The NBSC Openings

NBSC = No Black Short Castling:
1. Na3 Nh6 2. Nb1 Rg8 3. Nc3 Rh8 4. Nb1 Ng8
was added to all openings. So, Black is not allowed to castle short anymore. This gives
a measureable advantage to white, so the openings can be used for Armageddon rescoring.
But it is also possible, to use these openings with regular chess with classcial scoring
system.

There are 3 pgn/epd opening sets in this download-package:

NBSC_Noomen_3mvs: Built from the Noomen 3mvs opening set (deleted double endpositions and
opening-lines, which are not good for computerchess IMHO (Dutch, King's gambit etc). 
250 lines remaining.

NBSC_V2_4mvs: 12910 lines. Out of the Megabase 2020. All endpositions calculated by 
KomodoDragon 1.0 (Quadcore, 15''/move)
All endpositions in an eval interval of [-0.29/+0.49] (before the NBSC-line was added,
of course).

NBSC_V2_6mvs: 46582 lines. Out of the Megabase 2020. All endpositions calculated by 
KomodoDragon 1.0 (Quadcore, 15''/move)
All endpositions in an eval interval of [-0.29/+0.49] (before the NBSC-line was added,
of course).

I recommend to use the smallest of the 3 opening sets, which is big enough for your engine
play or testing. 

The Book-folder contains openings-books for FritzGUI, ArenaGUI and polylgot-book format
(the ShredderGUI has a serious bug in its opening-book using: It does not recognize, that
the 2 move sequence of the rook (from h8 to g8 and back to h8) makes the short castling
for black illegal. So, an opening-book built from NBSC-lines will not work in the ShredderGUI)
