Jun-05-15  morfishine: The initial move wasn't too hard to settle on <22.Rxf7> and after 22..Kxf7 23.Qh5+ Kg8 I was thrilled to find <24.Nd5>

<Once> I figured the “main line” was 24...exd5; Surely, there must be something better than 24...Bf8

Stop calling me Shirley :)

Jun-05-15  Cybe: White could play R:f7 at 21st move: 21. R:f7, 21... K:f7, 22. N:c5, 22... bc (dc/R:c5), 23. Qh5+. Why Black has played 20. Nc5? They could, for example, 20. B:g5, however after 21... B:g5, 22. N:b3, 22... R:f7!
Jun-05-15  Nick46: Hey, Shirley, I wonder, is there perhaps some abstruse symbolism hidden in White's surname Tischbierek (which in English translates as Table-beer-corner) hummmm?

  MJCB: What happens on 26 ♘f6 ? . It seems to me that the bishop attacks the black queen while simultaneously the white queen threatens mate. Isn't it a quicker way to win? Or did I miss (again) something?
Jun-05-15  fokers13: very easy compared to the previous days.got all the way up to Qf7 since by that time i was convinced white was winning
Jun-05-15  Abdel Irada: <It's not nothing to do with chess>

You mean it ain't not not to do with chess?

Jun-05-15  Lambda: I actually saw the idea of Nd5 clearly, but for some reason after 22.Rxf7 Kxf7 the only check I could see was 23.Qf3+ (or Qf1+), (probably somewhat drawn by putting the queen on the same diagonal as the Ra8), after which it doesn't work.
Jun-05-15  mistreaver: Friday. White to play. 22.? Difficult?
I like the exchange sacrifice on f7 very much.
22 Rxf7! Kxf7
23 Qh5+ Kg8
And now
24 Nd5 exd5
25 Be6+ Kh8
26 g6 h6
27 Bxh6
and white gets at the king
If instead
23... Kf8
24 Rf1 is the killer
Time to check.
-----------------
Hmm yes that is it.
Jun-05-15  dfcx: I tried 22.Rxf7 Kxf7 23.Qf3+ Kg8 and 24.Nd5 is not working.

Did not see 23. Qh5+!

  kevin86: The rook for piece sac sets the whole thing up. Too bad 4 me, this is above ny pay grade...lol

  Mating Net: <What is wrong with 22.Bc5?> A very valid point and a move that has to be considered first. I suspect it was rejected because if White captures the Rook, Black gets a stranglehold on the dark squares after ...Qxc5+ and ...Bxg5. This is most likely the reason why Black played the exchange sac with 22...Rxc5, he wanted his Rook to get captured to gain the dark square domination.

By capturing the Bishop f7, White gets an analogous position by dominating the light squares in Black's camp.

  thegoodanarchist: 22. Rxf7 was obvious. The tricky part was the interference sac with the knight on move 24.

  agb2002: The material is identical.

White can win the exchange with 22.Bxc5 but after 22... Qxc5+ 23.Kh1 Bxg5 and Black owns the dark squares.

Another idea is 22.Rxf7 Kxf7 23.Bf1 but the queen can move to b4.

The attempt to exploit the defenseless rook on a8 with 22.e5 dxe5 23.Rxf7 Kxf7 24.Qf3+ is met with 22... Rxe5 23.Rxf7 Kxf7 24.Qf3+ Kg6 25.Qxa8 Rxe3.

Another possibility is 22.Nd5:

A) 22... exd5 23.Rxf7

A.1) 23... Kxf7 24.Qh5+

A.1.a) 24... Kg8 25.Be6+ Kh8 (25... Kf8 26.Qf7#) 26.g6 h6 27.Bxh6 Qe2 (27... gxh6 28.Qxh6#) 28.Qh3 (or 28.Qxe2 gxh6 29.b4 wins decisive material) and the discovered check looks winning.

A.1.b) 24... Kf8 25.Be6 g6 26.Qxh7 Ke8 27.Qg8+ Bf8 28.Qf7+ Kd8 29.Qd7#.

A.1.c) 24... g6 25.Qxh7+ Ke8 (25... Kf8 26.Be6 transposes to A.1.b) 26.Qg8+ Bf8 27.Qxg6+ Kd8 (27... Ke7 28.Qe6+ Kd8 29.Qd7#) 28.Qf7 Be7 (28... Ra7 29.Qxf8+ Kc7 30.Qc8#; 28... Rc7 29.Qxf8#) 29.Qg8+ Kc7 30.Qxa8 b5 31.Qc8+ Kb6 32.Bxc5+ wins decisive material.

A.2) 23... Qxe4 24.Bxc5

A.2.a) 24... Kxf7 25.Bg2 followed by 26.Qxd5+ and Qxa8 wins.

A.2.b) 24... b(d)xc5 25.Rxe7 Qxe7 26.Qxd5+ followed by 27.Qxa8+ wins.

A.3) 23... Re8 24.Be6 looks very bad for Black. For example, 24... Bd8 25.Re7+ Kf8 26.Qf3+ Kxe7 27.Qf7#.

B) 22... Qxe4 23.Nxe7+ Kf8 (23... Kh8 leaves the other bishop defenseless) 24.Bxc5 dxc5 25.Bg2 Qe3+ 26.Kh1 Rb8 (26... Ra7 27.Qd8#) 27.g6 wins decisive material (27... hxg6 28.Nxg6+).

C) 22... Bd8 23.Rxf7

C.1) 23... Kxf7 24.Qh5+

C.1.a) 24... Kf8 25.Rf1+ Qxf1 (25... Kg8 26.Qe8#; 25... Bf6 26.Nxf6 looks crushing) 26.Kxf1 exd5 27.Bxc5 dxc5 28.exd5 + - [Q+P vs R+N].

C.1.b) 24... g6 25.Qxh7+ followed by 26.Bxe6 looks winning.

C.1.c) 24... Kg8 25.Qe8#.

C.2) 23... exd5 24.Qf3 Bc7 (24... Be7 25.Rxe7) 25.Rf8+ Rxf8 26.Be6+ and mate in two.

Jun-05-15  Tiggler: <goodevans: Right moves, wrong order.

Just like <latebishop>, I tried to start with <22.Nd5> to cut off the defence of e6 before sacking the exchange on f7. Maybe this move order works too?>

It doesn't, but 23.Nd5 before 24.Qh5 transposes.

I did not consider 24. ..Bf8, but it is not best.

Jun-05-15  scormus: Nice clear start to the sequence, with B playing all the natural moves (albeit not forced). But W seems to make a meal of it from 26 Qf7 onward. 26 Nf6 looks simpler and more direct, unless I miss something
Jun-05-15  BOSTER: <abuzic: After 22.Rxf7 Kxf7 both 23.Nd5 and Qh5+ are winning >. This is wrong.
After 23.Nd5 black can play Qxe4 , if 24.Qh5+
Qg6 25.Bxg6+ Ke8 , or 23...Rxd5.
Because move 23.Nd5 is not forced I'd say
this is wrong in this pos.
Jun-05-15  scormus: I stand corrected. Engine gives the very nice 26 Bf5, an absolute killer. 26 Nf6 also wins but is more messy after ... Rxg5+ 27 Bxg5 Qd4 28 Kh1
Jun-05-15  houtenton: <scormus> 26.Nf6 looks very good and is winning indeed, like it is mentioned earlier today by <MJCB>.
Jun-05-15  Tiggler: <BOSTER>:<Because move 23.Nd5 is not forced I'd say this is wrong in this pos.>

One could contradict you, and say it is actually best. But nevermind.

  Penguincw: Hehe, a Friday night puzzle.

Anyway, my streak of 2 in a row comes to an end here, but just like basically everyone else, I got 22.Rxf7 Kxf7 23.Qh5+ Kg8. I was then going to play 24.Rf1, but moves like 24...Rf8 shut that threat down quickly.

Jun-05-15  abuzic: <BOSTER: <abuzic: After 22.Rxf7 Kxf7 both 23.Nd5 and Qh5+ are winning >. This is wrong. After 23.Nd5 black can play Qxe4 , if 24.Qh5+
Qg6 25.Bxg6+ Ke8 , or 23...Rxd5.
Because move 23.Nd5 is not forced I'd say
this is wrong in this pos.>

<Tiggler> has commented on this: <One could contradict you, and say it is actually best. But nevermind>

First, after 23.Nd5 Qxe4 24.Qh5+ <Qg6?> 25.Qf3+ threatening the a8 R (better than <25.Bxe6+; I believe wrongly written in your comment as Bxg6+>

25...Ke8

<25...Bf6? 26.Bxe6+ Kf8 <(26...Kxe6? 27.Nf4+; 26...Ke8? 27.Bf5 Qf7 28.Nxf6+ gxf6 29.Qxa8+)> 27.Bxc5 bxc5 28.Nxf6 gxf6 29.Qxa8+>

26.Nxe7 Kxe7 27.Qxa8

Second, after 23.Nd5 <Rxd5?> 24.Qh5+ Kf8 25.Rf1+ Rf5 26.exf5 Kg8

<26...exf5? 27.Qxh7; 26...Qe4? 27.fxe6+ Kg8 28.Qf7+ Kh8 29.Qxe7>

27.f6 Bf8 28.Rf4 g6

<28...Qc8? 29.Rh4; 28...Qd5? 29.f7+ Kh8 30.Rh4; 28...Qa2? 29.Qe8!>

29.Rxc4 gxh5 30.Bxe6+ Kh8 31.Rc7 black's N and B have no safe place to move, his K is strangled; a hopeless position

Jun-06-15  CHESSTTCAMPS: Material is even in this dynamic attacking position. White's chances lie in the exploitation of black's lightly defended king-side, while black's chances lie in counter-play against the vulnerable g5 pawn. White would likely be tempted by grabbing the exchange with 22.Bxc5?, but this bait is best left untouched in view of 22... Qxc5+ 23.Kh1 Qxg5 and the black queen becomes master of the king-side. I found my primary candidate within a minute or two, but finding the right follow-up was harder:

22.Rxf7!! eliminates the best king-side defender and prepares the entry of the white queen.

A) 22... Kxf7 23.Qh5+ Kg8 24.Nd5!! (24.Bf1 Qg4 goes nowhere for white. Playing for mate works better) exd5? 25.Be6+ Kh8 (Kf8 26.Qf7#) 26.g6 h6 (otherwise 27.Qxh7#) 27.Bxh6! gxh6 28.Qxh6#

A.1) 23... g6 (Kf8 24.Rf1+) 24.Qxh7+ Ke8 25.Qxg6+ Kd7 (Kd8 26.Qg8+ picks up Ra8) 26.Nd5! and the threat of Qxe6+ can't be met.

A.2) 24... Qxe4 25.Nxe7+ Kf8|h8 26.Bxc5 puts white a piece ahead with initiative.

B) 22... Bxg5 23.Rf3 and white should hold the extra piece

Never got around to posting this yesterday. Time for review...

Jun-06-15  CHESSTTCAMPS: Failed to consider the 24... Bf8 defense, but otherwise correct.

  patzer2: Here's my look at the Friday June 5, 2015 puzzle (22. ?) and a few key moves in the game with the Opening Explorer and Deep Fritz 14:

<13...Rfc8> Here I prefer the more popular 13... Bc8 as in C Lutz vs Ftacnik, 2006.

<17...Qc4> Here I prefer the Deep Fritz 14 suggestion 17... Nc4 =.

<19...Bf7?> This is a mistake which sets Black on the path to defeat. Better is 19...Nf8 = to .

<20...Nc5?> This is the clear losing move for Black.

Necessary is 20... Bxg5! 21. Bxg5 Nxb3 22. Rxf7! (Not 22. cxb3? Qc5+ 23. Kh1 Qxg5 =) 22... Kxf7 23. Qh5+ Kg8 24. cxb3 when White has a strong advantage but no clear forced win.

<21. Nxc5!> This wins but even stronger is 21. Rxf7!! Kxf7 22. Nxc5 bxc5 23. Qh5+ (+6.90 @ 20 depth, Deep Fritz 14).

<21... Rxc5?> This makes the win too easy for White. Better is 21... Bxg5 !?, when White must find 22. Rxf7! (Not 22. Bxg5? Qxc5+ 23. Kh1 Qxg5 =) 22... Bxe3+ 23. Kh1 Bxc5 24. Re7! Kh8 25. Bxe6 d5 26. Bxd5 Qb4 27. Rd7! Qxb2 28. Bxa8 Qxc3 29. Rd8+ Bf8 30. Rxc8 Qxc8 31. Bd5 (+2.90 @ 21 depth, Deep Fritz 14).

<22. Rxf7!!> This solves our Friday, June 5th, 2015 puzzle.

<22...Kxf7 23. Qh5+! Kg8>

If 23... g6, then White wins with 24. Qxh7+ when play might continue 24...Ke8 25. Qxg6+ Kd7 26. Nd5 Kc6 27. Qxe6 Kb7 (27... Re8 28. Qd7#; 27... Ra7 28. Qc8+ Rc7 29. Qxc7#) 28. Qxe7+ Rc7 29. Nxc7 Qxc7 30. Qxc7+ Kxc7 31. Rf1 Rg8 32. Be6 Rg7 33. Rf7+ Rxf7 34. Bxf7 (+32.37 @ 20 depth, Deep Fritz 14).

If 23... Kf8, White wins with 24. Rf1+ when play might continue 24...Bf6 (24... Kg8 25. Qf7+ Kh8 26. Qxe7 Rc7 27. Rf8+ Rxf8 28. Qxf8#) 25. Qxh7 Rxg5+ 26. Bxg5 Qc5+ 27. Kh1 Qxg5 28. Bxe6 Ke7 29. Qh3 d5 30. Nxd5+ Kd6 31. Bc8 Rxc8 32. Qxc8 (+23.22 @ 20 depth, Deep Fritz 14).

<24. Nd5!> The sham sacrifice of the Knight is essential to assure the win.

<24...Bf8>

If 24... exd5, then White mates after 25. Be6+! Kh8 26. Bf5 h6 (26... g6 27. Bxg6 h6 28. Qxh6+ Kg8 29. Qh7+ Kf8 30. Qf7#) 27. Qg6 Kg8 28. Qh7+ Kf8 29. Be6 Ke8 (29... Bf6 30. Qg8+ Ke7 31. Qf7+ Kd8 32. Qd7#) 30. Qg8+ Bf8 31. Qf7+ Kd8 32. Qd7#.

<25. Bxe6+> This wins but even stronger is 25. Rf1! when play might continue 25...Ra7 26. Bxe6+ Rf7 27. Qxf7+ Kh8 28. Qg8#.

<25... Kh8 26. Qf7 Be7 27. Qxe7> This wins but even stronger is 27. Rf1! .

<27...Nc6 28. Qxd6 Rd8 29. Qf4 Nd4 30. Bxd4 Qxd4+ 31. Kh1 Rxc2 32. Rf1 g6 33. Qf8+ 1-0>

Black resigns in lieu of 33...Rxf8 34.Rxf8+ Kg7 35.Rg8#.
