welcome to my first book:
146574 - 80 ply
after collecting hundreds of books from others I decided to produce one of my own.
with the use of playchess database, cbdedupe and Norman Pollock 40H-PGN program "truncate" I have produced a database of 146.574 games win only. It happen that yesterday has been made pubblic Sicilian Hit 7 and I decided to run a short test (20 games) between this higly acclamate book and mine not yet manually tuned.
A quick test vs itself to produce some evaluation in the virgin lines and set the test vs SH7.
the comp: Intel(R) Core(TM) i7 CPU X 980 @ 3.33GHz 3332 MHz
set: 3 minutes, 128MB optimise as per instructions
With no surprise all the 20 games where "sicilian" the surprise was the results:
games: 146574 vs sicilian hit 7.games - filedropper
Book links:146574 - 80 ply.ctg - filedropper 146574 - 80 ply.ctg - mega
