I have four puzzler friends Levy, Aron, Roxy and Cass. Last night when I was just about to sleep, a stone came straight through my window. It had a puzzle on it.

It read:

I solved it, and it also told me who threw the stone.

Can you?

    $\begingroup$ I don't get why your friends are hating on short people $\endgroup$ – Adib Oct 30 '17 at 5:58
  • $\begingroup$ For the last tuple/piece, b is missing. Is it intentional or should it be there? $\endgroup$ – Mea Culpa Nay Oct 30 '17 at 7:51
  • $\begingroup$ @Adib you got it in the wrong sense. $\endgroup$ – prog_SAHIL Oct 30 '17 at 17:53
  • $\begingroup$ @MeaCulpaNay it is quite intentional. $\endgroup$ – prog_SAHIL Oct 30 '17 at 17:54

It's a

Chess game

Exactly, it's a

Chess game written in Algebraic notation itself coded in ascii code written in binary format.

If we decode the binary code and reshape it, we got :

1 e4 Nc6
2 d4 Nf6
3 e5 Nd5
4 Nf3 b6
5 Bc4 e6
6 O-O Bb7
7 Bb3 Na5
8 Bxd5 exd5
9 b4 Nc4
10 Nbd2 Ba6
11 Nxc4 dxc4
12 c3 d6
13 Re1 Bb7
14 exd6+ Kd7
15 dxc7 Qxc7
16 Ne5+ Kd8
17 Bf4 Kc8
18 Qg4+ Kb8
19 Nxf7 Bd6
20 Bxd6 h5
21 Bxc7+ Kxc7
22 Qf4+ Kc6
23 Qd6+ Kb5
24 a4+ Ka6

So the solution is

25 b5+ Ka5
26 Qb4+ #

    $\begingroup$ So... who threw the stone? $\endgroup$ – Sid Oct 30 '17 at 8:30

    $\begingroup$ What is the significance of the Bs trailing the binary, and why does the last binary not have one? Can you include the chess moves after they have been converted from ascii? $\endgroup$ – Tony Youngblood Oct 31 '17 at 4:29

In addition to purplepsycho's answer the person who threw the stone was:



1. e4 Nc6 is Nimzowitsch Defence named after Aron Nimzowitsch

  • $\begingroup$ I found it's name too, but why would he trew the stone? Or someone playing versus him on a famous game? $\endgroup$ – Mathieu Oct 30 '17 at 9:45
  • $\begingroup$ We know that the solution told him who threw the stone and we know that his friends are puzzlers so I think assuming that it's because of the same name is reasonable. @purplepsycho $\endgroup$ – Oleg Oct 30 '17 at 9:51
  • $\begingroup$ +1. Although purple solved the main part so I had to accept his answer. $\endgroup$ – prog_SAHIL Oct 30 '17 at 17:52

    $\begingroup$ Okay. How are two people who share a name logically connected? $\endgroup$ – Octopus Oct 30 '17 at 19:59
