Query: A Keeper

I'm a Life-Master. I currently teach chess full-time to make my living. All the endings you need to know are in here, maybe a few you don't. Most players do not want to take the time and trouble to study endings, its just too much work. But if you really want to get better, there is no way around it. I could offer many criticisms of this book, but I won't. They are mostly VERY minor. Bottom line? If you are under 2100, or if you have ever blown an ending, this book belongs on your chess bookshelf. Or better yet, don't buy it. Don't study it. Then put a sign on your back. I'll bribe someone to play you at the next tournament. Thanks.
