OG 11 Explanation References Guides

by Gouman » Sun Jun 21, 2009 7:23 pm
I'm looking for alternative explanations to those in the the 11th edition official guide.

Can somebody direct me to books comprised of explanations to OG 11 problems.

There is one I'm looking for in particular but, I can't remember the name or the publisher.
