I invite Stick to guess the correct answer based purely on the
subject line. Here's the SHA-2 hash of the XGID so that I can't
bait and switch.

I know this is googlable but, since you raised the topic, I'd like to inform you that
a (positive) number of people want to know what an SHA-2 hash is.

I know this is googlable but, since you raised the topic, I'd like to inform you thatA cryptographic hash function takes an arbitrary input and produces
a (positive) number of people want to know what an SHA-2 hash is.
an output of a fixed length (in this case, 256 bits), in such a way
that it is computationally intractable to invert it, or to find two
different inputs that produce the same output. The output is called
a hash. SHA-2 is a specific widely used cryptographic hash function.
I produced the above hexadecimal string by taking the XGID of my
position and running it through SHA-2 using the following website
(with the output size set to 256):
https://www.browserling.com/tools/sha2-hash
After Stick makes his guess, I will reveal the XGID, and anyone can
then use the website to confirm that the given XGID does indeed produce
the 256-bit hash that I have already announced. If I were to try to
bait and switch by choosing a different position after seeing what Stick guessed, I would be caught in a lie because the XGID of my altered
position would fail to produce the advertised hash.
Since SHA-2 is a deterministic function whose definition is public, one
could try to reverse-engineer the XGID from the hash. In principle this
is possible, but if you can "break" SHA-2 in this way, fame and fortune
await you. You are unlikely to be able to figure out the XGID of my
position more efficiently than by guessing position after position and running them through the hash function to see if you happened to guess correctly.
Assuming the contest is not Stick-limited, I'd like to render my own guess.
I guess that the two options are extremely closely matched in terms of MWC. It's much too close to call which of these two candidate plays is correct.
