RE: Chess problem 64 / Schachaufgabe 64

[ralk98]

Hello @jaki01 , I could find this:

#1

1)Ng6+ Nxg6

If hxg6 (Rh8 #) or If Fxg6 (F7+ Kh8 + Rxh7 + Nxh7 +F8 queen #)

2)Rxh7+ Gxf6
3)Rxf7+C5
4)Rh7+
any other other move leads to RfG2 #

#2

1)G2+ G6
2)Nxg6+ hxg6
3)Th8+ Kxh8 (forced)
4)Kxf8+C5
5)Rh2#

---

This is all, my brain is cluttered and I need to sleep. I give up!

First of all: I don't understand your #2: 1. g2+ is an impossible move.

Concerning #1:

1. Ng6 (it's no check, "+", by the way) Nxg6
2. Rxh7 gxf6
3. Rxf7 c5
4. Rhh7

Now you mean that white will win with Rfg7# (not Rfg2)?

What will you play after:

1. Ng6 Nxg6
2. Rxh7 gxf6
3. Rxf7 Nf4?

What will you play after:

1. Ng6 gxh6?

How about:

1.Ng6

a)1...hxg6 2.Rh8#
b)1...fxg6 2.f7+ Kh8 3.Rh7+Kxh7 4.f8R or Q#
c)1...Nxg6 2.Rxh7 gxf6 3.Rxf7
c1) 3....c5 4.Rhh7 and white will mate with Rfg7
c2) 3....Nf4 4.Rg3+ Kh8 5.Rxf6 Kh7 6.Kf7! Nh5 7. Rh3 and mate next move with 8. Rxh7.
d)1....gxh6 2.Ne7+ Kh8 3.Kxf8! c5 4.Rg3 Qg2 5.Rxg2 and mate next move with Rg8.

[jaki01]

... and mate next move with 8. Rxh7.

You mean with 8. Rxh5? :)

d)1....gxh6 2.Ne7+ Kh8 3.Kxf8! c5 4.Rg3 Qg2 5.Rxg2 and mate next move with Rg8.

1. ... h5 4. Rg3 h6, and now?

[iceblue]

.. and mate next move with 8. Rxh7.

You mean with 8. Rxh5? :)

Yes, I meant 8.Rxh5. Damned clerical errors :-)

d)1....gxh6 2.Ne7+ Kh8 3.Kxf8! c5 4.Rg3 Qg2 5.Rxg2 and mate next move with Rg8.

... h5 4. Rg3 h6, and now?

4.Kxf7 followed by 5.Ng6+, 6.Nf8+ and 7. Rg8 mate.

[jaki01]

You mean 5. Kxf7. :-)

Right, or also 5. Rg8+ Kh7 6. Rg7+ Kh8 7. Kxf7 and then 8. Ng6#. :)

[iceblue]

Yes, 5. Kf7 :-). I had it that way but corrected it ...it is too hot :_)

[jaki01]

That's clearly enough to deserve a little upvote. :)
