Interesting booklet on card counting, dealing with published methods. A very good (and clever) effect by Scarne is the highlight. The booklet explains the casting out 13, 10 (not well), some effects and various ideas, and a forgotten method from 1905 (by Satya Ranjan Roy) which allows to identify the missing card with just one pass. The method is interesting, but not terribly simple.
The effects are mostly intellectual, as most of Fulves', but the booklet is a good collection of methods on this principle.
