Re: Chess solved?

Do you mean this "stroke of good luck" to be related to chess in general (i.e. the basic rules of moving, winning and drawing) or do you mean all that plus the specific (opening) position we have? If you mean the former (i.e. the stroke of good luck covers all chess positions), there are theoretica...

Re: An idea for a different type of tournament

Yours is an 18 point handicap. This is another 18 point handicap although it should be able to find faster than mate in 23. stockfish 7, Mate in 23 depth 42/66 [FEN "r1b1kbnr/8/8/8/8/8/PPP2PPP/RNBQKBNR w KQkq"] and a 14 point handicap Stockfish 7, Mate in 20 depth 36/58 [FEN "r1b1kbnr/8/8/8/8/8/P6P...

Re: Chess solved?

2. You said that I " just come in here with silly claims... ", but if you re-read the thread (just my posts - it doesn't take long - I've done it myself!), you'll see that most of my posts are actually responses to questions that you have asked. So... if you don't wish to read that chess might be s...

Re: Chess solved?

Questioning whether an idea will work is completely legitimate, and is actually valuable feedback ( :!: ) As far as I can see we got stuck at: you have no idea to begin with. Your case is built on "it would be surprising if no idea that will work existed". Questioning an idea with reasons from Comp...

Re: Chess solved?

We're not quite devoid of proof: we know that it's not possible to force material gain in the first 30 or so moves from the starting position. We didn't know that in the last century. Where do you get that idea from? We certainly do not know that. If it's possible to make material gain early from t...

Considering there are more possible games then atoms in the universe, it is not so surprising that the game has held out. I could argue that the fact that in 10 years or less we are approaching near...
