Binary Chess Mystery Cache

Congratulations to trollers for being the FTF this interesting cache.

An interesting puzzle involving Chess and Binary. Not two words you often hear in the same sentence!

The result will lead you to a small screw top plastic coffe jar easily accessible just by the side of the footpath, with nearby parking and within a mile of the listed coordinates. The difficulty rating is for the puzzle, the cache should be an easy find.

If you fancy yourself as a chess playing mathematician then this puzzle is for you!

You don't actually have to know how to play chess but you will need to know how to read chess notation and understand binary digits. However if these are unfamiliar subjects I'm sure Mr Google will be able to fill in any knowledge gaps you may have!!

First of all you will need to play through the following game of chess:-

1. e4 e6

2. c4 Nc6

3. g4 f5

4. f3 Nf6

5. Bg2 b5

6. a4 bxa4

7. Rxa4 Bb7

8. b4 a5

9. b5 Ne7

10 d4 c5

11. dxc5 Rc8

12. Qd2 Rxc5

13. Qxa5 Rc8

14. b6 g6

15. Ne2 Bg7

16. c5 O-O

17. O-O Nc6

18. Qd2 Ne5

19. Rb4 Nc6

20. Rb5 Ne7

21. Bb2 Kh8

22. Ng3 Bh6

23. Qxh6 Rg8

24. Nc3 Bc6

25. Nce2 Bxb5

26. Qc1 h6

27. Qxh6#

If you have done this correctly, white has just won.

Now you need to convert all the chess pieces still remaining on the board into coordinates.

So, starting with row 8, you need to write down all the pieces still remaining in that row, in a binary format, then convert the binary number into a decimal number.

Repeat this with row 7, row 6, etc. and you will now have a list of numbers that should look like a set of coordinates.

Enter the coords into your GPS and away you go! More help about the actual cache can be found when the correct coordinates are entered into the checker below.
