query_posts() show from post 2

Hi

I’m trying to change my theme so the post showing will be difrent depending on what catogory post1 is.

What I want is that it shows post 1-10 if it’s post 1 is not catogory=1. If post 1 is catogory=1 then show post 2-11

in pesudo code

if post(1)!=cat(1)
     Then query_posts(1-10)
else if post(1)=cat(1)
     Then query_posts(2-11)
endif
"The Loop"
