Funny you should ask...
you're right, there is definately a lack of tournament info available. Wong is still the standard, although in many ways, no longer does the trick. Tourney pros have been revising Wong since the late 1980's, when Anthony Curtis, Blair Rodman, Russ Hamilton, Fred David, and the other guys on the Alan Brown team would sit up late into the night coming up with more & more adaptations to the basic strategy he offers. In the 21st century, especially against better players (And there are a lot more of them now than there were 20 years ago), Wong alone simply isn't enough.
That's one of the reasons why I've been writing 'Hollywood Blackjack: ATS' that presents the end-all, be-all Advanced Tournament Strategy for facing the demands of modern day tourneys. My first book, 'Hollywood Blackjack' is already completed & going through the editing process with my publisher (RGE) for a Spring release date, and breaks down card counting, cash tables, and some pretty crazy stories from my days in the trenches... & now i'm over half way through the companion piece, 'ATS' which is 100% tourney strategy. it should be out later this year.
Not only do i reveal a lot of the secret tricks, traps, and correlations you can make that Wong doesn't cover, but that have been in use for over a decade now by tourney pros, i also reveal a completely new strategy that shows how to set a specific level of aggression (the Aggression Index) based on your Profiling of the varying skill levels of players at the table. Wong's greatest shortcoming is that the presupposition behind all of his theories is that most of your opponents will generally be ignorant to solid tourney strategy; which, to be fair, was true 20 years ago. Now, however, that is true less and less of the time, especially when vying for prize pools that enter into the hundreds of thousands of dollars, or the majority of TV shows where tourney pros are a dime a dozen. That's why the cornerstone of 'ATS' rests on a reflexive strategy that, much like in poker, allows you to adjust in real-time to the particular demands of the game, using much more aggressive strategies than Wong would find acceptable -- but are often necessary in today's tourney climate.
OK, i'll stop shilling my book now... but hey, you DID ask! And to be quite honest, every day i spend working on this only gets me more excited, i think you guys are gonna like what you see once its all said and done...
