Re: 2016 10th Annual World Computer Rapid Chess Championship

Well, either a moderator can't read or only read the title. I don't know what is wrong with moderation recently, but this kind of ban actions are terrible and damaging.

Re: Floyd 0.8 64-bit Gauntlet for CCRL 40/40

Re: Floyd 0.8 w32 comparative test

A question (if possible) to Mr.van Kervinck: how strong (in blitz 4/40) is the last version of Rookie ? Will be nice to know ! I'm not recently making any changes to Rookie because it has become hard to change. When I made the v3 series I focussed on speed and weight tuning, but now I don't care mu...

Re: Crafty SMP measurement

In chess game playing or analysis, we primarily add cores to search a larger tree at the same time control, not to search the same tree faster: the game conditions or the available time for analysis doesn't change: it is dictated by the environment. We can only add cores and see how the system chang...

What to do when a PV re-search happens to return, after negation, beta-1? How to distinguish between PV and non-PV with the new alpha after?

Floyd 0.8 released

Floyd is a simplistic chess engine I use for study purposes. I have just released revision 0.8 because after some eval modifications it is much stronger than the previous version.

Re: Xboard sluggish on OSX

Today the macports xboard/xquartz combo is relatively snappy again on my main user account. Not great, but much better than it was 1 week ago (or yesterday for that matter): the application is even workable for now. I have not accepted any upgrade or macports update that I'm aware of.

Isn't that a consequenceof the 'auto-raise board' option?
Which menu has that?
