The code has multiple occurrences of 3 or more consecutive letters without numbers and numbers without letters.
Like fdca and 6154.
In chess, every square has one letter and one number, like D5.
To make it interpretable as a series of chess moves, we need a way to pair up letters with numbers.
There would also need to be just as many letters including 0 and 9 as there are numbers from 1 to 8 in the code.
But I count 30 occurrences of numbers between 1 and 8 and 34 occurrences of letters including 0 and 9 as letters.
It's 64 hexadecimal characters long, or 32 bytes, which is a 256-bit binary string.
That's a common size for an output of a hash algorithm such as SHA-256, which means that this could possibly be the hash of a file.
Publishing it is a threat or message to whoever else has the file (and can compute the 256-bit hash from it) that the file is in the possession of the person posting the hash.
