Released Bremboce 0.6 Java winboard engine

[ogam]

After 7 year from the last release I release a new version of my winboard chess engine Bremboce. I've rewritten the engine in Java!!!
The jar file is downloadable from here:

Features

- Written in Java
- Array board coding
- Negamax search with capture quiescence
- Simple internal opening book
- Recognize: 3 moves repetition, 50 moves rule, draw for insufficient material to mate
- Winboard protocol 2 compatible
- Can load fen positions

Changes from previous version

- Rewritten in Java from version 0.4 that was written in C
- Removed null move, hash tables and the external opening book
- Fixed a bug in evaluating checkmate positions
- Fixed a bug in evaluating king position in the end game
- Fixed a bug with the level command from winboard
- Added a simple internal opening book just to diversify the games
- Added the recognition of draws for insufficient material to mate

Hi Ciro!

I've seen the test on yuour site, it's a very good result considering that the egnine has been rewritten in Java that is slower than C of the version 0.4. Null moves and hash tables that I've removed were probably buggy and a few bug fix have done the rest. Have you used the jar file for the test?
Jim Ablett has kindly compiled the jar file with Excelsior Jet to have x86 native code but on my pc Athlon 64 X2 seems slower than the one in Java byte code.
Thank you!

Do you want to test this one with my laptop (Vista 64bit)?
