Here's what I've learnt:

* Use CriteriaQueries when you are letting user build queries
dynamically. Actually you have other options now, with Linq to
NHibernate you can do this with Specification Design Pattern.
* Use named queries for best performance. They will be initialized by
NHibernate. You can use them for frequent querying. You will use
Hibernate Query Language for this.
* Use Linq to NHibernate if you prefer type-safe query code. You can
also use L2Nh to implement the Specification Design Pattern.

I'm not sure when to use QueryOver. I keep forgetting which means it
is not that interesting to me :-)
Good luck!

P.S. For more about Specifications you can see this post:
