a few hands earlier, so no reads/info. I raised the flop thinking I'd take it down, or get reraised and have to play an allin pot in which I would have at least decent equity alot of times. When he flat calls me, I am not sure what to do UI. Comments on all streets appreciated:
