Puzzle #288 solution:
Study by F. Amelung 1897. The correct answers were:
a) The solution is:
[Event "Puzzle #288"][Date "2015.12.07"][Result "1-0"][SetUp "1"][FEN "7R/7p/5P1k/4PKpP/8/8/8/8 w - g6 0 1"]1. hxg6 {en passant} Kh5 2. Rxh7#
b) The most important detail to start with is to find out what could have been black's last move:
(#) The h7-pawn is blocked and has not moved
(#) The h6-King could have been on the g7-square; however when in check he would have captured the h8-Rook and not move away. The second aspect is how could the f6-pawn move there when the f5-King blocks it? The h6-King has not moved
(#) The g-pawn is the only one capable to move. He could not be on the g6-square because the f5-King would be in check. The only possible position for it was on the g7-square and because of this the last move was "g7-g5". This enables the en-passant first move of the solution.
