Hello Michael, Just curious, how is the new version of Romi coming along? It is eagerly awaited! :D -best wishes, Carl There comes a point in someone's life as they get older if they are honest that they must admit that they are just not able to do what they were once able to do. I think that I rea...

Here is analysis of Fat Fritz 1.1 https://share.chessbase.com/SharedGames/game/?p=MK537QVcmtW2D6fVZhycy5GPKiAXDiXy72BKqOScvm3kbnjaejRBOjAc4yJEdHuS Looked. The initial sacrifice was not the best, obviously. But, nonetheless it was very interesting play by a 2400 CCRL engine. Both engines did find qu...

Has anyone tried running RomiChess under Banksia? It was in a knockout tournament I ran the other day using the console app not the GUI and ... it won :D I'm not a winboard expert so it may be something silly going on that I don't follow. First of all it apparently forced Ethereal 11 and Ethereal 1...

What I do in RomiChess is generate all the bitboards first without spinning them into a move list. That checks for legality since Romi uses pseudo legal move generation. Next I play the hash move and the check for validity is as simple as checking the bit in the bitboard for the piece. Romi does not...

Sounds inefficient because of all the moves in the hash that do not exist at any given time. I think that two history tables, one of long period and one of short period, might be a good idea.

Looks like a computer generated image. It probably does not even exist. My first impression is it is some kind of scam. But, who knows.

It is able to be compiled without error or warning. It is not a chess engine yet. All it can do right now is make a legal list of moves with material only scores (of course all scores are zero) in the original position. Since this is a new thread it works by generating one move at a time and then ca...

Your questions at the top. Hash table is the problem. 1, 2 or more threads can store and read the same position. That's called a race condition. If you synchronize there it becomes a huge bottleneck. There are other things that need to be read and written by different threads at the same time. Pawn...

Please tell, how does one achieve good move ordering without a list of moves to order? If you have a hash table hit with hash move, but insufficient depth draft, you don't need to generate moves because it will probably (90% - 95%) be a beta cut-off. I just verify the complete move legality of the ...

I create a move priority queue on each node if it doesn't stand pat. On every node of the search tree? Do you have really huge standpat margins lower in the tree? How can queen sacrifices ever be seen? A priority queue can mean many things. I assume that you generate pawns_capture_queens first and ...
