Winning a game without moving a checker

Post by EdTrice »

Recently I had the opportunity to win the following wager. I made this bet:

I can play an entire game without moving a checker, allowing my opponent to finish the game with all kings while I had none, and still have a position any master will agree is a draw at the end.

Let's see who can solve this riddle.

Ed being a creator of checker trivia I must ask if we are to assume that you are playing a normal game of checkers or are playing checkers at all? Your question does not say. There are many other games played on a checkerboard as you well know.

Yes, a real game of checkers is played, all moves being legal, and plausible, and any checkers master would find each move by both players perfectly acceptable.

Did you play protest checkers (if it exists, but protest chess does, so why not...) ?
In which other kind of checkers can you skip a move ?

"each move by both players"--your question states that you were not making any moves, so which is it?

Nope, this was not protest checkers, just regular old 8x8 checkers.

My question was posed the following way:

I can play an entire game without moving a checker, allowing my opponent to finish the game with all kings while I had none, and still have a position any master will agree is a draw at the end.

...and I was able to do everything stated above, as it was stated, thereby winning the bet.

It is a bit of a "thinking puzzle" :)

P.S. I have also won bets in bars where I claim I can finish 3 full mugs of beer before my opponent can drink a shot. It's all in the wording, then the execution of the wording... so there is your hint!

From the starting position in the game of checkers, play:

1. 11-15 23-18
2. 8-11 27-23
3. 4-8 23-19
4. 9-14 18x9
5. 5x14 22-17
6. 15-18 26-22
7. 11-15 17-13
8. 7-11 13-9
9. 6x13 24-20
10. 15x24 22x15x6
11. 1x10 28x19
12. 14-18 31-26
13. 3-7 26-22
14. 10-14 22x15
15. 11x18 32-27
16. 7-10 30-26
17. 8-11 20-16
18. 11x20 26-22
19. 2-6 22x15
20. 12-16 19x12
21. 10x19 12-8
22. 6-9 25-22
23. 19-23 27x18
24. 14x23 8-4
25. 23-26 4-8
26. 9-14 8-11
27. 26-30 11-15
28. 20-24 15-10
29. 24-27 10x17
30. 30-26 22-18
31. 13x22 21-17
32. 26-23 18-14
33. 27-31 14-9
34. 31-27 9-5
35. 23-18 17-13
36. 22-26 13-9
37. 26-30

...and you will reach this position:

You will be able to verify that:

1. There is a white checker unmoved on square 29.
2. Red has 3 kings and 0 checkers, white has 0 kings and 3 checkers.
3. White to move can draw.

So, white played the entire game without moving a checker, and that checker was on square 29.

Red has "all kings", and white has "all checkers" in the final position, which is a draw.

Furthermore, all of the moves in the game are plausible, i.e. the game was not "contrived".

This satisfies all of the conditions specified in the bet.
