# 10/6/2011 - Converting in Efficient Manner

interesting

excellent illustration of how to avoid forced draw and win the game(not killing black's rook with white's rook)

You have solved this problem!
3. Rh8+

Beautiful.  After 1. Kc6, black cannot move his king; he must move his rook.  Unless he can do something about it, pawn to d7+ will be checkmate.  There are two ways black can "do something about it" i.e. be in a position to capture the white pawn at d7.  However, whichever one he chooses (... Rxh7 as in the daily puzzle or Rd8) leaves black vulnerable to mate from a queen or rook at h8.

Not counting delaying interpositions by the black rook, I see two alternative lines if black chooses the 1. ... Rd8 approach.
1. ... Rd8, 2. cxd8=Q+   Kxd8, 3. h8=Q#
or
1. ... Rd8,  2. h8=Q    Rxh8,  3. Rxh8#

For white a less efficient, but still effective line would be:
1. ... Rd8,  2. d7+   Rxd7,   3. h8=Q+   Rd8   4. Qxd8#

easy

Nice puzzle.

if we all think its too easy then make some suggestions, as our friend says, its good for learning

easy

rule of thumb,to promote or in this case win,position King in front of pawn.1,Kc6,black had only one piece to play,Rh7,2,pd7...R8#

:)

easy

easy to fall into the stalemate trap with Rxh7 instead of d7+.  A good lesson to always be on the look out for an accidental stalemate.
