RE: Chess problem 47 / Schachaufgabe 47

in #chess7 years ago (edited)
  1. Kf8 Ne8 2.f6 and black is in zugzwang, black cannot move his knight because it is the only piece that defend the checkmate. If black plays:
    2... a6 3. bxa6 bxa6 4. c6
    2... b6 3. cxb6 (or axb6) cxb6 (axb6) 4. a6 (or c6) and White is going to crown a queen
    Other variant could be:
  2. Kf8 Nxf5 2.Qf6 and black has the same problems that in the first variant.

I like this kind of position, they teach you so much

Sort:  

Looks great. I think in the second variation you mean 1. Kf8 Nxf5 2. Qf6, right?
This time we have a quiet solution which you found and a more spectacular attack which @greatwolf found, but still didn't show me the final position. :)

Edit: as @greatwolf pointed out, after 1. Kf8 f6 black wins (check my reply to his last comment here).
Nevertheless you did very well, too: your idea tricked me so that I suddenly thought my problem had a second solution. Sorry for the confusion caused, next time I should be more thoroughly again!

I have to ask, what happens if black just plays f6 instead after Kf8?

@greatwolf, you saved my chess problem!
Actually when I composed it I only had one solution in mind, the one which you found! And yes, I thought I had checked it well enough. However, when @juanmi96 posted his idea, I suddenly thought "Damn, there is a second solution, but I have to accept that, and it looks nice, too!"
(I didn't check it thoroughly enough to verify it before I declared his solution as 'correct', too, neither by 'biobrain' nor by chess software - sorry for the confusion caused. :-) )
But you are completely right: After 1.Kf8 f6 black wins, and to be honest, I am happy that my little chess problem has one solution only ...

Yes, you are right Nxf5, sorry.

  1. Kf8 Nxf5 2. Qf6 a6 3. bxa6 bxa6 4. c6 Qg4 5. hxg4 a3 6. gxf6 a2 7. Qg7++
    4. ... Qxg5 5. fxg5 Ng3 6. Qg7++
    4. ... Qh6 5. gxh6 Kxh6 6. Qxh8+ Bh7 7. Qf6 Bg8 8. Kxg8 Ne7+ 9. Kf8 Nf6 10. Qh8++

Your notation doesn't make any sense after move 4. do you mean hxg, h3? Also what is axf6??
