Re: FEN and 3rd repetition rule. No information?

Does anybody have any hope of having a #1 XBoard engine? Fairy-Stockfish supports XBoard protocol, right? It should not be far from #1. I can make a #1 XBoard engine for you in 15 minutes or so. :lol: You probably also think that Windows must be a lot better than Linux? Because most commercial soft...

Re: FEN and 3rd repetition rule. No information?

But Crafty topped as a best 50 engine, and from the other 49 that are above it, less than 4% are Winboard/Xboard. This is a trend that shows how being UCI is a treat that most top engines have in common, and that there have been several engines that have passed Crafty over the years, written from s...

Re: FEN and 3rd repetition rule. No information?

Thanks Chrisw! I think I´ll use xboard protocol but sounds very nice that. My concern is that when I´ll use perft results this will be take in account. It seems not.... at least not for the moment. I would not use Xboard, UCI is so much better and the documentation way more concise, most 'sensible'...

Re: FEN and 3rd repetition rule. No information?

What does the protocol have to do with this? I looked at UCI extensively. I have used xboard since 1994. I still find myself preferring xboard. UCI interfaces usurp too much engine control. A GUI is a "user interface". Not an intrinsic part of the chess playing engine. I don't want the GUI choosing ...

Re: FEN and 3rd repetition rule. No information?

Hi people! With my "stay at home" cause coronavirus, I´m starting a new code for Soberango. When I did the moves generator for my first version of Soberango, I did not planed it to be able to detect 3rd repetition rule so it seems I did not thought in this before. As far as I understand, the FEN no...

Re: When will the chess programmers write an engine that plans ?

While we wait, a position Berliner opined about: r1bq1rk1/pp2ppbp/2n3p1/2p5/2BPP3/2P1B3/P3NPPP/R2QK2R w KQ - He insisted White must play Rc1 here. Engines at low depth go for 0-0. It looks like 0-0 is by far the most popular GM move too, but I don't have access to a big database. This is interestin...

Re: When will the chess programmers write an engine that plans ?

The book is called The System, and he gives numeric points to various features of chess. He gave a valiant exposition of why d4 is best (not sure if he was right or wrong about it, but it is pretty good at any rate). The whole book is about how to compute chess numerically. If you look at his corre...

Re: When will the chess programmers write an engine that plans ?

Chess is NOT all about tactics. In most positions there is absolutely no tactics. Chess is nothing but tactics. Just because one position has a quiet move at the root, says nothing about what happens deeper into the tree. Ever won a game without either winning material or mating your opponent? Posi...

Re: When will the chess programmers write an engine that plans ?

Here's a question: Suppose you are in the market for building a house. You have a pretty good idea of what you want. You find a guy that listens to you, and then builds exactly what you asked for. No blueprints, no drawings, he just builds it and ends up with a result you are happy with. OR, you fin...

Re: Engine programming

Normally you should start with the programming language you know best. Unless it is COBOL or an interpreted language. At that point, you should look at the languages you know, and which one you would really like to get familiar with, since chess programming is going to force you to use more than bas...
