PostSubject: Is there a way to convert old .MVS opening books?   Is there a way to convert old .MVS opening books? EmptyFri Apr 30, 2021 12:31 am

Hello everyone my first topic here, recently I've been searching the web for old gambit books. Found few with .MVS extension (books used by Chess tiger and early versions of Rebel)
My question is if there is a way to convert this books into newer formats? I've heard that earlier Fritz and Chessbase versions were able to but unfortunately I only have the newest Fritz17 version which does not support those old .MVS opening book formats
Any help is appreciated

I think I somewhere have an old tool that converts *.MVS to PGN or RBM. Will look for it.

Found 3 things -

1. util mvs2rbm usage: mvs2rbm wolga wolga

You get output like this:

Code:
D2D4 G8F6 C2C4 C7C5 D4D5 B7B5 C4B5 A7A6 B5A6 C8A6 B1C3 D7D6 G1F3 G7G6 E2E4 A6F1 E1F1 F8G7 G2G3 E8G8 F1G2 B8D7 H1E1 D8A5 H2H3 F8B8 E4E5 D6E5 F3E5 D7E5 E1E5 B8B7 D1F3 F6E8 E5E2 E8D6 C3E4-D6F5 C1D2 A5B5 D2C3 F5D4 C3D4 C5D4
D2D4 G8F6 C2C4 C7C5 D4D5 B7B5 C4B5 A7A6 B5A6 C8A6 B1C3 D7D6 G1F3 G7G6 E2E4 A6F1 E1F1 F8G7 G2G3 E8G8 F1G2 B8D7 H1E1 D8A5 H2H3 F8B8 E4E5 D6E5 F3E5 D7E5 E1E5 B8B7 D1F3 F6E8 E5E2 E8D6 C3E4-D6E4-F3E4 A5A6 C1G5 G7B2 A1D1
D2D4 G8F6 C2C4 C7C5 D4D5 B7B5 C4B5 A7A6 B5A6 C8A6 B1C3 D7D6 G1F3 G7G6 E2E4 A6F1 E1F1 F8G7 G2G3 E8G8 F1G2 B8D7 H1E1 D8A5 H2H3 F8B8 E4E5 D6E5 F3E5 D7E5 E1E5 B8B7 D5D6-E7D6 D1D6 A8C8 C3D5 F6D5 D6D5 A5A6 E5E4 C5C4

Each move is 5 bytes, the fifth byte decides to play a move (space) or not (-). I know there is software that uses this format to create a PGN or Book.

2. mainbook.pgn and tourbook.pgn.  These are the last Noomen books from 2000-2002 which I in 2016 (or so) converted to Polyglot. Also here counts moves marked with { - } don't play. But it is save to create a polyglot book from it since the first { - } case decides the the result, a white move with { - } the result is 0-1, a black move with { - } gets 1-0, when there are no { - } cases the result is a draw. Polyglot --Makebook relies on the result of games.

3. util obk2rbm usage: obk2rbm sharp sharp

OBK is the format used by many old engines, the most popular one is Chessmaster. Not sure if it works for Chessmaster books but it works with sharp.obk, a Noomen book.

RBM to PGN conversion is somewhere hidden in an old ProTools util from 10-15 years ago. I will make it available soon. Stay tuned.

http://rebel13.nl/dl.html?file=dl/protools.7z

. Start ProDeo.exe
. Press [F4]
. Select RBM to PGN & EPD
. Pick a RBM file

Output in the PGN and EPD folder.

It's very old code, output looks good, but no guarantees.
