What? "Untruth is not beautiful"? Art (literature, painting, movies...) is lies — and beauty.jp wrote: ↑Sat Apr 11, 2020 12:35 amBeauty is just subject to truth. That's all.

No one said anything about proof, though without proof it can be difficult to know truth.
What?? You think art is "lies"? No it is not! In what way do you think the painting is lying to you??Marek Soszynski wrote: ↑Sat Apr 11, 2020 12:44 am What? "Untruth is not beautiful"? Art (literature, painting, movies...) is lies — and beauty.

I have been very impressed with Ethereal 12, it is very, very strong and now with a more refined positional style to boot.
But the way Lc0, even on my very weak hardware (laptop with built-in Nividia card) beat it from a position where Ethereal thought it was +4 is the most amazing thing I've EVER seen.
Witness this amazing game.

To do this to a weak engine is one thing...but to Ethereal?
With a BISHOP vs a queen?
What the hell is going on here? Amazing.
Entertaining game, no doubt - thx for sharing...

By this measure, neither the Evergreen game nor the Immortal game is beautiful.jp wrote: ↑Fri Apr 10, 2020 11:47 pmThe word "blunder" is loaded, so it should probably be avoided.Dann Corbit wrote: ↑Fri Apr 10, 2020 11:29 pm I'm with BrendanJNorman.

My first rule of a beautiful/amazing game is to play through it with Winboard.
The importance of this step cannot be over-emphasized.
For instance, if you analyze the Immoral game or the Evergreen game, the computer will point out "blunders" like not capturing a piece that was offered. But when you watch the game unfold unaided, it is a thing of beauty. This game is one of those.
But a sacrifice should not be called "beautiful" if it turns out to be unsound, so it does matter in the end whether it loses with best play. (It can still be "amazing", because that includes everything, including "amazingly bad".) If best play after a sac leads to a draw, that's passable but still not as "beautiful" as if it wins.
So the unavoidable question is: when the Q is sacrificed, what is the theoretical result of that position?
