domain AceMr.com and another

[estibot.com]

I grabbed a couple of short Ace themed .com's:

AceMr.com - maybe a good poker themed site?

AceSF.com - Good domain name for a Science Fiction or San Francisco site?

Any other meanings for SF come to mind?

Please appraise: Do you see inherent value in the names, or just potentially after some development, or not at all?

I like them because they are short, and short .coms are in, well, short supply. I think they are also brandable.

Thanks for any input!
