On Charles, reply to 2. Above. Mine is not rated on CCRL and won’t be because they don’t rate private engines. It has a rating of about 2750 or so at 5 1 on the nightmare.nl server and it gained maybe 150-200 or so in it’s time there because A) it now has a book, B) I implemented last SMP and C) it...

I mean if you get a 64 bits integer telling which squares are attacked you can't see if it is correct. But when you get a list of coordinates you can. Really? It's very simple to display a bit-board in a text window with a normal board representation. something like this: constexpr bb_t Bit(int x) ...

"Board" handles the board and makes/unmakes moves onto it. Board of my engine is not replaceable. Tried once to repair that but got crazy of the errors. So best is to start with a non-bitboard implementation. And if one wants to use bitboards later then one must not change it's interface. Bitboards...

If I set up a position with a black rook missing, and white to move, the incoming messages all have an eval of 592 (advantage engine/white). If I set up the same position but with black to move, all incoming messages have an evaluation of -592 (disadvantage for engine/black). If I reverse this and ...

I've got very strange weights with the E12.52 set, after this I re-tuned with the E12.33 set, now the weights look very similar to the weights I get with my own 4M set. I didn't check performance with self-play yet, but I used these weights during the last blitz tourney. Besides the loss against Cor...

There's a lot of wisdom in waiting. That can indeed be true. My previous computer lasted for 8 years. The reason why I'm now wanting a new computer is because I got into chess programming, and the first version of my engine is nearing completion. After testing it, it needs to be retested again and ...

I never read or post anything in CTF, it's existence doesn't bother me either, so I vote 1

Surprisingly rofChade ended above the two Stockfish derivatives Honey and Belfish and won the tournament. Goldbar was very happy that he managed to get a draw in the last round against Honey, rofChade owes him a beer for this accomplishment. Nightmare unexpectedly lost from CoronavirusChess in a wei...
