"a killer chess opening repertoire" by summerscale. anyone know if there is an equivalent for black?
You'll need two books. Choose an opening against 1.d4 and one against 1.e4, and learn both. You can't choose what your opponent plays as black!
And it also depends on whether you want to be aggressive or solid as black. A solid repertoire example would be something like the universal c6, meaning the Caro-Kann against e4 and the Slav against d4. A more aggresive handling might be d5 against both d4 and e4, with the intention of accepting the queen's gambit against d4+c4 and maybe playing the Qd6 Scandinavian against e4.
Perhaps the most interesting book in that vein is GM Nigel Davies' Gambiteer II: A hard-hitting chess opening repertoire for Black (2007) which focuses on the Ruy Lopez Jaenisch/Schliemann and QGD Albin Countergambit. There is also GM Lev Alburt, GM Roman Dzindzichashvili and Eugene Perelshteyn's Chess Openings for Black, Explained: A Complete Repertoire (2009).
IM Gary Lane also has a book Ideas Behind Modern Chess Openings: Black (2005) with a repertoire built around the QGD Chigorin and Scandinavian. Other recent books in this genre include Jouni Yrjola and Jussi Tella's An Explosive Chess Opening Repertoire for Black (2002), IM Christoph Wisnewski's Play 1...Nc6!: A complete chess opening repertoire for Black (2007) and IM Chris Baker's Dynamic Black Opening Repertoire (2004).
For what it's worth, long ago I bought "An Explosive Chess Opening Repertoire for Black" by Yrjola and Tella a GM and IM pair. They base it around 1...d6 vs anything. Never went though it, it's sat on my shelf, like I said for what it's wroth :)
Not to mention all the chess videos in Foxy and Roman's Lab series (almost 100 volumes for each set), as well as the Shirov's Best Games in <insert opening here> DVDs that feature his favorite openings using his own games to illustrate them.
And you thought that the video material here in chess.com was overwhelming?
I don't have "Explosive," but Yrjola did a very good job explaining the general ideas behind various lines in his Sicilian Classical book I thought. Chris Baker's white repertoire book had some interesting choices of openings for players looking to attack.
This is just my opinion, but I think in general, books are more useful and enlightening than videos at this point. Most videos seem to be just random thoughts rather than well prepared materials.
In chess, "repertoire systems" are usually just simplistic attempts to avoid learning openings by using a "one-size-fits-all" approach.
It is far better to learn the basics, including pawn structures, and not worry so much about openings. Every player has a different style and different tastes, and as they progress will learn which openings fit them best. They will then develop their own "repertoire" tailored to themselves, and constantly adjust and update it as they improve and learn.
It is true that this approach will cause you to lose some games along the way as you learn and improve, but it leads you toward a repertoire that is your own, and that is the only one you will truly be comfortable with over time.
The presentation is the key to chess videos. As long as you can follow and understand the instructor, it does the job.
Some people prefer books. Others learn faster/better with audio-video instruction.
Finally, you can probably go through more openings watching chess videos than reading books like Fundamental Chess Openings. When you've found the opening that you would like to focus on for the year, you can immerse in good books that focus on it.
