| Sep-08-09 | | remolino: After my suprising and embarassing miss last Tuesday I was keen on getting this right. It actually took me longer than expected (~5 minutes), but the e5 weakness and the potential energy of the R in d1 revealed themselves and so: 18.Qe5 dxe5 19.Rd8 Ke7 20.Bc5++
Time to check. |

| Sep-08-09 | | geigermuller: Full credit for me! Beautiful checkmate! I love to see how strong bishops can be. |
|
| Sep-08-09 | | stacase: There were some very well placed pawns that made this "Puzzle" work. |
|
| Sep-08-09 | | Babar47: bah , missed it :( |

| Sep-08-09 | | whiteshark: I'm still in the weekly schedule. :) |

|
| Sep-08-09 | | zb2cr: 18. Qxe5+ does the trick. If Black captures the Queen, then it's mate in two with 19. Rd8+, Ke7; 20. Bc5#. Black's only alternative is 18. ... Be7; 19. Qxh8+, Bf8 when White is up by a Rook. |

Target: 1:25;000

Par
<18.?>
Material: =
Candidates: Qc6†, Bd7†, Bxc8, <[Qxe5†]> -ML-
The main line is easily Tuesday, but the sublines seem more difficult. In the end, they just win material without any compensation for Black. White wants a breakthrough, with the well positioned light squared Bishop and d1-Rook. White breaks through in the most brutal form. <18.Qxe5†!!> ouch. Upon playing this move, White should at least know what to play when Black captures. /A\
<18....dxe5 19.Rd8† Ke7 20.Bc5‡ 1-0> and this is a humiliating mate, with all the White pieces sneaking away from the Black pieces, that are numerous on the board, but all unable to help. This is the main variation. I got kinda stuck on the two interpositions. Definitely bad is: /B\
<18....Be7 19.Qxh8† Bf8 20.Qe5†  > and White repeats the position a Rook up. Now, every option to cancel Black counter play is available, as White already has the material. Slightly less obvious is: /C\
<18....Be6> this removes all mating threats as the Rook on a8 comes into play. White wins after: <19.Qxh8> ...but might still have the obligation of countering Black's counter. It is only due to the placement of the White Queen on the a1-h8 diagonal that this counter play is not too much. <19....Qa3† 20.Qb2 > and although still a bit unbalanced, White should win easily. Time to check. |

 | | LIFE Master AJ: 18.QxP/e5+! The only question is when does Black resign? |
|
| Sep-08-09 | | Eisenheim: Have to admit, this took me way longer than usual. If you played Tal-like and considered the Queen sacs first, or if this was a Monday puzzle where I look for the Q sac first then it would've been easier. I was initially trying to take advantage of the Black isolated Queen, and thought about windmilling the rook to a5, which was too slow. Then I considered dislodging the C bishop to try and promote and concluded that takes too long for a Tuesday. Finally, I concenred the FORCED moves. I capitalize that, because the forced moves really do dictate play, and should always be considered no matter how foolish they look on the onset. Once I did that, I immediately siezed the right move, called myself a moron three times and now am running late for my boat to work. du-oh! |
|
| Sep-08-09 | | gtgloner: 18. Qxe5+ de 19. Rd8+ Ke7 and then 20. Bc5#. Black is caught in the White bishop's crossfire. Let's see. |
|
| Sep-08-09 | | johnlspouge: Tuesday (Easy):
N Fercec vs B Medak, 2000 (18.?) White to play and win.
Material: Even. The Black Ke8 has 1 legal move, e7. Forward examination of forcing candidates reveals a mate threat that wins material, so further analysis can be based on the candidate. Candidates (18.): Qxe5+
18.Qxe5+ dxe5 [Be7 19.Qxh8+ wins material and prevents Qa1+] 19.Rd8+ Ke7 20.Bc5#
I love Mondays! |
|
| Sep-08-09 | | johnlspouge: In my glee, I missed the defense 18.Be6. |
|
| Sep-08-09 | | Patriot: 18.Qxe5+ is crushing due to 18...dxe5 19.Rd8+ Ke7 20.Bc5# as in the main line. Other moves like 18...Be6 or 18...Bd7 lose to 19.Qxh8. <stacase: Puzzles and Queen sacrifices. This one fell apart after a short search. Over the board? Not a chance!> Hey why not? If you train yourself to look for checks, captures, and threats on each move then finding something like this OTB shouldn't be hard to do. <TheaN> Your variation C has one problem: After 18.Qxe5+ Be6 19.Qxh8 Qa3+ 20.Qb2, black has 20...Qxe3+ so 20.Kd2 looks better and if 20...Qa5+ 21.Qc3. |

Having seen it, I could not wait to search for a tactical candidate, even at the cost of not finishing my analysis! I doubt now that I could avoid the same reaction over the board. |
|
| Sep-08-09 | | Patriot: <johnlspouge> Once I saw how crushing 18.Qxe5 is, I don't think I would spend much time looking for anything better unless it's immediately apparent. Out of curiousity, as black would you have discarded 17...Qxa4 as a candidate because you see that it loses to 18.Qxe5 and decide on something like 17...f5? |
|
| Sep-08-09 | | lost in space: Found it quickly:
18. Qxe5+ dxe5 19. Rd8+ Ke7 20. Bc5# |
|
| Sep-08-09 | | fab11mt: Is 13. Qxc3 not questionable, in as much he loses a piece, while 13. cd7+ evens out and the pawn on c3 could be recaptured after the pawn on d7 have been taken? |
|
| Sep-08-09 | | cyclon: 18.Qxe5+. |

| | LIFE Master AJ: <<johnlspouge> "I love Mondays!"> UH ... isn't today Tuesday ... or is my computer broken? |
|
| Sep-08-09 | | ZUGZWANG67: I think W wins a whole R with 18.Qxe5+ Bxe6 (18. ...dxe5 19.Rd8+ Ke7 20.Bc5 mate) 19.Qxh8, as after 19. ...Ng7, W can consolidate by 20.Bd4. Time to check! (GULP!)

That was it, but Medak played it right to the end... |

|
| Sep-08-09 | | Milesdei: Saw it immediately. Two for two so far this week, but both puzzles were elementary, in my humble patzer opinion. Seems that Black could have held out a bit longer by declining the sacrifice, as noted above--but White wins regardless. |
