Jun-18-06  harcee sarmiento: 10... Nd4 is useless. 10... a6 is a must.
Jun-18-06  harcee sarmiento: 12...Qh4? pawn grabbing with the Queen is a suicidal.

  al wazir: <Demostenes>: I also was sure that the point was to trap the ♕, but I tried a different approach: 19. Ne7+ Kh8 20. Nef5 gxf5 21. exf5, with the threat of 22. Rf4 if the ♘ on e6 moves, say, to c7.

If the ♘ doesn't move, what does black do instead? I can't think of anything very useful. In that case I plan to play 22. fxe6, getting my piece back.

But the trouble with this line is that, although the ♕ is trapped, I can't see any way to win it. Maybe someone else can.

One way to win the Fifa world cup for some countries ;-)

Never even got a sniff of today's puzzle. Still wouldn't have seen 20.Nf5 and would not have been able to keep my hands off of 20.Nxf6+.

  cu8sfan: <What's the purpose of 21...Bc3?> I think it's to clear the way for the retreat of the Black ♕.
Jun-18-06  Fezzik: I missed 21...Bc3. I got the idea of trapping the queen, but I would have been rattled by 21...Bc3. I think White's already winning there though.
Jun-18-06  Tariqov: <al wazir>19Ne7+Kh8 20Nef5gxf5 21.exf5 fails to Ng4.
Jun-18-06  itz2000: I was trying to queen trap with Nf5 :S

  kevin86: I missed this by a mile-I tried Nc7,hoping for a queen trap after Nxc7.
Jun-18-06  Shinidoki: Indeed. Nc7 was the Idea i had, followed by Bg5 and Be2....Pity it fails really.
Jun-19-06  TrueBlue: 19 Nf5 also works!
Jun-22-06  harce sarmiento: 19. Be2-Nxd5 20. Bg5-Bd4+, then white's attack is lost.

Jun-23-06  LIFE Master AJ: This is such a cool little problem, I have got to add it to my page.
Aug-09-11  ColeTrane: I believe Kaval called that maneuver as soon as black put that knight on e8, interfering w/rook communications on move ...11. Decisive, imMEDIAte action . . . practically deMANDing that black push its pawn to f4, the knight sac comes and bishop4 rook trade are the particles of residue that dissolve in an afterthought . . . . 31 ...Re8?? ... a very deep read indeed.....
Oct-20-18  Saniyat24: aha-the Phony Benoni...! Whose pun is that?
Aug-23-19  1stboard: Who needs a Rook when you have two Bishops working like that .....
Aug-23-19  mikealando: wow. nice.
Aug-23-19  catlover: It's nice to see our beloved fellow kibitzer immortalized in a game title.
Aug-23-19  Chesgambit: 19. Rxf6 is not hard move easy
Aug-23-19  Cellist: I liked the position after 19. Ne7+ Kf7 20. N3f5 f5: (or else the queen might be trapped) 21. Nf5: (You can reach the same position by doing 19. Nf5 f5: 20. Ne7+ and then 21. Nf5:) There are various possibilities here to exploit the rook's power over the f-file, royal forks, the limited mobility of the queen, and (in case of Kf7 or f8) the pin on f6. But honestly, there are too many options for me to see a clear winning path.
Aug-23-19  AlicesKnight: Missed the impact of the "quiet" g3 move after the more likely opening. A fascinating series of potential forks (use the forks, Luke, use the forks....)

  agb2002: Black threatens Ng4.

The black queen lacks mobility and the knight on e6 prevents Rf4 and Bg5. This suggests, 19.Nc7. However, after 19... Nxc7 20.Bg5 Qg4 21.Rf4 the queen escapes via e6.

Another detail is that the black queen protects the knight on f6. This leads to 19.Rxf6 Bxf6 20.Nf5 gxf5 21.g3 Qh3 22.Nxf6+ Kf7 23.Bf1 which looks winning for White.

Aug-23-19  Milesdei: I saw the first move but everything after that was beyond me, until the end, when I saw the virtuoso conclusion.
Aug-23-19  SpamIAm: Many of us woodpushers would've been content with 30.Qg5+, simplifying to a won endgame by exchanging the queens off. Kavalek's excellent 30.Be4! not only wins another pawn but pretty much ends the game right there as black's king ends up diagonally dazzled. When you see a good move look for a better one!

  patzer2: Black's decisive error is 18...Nf6?, allowing 19. Rxf6! +- which solves today's Friday puzzle.

Instead, 18...N8c7 19. Bc2 Be5 ⩲ (+0.66 @ 30 ply, Stockfish 10) keeps Black in the fight with practical drawing chances.

Earlier, instead of 13...exf5 14. exf5 = (+0.19 @ 31 ply, Stockfish 10), Black can gain an advantage with 13...Nf6 ⩱ (-0.60 @ 30 ply, Stockfish 10).
