Re: CMH question
One good way of telling about CMH is what Lucas said: it is basically local history table. The other way goes as follows: first you notice that certain moves tend to be refuted by the exact same move, so you create a table indexed by coordinates of a refuted move, save the refutation there and upon ...

Re: stockfish 10 vs. Mephisto III S Glasgow
many programmers often speak out : why should I put knowledge into my programs when throwing knowledge out gives more ELO Encoding human knowledge in the engine is the polar opposite of imbuing engine with chess knowledge.

Re: stockfish 10 vs. Mephisto III S Glasgow
Ugly is to burn resources for beeing lazy in programming. No. Ugly is to write expert system with layer upon layer of code to handle corner cases, only to be asked "but why placing a rook on a closed file when there is enemy queen on the same file plus a chance for a pawn break is considered less i...

Re: stockfish 10 vs. Mephisto III S Glasgow
Also, misdefining intelligence as adherence to some restriction pulled out from a hat is, well, not very intelligent. I could probably write na engine playing something resembling 1800 Elo chess in 1000 nodes searches, but its code would be ugly beyond measure. Thousands lines of code detecting tact...

Re: For those that like to toy with Ethereal...
Recently I noticed that (eval - beta) part of such formulas - I used 3 + depth / 4 += std::min(3, (eval - beta) / 200) - increases time to solution in certain tactial positions, where you need to sacrifice a piece and play a couple of quiet moves material down.
