This puzzle contains errors, the author is working on fixing this! Sincere apologies for the incovinience!

Dear Puzzling SE Users,

Okay so the last time I tried to take over Puzzling SE I failed. Yes the mods were rescued. How Rubio managed to survive drowning, and Gareth survive being buried alive, I don't know. I generously gave them access to WiFi, so maybe they found a lifehack to avoiding death. Who knows. Anyways, I have a new plan! And it'll be ingenious ... of course, you'll have to figure out how I'll do it this time. Of course, I doubt you will be (but again Deusovi is free so maybe not) but I WILL TAKE OVER. And to mark my celebration of future events (I don't care if it doesn't make sense) I'm showing off my latest chess game! Hahahahahahahaahahaha hmmmmm

enter image description here

Yours truly,
North.

    $\begingroup$ If these are your first steps what do you class your previous attempt as? $\endgroup$ – L_Church May 9 '18 at 8:15

  • $\begingroup$ @L_Church Well, these are my second attempt, this lists my first steps to my new plan. $\endgroup$ – North May 11 '18 at 15:49

The gibberish can be decoded ...

... using the Caesar cipher. Each part between 2 brackets is using a different shift (25, 21, 10, 18, 15, 3 repectively). The decoded text looks like this (spaces added by me):

[xor bitwise table]
{pawn movement is equal to 1 any other piece movements are equal to 0}
[when white moves a pawn and black responds with a pawn movement or white moves a piece and black responds with the same piece or when white castles and black castles on the same turn or use bitwise function or]
[when white moves and black moves a different piece/pawn use function and if white castles and black does not use same function as above]
[when either side captures replace function with xor]
{zero is equal to dot all ones are dashes}

I tried to decode the moves ...

... using the information above (however, I have no idea what the first part is supposed to mean):

1. e4 e5 1 or 1 = 1
2. Nf3 d6 0 and 1 = 0
3. d4 Nc6 1 and 0 = 0
4. d5 Nce7 1 and 0 = 0
5. Be3 Bg4 0 or 0 = 0
6. Nbd2 Bxf3 0 xor 0 = 0
7. Nxf3 Nf6 0 xor 0 = 0
8. Bb5+ Nd7 0 and 0 = 0
9. O-O c6 0 and (as above) 1 = 0
10. c4 a6 1 or 1 = 1
11. Ba4 b5 0 and 1 = 0
12. c5 bxa4 1 xor 1 = 0
13. Qxa4 dxc5 0 xor 1 = 1
14. Bxc5 cxd5 0 xor 1 = 1
15. exd5 Nxd5 0 xor 1 = 1
16. Bxf8 Kxf8 0 xor 0 = 0
17. Qa3+ Qe7 0 or 0 = 0
18. Qxe7+ Nxe7 0 xor 0 = 0
19. Rfe1 Rc8 0 or 0 = 0
20. Nxe5 Nc6 0 xor 0 = 0
21. Nxd7+ Kg8 0 xor 0 = 0

This gives the following "Morse code":

-........-..---......

This is basically impossible to decode (assuming it is correct), because the letter separators are missing. The online tools didn't deliver anything, except of hundreds meaningless possible decodings.

  • $\begingroup$ Hmm. I must've screwed up somehow. Sigh I'm an idiot. $\endgroup$ – North May 12 '18 at 0:40
  • $\begingroup$ Sorry. This isn't your fault. My problem. I screwed up the XOR truth table and messed up the pairings. I also realized exactly how tedious it would be to break up all those Morse Code. $\endgroup$ – North May 12 '18 at 0:46
