I expected ...
... KxB after the first move. I guess it made no difference either way though.

Yes I know ...
I was just interested that the utterly hopeless move in the game was different to the utterly hopeless move that I'd have chosen. : )

Nice
I call this the box canyon mate. In the event that black takes the bishop and white's queen moves to h8 one piece is then attacking both g7,h6 and h7 and in this case the pawn protects the hidden pass. Silly I guess but then again I want to be a fireman when I grow up.

didn't like this one...
although black's move was irrelevant I'd expected KxB; 2. Qh8++
Any other move black did was totally out of place...

Pedrator I liked the puzzle but ...
.. I agree - although any move by Black after Bh6 is utterly hopeless, KxB would have been my choice. Odd really.

When you create a puzzle Gameknot fills out the last moves and there's no way to tell it to show one path or another as the main one. And what it maters is whether *you* figured out what would happen after Kxh6, not whether that move is played. After all I don't think you went "oh, I'll play Bh6 and hope he doesn't take my bishop!".

Good points Radus,
except that this is from a real game I think.

real game
offcourse there is a difference between a real game and a puzzle:
in the real game the opponent might stop the game afther Bh6.
In the puzzle you'll see the computer check all all possibilitiesafter the first move, and chooses ad random which move he made. Not the move in realiity is played, what so ever.

I just discovered...
... that doing this puzzle more than once, can give different moves. First thing this morning it went - Bh6, Bf3; Qg7 mate.
And just now, it went - Bh6, Qe8; Qg7 mate.

If this is from a real game, then why does it do that?

(And George2003, this one does   )

Yeh but like radus says
"When you create a puzzle Gameknot fills out the last moves and there's no way to tell it to show one path or another as the main one." It is from a real game but gameknots computer doesn´t know that. It doesn´t care what a "logical" move maybe because it can see that it is checkmate in 2 no matter what and doesn´t presume the opponent will make a mistake. After completing the puzzle it shows every possible move you could make as black, it chooses any one of them and you can´t instruct it to play the obvious one when you make the puzzle. If you do the puzzle a few times or hit reset after black make a move and start again you will see it randomly chooses where it wants to move. And like sjaak says there probably isn´t a second move after bh6 in a real game because most people would resign!

Thanks Sid
Yes I noticed the alternatives list, I just thought that "real games" would have all the moves entered. Interesting, cheers.
