exd4 is not forced.
Black can play other moves to prevent mate.
Great Puzzle! :D
WHY does the bishop not take the rook? Perhaps I am thick!
Because then White can force mate.
Yeah, don't see why really. 4.Qxh7# and it's over. But the Rf6 was brilliant, I would never have guessed.
If you try to mate, you will see that Black has the f7-f5 move. Then you have to find a way to stop this move and the only way is, to block this pawn. Step by step you'll find moves like Rf6.
Ooh that second move was a doozy.
It was hard for me to calculate what black's defensive resources against the pawn advance actually were, but it makes perfect sense now I see it.
Was black forced to re-capture on the first move?
(Edit: ok I see that it wasn't. Since that's the only reason why I didn't play it (assuming black would try to prevent the pawn from moving), I'm happy. :D
What a neat series of threats, though.)
why not 4.Qxh7# ?!
not an easy one..
why not p to F6 when white bishop took knight. This would have exposed the white queen and white would have either had to take the black queen or lose the white bishop.
White would have the advantage but it would not have led to a quick mate.
Benkő Pál qualified for the 1970 Interzonal tournament, the leaders of which advance to the Candidates. However, he gave up his spot in the Interzonal to Fischer, who went on to win the World Championship in 1972.
Very high standard puzzle.
Another big blow by Fischer... so good.
