I can't solve it, maybe someone else can? Possibly it's very easy but I don't see something :)
The puzzle is:
White has a king, a knight and a pawn. Black has a king and a queen. Set up such a position, that white wins even though it's black to move and the black king is not checked.
Note: even if white manages to promote, KQN vs KQ is usually a draw.
Rating 2396 and you can't solve this simple puzzle?!
Give the answer then Borg.
2396? That's bullet, it doesn't count :)
I guess I'm missing something simple
Tried for a bit, very tough because of drawing resources. I'm having trouble making a position with 2 threats where there's no stalemate or drawn pawn endgame.
So I don't think it's too simple because the queen can often sac itself for either piece to make a draw pretty easily.
Hahaha! I was just teasing Kacparov here, I have no idea how to solve it :-p
When you do find the answer, please post it!
I think I might be able to solve this with endgame tablebases, just by myself would probably be too hard
Good luck! I found it impossible to avoid a win by the queen-side let alone stopping draws and having the knight side win! I only gave it 20 minutes though.
Yeah, that'd be pretty easy, just look through the 7 million different combinations of 5 pieces on 64 squares and you'll have it in no time!
And hey, because of mirror positions and possibly more than 1 solution, you may have only 1 or 2 million to look through. Good luck.
I kept trying to make this type of thing work, but I decided it can't and has to be something else :)
Threatens two different mates, lookin good?
But there are too many checks on the 6th rank, the most annoying is just Qf6+ because of the stalemate.
Queen close to same rank or file as king eliminates lots of checks. I also tried to use knight as fodder to hamper the queen. But in those cases couldn't set up a threatening enough position.
I tried similar positions, there's just no way I could find to stop checks that lead to either a draw or win for the queen-side.
Wow wafflemaster, ? What I obviously meant is that there may be a line where white can queen that is a winning KQN vs KQ. Looking at all such positions (the KQN vs KQ that can arise) and seeing whether they are a win or a draw would be too much for me.
I still don't know the answer. There is one more idea (on the diagram), but black manages to save by Qe7+! or Qe8+! and then Kg7. Maybe it can be changed somehow so there is no Kg7 possibility.
edit: fortunately that doesn't really help any, either
It may be able to give the answer
That's closer than I got Kacparov, still no cigar tho! :-)
And still no solution ?
E mail one of the IMs or GMs on here, and ask them.
That was my idea too, but I was too lazy to go look up in one of my endgame books to learn when Q+N can beat Q and then try to come up with some clever way to force that position.
That would be a good way to approach the problem though.
(And putting random positions in an EGTB may take a long time).
If white first to move then Nf7 is mate. If not then draw
