Also titled The Gentlemen's Hand-book of Poker, it is an excellent introduction to the game of poker. It not only covers the rules and some advice on how to play, but it also has a short chapter on cheating, a decent chapter on probabilities, and ends with a number of fun poker stories.
The chapter on probabilities corrects some of what Steinmetz wrote in The Gaming Table Volume 2. The book ends with an anecdote about the compiler himself.
