Re: The Aesthetically Pleasing Attack

So the question is, instead of the blunder of 24.. a4, does ..Rf7 hold for black?

Re: The Aesthetically Pleasing Attack

Nice. I don't think Francesca had a clue that was happening. Maybe some more eval work needed, then.

Re: Stargazer under the Rise of Orion (various versions of recently progressing engines)

Re: JS Schach's alpha-beta approximation

As to avoiding negamax: it requires all code that appears in duplicate to be split into separate sections for max- and the min-player, differing only in the < and > operators. For a very basic search this is not really a problem (the required single conditional is easily predicted). But in principl...

Re: An alternative to IID

Took IID out (of my oldie) and replaced it with a full ply reduction without research and it gave me +17 elo after 5000 games. Not sure if that works for modern searchers. Interesting idea.
