Every Day Errors in Checker Play by Baron Gossett Euler PhD, freely downloadable on http://www.bgonline.org/book.pdf. From the introduction:
In this book we examine the everyday stuff — moves where Black bleeds equity without even realizing it, game after game, drop by precious (cube) drop until eventually it causes his game to fall short of the beautiful ideal of simple play. The shocking truth is: This is why we lose! […] We self-destruct over the everyday stuff: positions that seem the same but really aren’t the same, although we insist upon treating them in the usual way.
