Instead of a chess tactic, I wanted to let you know that the new January 2013 issue of the Colorado Chess Informant magazine is out, and available for free online.
You can access it here:
http://www.coloradochess.com/informant/January%202013.pdfThe magazine is 52 pages long in PDF format. Fred Spell, the editor, did a great job. The Colorado Chess Community is really fortunate to have Fred, who does a super job.
My "Tactics Time" column appears on page 25.
Grandmaster Alex Fishbein wrote a review of "Tactics Time 1001", the new book by myself and Anthea Carson, which was really amazing.
Chris Peterson wrote a really good article with some ideas on how to improve chess tournaments.
Jeff Baffo has some entertaining game annotations.
Brad Lundstrom wrote a beautiful tribute to Life Master Brian Wall, which is one of the best articles I have ever seen.
Joe Fromme wrote a great article about his trip to Iceland to pay tribute to Bobby Fischer, which I also really enjoyed.
I think you will enjoy the issue.
