Please review this hand

[Sidekick]

I've been at the table about an hour, but there have been quite a few player changes. The table has been rather strange. One round the players seem aggressive and the next round or two they are extremely timid. The only player I have any decent kind of read on is the button and they are slightly loose, but not generally aggressive.

All comments are appreciated. I don't want to give any more information as I don't want to color any of the responses.
