Reason for choice: I like helpmates with their
clear-cut play free from duals and solutions in less than
the required number of moves. I particularly like to see
strategies which would never occur in a normal game of
chess. In the problem by Vieira, Black starts by unpinning
a White Knight in both settings, the White King could
capture the Black unit which has allowed the unpin, but
waits until the unpinned Knight has moved and been replaced
by a Black unit. Difficult to solve, one can only marvel at
the time and effort required to compose such a problem.
