That Mate in 5 again

Latest Stockfish Dev (2019-09-16, one thread, own compile, no tablebases). It's a monster :mrgreen: Oh well, at least it is getting there, currently failing high for the eleventh time and searching with a reduced depth of 67 plies. Ten hours and counting. rk6/p1r3p1/P3B1Kp/1p2B3/8/8/8/8 w - - Engine...

Re: Analyzing a position Ding-Firouzja wcup19

Don't think there is much going on in the position, not that I can see. Old Ancalagon only gives +0.08 everywhere, this was pre contempt, I believe it had something to do with the side to move bonus but I'm nor sure anymore. Or was it a primitive contempt bonus? But that was the most interesting thi...

Re: Is this position a win for white?

Maybe we can look at the position again, with some improved programming in more than a year and a half and some people with very big machines :)? Maybe see new things as requested also here http://www.talkchess.com/forum3/viewtopic.php?f=2&t=69361&start=70#top The questions still pending for these p...

Re: Pages fail to load??

Good to hear! But if you have more details is there maybe something the administrators could learn, why this site was slowed down in your case? I can imagine that not being https would mean some different behaviour, that might be something to look at perhaps..

Re: Pages fail to load??

I unnderstand from your post in the Help and Suggestions subforum Louis, that it was when visiting the website from your University network?

Re: can Black win this game after 29. Rxb6?! ...

Black still has a plus, but to me looks like White has reasonable chances to draw, in spite of score, after 30... e5 {instead of 30... a5?} 31. a5 exf4 32. gxf4 Kh7 33. f5 {=+} Kh6 34. Rxa6 Kg5 35.
