Puzzles and Curious Problems by Henry Ernest Dudeney: $246$
- Transferring the Counters
- Place ten counters on the squares of a chessboard as here shown,
- and transfer them to the other corner as indicated by the ten crosses.
- A counter may jump over any counter to the next square beyond, if vacant,
- either horizontally or vertically, but not diagonally,
- and there are no captures and no simple moves -- only leaps.
- Not to waste the reader's time it can be conclusively proved that this is impossible.
- You are now asked to add two more counters so that it may be done.
- If you place these, say, on $\text {AA}$, they must, in the end, be found in the corresponding positions $\text {BB}$.
- Where will you place them?
