Re: correspondence chess in the age of NNUE

I disagree about the part of OTB games. In OTB games it is impossible to memorize everything and the better player may get his opponent out of book assuming the better player change his choice and does not use a fixed opening. memorizing 1,000,000 different lines in the opening is practically imposs...

Re: correspondence chess in the age of NNUE

Taking out really weak players (probably not even using a computer) the draw rate for the past three years is already close to 60%. If you take out weak players, like those who only use a computer to check some positions, it raises over 75%. We're still talking over 140,000 games for just three yea...

Re: A thought on originality

One man finds a pretty math equation and puts it into his chess program. Then like a million itty-bitty workers, they smash the giant slab of marble that is "the game of chess" into magic pixie dust.
