ROADRUNNER: World's Fastest Supercomputer

I'm not sure why chess can't be solved earlier.

If it can be proved that chess is a win by finding an example of, say, an irrefutable "mate in 70" from the start position, then not all permutations would need to be analysed.

A mate in 70 is already a long way to go, but imagine now that it's mate in 500 moves ... or worse, draw : you've to prove all the lines from the beginning are not winning ...

I know it's a draw...Begin there.

I am sure the starting position is zugzwang, as just any move weakens the king safety.

That's illogical. After 30 years of play I know beyond doubt chess is a draw. It takes real tangable material advantage for one side to win and 99 out of 100 times a pawn up isn't enough to win. Winning is hard, even with the advantage of space and material. Unless it's overwhelming of course.

The human brain is still the fastest supercomputer. According to this source it is handling 10 quadrillion instructions per second, but it really is hard to say.

Thanks Swami. I got your pm.

It's incredible how the human brain is so small but can still outperform even the fastest supercomputers which are in the size larger than a basketball field.

Not likely, i.e. can a human calculate faster than a computer? Nope!

However, there are limitations to the code. Crappy code...Crappy output.
