I delivered a webcast for the PASS DBA Virtual Chapter yesterday. It was called Tips & Tricks for Writing Better Queries. I really appreciated everyone who made the time to attend. I hope you found it to be time well spent.
As promised, here is a copy of the slide deck and demonstration code I used during the session. Please let me know if you have any questions.
The presentation was recorded and should be available on the PASS web site within a few days.
