So whats' the fuzz about new engine releases ? 50 points rating improvement isnt that much, it can also be achieved with better books, hardware and so on. But yes you can use all together as well obviously if you're really fanatic.. And better engines -like Houdini3-certainly help me to improve my opening books. So now eagerly waiting for the Komodo5-mp release; end 2013 maybe ?? :)
(will they catch up with Houdini ?)
And when i get some more time i'll see if i can compare my books with the strong Hiarcs14 book, which is in Chessbase (.ctg) format. First step is to compare the 'Perfect' with the Hiarcs14 book, if Hiarcs also is about 50 points better then i will conclude my CP book is equally good as the Hiarcs book. But maybe later i'll see if i can make a .ctg book myself.
