I supposed so.

This is fine news. :-)

I expect the worst. :-)

AFAIK one can only analyse the current loaded game. It would also be useful to
analyse all games of a database. And, of course, me and some other computerchess
addicts would also like to see EPD analysis, either with analyse EPD or with
analyse database where the database only contains EPD/FEN-positions.


>3d) Yes (finally!)


I gave up hoping for this, now it really happens! :-)

This would be absolutely great. So far only Shredder and Crafty have that
function included but many more users with 2 PCs or more have and prefer LAN
instead of serial connection.
And using LAN, well, some companies may complain about that follow-up to DOOM.
;-)
Imagine company-wide championships either human-played or different
personalities. :)
No more reason to play that Johnnie-Walker-game. ;-)

OK, when Johan says so...even MCP8 fills 61MB easily on tournament mode on
K6-200 and the King is not much slower.


So

Would it be hard for the programmers to get the physical free RAM and set the
hash automatically to the first value below that size?
