| Apr-02-13 | | morfishine: Its over in 3-moves: 33.Qxh7+ Kxh7 34.g8=Q+ Qxg8 35.Rh3# |
|
| Apr-02-13 | | agb2002: White has a bishop and a pawn for a knight.
Black threatens 33... Qxh5 and also to take the pawn on g7 eventually. This pawn is a shield for the black king. Therefore, eliminate it with 33.Qxh7+ Kxh7 (33... Kf7 34.g8=Q+ Kf6 35.Bg5#) 34.g8=Q+ (34.Rh3+ Kg8 35.Rh8+ Kf7 36.g8=Q+ Qxg8 37.Rhxg8 (threatening mate in two) 37... Nf3+ - +) 34... Qxg8 35.Rh3#. |

| Apr-02-13 | | shaikriyaz: a double queen sac! |
|
| Apr-02-13 | | stacase: <Phony Benoni: Guess that makes up for Monday; we have a double-queen sacrifice!> First chuckle of the day |
|
| Apr-02-13 | | Abdel Irada: <FSR: Well, I guess it's slightly important in preventing ...Kh6, although Black loses even if that were possible.> It could be said, in a sense, that it's important in making today's puzzle "easy" rather than "medium-easy." ;-) |
|
| Apr-02-13 | | zb2cr: Found this quickly. For trenchant commentary on this puzzle, see above, <Patriot>, <Bartimaeus>, <M.Hassan>, <FSR>, <Sneaky>, <Abdel Irada>, <morfishine>, and <agb2002>. Between them, they have covered the waterfront as far as comments go! |
|
| Apr-02-13 | | TomOhio: There are numerous mates here... but here's my favorite: 33. Qxh7+ Kf7
34. g8(Q)+ Kf6
35. Qh6+ Qg6
36. Qgf8+ Rf7
37. Qxd6+ Ne6
38. Bg5#
So, Black has two pieces that could take White's mating piece... except that they are both pinned. AND, there were three consecutive forced interpositions, none of which saved Black from his fate. |

| Apr-02-13 | | lost in space: Back from vacation. Got this one here quickly. |
|
| Apr-02-13 | | Alex56171: I followed the same line as <M.Hassan> did. The game line is quicker and more elegant. |

 | | Phony Benoni: <Bartimaeus> Finding the similar position to yesterday's puzzle was a matter of recollection; it was a familiar example. In general, this database can be searched by position only through the Opening Explorer. The games can be downloaded into a outside system which performs such searches, though there is no quick-and-easy way of doing that. |
|
| Apr-02-13 | | Bartimaeus: <Phony Benoni> That's good memory :) Thanks for the info. |
|
| Apr-02-13 | | Nick46: Nice work TomOhio; your solution is better than the one given, in that it extends the loser's life-span. |
|
| Apr-02-13 | | mistreaver: White to play. Tuesday. Easy. 33?
The queen sacrifice is fairly obvious:
33 Qxh7+ Kxh7
Here i instantly played the following:
34 Rh3+ Kg8
35 Rh8 "mate", forgetting that here after
35 ... Kf7
36 g8Q+ Qxg8
37 Rxq8 there still has some play in the position (altough even here the threat of Rg7 looks deadly).
On taking a breath i discovered more clear cut way to end this:
34 g8Q+ (diverting the queen and forcing her to block the g8 square)
34 ... Qxg8
35 Rh3 mate
Time to check.
------
2/2. |

| Apr-02-13 | | TheTamale: Can be solved via logical processes. Must start with a forcing move by the queen, else she gets picked off with check. But following up by a rook check allows the Black king to escape. So the pawn must be pushed to prevent it. Then rook swings over, and it's good night Irene. Simpler than the proof of the so-called Archimedian property! |
|
| Apr-02-13 | | whiteshark: I think a 'little trap' (temptation) lies in 33.Qxh7+ Kxh7 <34. Rh3+? Kg8 35.Rh8+ Kf7> after which 
click for larger view followed by <36.g8Q+ Qxg8 37.R1xg8> (not 37.R8xg8 Nf3+ fork), when I don't see any mates on the horizion. |

 | | LIFE Master AJ: 33.QxP/h7+ and mate in two moves. (Got it pretty quickly too.) One thing I have noticed is that - when you KNOW there is a solution there - you tend to get it. However, I have lost track of the number of times (in tournaments) when there was a relatively simple tactical solution ... and I failed to get it. Of course in tournaments, my back may be hurting, I may be short of time ... or maybe a half dozen other factors, all of which have the possibility of affecting your play. 
click for larger viewThis was from my last tournament.
The position is:
K. Potula - A.J. Goldsby
(Black to play his 28th move.) I will post the PGN score on my player page, if you are curious to see what happened.) |

from lack off h6 in dreading of rookf6 and d4 wont,
it save her I be proof in h6 light undermines it so win conduit g8 in you beck and call it is see on demand you bagger in rites it sage in reign com pour 34.g8Q+ when f6 light wraps it up lid evermore, win prom 34...kf6 choice in g5 or get it is stuck in er cached on core g5 one lined 35.qh4 off anyone get deja vu? |
|
| Apr-02-13 | | kevin86: Funny,the only thing stopping the mate was white's own advanced pawn-easy solution:make black eat it. So white sacrifices TWO queens to mate with two rooks. |

| | LIFE Master AJ: Its actually a fairly well played game ... I like it. |
|
| Apr-02-13 | | psmith: <whiteshark>: In your line, 38. Rf8 Kg7 39. Bh6# is a mate on the near horizon which can only be averted by giving up a rook. Of course, the game continuation is better! |
|
| Apr-02-13 | | silly patzer: <psmith>36.♖f8+?? ♕xf8! |
|
| Apr-02-13 | | thegoodanarchist: Don't Russians have an old chess saying that is roughly translated, "Good thing you were checkmated, otherwise you would have lost your queen!" |
|
| Apr-02-13 | | jonnyjack: it seems like 31. Qh5 is a blunder, since hxg7! is possible right away at move 31 for white. If black plays 31...g6 black should be fine. |
|
| Apr-24-13 | | psmith: <silly patzer> I didn't say "36.Rf8+"... I said "38. Rf8+"... The point was that after <whiteshark>'s 33.Qxh7+ Kxh7 34. Rh3+? Kg8 35.Rh8+ Kf7 36.g8Q+ Qxg8 37.R1xg8 White threatens mate in two so there is a "mate on the near horizon..." which can only be met by giving up hordes of material. |
