You're asking if these books are outdated. My simple answer is no; nothing you can read about poker can possibly be outdated.

I've seen a few posts recently saying that SS is obsolete or that this idea or that idea is outdated. To me, this seems ridiculous.

Sure, there are new styles and new ideas, many of which have been brought on by the Internet and TV revolution that poker has seen recently. But here's the important thing to remember: not everyone plays (or thinks about) poker the same way. ANYTHING you can read that might give you some insights to how other play the game -- or just as importantly, insights to how others think YOU are playing the game -- is worth your time, and you should consume it like food, water, or air if you are a poker player.

As for HOH specifically, I recommend it for anyone. Many of the ideas in the books are timeless (ex: in general, play a smaller range of hands when the blinds are low compared to when the blinds are huge; always know where you stand in relation to others [inflection points: M and Q {if you don't know what M and Q are, read the books}]; pay attention to your table image as well as that of others; don't sell yourself short when it comes to making a deal).

These ideas, and many others, are extremely well illustrated through Harrington's "problems," where readers must put themselves in situations and determine the "correct" way to act in those unique circumstances. Here's the shocker: You and I might not agree with what Harrington says are the "right" moves! Of course we won't! But the value we gain in understanding different ways of thinking about the same situations is unsurpassed in poker.

Read the books if you haven't. You'll be learning poker for the rest of your life, and this little timeslice is well worth the ticks on our clock.
