| Jan-18-07 | | greensfield: Started out with the four forcing candidate moves:-
17. Qxd7+, Nf6+, Nc7+, Rxe5+.
Thought I'd cracked it with the first one
17. Qxd7+ then
17...Bxd7 18. Nf6# (17...Qxd7 18...Nf6#)
but (17...Kxd7 drat)
Soon rejected next two 17. Nf6+ Nxf6 and 17. Nc7+ Qxc7 as Black has winning advantage Last one Eureka!!
After 17. Rxe5+ black has 3 options
(a) 17...dxe5 18. Nf6+ Nxf6 19. Rd8#
(b) 17...Nxe5 18. Nf6#
(c) 17...Be7 18. Rxe7+ Kf8 19. Qf5<(threat Qxf7#)> Ne5 20. Qf6<threat Qxh8#> Rh7 21. Re8+ Kxe8 23. Qd8# |

| Jan-18-07 | | rochade18: Strike! |
|
| Jan-18-07 | | Snaeulf: got it quite quickly |
|
| Jan-18-07 | | tatarch: Thank you whatthefat |
|
| Jan-18-07 | | medjutim: Another one from the games where player plays his move and resigns..
Nevertheless, an easy one again.. Funny thing, I wasn't sure for some time, because I didn't see that after 17...Nxe5 18. Nf6# black has no place to move his king :) |

 | | keypusher: Wow, how pretty! |
|
| Jan-18-07 | | kevin86: It's funny,the knights certainly showed a lot here,but I missed what a little line-opening move or two really decided this one in a hurry! Black resigned because of 21 ♖e8+ ♔xe8 22 ♕d8#. It's funny,or is it kismet,that in a few other variations ,mate comes at d8,albeit with another piece! |
|
| Jan-18-07 | | alphee: completely missed this one as I did not see 17: ... ♗e7 but just 17. ♖xe5+ dxe5 18. ♘f6+ ♘xf6 19. ♖d8# and that was too easy! |
|
| Jan-18-07 | | Fisheremon: <whatthefat: <tatarch> The database has 20 games with 10.Bxb5, the two earliest being from 1973: A Vitolinsh vs L Gutman, 1973
Tal vs M Stean, 1973
I'm not sure which of those came first. 11.e5 here appears to be a novelty though, with it being repeated in F Hellers vs Igor Ivanov, 1992 where Black won.> The similar idea with sac 10.Bxb5 was first met in
Bronstein vs Najdorf, 1954 |

 | | Peligroso Patzer: <tatarch: Maybe a premium member or opening guru can tell me actually--is 10. Bxb5 standard?> IM Richard Palliser's book, Starting Out: Sicilian Najdorf, describes 10. Bxb5 as a "standard sacrifice for the initiative" (p. 173). The 10. Bxb5 line is the subject of illustrative game #44 in that book (pp.178-180). |
|
| Jan-18-07 | | TrueBlue: got it. But it was quite tricky. Rxe5 wasn't the first move I considered. I first tried fxe, but coudn't get enough advantage. |
|
| Jan-18-07 | | wasspwot: thanks for more superb computer analysis of the type that was so helpful in the Arno Nickel game. |
|
| Jan-18-07 | | simsan: I rather quickly saw the two mates that follow from 17.Rxe5+ dxe5 and 17. Rxe5+ Nxe5, and I realized two things:
a) Rxe5 had to be the right move and
b) (with yesterday's puzzle in mind) There were other defences that made things more complicated.I then saw that after 17. .. Be7 18. Rxe7+ Kf8 mate seemed a little more difficult. Sadly I didn't really crack that challenge.
I settled for 19. Qc3 which (according to my computer) is only the third best move. 19. Qc3 is however clearly winning (toga: +16 after 13 ply):
a) It directly threatens Qxh8#
b) It threatens Rde1 (doubling the rooks) followed by Re8# (to which black can basically only reply by moving his N loosing his Q to Rxb7)
c) It protects the N at c6
d) It avoids a discovered threat to my Q from the bishop on c8 Black's position is in ruins, and he will go on to loose a lot of material including his Q or get mated within the next couple of moves. Admittedly the text move is # in 5
.. and 19. Rxf7 is apparently # in 11 (which is probably obvious to some ppl :-) ) |
|
| Jan-18-07 | | YouRang: I found it fairly quickly when I considered that Nf6+ would be mate if not for ...Nxf6. This means that I can *force* ...Nxf6 by playing Nf6+. Does that do me any good? Not quite. However, I could then deliver the familiar N+R mate (Rd8#) if only the d6 pawn were out of the way. Can I get rid of the d6 pawn? Yes! 17. Rxe5+! If 17...dxe5, I spring the trap: 18. Nf6+ Nxf6 19. Rd8#. (Of course, if 17...Nxe5, then I've deflected the knight allowing the immediate 18. Nf6#). Of course, 17...dxe5 isn't forced, but his only other choice is to surrender a bishop: 17...Be7 18. Rxe7 Kf8, and now after 19. Qf6, white's attack is in full swing. I didn't see all the way to mate (which is just a couple of moves away as it turns out), but I could 'smell' it. :-) |

| Jan-19-07 | | Fisheremon: <RandomVisitor: Did White miss an earlier win at move 14: 15-ply
(1.91): 14.Nxe6! fxe6 15.Rxe6+ Kd8 16.Rxf6 Nxf6 17.Bxf6+ Be7 18.Bxh8 b4 19.Nd5 Rxa2 20.Nxe7> Right, but 20.Qe4 seems better. Here some comments: strikingly after 11...Qb8 Black's position was lost (poor Black didn't realize the nuance of the sac: 11...Qb8 just played in the case 11.Ndxb5, and perhaps 11.e5?! because of 11...Bb7, or 11...dxe5 12.Ndxb5 Qb7 13.fxe5 Rxa2 with equal chances). After forced 12.exf6 gxf6 13.Rhe1 h5 White has a variety of ways to get advantage 14.Qh3, 14.Nxe6, 14.Ncxb5, 14.Nc6 the first two lead to a clear win. A comparison between them. In many variations 14.Qh3 leads to beautiful mate attacks, 14...e5 seems to be the best resistance (14...Be7 could be also, still with a lost endgame) 15.Nd5 fxg5? Black decided to take poisoned Bishop that led to the forced mate. Instead 15...Bg7 could avoid it, still losing. Conclusion: 14.Nxe6 is the best continuation for attack. |

|
| Nov-24-22 | | Brenin: No deliverance for Black in this game. |
|

 | | Teyss: Impressive game, no less than five sacs in 20 moves:
10.Bxb5 even if the piece is regained 2 moves later.
13.Rhe1 take my Bishop.
14.Qh3 same.
15.Nd5 c'mooon.
17.Rxe5+ probably the most beautiful. Was a Thursday puzzle in 2007.
Would have been six if Black hadn't resigned before 21.Re8+.The pun, is it a reference to Dueling Banjos? |
|
| Nov-24-22 | | goodevans: Black never fired a single shot in this dual. It must have taken an iron will to resist the temptation to play 11...Bb7. |
|
| Nov-24-22 | | nalinw: Nice on <Brenin> ..... the Dueling Banjos scene was so brilliant |
|
| Nov-24-22 | | goodevans: <Teyss: Impressive game, no less than five sacs in 20 moves:
10.Bxb5 even if the piece is regained 2 moves later...> 10.Bxb5 is a genuine sac if, as is usually the case, Black plays 10...Bb7. The Opening Explorer has 14 games with the position after 11.e5 Qb8 12.Ndxb5 Qb8 13.Qe2 dxe5 14.Qc4 (some via transposition of White's 11th and 12th moves). Score +6 =7 -1 to White. <... Would have been six if Black hadn't resigned before 21.Re8+.> Shame on Black. If you're that close to being mated in such wonderful fashion then I think it's only good manners to let it play out. |
|
| Nov-24-22 | | ChessIsLife159753: 17.Rxe5+!! is the real stunner. Black is mated shortly after 17...Nxe5 18.Nf6# or 17...dxe5 18.Nf6+! Nxf6 19.Rd8#. The rook sac had the purpose of opening the d-file (variation 2) or deflecting the knight (variation 1). |
|
| Nov-24-22 | | Amarande: The mate after 17 ... Nxe5 18 Nf6# is a nice one. We were always told it was best to develop one's knights to QB3 and KB3. Even better if it's your opponent's QB3 and KB3, apparently! |
