I think chess is the epitome of art.
But a chess program is never finished.
The journey is the destination, and the path is always uncertain.

And with these logical, clear, and completely unassailable words, the question of whether or not to release a chess program simply doesn’t arise.

I’m quite clear on this: anyone who has argued that way hasn’t understood the point of science. Science means research, and that applies especially in the field of chess. There’s absolutely no doubt about that.

As I said, you can sugarcoat everything to make it look the way you’d like the world to be. Reality usually looks quite different.

My code is as disgustingly ugly and worthless as I am. That's why I don't release it.

Hi Jim,

to Fizbo 2.0 JA:

why is eval +1.0?
Do you have a reason for it?

I compare the official 2.0 with 2.0 JA.

Hi Frank,

Probably an uninitialized variable somewhere that microsoft compiler auto-initializes but clang compiler doesn't. I'll take a look.
