Solution for Puzzle 1 posted August 4th 2009:

(a) Rd1-d8+ and Ra8 Wrongly puts the rook in front of the pawn, blocking it's road to becoming a new queen on a8.
(b) Rd1-a1 Correctly puts the rook behind the pawn.
(c) a4-a5 Although passed pawns must be pushed, this is too soon. After Rb3-a3! white is forced to defend the pawn from the side (d4) or in front (a8).
(d) Kg2-f1 It is good to get the king involved, but again this allows Rb3-a3!
