input with options: Title: Junk Review: The plastic buffing disc broke off very suddenly during use and caused the large hex mounting bolt underneath to drive straight into the side of my vehicle, scratching the paint down to the metal before I could pull it away. This $25 buffer is going to cost me a few hundred dollars in repairs. Interdynamics no longer appears to list buffers on their website, so perhaps buffers weren't their thing.

input with options: Title: An Error-Filled Classic Requiring Hard Work Review: Apparently, a lot of players weaker than I have found this book extremely helpful. I am a Class "A" player (1800+), and I found this book slow, tough going. It is quite helpful in teaching how to attack, but I personally found it difficult to see the forest for the trees: there are long variations in many positions, and often there are errors (duly pointed out by editor John Nunn). When the errors contradict the author's point, what are we to think? And even when they don't, the wealth of detail can often lead you away from the principles Vukovic is trying to illustrate. So, in my opinion, this is a good book, but to use it, one must:1- work hard at going through all the variations, and then try to correlate them with the points the author is trying to make;2- be willing to make allowances for the mistakes and errors.
