Why can't it be 5. Kxd7 ? Why is it Kc8??
Very good! Very useful!
If 5. ... Kxd7, then 6. Bb5 Kc8, 7. Re8# -- still mate in 7!
...dont' like passing up multiple other mates to find some obscure 7th one..
What multiple other mates??
If the aim is to checkmate the black King (is it not?) The proper sequence is:
1. Bishop eE6 check 1.K b8
2. Queen takes Queen a4 checkmate
You need to spend some time reading all of the above post. Something that may be beneficial for you would be to study basic mating patterns and defense of these same patterns. But in order to defend you must 1st see the whole board and look for moves that may thwart your ideas.
In the above case as soon as you find your 1st move for white: 1. B36+...before you make that move you must survey the board for 4 things: 1. Can the Black King move away from the check (if so you must find the best square for black w/o making you 1st move), 2. Can the Black King take the checking piece (if so will taking the piece help or hurt your position? Once again this must be done before making your 1st move), 3. Can the Black pieces block the checking piece (if so you must survey to see if more than one piece can block and find out which blocking piece best improves your position and which hurts your position so you are preparred for a follow-up. Once again all this is doe before your 1st move is made), 4. Can the Black pieces take the checking piece (if so will this help or hurt your position and do you have a follow-up move if it does take.)
Now that you've done these things you must see that the King is not forced to move because the Black Bishop at h3 is going to play 1. ... Bxe6! which greatly hurts your position. This stops your mating threat in its tracks. And when this discovery is made...you must begin looking for a different 1st move going through the same processes above.
Good luck in future analysis.
Thanks! I missed B x E6. This will help me not to be hasty.
The bishop can take the bishop if be6+!!!!!!!!
wow!!!! i solved it by accident on my first go!!! :D
So did I, but the first move really was hard to see.
Taking the rook on d7 would also be mate in 7, but not as pretty as this one =D
Very nice puzzle, made only one mistake (queen takes rook)
it is stupid one why the hell the queen doesnt beat rock for the first time...
