I don't need you getting any better. Dan Harrington's grasp of the game is remarkable. I learned a great deal from his tournament series, even more from his cash games books, and I learned just as much from this one.
I've only finished the first half so far, but Harrington's focus in this book seems to be the most efficient use of online tools. He briefly touches on some basics of poker, the differences between live and online, and then he delves into the world of the database.
His treatment of HUD statistics is very worthwhile for an amateur. I, like many, have Pokertracker and I like to fiddle around with the database a bit and try to get a read on my opponents. But Harrington specifically describes a number of useful statistics that can be utilized to take advantage of patterns in your opponents' pre and postflop tendencies. After adapting my HUD to Harrington's suggestions I have made a number of strong plays that I wouldn't have thought to make otherwise.
He also does a good job of correlating opponents' HUD statistics to their hand ranges and distributions. Reading Harrington 6max online really solidified a number of ideas relating to playing against hand-ranges instead of always having to worry about if he had that K or not.
He gives some really excellent suggestions on note-taking. I went from a haphazard assortment of random notes to a clean system organized by street. He also helped me discern some of the more important information to take note of. There was even a part he wrote just for me that said I shouldn't cuss out my opponents in the note box.
I highly recommend this book to any online player who isn't my opponent. Some of the ideas might be pretty basic to some of the seasoned online pros, but Harrington really laid down a comprehensive baseline from which to knowledgeably examine many of my unrecognized leaks. Seriously, I was just sitting there with VPIP, PFR, and AFQ%. I didn't even really know what the last one meant except that it was somehow related to aggression.
Also, the book stands up very well to getting soaking wet in a rainstorm. The cover is a little soggy but it's still perfectly readable. If it rains enough I'm going to see if the book may even counteract the effects of fire. It's just that good. I'm surprised the Shamwow guy isn't in here.
