| Sep-01-09 | | Shyfe: Shyfe: 22. Qxf7+ Kxf7
23. Bc4+
This is already won, but if black doesn't want to give up.. 23... Rd5
24. Bxd5#
Other line is:
22. Qxf7+ Kh8
23. Qxe8+ Bf8
24. Bxf8
A few lines from here but they all win easily. |

 | | gawain: I was almost quick enough! I saw what happens after Kxf7 and also the second line proposed by <Shyfe> if Black refuses the queen and retreats to the corner. Good night everyone! |
|
| Sep-01-09 | | Athamas: Black is up a pawn and threatening the bishop that is pinned to the queen. Ng5 is the first thing that came to mind but it's early in the week so I found the much better line 22. Qxf7 Kxf7 23. Bc4+
22...Kh8 Qxe8+ |
|
| Sep-01-09 | | dzechiel: White to move (22?). Black is up a pawn. "Easy."
An "easy" to find queen "sacrifice":
22 Qxf7+ Kh8
What?? Why not take the proffered queen with 22...Kxf7? Because of 23 Bc4+ Kd5 24 Bxd5#. 23 Qxe8+ Nf8 24 Bxf8 Qxb5 25 Qxb5
Not the discovered check 25 Be7+? because of 25...Qxe8. 25...Rxb5 26 Rxc8 Bxf8 27 Rxf8+ Kg7
and white is a rook and knight ahead. Time to check and see when black resigned. |
|
| Sep-01-09 | | laskersteinitz: I saw 22. Qxf7+ Kxf7 23. Bc4+, and then continued with the illegal 23...Kg8. |
|
| Sep-01-09 | | zb2cr: Found the key move(s) quickly, maybe 20 seconds. <Shyfe>, <Atamas>, and <dzechiel> do a fine job of explaining the position and winning variations. |
|
| Sep-01-09 | | dumbgai: Very easy even for a Tuesday. Unlike some puzzles, I'm fairly confident I would have found this OTB. |
|
| Sep-01-09 | | MostlyAverageJoe: < dzechiel:
22 Qxf7+ Kh8
23 Qxe8+ Nf8
24 Bxf8 ... >
White can do better. This is after 22. Qxf7+ Kh8 23. Qxe8+ Nf8 
click for larger viewand since black did not take the Q earlier, force him to do it: 24. Qxf8+! Bxf8 25. Bf6+ Kg8 26. Bc4+
click for larger viewand now the mate is unavoidable. |
|
| Sep-01-09 | | MostlyAverageJoe: PS: if after <25.Bf6+> black plays 25... Bg7, then of course: 26.Rxc8+ Qd8 27.Rxd8# |
|
| Sep-01-09 | | lost in space: 22. Qxf7+ Kxf7+ 23. Bc4+ Rd5 24. Rxd5#
Alternative: 22. Qxf7 Kh8 23. Qxe8; How to win that was out of my horizon (without a board and without a comp), but I am sure, that there is a direct win for White. Time to check and to see the solution after 22...Kh8. |

 | | An Englishman: Good Evening: If it's Monday or Tuesday, White to Move, and the f7 pawn is protected only by the Black King... |
|
| Sep-01-09 | | TheaN: Tuesday 1 September
<22.?>
Target: 1:25;000
Taken: 0:24;592
Par
Material: Black ♙ up
Candidates: <[Qxf7†]> -ML-
This is obvious, I few clear moves but the Queen sac jumps out immediately. Pretty much five seconds later I saw that it wins. <22.Qxf7†!>
/A\
<22....Kxf7 23.Bc4† Rd5 24.Bxd5‡ 1-0> so accepting is not possible, but a rejection by the King completely drops his entire army. Or at least a lot. /B\
<22....Kh8 23.Qxe8† Nf8 24.Rxc8  > and Black falls very quickly. |
|
| Sep-01-09 | | SamAtoms1980: White's light-squared bishop pins the Black knight, but the bishop is in turn pinned more forcefully by Black's queen's rook. Can the pin be broken? Let's see..... It is lightning out of a clear sky: 22 Qxf7+!!! Kxf7 23 Bc4+ Rd5 24 Bxd5 mate! It is a mate of the PURE variety, which makes it visually pleasing. If 22 ... Kh8 23 Qxe8+ and rolls. |
|
| Sep-01-09 | | zooter: 22.Qxf7+ Kxf7 (forced else Qxe8+ and mate) 23.Bc4+ mates after 23...Rd5 24.Bxd5# Shows the power of the 2 bishops and how difficult things can get if no valid interposition are available... |
|
| Sep-01-09 | | Summerfruit: Black is a pawn up.
The weak diagonal a2-g8 indicates:
22.Qxf7+!
a) 22...Kxf7 23.Bc4+ Rd5 24.Bxd5#
b) 22...Kh8 23.Qxe8+ with heavy material losses. |
|
| Sep-01-09 | | gofer: 22 Qxf7 ...
22 ... Kxf7 23 Bc4 Rd5 24 Bxd5#
22 ... Kh8 23 Qxe8+ Nf8 (not Bf8 24 Bxd7 mating) 24 Bxf8 mating Time to check... |
|
| Sep-01-09 | | goldfarbdj: Took me a bit longer to see than it should have: Qxf7+ jumped out at me, but I kept trying to follow up with Ng5+ which leads nowhere. (Black can play Kg8 and white has only a perpetual; I didn't look too hard at Kf6 trying for a win.) Then I started looking around at other things, and only rather later did I notice that white could check with the bishop instead of the knight. |
|
| Sep-01-09 | | remolino: What an idiot I am. After 22.Qxf7 Kxf7 23. Bc4+ I figured Black could play 23... Kg8 and escape to h8. Therefore I spent my time looking at 22.Ng5 or 22.Rxc1 followed by 23.Ng5. I need to have coffee before I tried to solve these. It had been a very long while since I miss a Tuesday. |
|
| Sep-01-09 | | David2009: Perhaps Black resigned too early? 22...Kxf7! hoping for a miracle, namely 23 Ng5+ |
|
| Sep-01-09 | | stacase: I'm right in there with <remolino> on this one. Duh! |
|
| Sep-01-09 | | whiteshark: An appealing <22.Qxf7+> ends the game. |
|
| Sep-01-09 | | agb2002: Black is a pawn ahead and threatens 22... Q(R)xb5. However, some dark squares near the black king are under White's control. This suggests completing that control by pressing along the light square diagonal a2-g8. Since 22.Bc4 loses miserably to 22... Rxd5, one can try 22.Qxf7+: A) 22... Kxf7 23.Bc4+ Rd5 24.Bxd5#.
B) 22... Kh8 23.Qxe8+ Nf8 (23... Bf8 24.Bxd7) 24.Qxf8+ Bxf8 25.Bf6+ Kg8 (25... Bg7 26.Rxc8+ Qd8 27.Rxd8#) 26.Bc4+ and mate in two. |
|
| Sep-01-09 | | newton296: missed Q sac , but figure Ng5 is easy win for white also so gave myself the solve ! Analysis by Fritz 10:
1. (6.93): 1...Ne5 2.Bxe8 Bd7 3.Bxd7
2. (25.73): 1...Rd8 2.Bxd8 |
|
| Sep-01-09 | | CHESSTTCAMPS: White is down a pawn, but the white forces are well-placed and cohesive, whereas key black pieces (especially Bc8 and Re8) lack mobility and f7 is weak. White's Bb5 is under attack, but white is strong enough to ignore the threat: 22.Qxf7+!
This should force resignation immediately. If 22... Kxf7 23.Bc4+ Rd5 24.Bxd5#; otherwise 22... Kh8 23.Qxe8+ Nf8 (Bxf8 24.Bxd7 wins everything) 24.d7 is a slaughter. |
|
| Sep-01-09 | | JG27Pyth: Fun. In the completely academic improvement department -- Dzechiel. I think I can improve your line: Instead of 27.Rxf8+ 27.d7! which either wins rook for pawn or the pawn promotes, meanwhile maintaining the pin on the B. |
