Re: Rabid Queen only

Probably was a bug in futility pruning. Congrats on fixing it! I find it instructive - engines can make the mistake of underestimating losing captures so much that they fail to see a sacrificial forced draw threatened by the opponent if the node where it happens is pruned or outside the main search...

Re: Rabid Queen only

What is a "rabid queen"? A 'rabid' piece is one that checks the opponent's king continuously so that if the king takes it, the owner of the 'rabid' piece will be in stalemate, but if the king doesn't take it, it will be giving perpetual check. A 'rabid rook' moving along the seventh rank and checki...

Re: Why is the MIT License unpopular in chess programming?

So my conclusion is: 1. If you want to grab a strong engine, make some tweaks and call it your new project you can do that legally with the strong engines that are available. I advise against this, because someone else's code is not native to your brain since it was written by someone else. These p...

Re: Why is the MIT License unpopular in chess programming?

I don't understand what surprises you. Would you agree someone to make money out of your open-source project in which you have invested much time and effort? The best kind of charity is unconditional one. Opening the source is charity anyway. If an author hopes to make any profit from his code, s/h...

Why is the MIT License unpopular in chess programming?

What follows is just a random rant, I'm not even sure if the topic is affecting me much (I've never done any serious programming and I'm not going to let my well-being depend on doing it anyway). As per the Wikipedia: As of 2015, according to Black Duck Software and GitHub, the MIT license was the m...

Re: The Computer Chess Community

I, as a newcomer in chess programming, did not experience rough or even hostile welcome here when I presented my CT800 project. I didn't experience any kind of crazy inquisition, either. Quite the opposite - I'm really happy that my little project now is even on the chess programming Wiki. Imo, you...

Re: Chess Performance enhancing drugs!

Such drugs are helpful for short-term results, e.g. when one is playing an important tournament, but they may have severe long-term side effects (burnout). For continuous improvement of one's mental ability, a normal amount of sleep, physical exercise and a diet avoiding high glycemic index foods ar...

Re: With websites, emails, and downloads will be more change

A drastic improvement of Stockfish will require a revamp of the algorithm - the parameters (constants) of the existing algorithm have likely converged to nearly perfect values already because Fishtest allows to test and adjust the values fast.
