 Oh, of course!! I hate to sound immodest, but people are always wanting my autograph because I'm a tic-tac-toe GRAND MASTER!


tic tac toe is dead. same with checkers, nim, go fish, and baseball.


People still play checkers. didn't you see my post about checkers Gms?

They solved baseball!?

Let me guess:  It's always a loss for the Cubs?

i am in denial that a person would be okay with labelling themselves as a checkers GM.

Not true.  The most money wins often, sure, but how do you explain the two Marlins World Championships, not to mention the upcoming 2010 Tigers world championship?

It seems pretty clear as to what he means by "solve chess".

 

That's a good question. People already memorize whole games that are notable, so I don't think it would be a stretch to memorize "the perfect game". In which case you'd basically either have to rule out people playing that game, or just not play.


but learning all the possible variations will be like learning all the known opening variations and sub-variation, multiplied-hundredfold, since you'd have to do this for all the game, and not just the first 10 or so moves.

Computers are stronger than me now, but that doesn't stop me from enjoying a game.

i can't explain that because i was joking.

Now..., when computers solve arm-wrestling I'm out.

The machines solved arm-wrestling long ago.  It's called the hydraulic cylinder.  I almost beat one once;)

if the computer has solved every single possible move and wins all the time then that requires somebody with the greatest chess knowledge in the world and then that does not make it fool proof so then somebody can find a mistake in it and then that gives people a reason to carry on playing.

NO WAY!

haha  the geek knows for sure, he's mildly familiar with chess and computers--combined.

the meaning.


If both sides play perfectly, is White's first move sufficient advantage?

...


Are we so sure that the starting position isn't one of mutual zugzwang and that it can't be a win for Black?

I've enjoyed reading this post. There are some insightful thoughts here.

Regarding checkers: It has not been "brute force solved". Checkers has been loosely solved through a sort of sandwhich method. That means there is a very large endgame tablebase for checkers.  And there is an opening tablebase that has become so big that, through a specific opening, reaches the endgame tablebase data. That means you cannot put any position into a chess database and it will solve it. It simply means for a computer to beat you, the game has to be played from the very beginning so both databases can be used.

Checkers is simply too large for our current computing technology to handle. There are 500 billion BILLION possible checkers positions (5*10^25).  According to the guy who was the purveyor of checkers cracking, if a human foot contained 50,000 checkers positions, he would have to touch every inch of the earth to find every checkers position. So brute force solving is really not possible currently.  The only way they were able to do it was pruning a ridiculous number of positions to do it.  Even so it took the team 25 years to complete the project!

By comparison, chess has about 10^50 number of playable positions (10^120 if you ignore the 50 move rule). By comparison it is estimated that there are 10^78 number of atoms in existence, everywhere, period (according to NASA).  10^50 is so immensely mind-blowingly large there is no way that it will be solved in our lifetime. Not even through a sandwhich method.

Now to the question, would I still play if chess was solved? Yes, absolutely. But it doesn't matter. I would be surprised if a solution to chess were able to be reached even in the next 200-300 years, taking exponential improvements in technology into account.

It would be funny if chess was actually a win for black but with a million games
in databases and a clear winning percentage for white that seems highly unlikely.

The game tree complexity is greater than the number of atoms in the universe, so you would need another universe(s) to store the results to solve chess.  See Shannon number.  http://en.wikipedia.org/wiki/Shannon_number

And as others have said, it is possible that black can win every game.  It seems intuitive that white would either win or draw, but that cannot be known until it is solved.  Which I don't believe is possible given the number of combinations.  It would take a giant leap in technology past computers and even quantum computers to solve chess.

But if it were solved, people would still play.  No person could memorize the solution, even if it were known.

Well but you need to think out of the box for a minute, most of those games are human vs human right?

What if undiscovered opening lines or variations not currently known or considered to be solved turn out to be better that what we play today?


Isn't that how opening theory (and chess) evolves?


If you put sufficient computer horsepower (which does not exist on our planet today, not even those supercomputers they use for simulations at the nuclear weapons labs) to the question of solving chess, chess can be solved. I just don't see that happening in my lifetime.


I think that the computers we have now have sufficient power to solve chess, if it were solveable. I just don't think it is.
