Sep-15-08  Woody Wood Pusher: Hi everyone, would somebody mind doing me a favour and analysing yesterdays puzzle with a computer after 23..Nf2.

I have been trying to analyze it myself but I have no software, and some interesting lines come up maybe giving black an advantage. here is the linK

Ziatdinov vs D Gurevich, 1995

Sep-15-08  Geronimo: A very instructive puzzle for beginners and novices. It always strikes me as indulgent when kibitzers announce to all how easy the "very easy" puzzles are. Having experienced this type of position 1000s of times, stronger players see this right away. But for those who newer to chess there is an interesting tactical vocublary to learn from this:

Here there are three pieces that can take the pawn on f7. Newer players often overlook mating oportunities because they are trained to avoid sacrificing the queen. But notice how with 38...Rxf7 black pins his own rook against the bishop on b3. If white took the f7 pawn with either 38.Rxf7?? or Bxf7??, this effect would be lost. [38.Rxf7??, Qxh5 39.Rxf8?? (this would be a second, typical beginner's error, the temptation of double check, and the pleasure of "revealed check" by the bishop is easily refuted by 39...Kxf8 and Black has traded a rook and a pawn for a rook and the queen with a won game.

It is therefore the combination of the forcing move Qxf7+ and the rook pin that makes this so lethal. "Forcing moves", like "pins" "forks" and "points" (or "jumping off points" or "secured" squares") are essential concepts for beginning and novice players to master if they want to develop stronger tactical play.

  johnlspouge: Monday (Very Easy): Negi vs Hebden, 2005 (38.?)

White to play and win.

Material: B for N+P. The Black Kg8 has 1 legal move. An examination of checks, captures, and threats reveals a mate.

Candidates (38.): Bxf7+, Qxf7+

38.Qxf7+ Rxf7 [Kh8 39.Qxf8+ Qg8 40.Qxg8#] 39.Rd8#

The Bb3 pins Rf7 to Kg8.

  johnlspouge: Hi, <Woody Wood Pusher>. My chessforum has detailed instructions for downloading freeware for analyzing chess positions.
Sep-15-08  TheaN: 1/1

<38.?>

White: a2, f3, g3, h2, Bb3, Rd7, Qh5

Black: a6, e5, f7, g7, Nb4, Rf8, Qh7

Material: = (+B vs N)

Candidates: Qxh7, Rxf7, Qxf7

Well, this one went as usual: flashed Qxh7 and saw it was not winning anything, Rxf7 sacs the Queen without compensation: 38.Rxf7?? Qxh5 39.Rf5 Qf7! , so we combine the uselessness of the Black Queen and the weak f7 square:

-ML-
<38.Qxf7!>

/A\
<38....Rxf7 39.Rd8 1-0> and now it shows why the f7 attack of the Bishop was crucial: the Rook was pinned.

/B\
<38....Kh8> hopeless, but mate in two instead one. <39.Qxf8 Qg8 40.Qxg8 1-0>

Sep-15-08  TrueBlue: I just love it how patzers that claim they solved it one nanosecond didn't see that Qxf8 is NOT a checkmate!

Thanks, but I don't have a computer that I can install them on! My computer has no hard-drive and runs off a CD lol

  DarthStapler: I kept thinking Rxf7 Qxh5 Rf5+ Rf7 Rxh5 and win the exchange. I overlooked the most simple solution
Sep-15-08  YoungEd: I'm a guy who thinks he's a class B player but plays more like a class C player--but even I got this one in a split second! Even a blind squirrel finds an acorn once in a while.

  chrisowen: Holy cow Parimarjan crumbles Hebden's army, hemming in the big cheese. Does 16..Bxf3 give white light holes? It is the tactical 37..Qh7 that chokes that in my opinion as the black emperor has no room so speak.

  Once: <Woody Wood Pusher: Hi everyone, would somebody mind doing me a favour and analysing yesterdays puzzle with a computer after 23..Nf2.>

I've got Herr Fritz chewing on it. I'll post the answer against yesterday's game when its done. Looks to be an interesting idea - Fritzie currently reckons that it gives black a small advantage.

  YouRang: Easy, but nice. I guess black didn't notice the back rank mate when he played 37...Qh7??

  lost in space: Hi <once>, I was one of these guys and I recognized it a few nanoseconds too late (as long as a few need to solve a sunday puzzle)

I was waiting for <SuperPatzer 77> or <MAJ> to recognize it.

Cheers

"Checks, captures, and threats."

Look at them <in that order> when you get stuck.

It works for me - most of the time :)

Sep-15-08  Kasputin: There may be more than one method here, but this looks easiest to me:

38. Qxf7+ Rxf7
(or ...Kh8; 39. Qxf8+ Qg8; 40. Qxg8#)
39. Rd8#

The final position reminds me of a typical back-rank mate, except that here black rook and queen are filling in for pawns. I would think that Hebden resigned immediately after 38. Qxf7+

  kevin86: A simple queen sac:after 38...♖xf7 39 ♖d8#-the rook cannot return to f8,because it is pinned. Or 38...♔h8 39 ♕xf8#
Sep-15-08  zb2cr: Hi <YouRang>,

You wrote: " I guess black didn't notice the back rank mate when he played 37...Qh7??"

That's the point I was addressing in my earlier post. Black got so wrapped up in trying to deal with the threat of Bxf7+ that he overlooked a second threat.

  kevin86: OOPS,I had white mating a move too early...

38...♔h8 39 ♕xf8+ ♕g8 40 ♕xg8#

The other variation remains the same

See the post from <hitman84> on the first page.

Sep-16-08  dabearsrock1010: <al wazir> your line is interesting but should have black's rook blocking on f8 and not f7

  patzer2: For the Monday September 15, 2008 puzzle solution, White's 38. Qxf7+! exploits Black's weakened back rank for a mate in two or three.
