  al wazir: Well, I got the first move. But if I had seen 19. Nf6+ gxf6 20. Qxe6+ fxe6 Bh5# I'd have broken an arm patting myself on the back.

<18.?>

The first move is easy enough to see after a minute or so. Rook wants to go to d8, knight blocks his way, so 18.Qxe5+ and Black can't take with the knight. But what after 18...Qe6?

Obvious is trading queens and playing 20.Bh5+, then figuring out what to do after 20...g6. The light goes on when you realize the g7 pawn might not stay there forever!

Probably a lot of complaints that it's too easy for a Saturday by people who see the second move. But it's hardly trivial.

Aug-06-11  RMKvdS: 18. Qxe5+

A) 18... Nxe5 19. Rd8#

B) 18... Be7 19. Qxe7#

C) 18... Qe6 19. Nf6+ gxf6 20. Qxe6+

C1) 20... fxe6 21. Bh5#
C2) 20... Be7 21. Qxe7#

Pretty easy for a saturday in my opinion, since it is absolutely forced! Nice mate anyway.

  rhickma4: I thought the first move here was obvious, but the continuation took a little while

18 Qxe5+ Qe6 (not 18...Nxe5 Rd8#) 19.Nf6+ gxf6 20.Qxe6+ fxe6 21.Bh5#

Aug-06-11  IRONCASTLEVINAY: I found the first move in few time but then could not find continuation, Then i see the answe, amazing , Everything was there.

  Eggman: I did not find this to be difficult, considering its forcing nature. I think it took me about 30 seconds to find 1.Qxe5+ Qe6 2.Nf6+ gxf6 3.Qxe6+ fxe6 4.Bh5# Probably the easiest Saturday puzzle I've seen. Nice, though.
Aug-06-11  patzer2: Add me to those who found 18. Qxe5+! Qe6, but missed 19. Nf6+! turning it into a mate-in-four.

Instead of looking for something better, like the clever mating continuation in the game, I settled for 19. Qxe6 fxe6 20. Ng5 to .

  whiteshark: This game is from the the German Bundeliga and has been played by Frank Zimmermann and <Wolfgang Huebner>, who is the elder brother (* 17. Juni 1943) of Robert Hübner.

Wolfgang is so far not a player in the ceegee database.

Aug-06-11  ounos: When I saw the first move, I thought "is this Monday?". When I failed to see the second, I realized this was a good Saturday puzzle alright

  sevenseaman: On the face of it, the Saturday POTD looks tough; but not after the Q check at e5.

a) <18. Qxe5+ Nxe5 19. Rd8#> b) <18...Qe6 19. Nf6+ gxf6 (If Nxf6 Rd8# as in a).)20. Qxe6+ fxe6 21. Bh5#

Very enjoyable puzzle today! Yesterday the first move was of the essence of the POTD but today it is the continuation. 19. Nf6+ may be the most likely hurdle. The trick is to give oneself plenty of thinking/ analysis time.

I did go into an alternative line momentarily;

19. Qxe6+ fxe6 20. Nf6+ and saw the Black K go to f7 rather than respond gxf6. (This killed my line.)I had no answers, at least not a quick fix as Black has saved his g7 P for my B+.

(Removing the f6 N now gives the K the option to slip into g8 with hell to pay.)

Tricky, unless you do it just right. For me the discovery of the simplistic line a) was the inspiration.

Aug-06-11  consul: Wow, i didn't see 19. Nf6+, and i relied on Bg4, with an unclear position. And yet i was thinking about Qxe6+ followed by Bh5+, but i rejected it because of g6... I wasn't able to put things together.
Aug-06-11  Sularus: got it! i spent a few seconds trying to make a knight mate work, but to no avail. then somehow everything clicked in the span of less than four minutes.

damn, i feel good!

  sevenseaman: <eggman> Doing it in a mere 30 seconds is miraculous. Makes me feel a very heavy-footed plodder(5 minutes or maybe more). Speed will come, though I'll never be super-sonic.

<al wazir> Ditto here, but I got away with a sprain.

<PB> I agree; it was tricky.

Aug-06-11  abstract: Nice game for Zimmerman but a poor profile for this player.
Aug-06-11  Artsemthon: 18.Qxe5+ Qe6 (18...Nxe5 19.Rd8#, 18...Be7 19.Qxe7#) 19.Nf6+ gxf6 (19...Nxf6 20.Rd8#) 20.Qxe6+ fxe6 (20...Be7 21.Qxe7#) 21.Bh5#.

  FSR: IMO, not as difficult as the star rating suggests. The first move is obviously 18.Qxe5+!, when the obvious 18...Nxe5 fails to 19.Rxd8#. Instead, 18...Qe6 is forced. Here I looked at 19.Rxd7, but White has nothing after 19...Bxd7. Then I thought of 19.Qxe6+ fxe6 20.Bh5+, but White has nothing after 20...g6, since the king has a flight square on f7.

Now it dawned on me: 18.Qxe5+! Qe6 19.Nf6+!! gxf6 (19...Nxf6 20.Rd8#) 20.Qxe6+! (now that White has diverted the g-pawn from its appointed mission of interposing itself to the bishop check) fxe6 21.Bh5#! Was this a Polugaevsky Variation? This looks like the kind of nightmare that happens in a Polugaevsky gone wrong.

Happy birthday to me!

Aug-06-11  Uvulu: 18. Qxe5+
A) 18. ... Nxe5 19. Rd8#
B) 18. ... Be7 19. Qxe7#
C) 18. ... Qe6 19. Nf6+
a) 19. ... Nxf6 20. Rd8#
b) 19. ... gxf6 20. Qxe6+ fxe6 (20. ... Ae7 21. Qxe7#) 21. Bh5#

  lost in space: Got it.

I made a few circles to see the right idea. My first thout was 18. Rxd7 to make 19. Qxe5 work. But after 18. Rxd7 Bxd7 19. Qxe5 Qe6 there is nothing at all.

So a second thought: Rd8# is the threat:

18. Qxe5+ Qe6
(other moves are not o.k.: 18...Be7 19. Qxe7#; 18... Nxe5 19. Rd8#)

19. Nf6+!!
This took me ages to see. It is all about avoiding the move g7-6 and to make Bh5 lethal. Has to be a check otherwise Black can play Qxe5)

19...gxf6 20. Qxe6+ fxe6 21. Bh5#

Nice and forced. Like it a lot. Surprising that Hübner lost in just 20 moves.

Aug-06-11  Elrathia Kingi: King is stalemated, so any check wins. The N is en prise, so the queen needs to be dealt with. Once I saw Rd8#, I started looking for ways to deflect the N on d7. Found Qxe5 Qe6 QxQ, fxQ, Bh5+. That is when I realized an extra move was needed -- Nf6+! Took me about three minutes.
Aug-06-11  gofer: How can this be "Very Difficult"? Black is in a mating net with no less than 4 other pieces able to deliver some sort of check! Lets go for the most forcing move...

<18 Qxe5+ ...>

18 ... Nxe5 19 Rd8#
18 ... Be7 19 Qxe7#

<18 ... Qd6>
<19 Nf6+ ...>

19 ... Nxf6 19 Rd8#

<19 ... gxf6+>
<20 Qxe6! ...>

20 ... Be7 21 Qxe7#

I would imaging Black resigns at this point.

<20 ... fxe6>
<21 Bh5#!>

Very neat. Very nice. But not Saturday level. Time to check!

  lost in space: The losing move was 14....Nd7. 14...Rb7 and Black is somehow o.k. in this complicated position.
Aug-06-11  gofer: <FSR>: Many happy returns of the day to you! My your birthday be as wonderful as Eeyore's. (But I don't really mean this one http://en.wikipedia.org/wiki/Eeyore... )
Aug-06-11  goodevans: <gofer ... Very neat. Very nice. But not Saturday level.>

I was thinking exactly the same. Any puzzle I can get in under 30 seconds isn't "very difficult"!

  David2009: Zimmermann vs Huebner, 1977 White 18?

There appeas to be a very attractive mate in the main variation: 18.Qxe5+ Qe6 19.Nf6+! gxf6 20.Qxe6+ fxe6 21.Bh5#. Time to check:
=====
Here's the position just before White played 17.Kb1:

with Crafty End Game Trainer link http://www.chessvideos.tv/endgame-t... After 17.Kb1 the EGT replies with 17...f5 (instead of 17...e5 as in the game) with an interesting struggle in prospect, which I leave to the interested reader to win with or without silicon help.

In the actual puzzle position, the EGT is duly mated in four moves. Link for those interested in exploring White alternatives: http://www.chessvideos.tv/endgame-t... Have fun! In both these interactive links, you are white, drag and drop the move you want to make.
