Now this is bedevilment indeed!

Say I believe that most gorks are deeks.

I hear someone saying to the interested world:

"Most gorks are deeks."

Good so far!

But then she says:

"Here, as an example, is a gork I randomly chose who is unsurprisingly a deek."

And when I look, I see the claimed gork is not a gork, or worse, it is a gork
but is not a deek.

Should I stay schtumb?

Follow the thread in chronological=posting sequence, and you will see I am (if
anything) the victim.

Often, very probably usually - but certainly not always.

Referring back to my nomenclature, Type (b) finds are often superior as they are
cheaper in time terms.  Types (c) and (d) can be dangerous, but only if they
result in shuffling cycles as demonstrated in the subsequent example the OP
provided.

You must be one of these "troll" types the OP referred to, right?  A quick
glance at my EGTB folders tells me that the average file size for an EMD
tablebase is about 100Mb (counting multiple files for the same tablebase as one
file), and I haven't yet got far enough into the sixes, each one of which raises
the average.

Cacheing is thus only a small benefit, as successor EGTBs (sometimes, when
post-promotion as opposed to post-capture, about as large) also have to be
stored.

What do these evidently non-mechanical big HDDs you use cost?

How many others use them?

Can I have some?

It didn't shuffle in the example provided of them shuffling.  Here is the
example the OP provided and to which I objected:

[D]8/2k5/8/3R4/8/8/5K2/8 w - - 0 1
