|Feb-27-07|| ||percyblakeney: Here little known Zinkl wins one of two briliancy prizes in Berlin 1897, the other went to H Suechting vs Metger, 1897|
|Jan-26-12|| ||dzechiel: White to move (23?). White is up a pawn. "Medium."|
White would love to play 23 Qh6 followed by 24 Qg7#, but black would spoil that plan by playing 23...Qxh3+.
So, how does white keep his options open, but stop black's plans in their tracks? With...
The rook acts as a blockade on the c8-h3 diagonal, and it cannot be taken using the pawn, eg: 23...gxf5 24 Qg5+ Kh8 25 Qg7#.
So, what does black do? Probably resign. White will play 24 Qh6 next move and the only way to slow white down is capture the pawn on f6, giving up a whole queen.
Time to check and see how this played out.
Black had a little more play, but the end was the same.
|Jan-26-12|| ||acme: 23. Rf5! will force mate.|
|Jan-26-12|| ||rhickma4: A simple blocking move allows White time to play Qh6|
23.Rf5 Kh8 (what else?) 24.Qh6 Rg8 25.Ng5 1-0
|Jan-26-12|| ||Phony Benoni: 23.Qh6 beckons, but 23...Qxh3+ would spoil everything perpetually. Can we cut off the queen? Try volunteering the rook with 23.Rf5. Looks good.|
Black's only desperate attempt to guard g7 is 23...Kh8 and 24...Rg8, but 25.Ng5 kills. Failing that, he probably has to give up his queen with something like 23...gxf5 24.Qh6 Qxf6.
|Jan-26-12|| ||kevinatcausa: Bah...yet again didn't quite think things all the way through. |
Saw the Qh6-g7 threat, saw black's counter via Qxh3, saw that Rf5 blockaded quite nicely, and thought that was it. Didn't see that I needed to think about Rg8 at all, though sheer blind luck (and the fact that this was a solvable puzzle) made things work out.
|Jan-26-12|| ||waustad: I actually got it fairly quickly. For me that's good on a Thursday.|
|Jan-26-12|| ||lost in space: White has to cover Black's threat Qxh3 before he can try to mate with Qh6.|
First I thought about moves like Kg1, but this allows Black to organize a defense.
So something more forcing is requested.
23. Rf5! and White treat is covered without time for Black to organize the defense. eg.
a. gxf5 24. Qh6 Qxf6 (else mate) Qxf6 1:0
b. Qxg5 24. exf5 Kh8 25. Qh6 Rg8 26. Ng5 and mate
c. Kh8 24. Qh6 Rg8 25. Ng5 and mate
|Jan-26-12|| ||M.Hassan: "Medium" White to play 23.?
White has a Knight and a pawn for a Bishop
After not seeing any results from 23.Ng5 or 23.Qh6 (which is in fact dangerous and possibly leads into a draw), the right move snapped on me:
This move closes the diagonal occupied by Black Queen and the Queen can not capture it because it is supported by e4 pawn or at the most can capture it but loose the Queen.
|Jan-26-12|| ||TheBish: A Zinkl vs Metger, 1897|
White to play (23.?) "Medium", White is up a pawn.
Black is threatening 23...Qxh3+, so White obviously has no time for 23. Qh6 Qxh3+ 24. Kg1 Qxg3+ with a draw. Also, 23. Ng1 gives Black time for 23...Kh8 24. Qh6 Rg8 and White's knight is two moves away from playing Ng5, so retreating leaves something to be desired. White needs a bolder plan.
23. Rf5! Kh8
There is nothing better; if 23...gxf5 24. Qg5+ Kh8 25. Qg7#.
24. Qh6 Rg8 25. Ng5 and mate next move.
Of course, Black could play 23...Qxf6 24. Rxf6, but this only delays mate; giving away the queen would be completely hopeless.
|Jan-26-12|| ||FSR: 23.Rf5! Kh8 (23...gxf5 24.Qg5+) 24.Qh6 Rg8 25.Ng5 1-0|
|Jan-26-12|| ||whiteshark: Easy-peasy|
|Jan-26-12|| ||sevenseaman: White has all his Ps, Black is one off.
Main idea has to be to <cut off the Black Q's> killing sight on h3 or cater to cover it.
i) N move, to g5. Defensive. It forces a decision on the Black Q; a retrograde return to base. But does not move White's attack portfolio.
ii) Q to h6? Can only be a wish in view of a very sore h3.
iii) Can the R to f5 be a candidate? Yes; not even the 'g' P can take it. Very promising, cuts off the Black Q and opens an excellent vista to the White Q.
Black cannot afford to capture it with the 'g' P as that opens even g5 for the Q. Black's options? Only one, K to h8. I can see game over.
<23. Rf5 Kh8 24. Qh6 Rg8 (a death pang) 25. Ng5>; 1-0 without an actual check or bloodshed.

Checking up is really superfluous, 'cept for a spoiler.
|Jan-26-12|| ||stacase: That was fun!
I probably would have gotten this one over the board. Sometimes the solution to these puzzles jumps out at you and other times not. I had to spend a little time to see if it actually worked.
|Jan-26-12|| ||scormus: B is helpless against the # threat on g7 but threatens ... Qxh3+ himself. Oh yes, 23 Rf5 :)|
|Jan-26-12|| ||rodchuck: What about 23 Ng1? Is there defence against 24 Qh6? It is perhaps not so elegant, but it looks like the same result|
|Jan-26-12|| ||Shams: <rodchuck> Yes, same defense as was tried in the game, ...Kh8-Rg8. Only here it works since White's Knight is back home in bed.|
|Jan-26-12|| ||Phony Benoni: <percyblakeney: Here little known Zinkl...>|
Zinkl, Zinkl, Little Star?
|Jan-26-12|| ||Once: Some folk collect stamps. Some collect notches on the bedposts and annoying little itches. Me, I collect Hollywood cliches. Those snippets of dialogue and plotting that directors just cannot resist using again and again.|
And today's little gem is ... shooting your own guys. There are two variations of this theme. The first is the really evil baddie who shoots his own soldier through callousness. The second is the heroic commander who is forced to kill a colleague because their really is no choice. The difference is that the baddie doesn't flinch. The hero agonises about it over and over again.
Examples? For the baddies we have Darth Vader force-strangling a death star officer. Die Hard 2 (replace the tower block with an airport). The orcs in Lord of the Rings. Just about any german officer in WW2 films. A normal day in the office for Ming the Merciless.
For the good guys ... almost any film set on a submarine. At some point someone is going to have to seal off a compartment which is flooding. But his own men are inside! Oh, the horror, dilemna, the struggle, the humanity of it all...
Chess doesn't work that way. We can send our own men forwards to be killed by the enemy, but we absolutely cannot kill them ourselves. And that can give rise to some frustrating situations. Take today's POTD a couple of moves earlier than the puzzle position:

White would love to play 22. Qh6, but his own knight is in the way. In an ideal world we would love to flood the compartment by turning one of those wheely things on the ceiling. I've always wondered, by the way, why submarine commanders don't go round and twiddle all of those wheels before the battle starts. It always seems to turn the water off, so why not leave them turned off permanently?
Then we have our puzzle. With 23. Rf5 we offer up the rook. If black retakes with 23...gxf5 his own pawn blocks his queen's attack on h3. He'd love to whip out a pistol and shoot his pawn, but that's against the rules, dear boy. Not cricket.
Finally we get to the finality that is ultimately called the final position:
click for larger view
The black queen or bishop desparately need to be able to defend h7. But - guess what? - their own pieces (and some of white's) are standing in the way. What you wouldn't give for a luger...
|Jan-26-12|| ||offramp: A standard Stoke-Adams Attack.|
|Jan-26-12|| ||newzild: THURSDAY 3:55-4:06
White is a pawn up with a strong position, but he does not have time for 23. Qh6 because of 23...Qxh3+. My first candidates involve moving the knight:
23. Nf4 Qxf6 and there is no good follow-up for White, as his knight is pinned against the Rf1.
23. Ng5 Qe5 and the Knight has blocked the Queen's route to h6, which seems undesirable.
23. Ng1, threatening 24. Qh6 looks strong, but Black can defend with 23...Kh8 24. Qh6 Rg8
So, lets look for some other way to stop Black from captureing the Knight while allowing White's queen access to h6.
23. Rf5 Kh8 (23...gxf5 24. Qh5+ Kh8 25. Qg7#) 24. Qh6 Rg8 25. Ng5
and mate is inevitable.
Time to check, but I'm pretty sure about this...
|Jan-26-12|| ||newzild: Nailed, it, but a couple of typos in my post.
1) "Captureing" is of course "capturing" (slightly embarrassing for someone with a BA in English Literature, an MA in Applied Linguistics and an almost-finished novel in my top drawer).
2) In my final sub-varation I should have said 23..gxf5 24. Qg5+, rather than 24. Qh5+
|Jan-26-12|| ||agb2002: White has a knight and a pawn for a bishop.
Black threatens 23... Qxh3+ which leads to perpetual if White plays 23.Qh6.
These details invite to play 23.Rf5 and Black will have to trade the queen for the pawn on f6 to avoid mate.
|Jan-26-12|| ||cocker: I echo the comments of <waustad>.|
|Jan-26-12|| ||morfishine: <23.Rf5> and Black is kaput. There are a few chess themes at work here like interference by the rook (or is this more accurately termed an 'obstruction' sac?); and the Queen arriving at <h6> with 'tempo'; and when the knight arrives at <g5> we have a 'concentration of force'. |
Other than that, the position is like a slab of beef jerky: cut and dried
