May-06-11  Patriot: I believe I spent 9 minutes on this, thinking along the same line as <CHESSTTCAMPS> and also at declining the bishop sac. The game variation is not what I expected.
May-06-11  David2009: R Nizam vs G Nemes, 2007 White 27?

23 Bxh7+ is promising, seeing at minimum 23...Kxh7 24 Qh5+ Kg8 27 Qxf7+ Kh7 28 Qh5+ Kg8 29 Qe8+ Kh2 30 Rxc8 Rxc8 31 Qxc8 and White is two Pawns up. There may be better moves on the way, but White does not have to decide this when making the initial sacrifice. Black can decline the sactifice, e.g. 23...Kh8, but White can continue 24 Bb1 winning a Pawn, threatening mate, and improving his position. Time to check:
I got enough of it - I did not see the elegannt refutation of 23...Kf8 as played in the game. I support the pragmatic approach of <CHESSTTCAMPS> in this sort of position. Here's the puzzle position

and here's a link to a well-known public Internet chess engine: you play on as White from the puzzle position to explore some variations and/or win the endgame.

May-06-11  Ropitybopity: I think I have an answer to "what after (23...Kxh7 24.Qh5+ Kg8 25.Qxf7+ Kh8!)?"

Yes, 26.Qe8+ gets the same result as if 25...Kh7 were played (rook and bishop for queen) but I'm sure 26.Ng6+!! forces mate. After 26.Ng6+ Kh7 27.Re4!! black has many replies:

27...Ra7 or Rd7 then 28.Nf8+ Kh8 29.Rh4+ Bxh4 30.Bxg7#

27...Be6 or Bf5 then 28.Rh4+ Bxh4 30.Qxg7#

27...Kh6 then 28.Nf8 Bf5 29. Rh4+ Bxh4 (Kg5 30.Qh5#) 30.Qxg7+ Kh5 31.g4+ Bxg4 32.hxg4# or 28.Nf8 Rg5 29.Rh4+ Rh5 30.Rxh5#
or 28.Nf8 Bxb2 29.Rh4+ Kg5 30.Qf4#

27...Rh5 then 28.Nf8+ Kh8 29.Qxh5+ Kg8 30.Qh7+ Kf7 (Kxf8 31.Qh8+ Kf7 32.Qe8#) 31.Bxf6 Qxf6 32.Rc7+ and white has achieved alot more than rook and bishop for queen :)

I hope all this is accurate or I will feel very foolish.

May-06-11  aniceto: <Ropitybopity> <I think I have an answer to "what after (23...Kxh7 24.Qh5+ Kg8 25.Qxf7+ Kh8!)?"> I went too for 26. Ng6+, but after Kh7 27. Nf8+ is better. It forces 27...Kh8 and then 28.Re8

(Would that qualify as a GOOT!, <Once>?)

May-06-11  Ropitybopity: Very nice <aniceto>! But I don't think it forces mate like 27.Re4 does, because of the move 28...Rd8

If I am wrong I apologize in advance.

May-06-11  twin phoenix: A nice game! i saw the classic bishop sac 23. Bxh7+! and calculated what would happen if it was accepted... i didn't calculate what to do after the game continuation and so feel like NO i didn't solve. so close yet so far away.
May-06-11  gofer: <Once> you were wondering how to win in the following position.

click for larger view

How about...

<26 Ng6+ Kh7>
<27 Nf8+ Kh8>
<28 Re8! ...>

click for larger view

White threatens 29 Ng6+ Kh7 30 Rh8# and so white has to move Bc8, which means losing Ra8. Crafty plays Bxh3 and loses quickly?

<28 ... Bxh3>

White can either play...

<29 Rxa1 Qxf2+>
<30 Kxf2 Rf5+>
<31 Kg1 Bd4+>
<32 Bxd4 Rxf7>
<33 Ne6+ Kh7>
<34 Ng5+ Kg6>
<35 Nxf7 Kxf7>
<36 gxh3 ...>


<29 Nd7+ Rxe8>
<30 Qxe8+ Kh7>
<31 Nxb3 Bxb2>
<32 Nxd5 Bxc1>
<33 Nxb4 Bxg2>
<34 Kxg2 ...>

May-06-11  Ghuzultyy: Puzzle Position;

click for larger view

There is a huge weakness in Black's defence. f7 pawn. After this move a couple of forced moves will lead to a big attack on f7.

Black has two choices here. 23...Kh8 is obviously worse than 23...Kxh7 so;


click for larger view

Seems OK at first sight but let's imagine Bishop on c8 and Rook on d5 were not on the board. Than Nd7 would be mate. Time to remove the defenders.

This should be played first with tempo.

24...Ke7 doesn't save black neither.


click for larger view

Next move white can play Nd7#,Qxf7#,Ng6+ and black can't defend all.

Only move left.

<24.Qh5+! Kg8> <25.Qxf7+> Using the f7 weakness.

click for larger view

(25...Kh8? 26.Ng6+ Kh7 27.Nf8+ Kh8 28.Re8! White wins.)

<26.Qg6+ Kg8>

click for larger view

Playing the knight to anywhere else would let black defend the last rank by moving the bishop on c8. Now black has to defend both e8 and the queen.

(27...Qc6?? loses after 28.Bxf6)

click for larger view

<28.Re8+ Rxe8 29.Qxe8+ Kh7 30.Nxb6> and white wins.

Thats it.
Im sorry if there are any mistakes on diagrams or variations :/

  patzer2: Like most other posters, I found the first move 23. Bxh7+! as the solution to today's Friday puzzle, but had difficulty with finding the win to exploit the helpless King position in the followup.

The question <Once: After 23. Bxh7+ Kxh7 24. Qh5+ Kg8 25. Qxf7+ Kh8 - exactly how do we continue the attack?> puzzled many of us.

To be honest, once I saw White had at least a draw by perpetual in this line, I took a peek at the solution, and plugged it into the computer to check out the complexities in the position.

Here's some analysis, based on a move-by-move look with Fritz:

<23. Bxh7+!>

The tempting 23. Nd3!? fizzles out to only a small advantage after 23...Bb7 (not 23... Bxb2?? 24. Re8# or 23... Nxd3?? 24. Re8#) 24. Qe2

<23... Kf8>

If 23... Kh8, then 24. Qh5 Bxe5 (24... Be6 25. Bf5+! Kg8 26. Qh7+ Kf8 27. Ng6+ fxg6 28. Bxe6 Rdd8 29. Qg8+ Ke7 30. Bf5+ Be5 31. Qxg7+ Ke8 32. Rxe5+ Qe6 33. Rxe6#) 25. Bg6+ Kg8 26. Bxf7+ Kf8 27. Bxd5 wins decisive material.

If 23... Kxh7 24. Qh5+ Kg8 25. Qxf7+ Kh7 (25... Kh8 26. Ng6+ Kh7 27. Nf8+ Kh8 28. Re8 ) 26. Qh5+ Kg8 27. Qe8+ Kh7 28. Qg6+ Kg8 29. Nc4 gains enough material for an easy win.

<24. Qxd5!>

This is a clear and strong winning move, but even stronger is 24. Rxc8+! Rxc8 25. Qxd5 Ke7 (25... Bxe5 26. Qxe5) (25... Nxd5 26. Nd7#) 26. Ng6#.

<24... Nxd5 25. Rxc8+ Rxc8> This allows mate-in-one as in the game continuation.

However, Black can prolong the game with White having a clearly decisive material advantage after 25... Ke7 26. Nc4+ Qe6 27. Rxe6+ fxe6 28. Rxa8 bxc4 29. Ba3+ Kd7 30. bxc4 .

If reaching the time control were an issue, the quicker ending with 24. Rxc8+! (in lieu of 24. Qxd5!) could have been an issue. Otherwise, winning more slowly with 24. Qxd5! was fine.

< 26. Nd7# 1-0>

P.S.: Instead of 19. dxe5?!, it appears 19...Nxe5 would have given Black a very defensible position. Other possible improvements that might have given Black better practical defensive chances are 20...Qb7 or 20...Qb8 and 22. Nxc2 . After some analysis, it's clear 22...Rxd5? loses immediately to a deeply calculated 23. Bxh7+!

May-06-11  psmith: <VincentL>:

In your line (b) 23.....Rxd1 24. Re8 mate is, unfortunately not a legal move. (The R on e1 is pinned.)

  Jimfromprovidence: To <Once> and others regarding the comments after 23. Bxh7+ Kxh7 24. Qh5+ Kg8 25. Qxf7+ Kh8 below.

click for larger view

I had the answer in my hip pocket but I did not post it since it was early in the kibitzing so I thought that others would pick up that thread.

Anyway, one continuation I liked from that position was 26 Qe8+ Kh7 27 Qg6+ Kh8? 28 Nf7+ with mate next move.

May-06-11  Bignevermo: i got it.... but only cause i knew it was a puzzle.... in real games...i aint that brite!! :)...
May-06-11  Patriot: <Bignevermo> LOL...Most of us probably wouldn't have gotten it in a game, depending on the time remaining.
May-06-11  DarthStapler: I didn't get it

  takchess: I didn't obey my cardinal rule: Always calculate the bishop check on f7 or h7.
May-06-11  pitimutis: Great sac. Harder than it seemed at first.
May-06-11  Marmot PFL: I found a win with Bxh7+ Kxh7 Qh5+ Kg8 Qxf7+ Kh7 Qh5+ Kg8 Nc4 threatening the queen as well as Re8+.

Unfortunately I never considered declining with Kf8, although it is a critical line. In fact I won a blitz game earlier today playing Kf8 after such a check (was a desperation sac there as black was up a lot of material).

May-06-11  cyclon: 23.Bxh7+ Kf8 ( -Kxh7 24.Qh5+ Kg8 25.Qxf7+ Kh8 [or -Kh7 26.Qg6+ K- 27.Nc4] 26.Qe8+ Kh7 27.Qg6+ K- 28.Nc4) 24.Rxc8+ Rxc8 25.Qg4.
May-06-11  SufferingBruin: Haven't logged on in a while.

That puzzle was cool. 'Nuff said.

May-06-11  cyclon: I missed the point, 24.Qxd5.
May-06-11  tacticalmonster: 23 Bxh7+ and Black has three replies: 23 Kxh7, Kh8 and Kf8

a) 23 Kxh7 24 Qh5+ Kg8 25 Qxf7+

a1) 25 Kh8 26 Ng6+ Kh7 27 Nf8+ Kh8 28 Re4!- Black will be mated or heavy loss of materials

a2) 25 Kh7 26 Qg6+ Kg8 27 Nc4! Qd8 28 Re8+ Qxe8 29 Qxe8+ Kh7 30 Bxf6 bxc4 31 Qf7

b) 23 Kh8 24 Qh5 Bxe5 25 Bg6+ Kg8 26 Qh7+ Kf8 27 Rxc8+ Rxc8 28 Bxe5 Qe6 (28...Rxe5 29 Rxe5 Rc1+ 30 Kh7 Qe6 31 Qh8+ Ke7 32 Qxg7 ) 29 Qxg7+ Ke8 30 Bxf7+! Qxf7 31 Bf6+

c) 23 Kf8 24 Rxc8+! Rxc8 25 Qxd5! Bxe5 26 Qxe5 Qf6 27 Qg3! - mate or loss of queen

May-07-11  butilikefur: 23. Bxh7+ Kf8 24. Qf3 is probably best but the following is more fun...

<23. Qh5 g6 24. Qh6> 24. Ng4 doesn't work because of the queen on b6

<24...Rxe5> 24...Be6 25. Nxg6 fxg6 (25...Bxb2 26. Ne7+ Kh8 27. Qxh7+ mate, 25...Rh5 26. Ne7+ mates) 26. Bxf6 Rd7 27. Bxg6

24...Bxe5 25. Rxe5 Rxe5 26. Bxe5 f6 27. Bxg6 hxg6 28. Qxg6+ Kf8 29. Bxf6 is totally lost (e.g. 29...Qe6 30. Rc7 or 29...Qb7 30. Re1)

24...Bg7 25. Nxg6 looks like forced mate (e.g. 25...Qxg6 26. Re8+, 25...f/hxg6 26. Qxg7+ mate, 25...Bxb2 26. Qf8+ mate, 25...Bxh6 26. Re8+)

24...Nxc2 25. Nxg6 wins again

<25. Rxe5 Be6> 25...Bd7 26. Be4 Rd8/Rb8 27. a3 looks like it wins the knight

<26. Rxb5> 26. Rh5 Bxb2 27. Qxh7+ Kf8 28. Bxg6 Bxc1 (28...fxg6 29. Qxg6 Bxc1 30. Qf8+ Ke8 31. Rh8+ Kd7 32. Rh7+ Kc8 [32...Kd6 33. Qe7+ Kd5 34. Rh5+ Ke4/Kd4 35. Qxb4+ looks winning] 33. Qf8+ Qd8 34. Qc5+ Kb8 35. Qe5+ wins) 29. Rf5 Qc7 30. Qh8+ Ke7 31. Qf6+ Kd7 and White has no tricks left (e.g. 32. Bxf7 Bxf5 33. Qxf5+ Kd6 34. Qe6+ Kc5 and no checks... maybe 35. a3)

26...Bxb2 27. Rxb6 Bxc1 28. Qxc1 Rc8 29. Qd2 Nxc2 30. Rxe6 fxe6 31. Qd7 looks like it finishes things

May-07-11  M.Hassan: Worked hard on this puzzle but could not solve it.
May-07-11  butilikefur: in the line with 28...Rc8 the stupid knight is hanging on b4.

  kevin86: A supurb finish! White was going after checkmate,not the queen fork.
