BugChess2 1.5.2 is out !

[FrancoisK]

Hi all

This version seems to be an improvement over 1.5.1 in blitz at least.
As usual it can be found on Leo's site : http://wbec-ridderkerk.nl/html/download.htm

Thanks to all testers

François

PS: new users, do not forget the "-winboard" parameter to use it in a winboard UI (winboard/Arena/...)

[Graham Banks]

Thanks Francois - I'm looking forward to testing this new version, especially after the significant gains you made last time!

Regards, Graham.

Thanks Graham
Do not expect a big jump (or i would have called it 1.6 ).
In blitz the gain should be around 30 elos. Hope next one will be 1.6
Looking forward to seeing it play for the CCRL !

Cheers

>Do you plan to make hash size adjustable? Of course I could easily accept if you said that it would not have much influence on playing strength.
It is already there since long in my private versions, i just have to take time making the parameter understandable by humans . And as you say, the elo gain is probably very small.

>BTW, here 1.5.1 and 1.5.2 scored the same 65 out of 177 on the Arasan6 test suite (10 secs/position, P4 3GHz)
Thanks for the test I am not surprised that 1.5.2 scored the same as the main improvement of 1.5.2 is a better time control management in games.
