Apr-19-06  ckr: Wood played 29.e4 dxe4. If I gave up my center pawn it would have been for the subsequent series of exchanges to simplify the position, but he doesn't instead he plays 30.h3? when 29.Rf3 clears the diagonal again and the rook can move to the g or h file. His Self-mate move instead of 32.Rf2 leads me to believe this game was very late in the tournament and exhaustion was creeping into the games. Anyone know which round this was?
Apr-19-06  United33: got it in 10 secs, yesterday puzzle is much more difficlut than this
Apr-19-06  jmuller: Gee, it's interesting reading all the sophisticated thought processes of the puzzle solvers. Back rank weaknesses and all that. Me, I just looked at the checks. First, I tried 32...Qd1+. But, I couldn't figure out a way to get rid of White's knight protecting d1. So then, I looked at 32...Qh2+. Hmm.... Gotta protect h2 with 32...Ng4 first, threatening mate. If he takes the knight with his Q, he loses the Q to black's the bishop. If, then, he takes with his pawn, aha!, he loses his Q. So, how's he gonna elimate the mate threat? Well, he could take the black Q. Ah, but then black gets mate with ...Rf1#.

It takes a lot longer to write out my thought process than it took to work through it! :-)

Apr-19-06  ianD: Too easy (nanosec)...nice move
Apr-19-06  zb2cr: Looked at it for about 5 seconds. Then had an intuitive flash that ... Ng4 was the move, threatening mate by ... Qh2 and ... Rf1. Then spent roughly 45 more seconds reasoning out the logical consequences and convincing myself. So, total of about 50 seconds. That's good for me--I'm happy when I see the solution in roughly the same time frame as a normal (slow) game.
Apr-19-06  belka: This wasn't terribly easy. White has a few loose pieces and a lack of space. His king's a bit open too. Black suffers from having too many options.

I looked for a double attack to pick up the loose rook first, and second for a way to invade into the first or second rank. Third, I searched for a discovery for the knight in order to exploit the loose White queen. And even then, I thought with the open king and active pieces, that a decoy motif would be most appropriate. It took me a bit to notice that I could play Ng4 straight away.

White's pieces are scattered on the board, his castle walls have 2 holes in them (h2,f2), and so it's not like "back rank weakness" jumps out as the likely solution.

  kevin86: I saw the solution,but it looked too easy:32...♘g4 threatens ♖f1# and ♕xh2# both cannot be stopped.
Apr-19-06  bumpmobile: I think 24. exf6 was a bad move, opening up the file for the R, but white may have been lost before that.
Apr-19-06  Stevens: <kevin86><I saw the solution,but it looked too easy:32...g4 threatens f1# and xh2# both cannot be stopped> it also threatens Qxg6 winning the queen.
Apr-19-06  Alex S.: For clarity, and because I know I struggled with what I now consider obvious when I first started doing these:

White cannot run away with:

33. Kg1

because of the rook on the f-file:

33. ...Qh2#

still occurs.

White (kinda pointlessly) delays forced mate by playing:

32. ...Ng4
33. g3 Qxg3

Threatening revealed check with the Knight, winning the Queen. More importantly, the White King cannot move.

If White plays:

34. Re1

Protecting against Rf1#, then Black plays

34. ...Nf2# or 34. ...Qh2#.

If White plays 34. Rf2, temporarily blocking the Rook, then Black need only play:

34. ...Nxf2#.

White can delay forced by THREE WHOLE MOVES (fanfare please) by playing

34. Rg2.

The force then continues:

34. Rg2 Rf1+
35. Rg1

Then:

35. ...Qxg1#

or

35. ...Rxg1#.

However, if White plays anything else, then 34. ...Rf1#.

Apr-19-06  MisterWolf: After not finding a win for White, I (like others) realized Najdorf was Black and it was his move. I didn't find the win for Black, but instead thought the move was 32...♗d8, taking advantage of White's enclosed queen. This forces 33.♕f5.

Oddly, I continue with 33...♘g4 to threaten ...♖f1# or ♕h2#. I didn't back up to realize 32...♘g4 wins outright. My line continues 34.♕xf8+ ♔xf8 35.hxg4 winning White's queen for a rook and knight. A good move, but clearly not the smitting move. :(

Apr-19-06  jmelton: What day of the week is this? Monday?
Apr-19-06  Hafen Slawkenbergius: I vaguely remember seeing in a book (I think by Chernev & Reinfeld, perhaps the one dealing with traps, pitfalls and swindles) a similar combination, in which white escaped by a perpetual, sacrificing his queen on the way. If anyone could find that game, it might be useful. BTW, this previous knowledge helped me solve the puzzle in a couple of seconds.
Apr-19-06  AlexandraThess: I found the move Ng4 in about 2.5 sec with my left eye while watching snooker on tv with my right eye!Quite an easy puzzle.
Apr-19-06  McCool: 343 this week.
Apr-19-06  sbj: I must be missing something. I'm quite the novice, but can someone please tell me where I'm going wrong here?

After:

32. ...Ng4
33. g3 Qxg3

Doesn't 34. Rf5 ruin things a bit for black? It seems like it at least delays mate for several moves (to about 38...)

  WannaBe: <sbj> if 33. g3 black would respond with QxQ (Qxg6)
Apr-20-06  EmperorAtahualpa: <I found the move Ng4 in about 2.5 sec with my left eye while watching snooker on tv with my right eye!>

<AlexandraThess> Then your left eye is smarter than your right eye. :)

Apr-21-06  AlexandraThess: <EmperorAtahualpa: Then your left eye is smarter than your right eye. :)> No ,there is a logical explanation - the TV set is on my right.My eyes are equally smart.
Apr-26-06  patzer2: White's 32...Ng4! uncovers the double attack mate threats of 33...Qh7# or 33...Rf1#. If Black tries to stop both threats with 33. g3, then 33...Qxg3 renews the threat with no way for White to prevent it.
Apr-26-06  patzer2: Of course 32...Ng4! can also be considered a discovered attack as it threatens the unprotected White Queen in addition to the dual mate threats.
Sep-02-07  wolfmaster: This puzzle did seem easier than a Wednesday puzzle.

  Paint My Dragon: <kp> You're welcome. Yes, quite an important event with several strong players.

Yanofsky and O'Kelly went on to play a smaller event in Switzerland, where they were joined by Opocensky and Pachman.

btw - I noticed that this Wood-Najdorf game has a duplicate that needs removing - all of the kibitzing is at this page, so should be straightforward.
