 | | whiteshark: Thank gof it was NZ 1962, Zygy. |
|
| May-03-10 | | randomsac: simple Qxh5 threatens Qh7# and Qh8# and after ...Bg7
30 Qh7+ Kf8
31 Q (or B) xg7#
Of course after gxh5, Bh7# opens up. |

 | | Richard Taylor: Nice game by Ortvin (originally from Estonia). I played him a few times and also Zyg once - Zyg a was very nice fellow originally from Poland. Nice finish here. |

| | Richard Taylor: <Now the Blackburne mating pattern doesn't work because f8 has been cleared with tempo. But on the way white has snaffled the h5 knight and is now a piece up. Fun little puzzle. Qxh5 screams out to be played and most of us should see it in the proverbial "less than a second", but spell checking the black defences takes a little longer.> Good points here! These defences are worth checking out. In those days I saw Ortvin analyse positions in his games from the middle games well into the ending. So he would have propbably checked out any counters here... |
|
| May-03-10 | | Patriot: 29.Qxh5 was very easy to spot since 29...gxh5 30.Bh7#--an easy pattern to remember. I thought "White wins at least a piece", without seeing <jpolchinski>'s full line ("The desperate 29 ... Qh2+ 30 Kxh2 Bd3+ 31 g6 gxh5 stops the mate at the cost of a piece.") since I briefly examined 29...Qh2+ 30.Kxh2. |

 | | scormus: Nice one for a Monday. Superficially trivial but hiding a little stumbler (29 ... Qh2+) that (not for the first time) warns us not to rush in blindly. All credit to those who saw it. |

 | | chrisowen: Say goodbye Nh5 and hello Qxh5 dos a rap you know. Black is beat lesson is drum up kingside support or till as nack would have it you cant
threaten with pieces on back of rank. Elapsing time it's getting better all the while to white. Qxh5 looks like mate honey pie helping the bishop win that entrance. |

 | | kevin86: Mondays:they make us all feel as geniuses. White gives up queen to mate-typical.As if queen sacs are common as theives. This is like a poker movie. Nobody ever wins in a poker movie with a pair of jacks-usually flushes and straights aren't even good enough.I have SEEN many poker hands won with a small pair. |
|
| May-03-10 | | jsheedy: Two seconds to see Qxh5. Two more minutes to see there's no escape with useless checks. |
|
| May-03-10 | | MJW 72: 29. QxN PxQ (If he does not take the Queen he gets mated with it.)
30. Bh7# Easy. |
|

 | | gawain: <Mondays:they make us all feel as geniuses.> You said it, Kevin. Queen sac at h5 breaks it wide open and the bishop crossfire does the trick with Bh7#. Black can put up more resistance with 29...Qh2  -but what's the point? |
|
| May-03-10 | | YouRang: White steals the knight with 29.Qxh5 and threatens Qh7#. The queen can't be taken due to 29...gxh5 30.Bh7#. Black's only option appears to be exchanging off material to relieve the mate: 29...Qh2+ 30.Kxh2 Bd6+ <enabling ...gxh5 since Bh7 is no longer mate> But even so, after 31.Be5 Bxe5 32.Rxe5 gxh5, white remains up a piece + 2 pawns (after the h-pawn falls shortly). Black should resign. |
|
| May-03-10 | | reti: Beautiful! I missed a mate like this one when I was a beginner at a tournament! |
|
| May-03-10 | | TheaN: Hm. I'm actually kinda surprised it is only now that I see that Black can safe him with 39....Qh2† 40.Kxh2 Bd6†, now either 41.g3 or Be5, but Be5 simplifies: 41.Be5 Bxe5 42.Rxe5 gxh5 wins obviously, but it is no mate. Of course, if Qxh5 already wins a piece and Qxh2† also wins the Black Queen, White has to lose a lot of material to go in deficit. Take note that an ambitious try by White to avoid this will actually lose: 40.Kf1?! Qh1† 41.Ke2 Qxe1†?! 42.Kxe1 Bxb4† 43.axb4 gxh5  is one idea, but 41....Re8†!, obviously as White is using all his pieces for the mate, 42.Kd2? Qxe1† 43.Kc2 Qxf2†  , whoops. |
|
| May-03-10 | | mworld: about the game...i got the distinct impression that black's development was going in reverse lol |
|
| May-03-10 | | rapidcitychess: Monday
Easy
29.Qxh5!
This I believe is called Blackburne's Mate. Not going into chess history, the pattern is very important. If you don't know it you can be easily tripped up. |
|
| May-03-10 | | TheBish: O Sarapu vs Z Frankel, 1962 White to play (29.?) "Very Easy", White is up a pawn. 29. Qxh5 Qh2+
Forced, since 29...gxh5 30. Bh7#.
30. Kxh2 Bd6+ 31. Kg1 gxh5 32. Re3 with the idea of 33. Be2 and 34. Bxh5. So, no mate, but White will be a piece and a pawn or two up, so Black can still safely resign. |
|
| May-03-10 | | Cushion: Qxh5 wins because of the pinned g pawn. |
|
| May-03-10 | | gofer: This one looks clear cut. A slam dunk! But things are not quite so simple for white! Mate is not on the cards, just a clear advantage! 29 Qxh5 Qh2+ (gxh5 30 Bh7# or Bg7 30 Qh7+ Kf8 31 Qxg7#) 30 Kxh2 Bd6+
31 g3 gxh5
White has won a knight during the exchange and should be able to make the king side pawn majority tell at a later stage of the game. Time to check... |

| May-03-10 | | wals: Didn't do too well with this sitter.
The eye was less quick and the brain
slower still.
Rybka 3 1-cpu: 3071 mb hash: depth 15:
Black started to slowly fade away from move:-
14...a6, +1.53. better c6 + 0.85.
Really crashed, big time:-
25...Bd5, +16.84. |
|
| May-03-10 | | turbo231: I solved Sunday's puzzle ( for the first time ) only to failed at this Monday's puzzle. One step forward and 2 steps back. Although I must say that Sunday's puzzle wasn't very hard. In that case it's one half step forward and 2 steps back. |

 | | ZUGZWANG67: 1.Qxh5 gxh5 2.Bh7 is mate. |
|

 | | Penguincw: Very close to Blackburne's Mate, per Game Collection: Checkmate: Checkmate Patterns. But the definition Schiller gives is < "One bishop gives check, protected by <a knight that covers one flight square>, while the other bishop covers the other escape squares." > Knight technically covers h7, and f7 if there weren't a pawn there. |
