Convert .obk books to .abk books?

[David Dahlem]

Is there an easy way to convert Chessmaster .obk opening books to the Arena .abk format?

Thanks for any suggestions.

There is an OBK2PGN utility, and then the PGN can be imported into ABK format from within Arena.

I am not aware of a utility that converts directly to ABK format.

On a related topic, does someone know if there is a description of the abk format? I am considering supporting it natively inside my engine...

Thanks for the info and link. Looks ideal for a few books but a lot of work for many books, which is what i had in mind. i want to convert the CM Grandmaster books to Arena books. And so far i have 68 Grandmaster .obk books.

OK,i tested OBK2PGN and it works fine. All the games in the output pgn are in this format -

[Event "?"]
[Site "?"]
[Date "????.??.??"]
[Round "-"]
[White "?"]
[Black "?"]
[Result "1/2-1/2"]
1. e4!! e5!! 2. Nc3! Nc6!! 3. f4! exf4!! 4. Nf3!! g5!! 5. Bc4!! Bg7? 6. O-O!!
d6? 7. d4!! h6? 8. Ne2!! Na5? 9. Bd3!! d5? 10. Qe1!! dxe4? 11. Bxe4!! c6? 12.
Bd3!! Ne7? 13. b4!! g4? 14. Ne5!! Bxe5? 15. dxe5!! f3? 16. gxf3!! gxf3? 17.
Rxf3!! Bg4? 18. Rg3!! Bxe2? 19. Bxe2!! Nc4? 20. Qc3!!

Now i must learn how to make quality Arena books from this type of pgn.

Any hints from Arena book experts?

Hi Julien,

Here is an 'abk to pgn' conversion tool with src which may be of some help to you.

After checking the Arena help file, i'm not sure it's possible to create suitable .abk books from the pgn files created by OBK2PGN. All the games are scored as draws (1/2-1/2) and Arena uses win/loss percentage to determine which moves will be played (although drawn games can be imported).

Any ideas?

Use a strong engine to evaluate each of the terminal positions, >+.20 gets a 1-0, <-.20 gets a 0-1, and you get a 1/2 in-between.

You could make a script to automatize the process.

Yes, i already thought of that, but it would take much too long.
