Occasionally, however, a win is possible also when the white a-pawn is not on its initial square provided it has not crossed the fourth rank. The additional conditions are that the white king can get in front of the c-pawn and also take the opposition at the moment the a-pawn reaches a5. This superb manoeuvre was first discovered by S. Walles in 1949 and later elaborated upon by I. Majzelis in the following study published in 1956. The outcome depends on who is to move. White to move wins; Black to move draws. The win cannot be achieved by “stalemating” the black king as White’s a-pawn is not on its initial square. But White has at his disposal a very surprising and instructive winning plan!
