A pincer  

As a novice, I only feel comfortable making a pincer move when the group that my opponent is attacking is fairly strong, as this diagram shows. Otherwise I prefer to make an extension or attachment.

I took the liberty of rearranging your stones a little, to make it look more conventional.

Note that here is actually a very bad move; this move hardly improves on passing because the stone is so weak.

Going back to the first diagram, remember that White also has a one-stone group left. It will be almost automatic that either the corner or the pincer stone becomes strong while White is settling her own stone.
