Kibitzer's Corner
Premium Chessgames Member 23.Nxf6+ works just as well as 23.Rxf6, provided you intended on sacrificing the other piece next.
Dec-22-12  rilkefan: This looks relatively straightforward for a Saturday - 23.Nxf6+, Rxf6, Rxf6, and Qg5 bring the rook, queen and c3 bishop (with the diagonal open because else the e5 knight falls) into action against the king, which must be fatal, to say nothing of Bd5 or Be4. I guess 25...Re7 staves off mate, but then the knight does fall, and after say 26...Qe8 27.Qg5+ Rg7 28.Qxg7+ white ends up with a crushing endgame.
Dec-22-12  holy tramp: Varley- “I hate Miezes to pieces!”
Dec-22-12  M.Hassan: "Very Difficult"
White to play 23.?
Sides are equal

I have followed this line that although did not fully appeal to me but got results from it:

23.Bxe5 fxe5 (did not have time to analyze it if...Qxe5)

24.Be4 g6
25.Bxg6 hxg6
<if...exf4 26.Qxh7+ Kf8 27.Rxe4+ Bf6 Rxf6# or 27...Qxf4 to prevent mate>

26.Qxg6+ Kh8
27.Qh6+ Kg8
28.Qxe6+ Kh8
29.Rf5 Qd6
30.Rh5+ Kg7
31.Rf7+ Kg8
32.Nxe7+ Rxe7
33.Rxe7+ Qxe7
White is now a Rook+2 pawns up
Time to check

Dec-22-12  morfishine: White to move and instantly the focus is on <f6>, which is attacked 3-times but only defended twice; thus <f6> looks like a breakthrough point. This give us two candidates to look at: 23.Nxf6 & 23.Rxf6

*Black's only threat (besides Nxd3) is Qxg3 once his Knight clears

(1) <23.Nxf6+> 23.Nxe7+ Rxe7 and the rook lift helps Black defend

<23...gxf6 24.Rxf6 Bxf6 25.Rxf6> Double-attack on the Knight

<25...Nf7> 25...Ng6 26.Rxg6 hxg6 27.Qxg6+ and mate at <g7>

<26.Rxf7 Bxf7 27.Qg5+ Bg6 28.h5>

Something is missing here. I need to see if 23.Rxf6+ is more decisive:

2) <23.Rxf6> Direct attack on the WSB <23...gxf6> If at any point in the combination Black interpolates Bxd5, then White answers Bxd5+ followed by Bxe5

<24.Rxf6 Bxf6 25.Nxf6+ Kf8> 25...Kh8 26.Qxh7 mate <26.Bxe5>

Looks stronger than line #1, but I feel something is missing

Of course, don't bulldoze with both rooks, first one rook, then the Knight; I only considered two-options when there were three


PM: Extending line #2: 26...Qc8 27.Bd6+ Kg7 28.Qg5+ Kf7 29.Bf3 Rg8 30.Nxg8 Qxg8 that looks real good:

Dec-22-12  gofer: Well, its pretty easy to see that...

... Ne5 is beautifully placed to come in at f6 ( and if black decides to take Nd5 then we play Bxd5+ and win back our piece with tempo)...

... Bc3 is beautifully placed to attack Ne5 and is about to slice through black's defenses.

So what about our Rf4? Beautifully lined up but not really able to much due to the bishop pair on e7 and e6. Yep, he's are the cannon-fodder.

<23 Rxf6 ...>

23 ... Bxd5 24 Bxd5+ Kh8 25 Bxe5

23 ... g6 24 Qxe5 Qxe5 25 Bxe5

23 ... Bxf6 24 Nxf6+ gxf6 25 Rxf6 (transposes as below)

<23 ... gxf6>
<24 Nxf6+ Bxf6>
<25 Rxf6 ...>

I would say its all over, but there are still lots of options, the obvious one is...

<25 ... Bf7>
<26 Qg5+ Ng6>
<27 Rxg6+ hxg6>
<28 Bd5 Kf8>
<29 Bxf7 Re7>
<30 Bxg6 Qc7>
<31 Qh6+ Rg7>
<32 Qh8+ Ke7>
<33 Qxg7+>


Doh! Missed <27 Rxf7!> that would have made things much easier!

Dec-22-12  gofer: Crafty EGT

Dec-22-12  vinidivici: Wow this very good for saturday. Since a long time till find this nice saturday puzzle.

Believe it or not, my day is vacant. And i need about 25 minutes (yes 25 minutes) to find 23.Nxf6, all were tampered on my thought.

Dec-22-12  waustad: I figured out Nxf6 and a ways in, though as usual not all the way to the end. The bishops and rook looked like they could join in for the kill.
Dec-22-12  morfishine: <> Thanks for the heads-up: at least I was able to identify both candidates, only to misplay both :(
Dec-22-12  whiteshark: D'oh, I went for a double rooksac.
Dec-22-12  BOSTER: <gofer>
<Ne5 is beuatifully placed to come in at f6>.

I don't think so.

Dec-22-12  Patriot: This is very difficult. There are several really good candidates but the one that seems to have the most driving force is 23.Nxf6+.

23.Nxf6+ Bxf6 24.Rxf6 gxf6 25.Rxf6

So far the e4 knight is hanging and we've sacrificed a rook for 2 pawns. If the knight simply retreats to d7 doesn't that just defend and win? How about 26.Qg5+? Oh yes, 26...Kh8 27.Rf8#. The question is, "Is there a way to refute white's attack?" How about 25...Nf7? It's not very strong but defending could prove winning. 26.Rxf7 Bxf7 27.Qh6 Re5 28.Be4 Bg6 29.Bxg6 hxg6 30.Qxg6+ Kf8 31.Qf6+ Kg8 32.Bxe5 Qxe5 33.Qxe5 looks good. Another option for black is 25...Ng6. 26.Rxg6+ hxg6 27.Qxg6+ Kf8 28.Qg7#.

Now I need to back up since that seems to work. Could black have tried something like 24...g6? 25.Qxe5 Qxe5 26.Bxe5 puts white in good standing. Back up again... 23...gxf6 24.Rxf6 looks similar to a previous line but with the e7 bishop still intact. 24...Bf7 25.Rxf7 is winning. 24...Nd7 25.Qg5+ Kh8 26.Rf8# as before. 24...Ng6 25.Rxg6+ . 24...Nf3+ 25.Rxf3 .

I think this is about it unless I overlooked a defense. Not capturing the knight on f6 would be silly, not to mention deadly.

Dec-22-12  Patriot: Ok, I did miss a defense. In my main line after 25...Nf7, 26.Rxf7 Bxf7 is correct but 27.Qh6 is wrong because of 27...Qxg3. Correct is 27.Qg5+ Bg6 28.Qf6 .

Besides missing the game move, Houdini says both 23.Nxf6+ and 23.Rxf6 are very much winning so I don't feel so bad.

Dec-22-12  moppa: It's hard to have the disclipine to work through the variations when the breakthrough via f6 looks so obvious (given that this is a puzzle!)
Dec-22-12  Kikoman: <Nxf6+> and <Rxf6> are my candidates in todays' puzzle. :P
Dec-22-12  James D Flynn: Material is equal but White’s pieces are poised menacing the K-side. F6 looks like the weak point it is twice defended and 3 times attacked white must sac a R to win control of the square. It is probably best to start with a R sac immediately to pressure the B on e6 and tempt the Q to c8 to defend it when the R e7 square has to be defended . The N can remove one of the defenders by 23 Nxe7 Rxe7 but then the R defends the 7th rank and clears a path for the Black Q to defend her K. 23.Rxf6 gxf6 24.Rxf6 Bxf6 25.Nxf6+ Kf8 26.Bxe5(now White has sacked 2Rs for 2 minor pieces and 2 pawns, but both the Black Q and the R on e8 are attacked. If Black plays Qxe5 27.Qxe5 leaves White with and 2 minor pieces and 2 pawns versus 2Rs and one minor piece : more or less material equality but the exposed Black K should decide the issue in White’s favor. If the Black Q moves Qc8 27.Bd6+ Re7 28.Nxh7+ Kg7 29.Bxe7 wins a R and the Bkack K is in a mating net, therefore 26……Qd8 27.Nch7+ Ke7(not Kg8 28.Qg6#) 28.Bf6+ Kd7 29.Bxd8 K or Red8 30.Qxc5 with overwhelming material advantage and continued attack on the Black K
