Apr-29-07  MostlyAverageJoe: I had no clue here. Depressing. Oh, well, time to pick inaccuracies in the game to make myself feel better. All valuations as per HIARCS 11.1, not particularly deep.

Blunder: 21. ... Nd7? (exf5 followed by Ne6 is about 4 pawns better)

Huge blunder: 22... fxe6?? (Ndxf6 was about a queen-worth better)

White returns the favor: 24.Bxg6+?? (Qxh7 was a queen+minor piece better)

More returns: 25.Qh4+? (Bf5 was about a minor piece better).

And more: 30.Bxg6? (Qg7 was another minor piece better).

Now black reciprocates: 30 ... Rad8??? (enables forced mate in 5: 31. Qh4 Qc4 32. Qxc4 Nc5 33. Qe2 Kf4 34. Rf1 Kxg5 35. Qh5#). Qa7 was better.

But white does not want to mate yet: 31.Qg7+?

However, black wants to end his suffering: 31... Kf4 (Rf6 was better)

And now the white obliges.

The entire thing started, of course, with 19 ... Bxf7 insead of Ne8.

Apr-29-07  Manic: I got 21.Nf5 but I did not consider the Nd7 defence. If I did, it was probably 50:50 chance that I would see 22.Rxe6!!
Apr-29-07  MORPHY MARVELLOUS: To all the people on here who said they got it, do you mean you got every single move or just first couple, because if its the latter, then my friends you didnt get anything I'm afraid.
Apr-29-07  ForeverYoung: Looking at this position it isn't difficult to see that if the Knight on e8 could be removed then black would be for it. I found 21 Nf5 and had 21 ... gxf5 22 Bxf5! exf5 23 Rxe8! planned.
Apr-29-07  tallinn: Pinter will never tell us but for all those (including me) that did not see the Nd7 defense let's assume that Pinter did not see that either when playing Nf5. After all the position after Nd7 does not look overcommitted to white. He probably spend considerable time after Nd7 to find the best move (Ne7+ Kh8 Bxg6 wins as well here). He managed to find Rxe6 but got exhausted then as Joe pointed out. So the puzzle could have started a move later as well :-)

And Fritz thinks that exf is superior to Nd7 making me not to notice Nd7 until I checked the solution. So what? It is sufficient to see that Nf5 cannot be taken. It is such a wonderful place for the knight one must play it.

Apr-29-07  scholes: 21. Nf5 Nd7 22. Rxe6 fxe6 23. Ne7 Kf7 24. Bxg6 Kxf6 25. Qh4 Kg7 26. Qxh7 Kf6 27. g5 Ke5 28. Bxe8 Be4 29. Ng6 Bxg6 30. Bxg6 Rad8 31. Qg7 Kf4 32. Qd4 Kxg5 33. Rg1 Kh6 34. Qh4 Kg7 35. Be8 Qg3 36. Rxg3 Mate 1-0

mate only comes at the 36 move ,in between white gets ahead on material only on move nor 35 when black has to give queen to prolong the mate.So how much do these gm calculate in these type of kinghunts.Can they really calculate this far in such a complicated situation and how far is good enough

Besides that pinter could have won faster at several places for example bishop sac was not necessary

  Richard Taylor: I thought I had solved this with Nf5 and missed Nd7 as a defence. But I would still have played Nf5 as I cant resist such moves...sound or not!

  paulalbert: The ideas are easy enough to spot with g7 as a focal point for mate, but visualizing the right sequence and all the defensive resources is way beyond my abilities. Nd7 as a defensive resource seemed counterintuitive to me because it cut off potential defense of g7 by Black's Q, but threatened the Pf6 bone in the throat. I was looking at Bxg6 ideas and possibly Nxe6 as well as Nf5 ideas followed by Rxe6, but once you see it, Nf5 first is the way to go. I've played something like this as a speculative sac in blitz, but am not confident in serious play, because I can't see to the end. Paul Albert
Apr-29-07  outplayer: I saw 21.Nf5 but I didn't calculate this on. Very hard.

  playground player: Gosh, this was amazingly easy for a Sunday puzzle, I solved it in no time flat... and don't I wish a single word of this was true!
Apr-29-07  Crowaholic: Very tough stuff, worthy of a Sunday. I finally figured out that Nf5 is pretty strong, but I didn't get Rxe6.

Regarding the continuation: After 24. ♕xh7+ ♔xf6 25. ♘xg6!!, Black would have been forced to drop the Q with 25. ..♕f4+ 26. ♘xf4 to prevent g5+ ..♔xg5 ♕h4#.

Apr-29-07  brainof7: can someone explain why are Nf5, why black cant take with the g pawn?

  Peligroso Patzer: <brainof7: can someone explain [after] Nf5, why black can't take with the g pawn?>

If 21. ... gxf5, White plays 22. gxf5, and the opening of the g-file creates unstoppable threats. There is nothing immediately forcing that leads directly to mate, but the following line is representative of how play might continue: 21...gxf5 22.gxf5 Bg2 23.Rg1 Qc6 24.Rd2 Nd7 25.Rdxg2+ Qxg2 26.Rxg2+ Kh8 27.fxe6 Ndxf6 28.Qxf8+ Ng8 29.Rxg8#.

Apr-29-07  Timex: Man, this was hard for me. I guess I am not as smart as some users. I only saw Nf5, and Rxe6 after that, but that took a while.

  fm avari viraf: It's easy to find the move Nf5 as Black dare not capture it either with e-pawn or g-pawn & if he does his King would be in graveyard very soon. But to spot Rxe6 is indeed very difficult. The whole combination is simply sterling & beautiful.
Apr-29-07  Chess Classics: I've stopped trying too hard on Sundays, because I never get them. This week is no difference =)

Apr-29-07  Skylark: I found the move and the winning lines against ex and gx, however I neglected to observe possible declined lines (I didn't see Nd7 protecting the rook) - no long comment here, just missed the other defense. The computer can say that exf5 is better than Nd7, but those things can find crazy defenses in such positions, whereas humans on the other hand..
Apr-29-07  Marmot PFL: The Nf5 idea isn't hard to find if you've read Art of Attack or Sacrifices in the Sicilian. Of course the GM followed it up with more precision than I would have, but maybe a strong program would win even more quickly. This is a classic computer type position.
Apr-29-07  cyruslaihy: I thought this is a monday puzzle (its monday morning here in Hong Kong), when i found i can't solve it, i'm terrified to death!
Apr-29-07  kewlmodee: brainof7: can someone explain why after Nf5, why black cant take with the g pawn?

If 21. ... gxf5, White plays 22. Bxf5 (Threatening mate) then, exf5. 23. Rxe8 then mate inevitable with 24. Qg7#

Apr-30-07  concreteengineer: I actually got the correct move for a Sunday puzzle. Of course, it really only counts if you also get the followup and I did not see Nd7. But it is Sunday, and I'll take what I can get.

  kevin86: I like how the white pieces play "ring around the rosie" with black's king.
May-01-07  Rubenus: A very impressive combination!

  kevin86: I like white's gymnastic moves against an opponent with a gymnastic name-lol
May-31-12  MarkFinan: White makes some work of finishing black off here after offering the knight sac on f5, but he's brave and has total conviction in his plan..

I also notice no-one's looked at this game with an engine or kibitzed here for 5 years..

I'm sure they must be either some defence for black, or a quicker finish for white? Exciting, attacking, game which ever way you look at It :)
