Checkmate. That's the aim of the game. There are numerous ways to checkmate the enemy king, but there are common patterns that recur over and over again, and having these at our mental fingertips is essential for when we want to finish the game.

Continuity:An indisputable proof that proves the claimed black hole is a fake.

It appears self-searching Alphazero has not yet been able to find the answer. But undersigned has found an INDISPUTABLE PROOF that the powerful light enveloping all galaxies emanates from the cores of galaxies, meaning light escapes, meaning that powerful light emanates from the core, supposed black hole, of the galaxy. Concept of black hole on which light cannot escapes is wrong, is against the unwritten law of physics which sttes whenever there is fire, there is light, the greater the fireball, the brighter the light. Look at ALL the galaxies, it is a bundle of fireballs and light. Such is the clue. I will disclose this indisputable proof no scientist can disprove, a week from now..

To respected GM Daniel King and Dr. Dennis Hassabis:

No need for Alphazero to search. I have found an indisputable proof why black hole does not exist. I will disclose this in due time. Regards to you both.

To respected Dr. Dennis Hassabis and GM Daniel King:

Maybe this is getting far but I just contend Alphazero can solve this 50 year old modern time greatest hunt in science, the black hole. Maybe this can be done: connect directly or through long distance line, the astronomical telescope to hardware of Alphazero to enable Alphazero to read first hand, recognize (positive and negative) that brightest glow/light enveloping Milky Way and to search the source of the light.
A number of simulated black holes were performed showing the big black circular spot, claimed the black hole. But the fact that black hole is photograped proves light escapes. That black spot is just the source center object from which light emanates/escapes.
Concept of black hole which even light cannot escape is against the unwritten law of physics which is: the bigger the fire, the brighter it glows. Look at all galaxies, the biggest fire and the brightest glow that envelope galaxy is concentrated at the middle of galaxy. This cannot be the making of the billions of stars surrounding the galaxy, just like the glow of the sun overshadows the glow of the planets.

Hmm, it might be the board's rules but

FEN k*7/8/b*7/2K*P*4/8/8/8/7-B w - - 0 1 (remove the * in the text) is the FEN (When I download I get [Event ""]

With due respect to Dr. Dennis Hassabis, please see if the following is possible (a) or is true (b):

(a) Can self-searching Alphazero search and recognize if the visible light that envelops all over Milky Way originates from the center of Milky Way. Light and gravity have both positive and negative. Alphazero operates on the same positive and negative. Permit undersigned to propose: Feed the actual astronomical telescope photos of the Milky Way to Alphazero hard ware (brain) and simulate and command the positive and negative of alphazero to recognize the positive and negative of the thick bright lights encompassing all over Milky Way and to trace the source of the light. If the light originates from the center of Milky Way , then it proves light escapes , there is no black hole.

(b) Why stockfish lose to Alphaqzero. It appears like this, subject to correction by Dr, Dennis Hassabis : Alphazero is programmed//commanded to self-analyze some 80,000 moves a second from each position as played at that TIME on the board. It means that every position is considered new by Alphazero but is subject to the same programming//command. Then Alphazero selects the best move thereof. While stockfish has storage of moves per second, by the millions, all activated all the time chess is played. But not all positions are on the stated storage millions of stockfish because there are billions of variant moves in just the first 10 moves, thus Stockfish is lost on positions not in its storage. Both Alphazero and Stockfish operate on positive and negative but the programming and command differentiate the positive and negative from one another...
