Here is one I ran across last night from Willie Ryan's 1938 book
Scientific Checkers Made Easy:
In a note, the Bronx Comet sez:
"A good player never relaxes until the game is over (good to the last move). Black has two logical looking moves at this point (---- and ----). Offhand, both seem to draw, but the wary expert, who always plays slowly, is ever on his guard to avoid fumbling an ending, soon discovers that one of them loses as follows:"
(In the actual note, Willie gives both moves and the blunder; also "soon" is a relative term...).
The "wary expert, who always plays slowly" then presents a forced-loss move sequence analysis for the blunder (which, needless to say, he did
not chose in the actual game) from this position :
Diagram 1. Black to blunder and lose
1. The two move choices are ________ and ________?
2. The blunder is ________?
3. And, bonus points for the forced-loss sequence, about sixteen moves (which I, myself, alas, was unable to discover without finally looking at Willie's notes. No surprise there, I'm sure...).
The game was Stanley R. Morey vs. Willie Ryan, Cedar Point, Ohio, 1933.
There you have it from William Francis Ryan, the one-and-only... .
