Is There a Logical Fallacy In Chess?

[Pargat Perrer]

Things that make no sense are not necessarily a logical fallacy. Things that are supposed to make sense but do not, that is a logical fallacy. There is...

I saw a headline in online news this morning: "Environmentalists Urge Halt To Amazon Gold Rush". I believe it was referring to the Amazon...

How do you decide when to stop the analysis and make a move in these ICCF games? Especially for the most complicated positions....

[Pargat Perrer]

That is very interesting, because I remember Mr. Bonham saying to me that chess variants, and he was specifically talking about Option Chess, shouldn't...

[Pargat Perrer]

Thank you for that Peter, and I formally apologize for calling you a troll. I also apologize for my use of the word "everyone" which you were...

[Pargat Perrer]

Hey Bob, I had no idea that you knew Paul Bonham personally and even attended is wedding. If I ever do hear from him, I will forward him your condolences....

[Pargat Perrer]

I'm glad you like the discussion of chess rule history. Everyone talks about castling and en passant as "special" rules that were added at specific...

[Pargat Perrer]

I addressed this question earlier this year I believe. I knew Paul Bonham when he was working on system software at MIT. He and I shared an interest in...

Then tell me, WHO was I trolling in post #1?

People seem to be getting the impression I don't like this rule. I don't think I've said that...

[Pargat Perrer]

Of course you are fine to disagree with me, but why are you going on so much to me about capturing the King when I never said that someone actually plays...

[Pargat Perrer]

I don't know the detailed history of chess, so I would like to have a discussion with a true chess historian and find out if he or she knows when FIDE's...

It seems you are just trolling, and you are missing the whole point of this thread.

If you look back at post #8 in this thread, which was...

I just realized that Rf2 is ambiguous, both Rooks can move to f2, but i meant the Rook on the f-file, so that the Black Queen is still pinned. This invokes...

[Pargat Perrer]

Peter, I am not trying to suck anybody into anything. You wrote about my initial post "Nothing illogical about this" so in fact it is YOU who...

[Pargat Perrer]

Ok, I downloaded the FIDE Laws of Chess and found the appropriate clause:

3.9 The king is said to be 'in check' if it is attacked by one...

[Pargat Perrer]

Yes, Harvey, that is how everyone in chess agrees to interpret things.

What I want to see is the exact rule in the official rules that makes...

[Pargat Perrer]

If it is an illegal move to move your King into check, then it must be an illegal move to move another piece when that move exposes your King to check....

[Pargat Perrer]

But Peter, look at it from the point of view of someone programming an engine and implementing the rules.

The rules say a piece pinned against...

[Pargat Perrer]

In the course of testing a chess variant engine, the following position came up which I will reduce down to the key pieces:
