The first two volumes in the Harrington series (Strategic Play and The Endgame) cover the entirety of a no-limit Hold’em tournament and are acknowledged by pretty much everyone (except possibly Doyle Brunson) as the bibles of poker strategy.

This, the third, is styled as a companion to the previous two, with 50 poker problems for you to work through taken from real life and online tournaments, and which concentrates mainly on one thing: improving post-flop play.

When should you bet? When should you check? What can you deduce from opponents’ actions?

Answers to all these questions are revealed as you work through the quiz-style book building up a score for a final grade.

The true genius of the book lies in the way Harrington dissects a hand to show you the correct play, even if in that particular instance it doesn’t pay off.
