White to move. How should white proceed?
Source: ChessToday.net
1. Nf6+ gxf6
2. Qg6+ Kh7
3. Bxf6….
Have a nice day.
1.Nf6+!
>A-1….Kh8.2.Qh7#
>B-1….gxf6.2.Qg6+!
>>B1-2….Bg7.3.exf6.Rxe1+.4.Rxe1.Qg4.5.Qxg4.and 6.Qxg7#
>>B2-2….Kh8.3.Bxf7!.threat Qg8#
>>>B21-3…Be7/d6/c5/b4/a3.4.Qxh6#
>>>B22-3…Qxf7.4.Qxf7.winning easily with Q +2P for 2 pieces and one more at least on the way. Black is busted.
>>>B23-3…Bg7.4.exf6. Threatening Qxg7#
>>>>B231-4….Rxe1.5.Qxg7#
>>>>B232-4…..Bxf6.5.Qxh6#
>>>>B233-4…..Bf8.5.Qg8#
>>>>B234-4…..Rg8.5.Bxg8
‘>>>>>B2341-5…Kxg8.6.Re7!.Qxe7.7.fxe7 and black is busted. White will get another Q or will have Q+R for 2B winning easily.
>>>>>B2342-5….Rxg8.6.Re7!.(to avoid mate at g7 black is forced to play ).Qxe7.7.fxe7! And black is busted as in B2341 above.

The e5 pawn should get a terrible speed here and set Re8 under deadly attack:
1. Nf6+! gxf6 (enforced)
2. e6!! Qc8 (fxe6 Bxe6+ gains Q)
The continuation shows that Qc8 seems needed to try keeping protection of e8.
3. exf7+ Kh8
With Q on c7 white should now have deadly Rxe8 Rxe8+ fxe8=Q. If Q was on e7 it should be taken by whites e file rook.
4. Qg6!
Threatens Qg8# and is the most direct approach here to continue attack on Re8.
4. … Bg7 (enforced)
5. fxe8=Q+ Rxe8
6. Rxe8+ Qxe8
7. Qxe8+
Up with queen.
White can go for mate and win some material, if Black defends:
1. Nf6+ gxf6 or concede the queen.
2. Qg6+ Kh8
2. … Bg7
3. exf6 Rg8
4. Re7 Qc8
5. Rxf7 Kh8
6. Rxg7 over and out
3. Bxf7 Bg7 Qg8# was threatening. The only other move to meet this was
3. … Qxf7
4. Qxf7 +- (Queen for two bishps, Bb7 hanging, f6 hanging)
4. exf6 Rg8
5. Re7 Qc8
5. … Qxe7
6. fxe7 Re8
7. Bxg8 Rxg8
8. e8=Q +-
6. Bxg8 Rxg8
7. fxg7+ Rxg7
8. Qxg7#
Shit, I wrote a good deal of nonsense again. Advancing e pawn to e6 is doomed to fail since black has Re8 to take on e6 with. The pawn is rather aiming at f6 eventually.
Keeping my first move, it obviously has to be:
1. Nf6+ gxf6 (Kh8 Nxd7 looses directly.)
2. Qg6+!!
The decisive move.
The f7 pawn is lovely pinned.
2. … Kh8 (Bg7? exf6 any Qxg7#)
3. Bxf7!
Threatens Qg8 mate, or Qxh6# if bishop leaves protection of it.
3. … Bg7 (what else?)
4. exf6 Rg8 (Bxf6? Qxh6#.)
5. fxg7+ (any better?) Rxg7
6. Qxh6+ Rh7
7. Qf6+ Rg7
If nothing else, white has far better pawn here. But I think 8. Re8+ looks good now…
I’m still not sure I found the most efficient line here, but this should at least be better than my first attempt…
Field day for white.
1.Nf6+ gxf6
No other go.Not because of attack on Q but because of mate threat at g7.
2.Qg6+ Kh8
No other go.2… Bg7 3.exf6
3.Bxf7 Bg7
No other go.4.Qg8# was threatened.
4.exf6 Rg8
No other go.
5.Bxg8 Rxg8
(5…. Kxg8 6.Re7 wins easily.)
(5…Bxf6 6.Qxf6+ Kxg8 7.Re7)
6.Re7 Qxe7
7.fxe7 wins
I ponder…
A possible improvement could perhaps be:
1. Rd1!? Qc7
2. Nf6+ gxf6 (Kh8 Qh7#)
3. Qg6+ Kh8
4. Bxf7 Bg7
5. exf6 Rg8
6. fxg7+ Rxg7
7. Qxh6+ Rh7
8. Qf6+ Rg7/Kh7
9. Rxd8!
Being up with a rook and there is a threat on h8.
1.Nf6+ gxf6 2.Qg6+ Kh8 (2.-Bg7 3.exf6 +-) 3.Bxf7 (threatens Qg8++) Bg7 (3.-Ba3 4.Qxh6++) 4.exf6 +-
After posting the first,I got some new ideas.
1.Nf6+ gxf6
2.Qg6+ Kh8
3.Bxf7 Bg7
4.exf6 Rg8
5.Re3
Intending 6.fxg7+ Rxg7 7.Qxh6+ Rh7 8.Qf6+ Rg7 9.Rh3+ when black has to give up Q. It also prevents ….Qd3
5…. c5!
Now the above plan is not fruitful because of pin on g2 P.Because of this I had given it up before posting the first comment.But now
6.Rg3 Now black has nothing else but 6… Qxf7 giving up Q.
Dear fajac,
(In good humour)
Aristotle Principle ” No two objects can occupy the same space at the same time”(Principle in Physics).
Chess principle:”You can not kill your own men”.Your 3… Qg8 (fifth line) violates one of the two principles as black K is there already.
I should certainly withdraw my “improvement” 1. Rd1??
It fails to 1. … Qe7, forbidding 2. Nf6+? gxf6 3. Qg6 Bg7! 4. exf6? Qxf6!
It seems that the first 4 moves of this puzzle are quite enforced:
1.Nf6+ gxf6
2.Qg6+ Kh8
3.Bxf7 Bg7
4.exf6 Rg8
From here white seems to have more options and a good deal of thinking is needed.
I am instinctively doubtful though to the idea:
“5.Re3
Intending 6.fxg7+ Rxg7 7.Qxh6+ Rh7 8.Qf6+ Rg7 9.Rh3+ when black has to give up Q. It also prevents ….Qd3″
Here I should say that it looks needed to omit such indirect move as 5. Re3 and instead proceed directly to the enforced looking line:
5. fxg7+ Rxg7
6. Qxh6+ Rh7
7. Qf6+ Rg7
and here I think 8. Re7 looks quite good.
When playing 5. Re3 first, with a threat laying so far ahead, my experience says that the opponent will probably use his extra tempo to find something really nasty!
What to be said about:
5. Re3? Qd6!!
Q is still protected by Rd8, and the intention is to exchange queens.
6. Rg3 Qxf6!!
Dear phd,
thank you for the new idea which I had not thought of.
After,
5.Re3 Qd6
6.fxg7+ Rxg7
Now I can not definitely take 7.Qxh6+ but however,
7.Re8+ Rxe8
8.Qxd6 Rxf7 black gets a respectable R & B for Q.
Wait,there is something better.
6.Bxg8 intending 7.Qh7#
6…. Rxg8
7.fxg7+ Rxg7
Now 8.Qxd6 is pea nuts.
8.Re8+ Rg8
9.Rxg8# of course you can extend by one move by 8…. Qf8
Why 9.Rxg8# and not 9.Qxg8# ?
The work should be executed by the lowest cadre possible. In addition white Q wants to observe the colors on black Q’s face at the time of execution.In addition I want to capture black Q after mate is executed.
Surprisingly on 2 occasions capturing Q is irrelevant in this problem.
(1)1.Nf6+ Here Q is also attacked but it is irrelevant as mate is threatened.
(2)5… Qd6 (refer to phd above.)6.Bxg8+ Rxg8 7.fxg7+ Rxg7 and now 8.Qxd6 is irrelevant.
Dear phd
UNTOLD STORY
I had some problem in delaying Re3.
I tried your move.Of course it was my move also but I had assumed … QxR by black.
8.Re7 Qd6
Strong but not fatal.
9.Qxd6
9.Re8+ leads to Q vs R and B.
9… Rxd6
10.Rxb7 gets B free but there is pin on B.
10… Kh7 to avoid R check.
11.Re1 Rf6
12.Re7 Rxf4
13.kg1 and white is safe and can remove B.I am too lazy and hasty.After seeing pin on B I abandoned it.but 8.Re3 is fatal because of ….. Qxf7.
After all this I adhere to my first posting giving least leeway to black.
