The hands cover a selection of problems, from card combinations, to avoiding loss of trump control, over ruffing, and other problems.
Its not focused only on "safety plays" like how to play A9xx opposite KJxx for one loser.
Overall, I liked most of the problems, and some were devious! :-)
I don't think I got good value for the money because there was lots of wasted space and pages, repeating the hand. The book could have contained 50 - 72 hands in the same space/size. If the price was $6 it would be more reasonable.
Worth reading, if its in the Library.
