Re: Anyone sells Gustav besides Schach Niggemann ?

I never bought Gustav before. So I cannot compare it to anything.
Gustav is a mate solver, like Popeye or ChestUCI.
Gustav is a lot better on some kinds of problems.

Not for you sir. You are 42 cents shy, ignoring our shipping cost.

You can never foresee every possible failure. Tried to write to file? Disk got full or permissions were wrong or file was locked or...

Anyone sells Gustav besides Schach Niggemann ?

They won't sell it to me because it is 49.50 euro and the minimum order is 50 euro. I don't see anything else I want to buy.
Also, the shipping for the CD is $27.50. Seems high to me.

Is there someplace else I can buy it? Or is Schach Niggemann the only distributor?

Re: Opposite Color Bishop Endgames

One should remember that the design goal of engines is in general not to be good at chess, but just to have a high Elo. If worse programs score better in games, it is preferred to make them worse. I have some trouble to understand you, to be good at chess IS to have a high Elo . In the case of oppo...

Re: A fabulous thing about Winboard

In C++ all you have to do is: try { something_that_might_crash(); } catch (...) { // friendly, diagnostic error message goes here. You can get a lot more clever if you know what the likely exceptions are. } My friend Les Fernandez wrote a parser that takes chess contest games and turns them into ful...

Re: Opposite Color Bishop Endgames

But I didn't know until now that coding for opposite color bishops still didn't exist in modern chess engines. In some chess engines. There are engines with intricate bishop code, where opposite colors, bad bishops, bishop pairs, etc. are all taken into account. There are also chess engines that wi...
