Answers.Body: <p>When normal moves don't seem to work to solve a problem, you have to look for special moves like underpromotion, castling or en passant. The latter is the case in this problem, as 1. d4+ exd3 e.p. (forced) 2. Qbf4# mates.</p>

  When normal moves don't seem to work to solve a problem, you have to look for special moves like underpromotion, castling or en passant. The latter is the case in this problem, as 1. d4+ exd3 e.p. (forced) 2. Qbf4# mates.
