why did Celebrimbor allow Sauron?

Celebrimbor might well have had a better idea of who he was dealing with than he let on.

That's my take. Other elves got the sense that there was something wrong with Annatar, and so why not Celebrimbor? This person appears on the scene with no history (though if he made up one, I'd be interested in what Sauron said )? At least Tom was known to be - exist - and had a track record. What were Annatar's bona fides - what allowed him to get so close to such an important elf?

I think that Celebrimbor 'played dumb,' even to Annatar (who may have suspected that he was suspected) in order to mine as much info from the maia as possible, hoping to turn the Gifty one out before things went sour.
