NL50 How should I play AA?

[voxx]

I've just sat at the table and it's my second hand, I've not played with any of the players before so I have no read.

I'm new to NL50 having just moved up and I wondered what other peoples thoughts are about how this hand should be played. I've reviewed it myself and have my own views which I'll post later.
