How Is Chess Meaningful in the sense of Mathematics?
Sure it's all relative.
But you tell me, how this even matters?
If I give you the answer would you become instantly a better chess player? No you wouldn't.
Maybe over time but not right away.
Go train. Get better.
I don't compare Go to captcha. But I point out that the human mind has such hard coded abilities (like image recognition) in which it is still better than computers. Go is like a mosaic picture and to make sense of it on larger boards where simple tree search gets too costly for computers may be easier for humans.
