Black to move. Which side is better? How should Black proceed?
1. Qe4+
2.Kxg5 Nf7+
3.Kf6 Qh4+
And the White king will be mated on g8
If 3.Kg6 then Black shld play f4+ and the White King will be mated on g8.
In the line
1. … Qe4+ 2. Kxg5 Nf7+ 3. Kg6 f4+ 4. Kg7,
how will the wK be mated on g8? (This was the only place I got stuck during my own analysis.)
Qe4+ Kxg5
Nf7+ Kf6
Qh4+ Kg6
Qg5+ Kh7
Qh6+ Kg8
Ke7++
wolverine
Qe4+ Kxg5
Nf7+ Kg6
Qg4+ Kh7
Qxh5+ Kg7
Qh6+ Kg8
Ke7++
wolverine
Qg4+ ? with a pawn in h3 (hxQg4) ?.
Qe4+ Kxg5
Nf7+ Kg6
Qg2+ Kh7
Qxh5+ Kg7
Qh6+ Kg8
Ke7++
i meant Qg2
wolverine
I see a completely opened king. I directly go for the …Qe4+ variation:
1…Qe4+
2.Kxg5 Nf7+
3.Kg6 f4+
4.Kg7 Qg2+
5.Kh7 Qe4+
6.Kg7 Qg2+ (I don’t see anything better than draw by repetition)
White could play worse:
3.Kf6? Qh4+ 4.Kg7 Qg5+ 5.Kh7 Qh6+ 6.Kg8 Ke7# (a wonderful discovered mate given by the king…)
or
4.Kf6? Qf5+ 5.Kg7 Qg5+ 6.Kh7 Qh6+ 7.Kg8 Ke7# (a king hunt; again with the great discovered mate!)
Only after going through all these variations I checked for other moves…but didn’t find anything.
My thinking process was very bad: Directly going for one variation and calculate it all over. I know I should first analyse position, then find candidate moves and son on…
Have a nice day
actually theres no mate along this line of play. its a draw
Qe4+ Kxg5
Nf7+ Kg6
f4 Kg7
Qg2+ Kh7
wolverine
The line I’m considering is
1… Rg4+
I think black wins in all variations though I don’t have time to write them out.
3…Rg4+
4. hxR Qe4+
5. Kg3 Qg4+
6. Kh2 Nf3+
7. Kh1 Qh3 Mate
3…Rg4+
4. Kxe5 Qe4+
5. Kf6 Rg8 (threatens Rf8+ followed by Qg2+)
3…Rg4+
4. hxR Qe4+
5. Kg5 Qxg4+
6. Kf6 Nf7 (threatens Qg5 mate. Can be stopped with Rg1:
7. Rg1 Qxg1
8.Kg3 Qxf2 (and black should win…)
Okay, I hope I got it right. 🙂
To XY 1….Rg4+
2.hxg4
Your move
XY sorry you where just faster
Now:
3…Rg4+
4. hxR Qe4+
5. Kg5 Qxg4+
6. Kf6 Nf7 (threatens mate, but I have intermediate checks)
7.Ng7+ Kf8
8.Nxe6+ Kg8
7.Ke7 (I think now my king is safe…)
What a sharp and good line you found anyway
Kudos
Have a nice day
Okay Jean-Luc, you’re right, that check is a pain in the neck. However, I have a fix, I think, reversing the order of the moves:
3…Rg4+
4. hxR Qe4+
5. Kg5 Nf7+
White now has two alternatives: Kf6 and Kg6. Black just keeps checking: Qg4+ (on Kg6) or Qh4+ (on Kf6), then Qg5+ or Qxh5+ depending on black’s move. It looks over for white. But it’s all in my head, so I’m not certain.
I wrote: “…then Qg5+ or Qxh5+ depending on black’s move…” Obviously, it should be “…on whites move…” (not black). Sorry.
Not sure but I think you just overlooked another pain in the neck: After 4.hxR this pawn stops Qh4+…it stands on g4
3…Rg4+
4. hxR Qe4+
5. Kg5 Nf7+
6.Kf6 you could play Qxg4
7.Ng7+ (aaaarghhh)
What’s needed to make this variation work is so thin…It’s not fair!
Oh noes. How about this, you create a distraction and I put the Knight on h5 in my pocket.
I have gone through all the lines above with interest; what baffled me was in many of the lines where Black Queen checked on g2 the continuation given was Kf6?? . Why not the Simple Interfering Ng3!?; Secondly in the Qe4+lines… I fail to see mate after …Nf7+ and Kg6! as correctly pointed out by some.
The Solution strangely is strikingly simple
The Quiet
1…Rxh5! wins in all variations; the immediate threat is Qe4+ with mating threats along the Light squares
2. Rd5!? A tricky move
(2.Kxe5 Qe4+ 3. Kf6 Rh6+! 4. Kg7 Qh4 5 Rg1 Rh7+ 6. Kg8 Ke7 Mate)
(2. Kg3 Qf3+ with rapid mate)
(2.Qc2 Qf3+ 3 Kxe5 f4+! 4. Kf6 ef+ 5. Kg7 Qf7 Mate)
2…Ng6+! ( Black correctly avoids 2….exd5? Qxe5+)
3. Kg3 exd5
And with White’s bad King due to open diagonal(a8-h1) and g and h files Black should ultimately win… although some care should be take about counter play on the h8-a1 diagonal.
For Instance
4.Qf6 can be met by
4…Qc6

King.
How about replying to 1…Rxh5 with 2. Qxe5
@King
1…Rxh5! you didnt consider 2. Qxe5 and black is losing!
I couldnt find a winning line for black 🙁
Yes… you are right. Pardon me for my gross blunder. I did consider Qxe5 in my mind but thought Qf3 was Mate… lol . Thanks for pointing it out, keeps me on my toes, I’ll have to double check my analysis next time. Although Alexander Kotov (Author of Think like GM) does not recommend it; But since I hallucinate frequently I guess I have to make some exceptions. Nevertheless I love the challenge of seeing how far I can analyze efficiently without blunders, it helps me improve. Thanks again.
My Regards
King.
1…Qe4+
2. Kg5 Nf7+
3. Kg6
Then black gets stuck.
(1) 3…f4+ 4. Kg7
(2) 3…Qg2+ 4. Ng3 (or 4. Kh7)
Conclusion: black is losing at this position.
I think I found an interesting line:
1…Rg4+
2. hxg4 Qe4+
3. Kg5 Nf7
4. Ng7+ Kf8
5. Nxe6+ Kg8! and black wins as it is threatening mate with Qh4+ followed by Qh7mate and if 6.Nxd8 Qg5 is mate
unless I missed something, which is possible
I forgot to put the moves Qxg4+ and Kf6 on my line, sorry about that
