 | | sleepyirv: F-pawn is pinned, which means Queen sacrifice, rook check, rook check on the H file, and then rook check on G file with White's king dead. |
 |
| Jan-17-11 | | wladimirsky: 16...Qxg3!
Took me more than 30 seconds. Nice to see a Monday which requires looking more than 2 moves ahead. |
|
Jan-17-11
 | | lost in space: 16...Qxg3+ 17. hxg3 Rxg3+ 18. Kh2(h1) Rh3+ 19. Kg1(g2) Rg1+ 20. Qg4 Rxg4# I love Mondays! |
|
| Jan-17-11 | | VincentL: "Very Easy".
Material equal, but black has all his major pieces bearing down on white`s king. 16.....Qxg3+ leads to mate.
(a) 17. Kh1 Qg2 mate
(b) 17. hxg3 Rxg3+ 18. Kh1/Kh2 Rh3+ 19. Kg1/Kg2 Rg8+, and mate follows after white gives up his B and Q. I have seen easier Monday puzzles.
Letīs check. |
|
| Jan-17-11 | | newzild: Yes, a mate-in-five Monday that is a little trickier than usual. |

 | | Phony Benoni: Is this as trivial as we think? What if, after <18...Rh3+>, White tries 19.Kh2 Rg8+ 20.Qg4?
click for larger viewNow 20...Rxg4+ allows 21.Kxh3 and 20...hxg4 closes down the attack, so it seems like Black must play 20...Bxg4. Now White can play 21.Rg1 with a flight square for his king. It's probably still lost, but it isn't mate. |

 | | dzechiel: Black to move (16...?). White is up a pawn. "Very Easy." This one is "very easy" in the sense that all of white's moves are forced, but it's still a six move checkmate. Starting with the obligatory queen sacrifice:
16...Qxg3+ 17 hxg3
Of course the f-pawn is pinned by the black bishop on c5, and moving the king does no good as after 17 Kh1 Qg2# is mate. 17...Rxg3+ 18 Kh2
Or 18 Kh1, it comes out the same.
18...Rh3+ 19 Kg2
Or 19 Kg1, once again it does not matter.
19...Rg8+ 20 Bg5 Rxg5+ 21 Qg4 Rxg4#
The most advanced Monday position I remember. Time to check and see when white actually resigned. |
|
Jan-17-11
| | dzechiel: <Phony Benoni> is quite right! After Qg4 black cannot take with the rook as that blocks the bishop's protection of the other rook. I really should have noticed this! |
|
| Jan-17-11 | | VincentL: <Phony Benoni>Good catch. I didn't notice this, and particularly as itīs Monday, I think many will overlook it. |
|
| Jan-17-11 | | mrsaturdaypants: Not quite so simple, is it?
16...Qxg3+ 17 hxg3 Rxg3+ 18 Kh2 Rh3+ 19 Kg2 Rg8+ 20 Qg4 And now 20...Rxg4+ leads to Kxh3. The position is still quite bad for white, but not completely losing, I don't think. If instead 20...Bxg4, I guess 21 Rg1 is best. Material is almost even, though white's pieces are barely developed. I think chessgames is messing with us. Monday indeed. Time to see what everyone else thinks. |

Jan-17-11
 | | estrick: After 20 ...Bxg4 21. Rg1,
How about 21 ...Rxc3 22. bxc3 Be2+
and after the king is forced to the h file, more bishop checks, grab the rook, and the White king is still in jeopardy? |
|
| Jan-17-11 | | mrsaturdaypants: Ah, I second Phony Benoni, who looks like Beaker. Good company indeed. This is going to be a very challenging week, I'll wager. |
|
| Jan-17-11 | | ruzon: But Black gets the rook back, right?
16...Qxg3+ 17. hxg3 Rxg3+ 18. Kh2 Rh3+ 19. Kg2 Rg8+ 20. <Qg4> Rxg4+ 21. Kxh3 <Rg1+> 22. Kh2 Rxf1. |

 | | An Englishman: Good Evening: I finally solved it, but this is the hardest Monday I've ever seen--all that trouble just to win a pawn? No mate in two? |
|
Jan-17-11
| | Phony Benoni: <ruzon> Yes, Black can get the rook back easily. And there's no denying he has a superior, probably winning position, with a strong attack and a pawn up. The point is that the <20.Qg4> defense at least stops the mate for the moment, with a more-or-less playable game. And, besides, it's such a neat move! |
|
| Jan-17-11 | | ounos: Ah, Morphy would be pleased with this game... |
|
| Jan-17-11 | | Superfish: In the variation 19. Kg2 Rg8+ 20. Qg4 Bxg4 21.Rg1 I think Black continues his winning attack with 21... Rf3! i.e. 22. Ne4 Rxf2+ 23. NxR Be2+ 24. Kh2 Bd6+ 25. Kh3 RxR. Black is also threatening Nf5 and Nh4 or Nd4. White is toast! |

 | | M.Hassan: "Very Easy" Black to play 16.....?
Balck is a pawn down
Black has four pieces aiming or directing towards White King position.Queen,Rook an 2 Bishops. He can appropriately sac one and win:16......Qxg3+
17.hxg3 (f pawn is pinned) Rxg3+
18.Kh2 Rh3+
19.Kg2 Rg8+
White has no choice except to cover the check by his Queen 20.Qg4 Bxg4
and it is mate next move.
Not that easy for a Monday! |
|
Jan-17-11
 | | patzer2: Mate-in-six on a Monday with 16...Qxg3+! This week's line up of puzzles must really be tough. |
|
Jan-17-11
| | M.Hassan: <and it is mate next move>
I noticed that although White has become week in materials but he is not mate next move. He can continue thus: 21.Re1 Bf5+
22.Kf1 Rh1+
23.Ke3 Bg4+
24.f3 Bxf3+
25.Kxf3 Rxe1
and h pawn likely to reach promotion. |
|
| Jan-17-11 | | Stormbringer: Didn't get it, even the almost but not quite mate in 6, didn't see 18 .. Rh3+ |
|
| Jan-17-11 | | gmalino: It's monday,f2 is pinned, black battery on the g-file, so it looks like the typical queen-sac: 16........Qxg3+
17.hxg3 Rxg3+
18.Kh2 Rh3+
19.Kg2 Rg8#
O.k. we know that Queens sacs are usual monday stuff, but isn't this one a little bit too complicated for mondays? We'll see soon. |
|
| Jan-17-11 | | gmalino: Yes,
19......Rg8
isn't mate, but I don't care!
Not in this line!
:-) |
|
| Jan-17-11 | | sfm: <Phony Benoni: Is this as trivial as we think? What if, after 18...Rh3+, White tries 19.Kh2 Rg8+ 20.Qg4?>
Oops. Detail. ;-)
OK, on 20.-,Bxg4 21.Rg1, maybe the fastest is 21.-,Bf3+ 22.KxR,RxR. Black threatens the killing -,Bd6 or -,Nf5 and what is White to do? 23.Kh2,Rg4 doesn't help at any affordable cost. |
|
Jan-17-11
 | | noctiferus: <dzechiel>
Actually, Kg1 and Kg2 are not equivalent: Kg1 leads to your mate, while Kg2 allows:
20.Qg4 Bxg4 21.Bxf7 Rg7 
or
20.Bg5 Rxg5+ 21.Qg4 hxg4 , worse |
