Re: Ethereal & Schooner seems to be "Big Monsters"

Not beta, but alpha or whatever the best score is. This can be a positional evaluation or a hash score. If the best score is very large, the null move search is ignored. Thus, sacrifices are invited. I remember posting something about this a long time ago when Schooner was about 2500-2600. No one w...

Re: Ethereal & Schooner seems to be "Big Monsters"

And now Schooner. The game is for humans for sure very complicated. But Schooner like such things (saw that in other games too, here the perfect example) and it seems the style is very speculative with aggressive knight, rooks and bishop moves.

Re: New engine releases 2020

Oops, embarassing fix just published. Francesca 0.29a has been uploaded to my website (www.silentshark.co.uk). This hopefully fixes a bizarre bug which seemed to kick in on games where 'ponder mode' was on. Nothing else changed, so if you've used 0.29 without ponder, there should be no difference. P...

Re: On-line engine blitz tourney June

Great tourny, thanks, and helped me find a stupid bug.

You are a monster jonkr, still finding so many Elo lying around.
All the "bugs" I found lately lost Elo while fixing them :-(
Yeah, I know the feeling. I've got plenty of bugs, but just not the +50 ELO flavoured ones :-)

Re: New engine releases 2020

Francesca 0.29 is released today, June 1st. You can download from www.silentshark.co.uk Hi, is it possible legacy version is for older CPUs and fran.exe is with bmi2 instructions? (fran.exe here crashes on a core I7 ivy bridge) I think that's right. The version fran.exe is compiled with the /arch:A...

Re: Just found a 55 elo bug in SlowChess 2.1

If anyone else has stories about surprisingly major bugs eventually found in a chess engine, feel free to share here. I continue to find bugs, but as you say sometimes fixing them gives little improvement, which is weird. I had a horrible bug a while back in my SEE, which meant the SEE was pretty r...
