what happened to scorpio NN in TCEC?

It is also in the participants list in division 4 http://www.chessdom.com/tcec-season-14-lets-get-ready-to-boom/ For some reasons I do not see it in the table now https://tcec.chessdom.com/ I thought that after some X games people decided...

What does your program do in this? fen 4k2r/pb3p2/2p1p2p/1p2q3/B1p5/2Pr1B2/2Q2PPP/R4RK1 w - - 0 1 Provide full search for a five minute run. For extra credit beyond getting the best move, name the (human) players in the position. I do not believe humans played this position. In order to get this po...

Re: Komodo MCTS scales worse with TC than Komodo A/B?

First, I checked that K12.2 AB and K12.2 MCTS behave very similarly in all sorts of variants and phases of the game, so Leela weird behavior in variants and endgames (weaker than regular chess performance) is due mostly to its eval and not to its MCTS search. K MCTS is simply about 100-150 Elo poin...

Re: Is there a tool to ask the computer how it can understand code?

I am the author of movei but I got a lot of help from other people with the non mathematical part of the program and I also started by copying some structures from tscp but not working chess code(and my move generator is clearly different than the move generator of other programs) I do not like to s...

Re: B strategy is the future.

Chess engines using heavily brute force search are not playing chess. They emulate it via search tree. What we need is an engine that knows about chess and chooses those branches and lines That makes sense using a chess knowledge, Like humans are doing it, stockfish and other top programs already d...

I know NO human being playing chess doing brute force. What a nonsense.
Of course in blitz it is not possible but at long time control I try to look at all the options that I have in the next move and all options that the opponent has in reply to my move as part of my thinking.

Re: Question for Engines testers ?

The result depends on the time limit, but in general Komodo does surprisingly well giving material handicaps to weaker engines. I would think that it will take a rather strong modern engine to score 50% at some moderately rapid time control against Komodo at this Exhange odds handicap. Since you sa...
