could be longer!

there is many moves that black can make which will result in a longer game. Not a very good puzzle.

re:could be longer

Another day, another puzzle where somebody claims the solution is wrong.
And i've got that same old feeling that they're wrong

Great puzzle. Qb1 is the only move that covers the knight on f5 and can trap and checkmate the black king should he move to g8.

I'm not sure how you guys are using the term 'elegant'. Once you realize the potential problem of the unprotected knight and the king's escape square at h7, the solution is simple. It's all about grasping what is really going on within this puzzle. I certainly do not find this puzzle crude in any way.

Elegance in a chess puzzle

I about the magic. This is straight forward - you work out that there are "must" move (protect the knight, cover against black king to h7 or g8, and work out the ony possible move. Mathematics replacing magic

Agree with you EDGE!!!! How many times do we have people claiming the solution is incorrect etc etc etc. Maybe GK need to have the 'options' menu and 'another solution' in a bigger typeface with a flashing arrow and a text saying 'please try this before telling us the puzzle composer got it wrong' !

The Problem I have

The problem I have with puzzles like these is that they are unrealistic. Two knights, one bishop, one, queen, and one pawn about to become a queen all against one king....and your opponent has not resigned!!?? I mean its okay for practice, but I prefer puzzles that one might be more likely to encounter.

RE:could be longer ; RE:Difficult, yes

All possible scenarios considered:

1.Qb1
1...Ke8 2.g8=Q#
...Ke6 2.g8=Q/B# (VERY "elegant" use of the diagonals)
...Kf6 2.g8=Q#
...Kg6 2.g8=Q#
...Kg8 2.Nh6# (as hypersyne mentioned earlier, moving the knight opens the queen's diagonal to discover h7!)
---
Considering how black only has his king left, you can't really say there are "many moves" that he/she could make.
I will, however, say that there is almost no need to care about mate in 2, as white could have either delivered checkmate long before this position was reached, or a much easier mate in 3 could occur (not accounting for the 50-move stalemate rule).

"there is many moves that black can make which will result in a longer game. Not a very good puzzle. "

Haha, incorrect my friend. So, I'm white, you're black, I play 1. Qb1, what say you sir?

I found Qb1 moving the queen randomly in my mind. It's not the correct way to find out a check mate...
