A gift card of mine expired at the end of October, so I decided to spend the $15 or so that were left on a chess book. I figured the shipping and handling would cost at most $5, so the book should cost around $10. Went into a portal to look at the candidate books. It turned out the choice was very limited. Most of the books were well over $20, and I spent a lot of time looking for something sensible. Finally settled on Chernev's The Most Instructive Games of Chess Ever Played, for $9.95. The book arrived yesterday, and it looks like I made the right choice. Anyone else have suggestions for an alternative under $10? Just wondering if I could have picked something better.
