I agree that a perfectly played game should be a draw. The problem is that with current rules, one player must make either several mistakes or one very big mistake to lose. Ideally any mistake should lose, a draw should result only from ideal play which no one should ever be able to achieve. Or at ...

Newer programming languages such as Rust actually provide u128.

To be honest, I think it is somewhat convoluted. It seems the only way to make chess harder for computers is to make it also harder for humans. I've always wondered at the simplicty of Go as compared to chess: The rules (except for some very special situations, I think these are all of them...) - Yo...

Yes. At some point I'll be implementing such enhancements in the move generator, but that will be somewhere down the line

Thanks for the extra tests chrisw. I added them to my perft suite. (I assume the very large chunk is the well-known perftsuite.epd, as I've sampled a few and I already had them all.) All of the extra tests such as "double check", "castling gives check" etc run just fine.

Congrats :) Maybe a suggestion which is used in Rust (and in the Stash engine as well). It can be beneficial to put your header files in an "include" folder, and your source files in an "src" folder; even dividing the src folder into multiple subfolders, where you gather modules that belong together...

Back on the same subject ... In fact Minic has less cache misses and less branch prediction misses than stockfish ... Perft 6 of start pos in 4.7sec, so move gen + copy make at 25Mnps .... probably not the issue It depends on the speed of your CPU. Perft 6 from the starting position runs at 4.4 sec...

I prefer a custom set of artificial positions that test most of the movegen gotchas that can be validated instantly at much lower depths. As said: I ran the entire perftsuite.epd file (in which I've included all the positions on this page: https://www.chessprogramming.org/Perft_Results), and they a...

Hello again :) Thanks for the assistance in the other topic with regard to getting the hash table working. I've now been trying to optimize the memory usage of the entries. Before, an entry looked like this: zobrist_key: u64 leaf_nodes: u64 depth: u8 17 bytes, which Rusts pads to 24 (next multiple o...

Years ago I was looking into other games besides chess. I also tried Arimaa for a time, but ended up not liking it. Too positional, not enough tactics. I love tactical positions with sacrifices that make the position explode and end the game with a bang. Arimaa doesn't give you a lot of tools to mak...
