White to play and mate in two moves

I have never seen a problem-solving program that would solve it .

we're assuming that black doesn't blunder right?

Mate in 2 ?? Impossible , quickest I find is 3 .

nope not in 2 moves!

I don't see it.  It would be nice of you to make it a puzzle rather than a diagram.  That way, I can be enlightened.

Okay, I'm done here.  I like to study for as long as I choose.  I'll go read a book.  They don't make decisions for me.

yep, no mate in 2. No engine can solve this 'mate in 2' because there isn't one! Except for Bxc7+ any other move by white allows 1...a5 giving the king an escape square.

No computer could solve this because it is NOT possible.

3 moves, no less...

2 moves if rook takes pawn and black uses pawn to go for queen...then move the rook

Just for interest Fritz 11 suggest.

1. +- (#2) 1.d5xe6 c7xd6 2.Qf3xb7#

2.+- (#3) 1.Qf3-c3 a7-a6 2.Qc3xc7+ Kb8-a7 3.Qc7xb7

Though not the same as the given solution I think it's also right. Well done to silentfilmstar13.

we must thing about last black move

there is 1 possible move for black it's e5 ... it's mean white can take him " en passant "  via d5 pawn ....

How can I ( or the computer ) know what the last move by black was ? No wonder no computer can solve it
