| Mar-01-13 | | mistreaver: Friday.Black to play. Difficult.31.?
At first sight the move that seems like solution would be:
A)
31 h3
now black has two choices
A1)
31... Kxh3
32 Ne3+ Kh4
33 Ng2+ Kg5
34 Qf5+ and now both
34... Kxg6 or 34... Kf6
lead to
35 Re6 and mate,
and 34... Kh6 is met by
35 Qh5 mate
A2)
31... Kg1 seems more logical
32 Qb6 (in order to gain a tempo for Re1)
32... Rd7
33 Re1 Qf1
34 Rxf1 and i think black should win this
Time to check.
-------------
Ooops, i missed the strong Qc4+ (after Qb7) when it is not white who wins, but black. Totally missed the significance of Nxg3, well, too bad, but i have to give myself half a point for precisely calculated first line, and seeing the right idea, only missing the correct interpretation. Therefore 4/5 this week. |
|
| Mar-01-13 | | orezrg: <Phony Benoni> Thank you (confess catastrophic error for my part) |
|
| Mar-01-13 | | mistreaver: I should also like to add that instead of Nxg3, d3 also wins, since white is too tied up to do anything about fast running d pawn |
|
| Mar-01-13 | | Abdel Irada: <<•>The Art of Misdirection<•>> Black has attacked White's bishop with a pawn, but White is willing to let him take it, secure in the certainty that with four pawns for a knight and an active rook on the seventh, he will retain all the winning chances. But White is in for a surprise, for Black never intended to take the bishop; he has a taller target in his sights. <<•> 31. ...h3† > White has two plausible replies, although one is only superficially so. < (1) 32. Kxh3?, Ne3†
33. Kh4, Ng2†
34. Kg5, Qd5†  >
Black mates within three moves; e.g., 35. Be5, Qxe5† 36. Qf5, Qxf5† 37. Kh6, Qh5#. <<•> (2) 32. Kg1, Qe1†33. Qf1, d3 >
White will have to give up his rook to stop the pawn, since 34. Bf4 will be met by 34. ...Nh4 followed by 35. ...Nxf3† with mate to follow. The finish might be 34. Rd7, d2 35. Rxd2, Qxd2 36. Qc4†, Kh8, and White, a rook down and out of useful checks, must /upgivvet/, for at the end of any combination he might try lies the ineluctable back-rank mate. |

| Mar-01-13 | | newzild: <mistreaver> I fell for the same line as you. I blame the third can of Guinness! |
|
| Mar-01-13 | | Kiril Simeonovski: This is an easy one, but after 31... h3+ 32. Kg1 Qe1+ 33. Qf1, Black cans also play 33... Qd2. |
|
| Mar-01-13 | | Abdel Irada: <I blame the third can of Guinness!> Guinness in a can is so watered-down, I'm surprised it would have any effect. The "Extra Stout" in bottles *used* to be significantly better (an actual extra stout), but recently the company has apparently decided it was giving its customers too much for their money. One might call it a victim of its own success. The truth is, if you want a good bottle of beer, you're essentially forced to buy a microbrew. Fortunately, there are more of these all the time, and they're getting better and more affordable. As for Guinness, it's coasting on a reputation that it no longer deserves, and it does so by subtle but deliberate deception. Begin with the front label. As I recall, it says "Traditionally brewed in Dublin, Ireland," or something very like that. This invites the buyer to think that the beer is brewed according to traditional methods in Dublin. To see the less romantic reality requires a trip to the back of the bottle, where the second label says the beer is a product of New Brunswick, Canada. Now the real meaning of the legend on the front takes shape: The beer *was* traditionally brewed in Ireland, but that tradition is now invoked only by way of fostering a misleading image; it is *now* mass-produced in Canada by a mega-corporation which no longer cares about tradition, but about the inevitable almighty dollar. |

A1)
31... Kxh3

You have reversed colors:
Your mean:
31...h3+
A1)
32.Kxh3 Ne3+
33.Kh4 Ng2+
34 Kg5 Qf5+?? (this loses to 35.Qxf5, but sure you mean 34...Qd5+; then 35.Be5 Qxe5+ 36.Kg4 Qh5+ 37.Kg3 Qg5+ 38.Kh3 Nf4#; or 35.Be5 Rxe5+ 36.Kg4 Rg5+ 37.Kh3 Qe6+ 38.Qf5 Qxf5#) |

| Mar-01-13 | | abuzic: <Kiril Simeonovski: This is an easy one, but after 31... h3+ 32. Kg1 Qe1+ 33. Qf1, Black cans also play 33... Qd2.>
This loses to 34.Qc4+ and now black will be mated.
33...Nxg3 is the direct kill here, other alternative is 33...d3, 33...Kg8, 33...g5 and maybe 33...Re2. |
|
| Mar-01-13 | | fokers13: Does a Qa2-c2-d2 plan win also?
If so 5/5,saw Qe1 and Nxg3 ideas but couldn't quite piece it together. |
|
| Mar-01-13 | | fokers13: Seems like white has the immediate Qf1 but still Qd2 seems strong since if Qxh3?? Re1+ Kg2 Ne3#. Interesting stuff. |
|
| Mar-01-13 | | Kiril Simeonovski: <abuzic: This loses to 34.Qc4+ and now black will be mated. 33...Nxg3 is the direct kill here, other alternative is 33...d3, 33...Kg8, 33...g5 and maybe 33...Re2.> After 34. Qc4+, Black simply avoids any threats by sheltering his King in the corner with 34... Kh8. Note that White cannot take the pawn on d4 since Black Queen on d2 defends the pawn. |

The correct one is 31... h3+ 32. Kg1 Qe1+ 33. Qf1 Nxg3 34. fxg3 and now 34... Qd2 instead of 34... Qe3+. |
|
| Mar-01-13 | | David2009: T Nyback vs M Matthiesen, 2003 Black 31...? 31...h3+ looks good: (A) 32.Kf1? Qe1#; (B) 32.Kg1 Qe1+ 32.Qf1 d3 33.Bf4 Nd4 threatening Ne2+ etc; (C) 32.Kxh3 Ne3+ 33.Kh4 Ng2+ 34.Kb5 Qd5+ 35.Kxg6 Re6#. If Kh6 Qh5# and if Kf6 Re6#. Time to
check:
====
I missed the best continuation after 31...h3+ 32.Kg1 Qe1+ 32.Qf1 namely 32...Nxg3!. 32...d3 also wins but more slowly. Here's the puzzle position colours reversed

| Mar-01-13 | | abuzic: <fokers13: Does a Qa2-c2-d2 plan win also? > Indeed, after 31...h3+ 32.Kg1 Qa2 wins, for example: 33.Qd1 Qc2 34.Qf1 d3 35.Rc7 Qd2 36.Rc1 Qe2 this is winning for black but has spoiled the momentum of the mating attack |
|
| Mar-01-13 | | James D Flynn: White is 2 pawns up and has a R on the 7th rank, however, his back rank looks vulnerable and Black can force his K to retreat there by 31……h3+ 32.Kg1(if Kxh3 Ne3+ 33.Kh4 Ng2+ 34.Kg5 Qd5+ 35.Kxg6(if Kh6 Qh5#) Re6#) Qe1+ 36.Qf1 d3(not Qxb4 37.Qxh3 Re1+ 38.Kg2 Ng7 39.Ra8+ Kf2 40.Qd7+ Kf6 41.Ra6+ Kg5 42.Qg4+ Kh6 43.Qxg6#) 37.Rd7 d2(threat 38…..Qxf1+ 39.Kxf8 Re1#) 38.Rxd2 Qxd2 39.Qc4+ Kg7 40.Qc7+ Re7 41.Be5+ Kh7 and White runs out of checks , he is a R down and has answer to the back rank mate threats. |

That clarifies the idea. |

| Mar-01-13 | | patzer2: <abuzic> Thanks for the analysis of 31...h3+ 32. Kxh3 Ne3+ 33. Kh4 Ng2+ 34. Kg5 (I got that far in my calculation, but missed the next move) 35. Qd5+!  .<SuperPatzer77> Thanks for the analysis 35. Kh1 Qxf3+! 36. Kg1 Re1! (mate soon to follow) which for me really emphasizes the deflection (removing the guard) theme here in this combination. |
|
| Mar-01-13 | | abuzic: <patzer2>
I like to call this 31...h3+: a pawn on h3 is worth a ... Queen. |
|
| Mar-01-13 | | snakebyt: I started off with 31....Ne3+ and played it out to blk win. I see now that h3+ is mo betta. |

|
| Mar-01-13 | | BOSTER: <SoberKnight> <Someone please post the variations>. Puzzle can't begin with such rude move like 31...hxg3.
So 31...h3+
Here white has two possibilities to take the pawn or refute it.
If 32.Kxh3 Ne3+ 33.Kh4 Ng2+ 34.Kg5 Qd5+
all line is forced. Now if 35.Kg4 Qh5#
if 35.Kf6 Re6#
if 35.Kxg6 Re6#
if 35.Be5 Rxe5+ 36. Kg4 Rg5+ 37.Kh3 Nf4+ and then Nxd3 ,if after 36.Kh6 Rh5+ 37.Kxg6 Nf4+ 38.Kf6 Qe5#. If 32.Kg1 Qe1+ 33. Qf1 d3 now if 34.Bf4 Nd4(or Nh4) and white has no defense against Nxf3+. if 34.Rd7 d2 35.Rxd2 Qxd2 36. Qxh3 Re1+ 37.Kg2 Ne3#
if 34.Rd7 d2 35.f4 Qxf1+ 36. Kxf1 Re1#. |
