Hi folks,

been working and testing the next version of GNU Chess, and after all of 
Lukas's hard work on threading it is time to think about shipping.

I have just committed a change to use GNU standard command line options 
"--help" and "--version".

The NEW syntax for GNU Chess is something like;

- ------
$ ./gnuchess --help
GNU Chess 5.06
 Usage: ./gnuchess [OPTION]
  -h, --help          display this help and exit
  -v, --version       display version information and exit
  -x, --xboard       start in engine mode
  -p, --post         start up showing thinking
  -s size, --hashsize=size   specify hashtable size in slots
  Options xboard and post are accepted without leading dashes
  for backward compatibility
Report bugs to <address@hidden>.   
- ------

Essential for 5.06

The only "essential" change still needed for release of GNU Chess 5.06 AFAIK is 
to fix the "hint" command (it was always broke apparently, but now it is more 
broke in that it doesn't produce a hint ever).

Desirable for 5.06

Performance patches from Anil.
Avoid unneeded CPU usage when game is ENDED
Fix "<<" in SCID analysis mode (must check what command SCID is issuing).

Can be left till a later release

Improved PGN parser
Performance patches from Ulf
(Possibly) ensure eval function is symmetrical (returns same score from both 
points of view).
(Possibly) King safety in end game issue
(Possibly) Rook pawn capturing issue
Improved handling of some "known draws" KBRPvK, KPvP
Stop search at 50 move draw correctly.

If you want to work on any of the essential or desirable issues for 5.06, let 
me know.
