Aug-10-16  nalinw: Looked at Nf5+ but didn't see the open diagonal after .... exf5 - saw the other wins.

Was also thinking about
21. Nf6 Kxf6
but then the e pawn is there to block the diagonal. That may be why I didn't see the check along the diagonal in the other variation ....

Moral of the story - When considering a move one must flush all concepts from the previous move

Aug-10-16  saturn2: I settled on Nf5+
If gxN then Qg5+
If exN then Qd4+
If the black king walks he looses a rook or the queen by a pin.
Aug-10-16  Mendrys: Masterly use of the gaping hole left by the exchange of the dark squared bishops. In his last 3 moves Seifert either left a piece en prise or put one so on purpose.

Too bad I didn't solve this one though.

Aug-10-16  plumbst: Surprisingly, White has a forced mate after 21.Nf5+!. All Black responses have a fatal concession, e.g. 21...Kg8 22.Nf6+, 21...gxf5 22.Qg5+, and 21...exf5 22.Qd4+.

  agb2002: White has a knight and a pawn for a bishop.

Black threatens Rxh5 and exd5.

The dark squares around the black king are weak and the white pieces already control many of them. This suggests 21.Nf5+:

A) 21... exf5 22.Qc3+ f6 (else 23.Q(R)xh8#) 23.Qxf6+ Kg8 24.Rxh8#.

B) 21... gxf5 22.Qg5+ Kf8 23.Rxh8#.

C) 21... Kg8 22.Rxh8+ Kxh8 23.Qh6+ Kg8 24.Qg7#.

D) 21... Kf8 22.Rxh8#.

Aug-10-16  gofer: Nice simple forced mate in 4...

<21 Nf5+ ...>

21 ... Kf8 22 Rxh8#
21 ... Kg8 22 Rxh8+ Kxg8 23 Qh6+ Kg8 24 Qg7#
21 ... gxf5 22 Qg5+ Kf8 23 Rxh8#

<21 ... exf5>
<22 Qb2+/Qc3+/Qd4+ ...>

22 ... Kf8/Kg8 23 Rxh8#

<22 ... f6>
<23 Qxf6+ Kg8>
<24 Rxh8#>

~~~

Yep.

In hindsight, could black have survived after giving up the a1-h8 diagonal and letting white's rooks run free on the whole of the king-side?!

Or was that choice a "positional no-no"?

Aug-10-16  David2009: H Seifert vs M Szmyd 21? White presumably goes for the throat with 21.Nf5+ exf5 (or gxf5 22.Qg5+) 22.Qd4+ etc. Time to check:
====
Yes
Aug-10-16  Abdel Irada: ∞

<Phony Benoni: And, yes, 22.Qc3+ works fine. I think b2 is the funnier square.>

Nothing says "hypermodern" like a fianchettoed rook, but a queen is a close second.

(Oh, and I think 22. Qd4+ also works.)

Aug-10-16  David2009: <gofer: "I have a question for the group..."> Can Black survive in the alternative line 15.Nxd5 Bxb2 16.Rxb2 Bxd5 17.exd5?

I have no idea. Here's a link to this variation starting from http://www.chessvideos.tv/endgame-t...

Aug-10-16  Chess Dad: One of my few weeks starting 3 for 3.

I'm starting to consider moves that I wouldn't consider OTB when it's a puzzle.

But in this case, with two pieces under attack, OTB I'd likely trade off rooks on h8 and then move Nc3. I'd never consider putting a third piece where it can be immediately taken.

And that's why I'm a patzer.

Aug-10-16  Rama: I kept seeing exf5, Qd4+, e5 blocking. Idiot!
Aug-10-16  lost in space: Nf5! Nuff said
Aug-10-16  YetAnotherAmateur: Nailed this one!

We need to look at forcing moves, and checks are always a good place to start. 21. Rxh7+ and Qh6+ go nowhere, because black's h8 rook can simply take them. 21. Nxe6+ Nxe6 22. Qc3+ wins, but either 21. ... Qxe6 or 21. ... fxe6 recovers. But 21. Nf5+, and black is finished:

A) 21. ... Kg8 22. Rxh8+ Kxh8 23. Qh6+ Kg8 24. Qg7#

B) 21. ... Kf8 22. Rxh8#

C) 21. ... gxf5 22. Qg5+ Kf8 23. Rxh8#

D) 21. ... exf5 22. Qd4+ / Qc3+
--- C1) ... f6 23. Qxf6+ Kg8 24. Rxh8#
--- C2) ... Kg8/Kf8 23. Rxh8#

Aug-10-16  YouRang: Okay, that was good -- but I didn't get it. :-(
Aug-10-16  WorstPlayerEver: After 14... Bc3 15. Qc3 e5 Black wouldn't have all this trouble on the black squares. The irony.
Aug-10-16  Nova: <gofer: "I have a question for the group…">

I would say that the position would be uncomfortable for Black. White has easy threats of Qh6, Ng5…or rook lifts and h-pawn pushes. Probably Black can hold.

I think Black erred earlier in the opening, but I'm not sure where. Does anyone have any insight?

For one thing, I don't understand the point of 11…b6, which seems to weaken the light squares and cuts off the Queen's efforts on the queenside. Perhaps a hedgehog setup may have worked better with getting the Queen to c7, rook to c8, and then queen to a8 and then play …b6.

  kevin86: The white knights being attacked by enemy pawns make a pretty picture. White will mate soon.
Aug-10-16  Joseph Blackcape: My first thought was to take with the Knight on e6 to free the d4 (along with the rest of the diagonal) for the Queen to mate. But wait, after Black takes with the Queen there's no mate and you're a piece down. So 21. ♘f5+ is the next logical choice to free the diagonal with a tempo without giving the Black pieces a chance to get involved. Now no matter if Black takes and with which pawn, the mate follows. More of an easy than a medium puzzle.
Aug-10-16  Cheapo by the Dozen: I tried what felt like several other knight sacrifices first, but before long I found the correct one.

The big clue was that Nxe6+ fails as a clearance sacrifice due to the ... e5 interposition.

  drollere: white is up a pawn and has more space against a porous black K position. black's immediate threats are Rxh5, exd5 and Nxe4, all moves damaging to white's opportunities.

the potential fork at f6 means white might like the black K to end up on h7 or g8. there doesn't seem a way to make that work.

21. Nxe6+ looks interesting, but black has three ways to capture: fxe6 prepares to block the dark diagonal check with e5. so the e6 pawn is revealed as the key piece to displace, provided we can also get the diagonal check.

21. Nxf5+ exf5 (gxf5 Qg5+ and mate)
22. Qd4+ Kf8 (Kg8 Qxh8#)
23. Rh8+ Ke7
24. Qf6#

really? won't play it out? for some reason this one took me quite a while to work out. anyway, i give myself all three moves.

8/9
