|Aug-24-06|| ||dzechiel: <NakoSonorense: What if Black decides not to take the knight?> Well, the immediate threat is 19 Nd6. However, if black isn't careful, white could play 19 Qe6 with the threat of 20 Nh6+ Kh8 21 Qg8+ Rxg8 22 Nf7#.|
|Aug-24-06|| ||tallinn1: Fritz 8 decided not to take the knight. The game continued as follows (white: tallinn, black: Fritz 8):|
1. Nxf7 Rf8 2. Nh6+ Kh8 3. Bg5 Ne5 4. Bg4 Qe8 5. f4 Nxg4 6. Qxg4 Bc8 7. Qh4 Ra7 8. Bxe7 Rxe7 9. Rxe7 Qd8 10. Rde1 Bd4+ 11. Kh1 Bf6 12. Qxf6+! Rxf6 13. Re8+ Qxe8 14. Rxe8+ Kg7 15. Rxc8 Rxf4 16. Kg1 Rf8 17. Rxf8 Kxf8 and white is a piece and a (passed) pawn ahead so clearly winning.
|Aug-24-06|| ||dakgootje: The sac itself wasnt too hard, quite common, but i had a hard time finding d6 as a move. think that was the hardest part of the puzzle by far as it is a more or less silent move in an attack while a piece down|
|Aug-24-06|| ||WarmasterKron: The sac was fairly obvious, and I saw the idea of d6, but I'd missed 19.Qe6+. Can I have half a point?|
|Aug-24-06|| ||eblunt: <aw1988: A tougher defense might be Nxf7 Nf6...> Yes, at least protects against the N fork on D6, and opens up the Black Q diagonal to protect e6|
|Aug-24-06|| ||eblunt: That b6 pawn looks horribly weak as well. Even if black scrapes a defense together on the K side, Na4 and the queenside falls apart. That's just such a horrible, uncoordinated black position. I should know, that's how my position always seems to end up|
|Aug-24-06|| ||EmperorAtahualpa: I just knew these had to be the right moves, but I didn't know what to do after 19...Kf8, so as far as I knew it could just as well have been a spoiler.|
|Aug-24-06|| ||EinZweiDrei: <EmperorAtahualpa> - Same.|
|Aug-24-06|| ||Halldor: Excellent puzzle! The difficult move to find here is 20. d6! I got it because I saw that 20...exd6?? didn't work. There were more candidate moves there but I liked 20. d6! - it had somehow a nice style for a puzzle... Saw the continuation until White's 23d move (thought it would be 23. gxf3).|
|Aug-24-06|| ||Mendrys: Only partial credit for me. I too found the position screaming for a knight sac on f7. I calculated up to 20. d6 but went no further.|
|Aug-24-06|| ||builttospill: This is a first for me. Got every move 18-23.|
|Aug-24-06|| ||thirdeye: I found Nxf7 but instead of 20. d6 my idea was Ne4 threatening Ng5 and Nd6. The best defence for black seems to be 20... Ne5 which allows white to win back the piece with Bxe5|
|Aug-24-06|| ||Parriotblue: What about 20.d6 Ne5? Is this line more difficult for White?|
|Aug-24-06|| ||kevin86: What a bizarre ending!! Black is up a piece-but has no moves. What follows after 27 ♖d8 shouldn't happen to a dog!|
|Aug-24-06|| ||Major Dude: "What a bizarre ending!! Black is up a piece-but has no moves."|
Black is NOT up a piece but down an exchange. Rd8 isnot necessary as the the R on e8 can simply capture the QKnight right away.
|Aug-24-06|| ||YouRang: I missed rather widely -- seemed pretty hard, even for a Thursday. :-(|
Still, a thoroughly enjoyable puzzle, with an amusing end position.:-)
Materially, White won the exchange and a pawn (and the knight at b8 appears to be short-lived). But positionally, and more importantly, Black has simply been shut down, almost single-handedly by the white rook!
|Aug-24-06|| ||wharfrat: <Parriotblue> 21.dxe7+, Rxe7; 22.Qxc8+, Bxc8; 23.Bxa8 is completely winning for White, particularly as Black cannot play 23...Nxc4 because of 24.Bxb8.|
|Aug-24-06|| ||kevin86: <Major Dude> you are correct on both accounts. What is really bizarre is that a lone rook can tie up four pieces.|
|Aug-24-06|| ||babakova: As soon as I saw d6 as a follow up I knew Nxf7 was the correct move.|
|Aug-24-06|| ||HoopDreams: i saw nxf7 kxf7 qe6+ kg8 then d6 with 1 minute of analysis, before puzzles used to be hard but i guess studying tactics helps out :)|
|Aug-24-06|| ||scorpius: This one is so intuitive, the only move that you have to see to know it's right is 20.d6|
|Aug-24-06|| ||GoldenKnight: <scorpius> Agreed.|
|Aug-24-06|| ||aazqua: d6, which some have said is hard to find, is actually completely unnecessary. n8p, k*n, and then the quiet b-g4 is sufficient. white has myriad threats, the simplest of which is b*n r*n followed by qe6 ch and q*n with a winning game. white is so far ahead in development and black's king on such shaky ground that fireworks like d6 are unecessary. Nice game by white, a good lesson for black in neglecting development and conceding space.|
|Aug-24-06|| ||shortsight: <aazqua> I don't see how you back up your points by claiming Bg4 is sufficient without any concrete variations to show.|
The point why the rest are saying that d6 is the harddest move is because it turns the game around so much that from a merely + position into a stunning crush of black fortress. I'm also impressed with the White Q series of checks to force the black K into h8, and crippled all of black pieces, they end up waiting to be captured by White.
|Sep-03-06|| ||patzer2: The demolition of pawn structure combination 18. Nxf7!! proves to be White's decisive blow.|
I must confess these demolition combinations are much easier to find as a puzzle solution at chessgames.com than OTB. Also they take more courage to execute OTB under time pressure, and without the suggestion that one side has a brilliant win involving a sacrifice as a solution to a chess problem.
