Re: A position some have claimed will never be solved ...

Regular (bleeding edge) stockfish has a terrible time with it: Searching: k2b3b/8/2N2b2/6b1/1b6/b7/3b2K1/b1b2B1n w - - 0 1 infinite: 0 time: 0 increment: 0 moves to go: 0 1 +0.00 00:00 12730 Kf3 2 -16.50 00:00 79582 Kxh1 Kb7 3 -16.43 00:00 115229 Kxh1 Bdf4 Nxd8 Bxd8 4 -16.48 00:00 132271 Kxh1 Bd6 Nx...

Re: why did they destroy stockfish in finding mates

I don't think a NN adds anything here. A pure move generator is all that is needed. The move generator will know if a position is a win, loss, draw, or something else (which needs expansion). The and/or search already knows how to assign probabilities to the nodes. On the other hand, maybe there are...

Re: Query about notation

You are correct.
Whatever "the UI" is, was lazy.
Minimal is better when it can be achieved, but on rare occasions I see errors even in top engines and GUIs in representing a move by not adding enough disambiguation.

There are some work arounds for the problem explained in the thread. There is absolutely, positively no harm wh...

Re: why did they destroy stockfish in finding mates

Where is a GPU mate solver? 5000 cores just for mate. Should beat SF and Chest :) . I think this is actually a very, very good idea. Ankan's move generator is absurdly fast. So couple this move generator to and and/or depth-first proof search. I have a feeling it might be scary good at mate solving...

Re: *** General user warnings ***

Exactly. IMO the only thing that makes sense to discuss is the IP block problem. You say it can be solved by using a vpn. But what about those who don’t know they have to use this, or those who don’t like to use it. Or give Sam their IP. IMO there MUST aber a solution. An international forum where ...

Re: *** General user warnings ***

We have complaints flooding in because some posters are disturbing other members. Something needs to be done. The posters here are intelligent and can create posts without profanity and insults. I think that much of the antagonizing is deliberate. Obviously, there was animosity about the CTF issue, ...
