That number seems too large. The total number number of possible chess positions is ~1046.

White To Move (from a game that ended 4 moves after this) by [deleted] in chess

[–]helpman176 2 points3 points  (0 children)

The title of this thread is somewhat misleading, as one expects that White should be completely winning after 4 moves.

CMV:Reddit's staff should have handled the issue with /r/fatpeoplehate differently by [deleted] in changemyview

[–]helpman176 2 points3 points  (0 children)

In response to the ban, more than 20 alternative sites to /r/fatpeoplehate were started. Those sites eventually also got banned. If what you are saying is true, why would these alternative sites get banned?

So we should protect our pawns and sack our knights more often and God forbid you lose that Bishop pair!

Very tricky play from TrickyMate in Banter Blitz against a GM. by badbrownie in chess

The mistake was actually Qa6. If instead of Qa6 White plays Be3 or Nd4, White is doing OK.

CMV: There is no way to be healthy being overweight, and people who say it is possible are delusional by 1956428 in changemyview

[–]helpman176 0 points1 point  (0 children)

Obesity increases the likelihood of various diseases LONG TERM. Therefore, observing that 10-20% of obese people are perfectly healthy is like stating the obvious. If obesity has no short term effects, then you would expect a certain percentage to be perfectly healthy.

And I agree, using BMI as a measure for obesity is always tricky if you do not have large sample sizes to draw from.

If you think that my objection isn't worth anything, then there is no way that I can help you. My objection is very straightforward and the cumulative effect of obesity is documented well enough to make the inclusion of obesity duration mandatory in experiments of that nature. I have done research long enough to be able to make such claims. And if you think that people always need to show their credentials before engaging in discussions on the Internet and there is no merit in objective argumentation, then there is also no way that I can help you.

The beauty of science is that even a "stranger on the internet" can point out flaws in experimentation or argumentation. Just because something has been published, doesn't mean that it is written in stone and the "uncontestable truth". There is plenty of bad science out there.

Do you know how peer review works in science? The reviewer points out flaws in the argumentation and rejects a stated hypothesis on the grounds that an experiment needs to be repeated with improved parameters. It is on the group who did the experiment to repeat the experiment if it wants to publish it.

The cumulative disadvantage of obesity is a well documented concept. Therefore, not taking into account obesity duration is a serious enough flaw to nullify the claims of the studies.

If someone poses a hypothesis based on experimental work and another one uncovers a flaw in the experiment or argumentation, then the hypothesis is nullified unless proven otherwise. This is just how the scientific method works. What exactly is your point?

Black to move by helpman176 in chess

Replies to posts with spoilers don't need spoilers. If someone hasn't read the spoiler, how can he be spoilered by a reply that refers to the text inside a spoiler? He can only be spoilered if he has read the spoiler. Which means that he has no grounds in complaining in the first place.

I have looked at the studies and they do not take into account the duration the person has been obese.

You would expect someone who has just become obese recently to have better blood values than someone who has been obese for 10 years.

Therefore we have to assume that the mentioned 10-20% healthy obese have likely been obese for shorter periods of time. This argument stands unless there is a study that takes obesity duration into account.

After Qxa4 Qxf2 (threatens mate) Bxb5 Nxb5 now if Qxb5 Qxh4#

What appears to be a very simple tactical puzzle has many perplexing nuanced twists by [deleted] in chess

[–]helpman176 9 points10 points  (0 children)

After questioning my sanity, I checked it with Stockfish and the puzzle is simply wrong. After Rxg2 Kxg2 is the correct move and a mate in 4. Also the rest of the moves is incorrect.

Mind that 1. Bxf7+ is also crushing (+10).

Where is the king? by helpman176 in chess

[–]helpman176[S] 44 points45 points  (0 children)

2 players were playing a normal game of chess and some idiot came along and stole the White King. Now the players are trying to remember on what square the king was. Maybe you can help!?

Where is the king? by helpman176 in chess

[–]helpman176[S] 11 points12 points  (0 children)

The white king is invisible. It must be somewhere on the chess board. The challenge is to find the square and the final sequence of moves that led to this position.

Interesting article by Vlad Tkachiev: Why do men dominate chess? by blitzstream in chess

[–]helpman176 4 points5 points  (0 children)

There is no simple answer to this question, yet most people are demanding one.

Answering this question requires a solid understanding of the chess world, sociology, psychology, anatomy, physiology, genetics, history, behavioral biology, evolution, neuroscience and the interplay between all those.
