lotus_elise puzzle no.26

easy but nice

Nice But solution is to long... This game can be finished in two moves...

     White - Black

1)    ...       Bxf7+

2)   Ke7      Ne4++

  Black wins by check Mate

cmdodanli, 2... Ne4+ isn't checkmate because of c5, which would be foolish, and Qd3 which would be less so.

I wonder why the puzzle isn't recognizing the last move as checkmate -- it looks like a bug.

1)    ...       Bxf7+

2)   Ke7      Ncd7+

3)   c5        Bxc5#

The rules of chess composition state that every problem must be 'legal', meaning that the position in the problem must be reached from the beging position through a series of legal moves. For example, white pawns on g2, h2 and h3 are ilegal. In this case, how did bishop get from f8 to g5 if g and e pawns didn't move? "We still don't have aviation in chess" - Kortchnoi.    

lotus didn't flip the board when making this puzzle, so most of the pawns are close to promoting.

Ahh, gotcha, in which case Zor2046's overly pedantic gripe about the position being illegal is incorrect too.

In this puzzle you would be right, but if lotus selected to flip the board, you wouldn't have that problem and have a mate.

Rules of composition? is this an official problem solving competition or just fun? I say "Let's have  some fun!". Very nice.

Particularly since the positions of the e2 and g2 pawns are not relevant to the puzzle's solution -- put the e2 pawn on e3 and nothing about the puzzle's solution changes.
