Re: Poll: How Many "Weights" Needed To Play "Known" Chess Very Well?

People can recite 30000 numbers of pi from memory so it wouldn't be out of reach for some people to just memorize the weights and apply them to positions. Someone did 100K digits. There is a difference, though, between having nearly photographic memory and knowing the meaning of the thing memorized...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

1. g4 d5 2. g5 e5 3. d4 exd4 4. Nf3 c5 5. Bg2 Ne7 Still following Stockfish-dev's main line, with a current evaluation of -1.38 (though only at depth 50). Still waiting for something other than a Stockfish move! I think most engines would pick this line. It seems very likely that the whole line is ...

Re: Scandinavian Defense (3...Qd6)

All of the positions from Graham's Scandinavian list (including interior nodes) are quite playable with no position having a score as large as 60 centipawns in absolute value, so quite fair. rnb1kb1r/pp2pp1p/1qp2np1/8/3P4/N4N2/PPP2PPP/R1BQKB1R w KQkq - acd 39; acs 469; bm Nc4; ce 57; pm Nc4; pv Nc4 ...

Re: Ryzen problems - AGAIN!

Well the problem is already well-known: https://bugzilla.kernel.org/show_bug.cgi?id=196683 Basically what it takes to be safe is to either use a crippled kernel or a crippled BIOS, which disables C-STATES and turbo boost. What really frustrates me is that for stuff like CPUs I would assume them to ...

Re: Poll: How Many "Weights" Needed To Play "Known" Chess Very Well?

Suppose it were 10,000 weights needed. Humans would have no hope to comprehend that clearly. We do well up to 7 distinct items, on average. After that, we start to degrade. We can deal with bigger clumps of things by splitting into parts (especially related parts). But past a certain point, we start...

Re: Understanding and Pushing the Limits of the Elo Rating Algorithm

A while ago, Kaggle had a contest for improved game outcome prediction algorithms.
Uri did pretty well in the contest, if I remember correctly.

Re: There Might Exist Simple Rules For TT replacement

{snip} From a theoretical perspective I think this is wrong. e.g. if a mate in 50 is on the board and I insert into the TT the major sub-trees leading to it, the engine should have little problem finding it. {snip} The question is, how did the mate in 50 get into the hash table in the first place? ...

Re: TR 3

I would never do that, but I think it is legal in Washington and Colorado. I guess you have to have some kind of permit, though. It would probably be a much bigger deal in other places. Looks like it's legal in more places than I thought: https://disa.com/map-of-marijuana-legality-by-state I don't t...

Re: TR 3

With all those memory channels, I was thinking of putting in 4 of these in it: https://www.nvidia.com/en-us/geforce/graphics-cards/rtx-2080-super/ Of course, just those four cards will pull a full kilowatt. So a big power supply is a must. Not to mention, I will eventually want a couple hundred TB ...
