Rachels and Speelman collaborated on this puzzle for a while and came to the conclusion that, if the black and white pieces are switched, the position can be reached half a move earlier.īoth chess masters are fine gentlemen and it seems nobody wanted to take credit of whom found the quicker solution. All solutions without the pawn fail, because the white king simply cannot make illegal moves and walk through a check. The problem is solved, thanks to Black's stunning excelsior pawn walk. Rachels points out that the solution may also begin 1. The other solution of the puzzle is in Jonathan Speelman's replayer analysis. The black bishop maneouver to b7 was necessary. What stands out is that the white king wasn't even touched in the first three moves. Note, White was also able to play c3 in the first move. Furthermore, you will have experienced the creative beauty of the puzzles and how much work Rachels put into them. If you were really able to find a solution, the satisfaction must have been immense.
