There are three books in the Harrington on Hold 'em series. Volume 2 discusses late game play in tournaments where the blinds are high and often times a player's only choice is to go all in or fold. These books are absolute must-reads for any beginning or intermediate no limit Texas hold 'em tournament player.
Harrington is a World Series of Poker main event winner. He's known as "Action Dan", a joke which indicates that he is usually seen as a dry, boring, and tight poker player, but anyone who reads these books is going to have a very strong foundation as a well rounded tournament poker player.
This book has sections on different types of bets such as continuation and probe bets, bluffing and semi-bluffing, squeezing (going all in after an opponent has raised and there is a a caller), playing with varying stack sizes (short, regular, or deep stacked), how to play shorthanded and heads up.
The examples and quizzes are back again, only now there are more because late game situations are so critical to maximize profit. They are great, as usual. If you want more examples, there's a third volume -- a workbook -- which covers the scope of both Volume 1 and Volume 2 of Harrington on Hold 'em.
You need the first book along with this book to construct a comprehensive tournament strategy. Most serious tournament players will own both, so it's good to have them and read them if just to know your opponents better, although at the same time you will develop your own winning strategy based on Harrington's analysis and examples. This is definitely a book every tournament player needs in their library.
