1. Nh3! with a threat of Nf2+ mate!

Black can play …

1. … e3

2. Nxg5 and the g-pawn should queen

1. … Rf5+

2. Rf4! and black can’t stop white’s g-pawn from queening.

Nh3 threatens Nf2 mate and if RxN then RxR mate; …Rf5+ Ke1, Rg2 preventing Queen then Nf2 discovered check followed by Rh1 mate; Rf5+ Ke1 RxN RxR+ and Queens

1.Nh3 is inconvenient, threat: Nf2++, so

1. … Rf5+

2. Rf4 and Black is in a world of hurt.

nh3 => nf2

han

1.Nh3 is best for white. If black tries to take 1…Rxh3, then white mates in one, 2.Rxh3. If black moves 1…Rgxg7, then white mates next move, 2.Nf2#, the black rook at h2 is pinned by the white rook along the h-column.

I guess it’s 1.Nh3 Rf5 2.Rf4!

1.Nh3

a) 1…Rxh3

2.Rxh3#

b) 1…Rxg7

2.Nf2#

c) 1…Rf5+

2.Ke1

now, black can’t stop white from queening…

d) 1…e3

2.Nxg5

and white’s g pawn can’t be stopped…

Nh3 (threat Nf2#) wins or promotes.

White wins this game with the simple:

1. Nh3!!

threatening 2. Nf2#. Black now cannot prevent both this mate and the promotion of the g-pawn.

1… Rxh3 2. Rxh3# is immediate mate, while 1… Rgg2 2. g8Q Rxg8 3. Nf2# (or 2… Rf2+ 3. Nxf2#, or 2… Rxf3 3. Qxg2#) stretches it by 2 moves.

1… e6 2. Nxg5 and now black cannot stop the g-pawn from promoting.

I think the best response for black is 1… Rf5+. Though I still see only

2. Ke1 Rg2

3. Nf2+ Kg1

4. Rh1#

Update: Here, 2… Kg2 3. g8Q+ Kf3 4. Ng1+ Ke3 5. Rxh2 seems to allow black to escape albeit with significant material disadvantage.

1.Nh3 (Rxh3 2. Rxh3#)

Rf5+

2.Rf4 (Rxh3 3.Rxf5 Rg3 4. Rh5#)

Rxf4

3.Nxf4 ..

4.g5=Q

1. Nh3

David

1. Nh3 seems fine. threating Nf2#

black should give its g-file rook.

1.Nh3 Rxg7?? 2.Nf2#

1.Nh3 Rf5+ 2.Rf4 Rxf4 3.Nxf4 1-0

Nh3 1-0

1. Nh3 threatens Nf2# and also attacks the Rg5. Black’s only move is 1…Rf5+ 2. Ke1 but now g8Q is unstoppable. The ending will still be very difficult, though.

One possible line is 2…R:h3 3. R:h3+ Kg2 4. g8Q+ K:h3 and White faces a long struggle.

NH3

Nh3 looks promising.

If 1…Rxg7, then 2.Nf2#

If 1…Rxh2, then 2.Nxg5 the pawn queens.

1. Ng3 looks like is the winning move for white.

1. Nh3!

1.Nh3 ! +-

if 1…. Rxg7

2.Nf2++

if 1…. R5g2

2.g8=Q +-

if 1…. Rxh3

2.Rxh3++

if 1…. Rf5+

2.Ke1 +~

if 1…. e3

2.Nxg5 Rxh4

3.g8=Q +-

if 1…. other

2.Nf2++

Xargon the true

nh3 threatening nf2 mate

I think I have found the correct solution in the first

few moves, that’s the good news. The bad news, is that

if it is the correct line, then actually winning

from that point on is going to be exceedingly difficult, at

least for me, since queen versus rook endings with no pawns

is very hard, and playing with a lone queen

against a rook and one or two pawns, let alone

THREE pawns, is just about absolutely impossible (for me).

I’ve even seen games where GRANDMASTERS have not won queen

and rook endings with NO pawns on the board. I find queen

versus rook to be more difficult than bishop and knight

versus lone king.

So here goes:

1. Nh3 (threat is 2. Nf2#)

(It would be nice to be able to play 1. Nf3 threatening

2. Rxh2#, and 1…. Rxh4 loses to 2. Nxh5, but the simple

1…. exf3 wins for Black.)

1…. Rf5+ (the only good try)

2. Ke1 (a sad necessity. I wanted to play 2. Rf4,

when 2…. Rxf4+ Nxf4 wins for White, and

2…. Rxh3 3. Rxf5 Rg3?? (to stop the

pawn) 4. Rh5+ Rh3 5. Rxh3#. But Black

has 2…. Rg2, which drops a rook, but

3. Rxf5 Rxg7 draws, I think.)

From this point, I think there are 2 reasonable defenses for

Black: 2… Rxh3 and 2…. Rf3. They both lead to the

theoretical won queen versus rook and 3 pawn endings which

I dread. What doesn’t work for Black at all on the 2nd move

are any moves by the rook along the 2nd rank. Any move

of the rook on the 2nd rank, except 2…. Re2+, leads to a

devastating double check, 3. Nf2+.

2…. Rxh3

3. Rxh3+ Kg2

4. g8=Q+ Kxh3

5. Qg6 (Preventing 5…. Kg4, and better than

5. Qc8, I think, since after

5…. Kg4, I don’t see any way for

White to pick up the d-pawn, which

has to be the first to go. White

has to deal with the at least one

of the advanced connected passed pawns

first.)

5…. Rf3 (probably)

Here White can win the d-pawn with 6. Qh5+, but this

may be too hasty. This is an exceedingly difficult

ending from this point on, and I’m not going to go

there tonight.

The other try for Black on move 2 is 2…. Rf3, and

again, it leads to one of those dreaded, theoretically

won endings:

2… Rf3

3. Nf2+ Rxf2 (with the only legal rook)

4. Rxh2+ Rxh2

5. g8=Q

and here the d-pawn goes quickly, but as I said before,

it’s going to be a long time before White wins this one.

My insomnia woke me up to work on this problem tonight, but

it’s time to go back to sleep. And I hope that I’m not

going to be dreaming about queens and rooks and pawns.

What a nightmare.

An unusual end game requires a bold and unusual move. How about 1. Nh3, threatening 2. Nf2#? If 1…e3 to counter Nf2, then Nxg5 and the pawn queens. Other moves have similar outcomes.

Sorry about the repeats. I can explain. Every time I clicked on “PUBLISH”, I got a message saying that I had exceeded the limit of the amount of URI text I was allowed to enter. So I thought each time that I needed to try again.

As I believe in democracy, and there is a 100% vote for Nh3, I will go for Nh3 as the winning move.

I looked at 1. Nh3 Rf5+ 2. Rf4 and concluded it wasn’t as good as 2. Ke1. Here’s why. Black can play 2…Rg2 3. R:f5 R:g7 and the ending most likely will reduce to R+N vs. R+a-pawn. This is a very difficult ending. I stand behind Lucymarie’s repetitive comment – 1. Nh3 Rf5+ 2. Ke1 leads to a difficult ending with Q vs. R+ pawns.

I believe white can win this, the basic drawing resource for the side with R+P is to have a P on the 2nd rank defending the R, which keeps the K out while the K just hides behind the pawn as permitted. That’s not possible here.
