@ notyet, Yes, at the beginning of each chapter an annotated game is presented that features one of the thematic lines for the variation under discussion.  For example in the Baguio Revisited Chapter the Game Korchnoi-Karpov with black playing an early b5 is featured.  After the annotated game is the section 'Looking a Little Deeper" where the theory is explained with branches, and such.

The recurring themes I notice in this book is White pushing d5 at various moments, black playing f5 a la Dutch, or black lashing out with b5.  I guess these are some of the most common ways to unbalance the position in the Nimzo.  Overall, there are some ideas that I'm not so hot on (4.e3 Ne4 and 4.Nf3 Ne4) but the rest I like a lot.  Really I just wanted to get a book that had some new and interesting positions for me to look at and analyze, and this one fit that bill perfectly.  It gets the creative juices flowing!

Here's Palliser's conclusion about the Topalov Gambit:

"5...c5!? offers Black good, active play after both 6 Bg5 and 6 dxe6.  Accepting the gambit with 6 dxc6 is critical and needs more testing, although it is not at all easy for White to develop and consolidate.  Much more critical is 6 dxc5 which fortunately isn't the first move many opponents will probably analyse over the board.  Then 6...Nxd5 leaves Black a little worse and so 6...exd5 may objectively be the best choice.  If that's so, and much does remain to be discovered after 5...c5!?, then the Topalov Gambit sadly isn't really a gambit but just a tricky move order device!"

Think it depends how well these ones sell, life being what it is. If they go OK though then yes I think it may develop into a series.

Thanks Stormcrow!
I'll probably buy it soon. I wonder if this is new series from Everyman and when (if) other boks will follow.

This is a nice, fat book (272 pages) with lots of interesting ideas! As one can see, some chapters are geared towards white, while others for black, but useful for either side, really.  They make no claims about the ultimate soundness of some of these; they are just trying to arm players with some fresh new ideas in order to cause difficult problems to solve for the opponent...most of these lines create very interesting positions, and I'm really looking forward to digging into this one!
