I was hoping for 18. Rc2 as I found Re6! Yes, I think 18. Rc2 leads to a "black to move and mate in X" position :) 18. Rcc1 is the only move that still holds the draw (except that one misstep and I'm toast, let's see if I don't trip.) We can finally show how a position where white is lost looks lik...

It seems Komdo 13.2.5 is able to convert this endgame against Lc0 and SF 10 but not SF Dev. Game duration 1 hour and 50 minutes. Lc0 2-Core | Komodo 6-Core | Ponder on. [Event "?"] [Site "i7-5960X 4.5GHz"] [Date "2019.11.07"] [Round "?"] [White "lc0"] [Black "komodo-13.2.5-64bit-bmi2"] [Result "0-1...

Well now I feel better about springing for the whole 64gb.

Especially if you're doing deep deep analysis. People who know more than me, say Hash works best if there is some hash pressure, meaning that it gets at least 50-70% full. I'm not an expert, so I take their word.

Just noticed that Sedat published a new version of his excellent Perfect series. Supported are all common file types, from Arena to Polyglot. I have always found these to be of highest quality and wanted to thank Sedat for his continued contribution to our hobby. (still missing his friendly online ...

Ok, one more question, then. Does Stockfish have to have hash tables in powers of 2 anymore? Or can I use, say, 12gb of ram for hash? (Or 48?) I know there was a commit last year that dealt with something related to this, but my understanding (despite not being a NOOB) is limited of such matters. Y...

based on what I see, I no reason not to use SF contempt scoring in analysis, but I understand people have their own reasons and that's fine, it is certainly not my way or the highway ;>) - also , note - that SF contempt code is symmetrical ... Are you sure, Mike? To me it looks like Contempt breaks...

The only place where it matters, both in game play and analysis, is when the score is very close to zero after a good, long think. E.g. Well under a pawn. Well the good news is when the score get close to zero with a deep long think, , contempt also gets very close to 0 info depth 42 seldepth 43 mu...

https://company.playmagnus.com/play-magnus It seems that magnus at age 5 is simply the random mover and I believe that magnus carlsen even at age 5 played better than it. I also tried the application at older age and I believe magnus was stronger than the playing strength they give him also at late...

A simple analysis on a simple position with contempt off and on in Sf code, contempt is calculated for both MG and EG and then blended together based on the position, the contempt value shown below have been adjusted to reflect centipawn values ( in the code I added) r2r1n2/pp2bk2/2p1p2p/3q4/3PN1QP/...
