| Sep-25-10 | | gofer: What a wonderful combination!!!!
25 Qxc4+ ...
1) Try to run!
25 ... Kf8
26 dxe7+ Kxe7 (Ke8 Qg+ Kxe7 Bf6#)
27 Bxc3!!!
The king is in a mating net, not from Bc3, but from Pg5, Rd1 and Qc4, all the bishop has to do is control the
b1-g8 diagonal and black is dead. But black's queen is threatened so black has no time to play defensive moves
like Rd5! 27 ... Rxd1+ 28 Rxd1 changes nothing! The following is unavoidable without huge
material loss! 28 Bb4+ Ke8 29 Qg8#
2) Try to hide!
25 ... Qd5?
26 Rxd5 cxd5
27 Qf4! cxb2+
28 Kxb2 Rab8+
29 Ka1 Bf8
30 Rd1 and black's position is hopeless...
Main Line...
25 ... Bf7
26 Qxf7+!!! Kxf7
27 Rxh7+ ...
White has only 5 legal king moves...
27 ... Ke6 28 Rxe7#
27 ... Kg6 28 Rg7+ Kh5 29 Rh1#
27 ... Ke8 28 Rxe7+ Kf8 29 Bg7+ Kg8 30 Rh1! cxb2+ 31 Kb1 with Rh8# next move! 27 ... Kg8 28 Rg7+ Kf8 (Kh8 Rh1#) 29 dxe7+ Ke8 30 exd8+ Rxd8 31 Rxd8+ Kxd8+ (Qxd8 Rg8+ winning) 32 Bc7+ Qxc7 33 Rxc7 cxb2+ 34 Kxb2 Kxc7 35 g6! winning 27 ... Kf8 28 dxe7+ (Ke8 transposes into the line above) Kg8 29 Rg7+ Kh8 30 Rh1# Wow! If I were black I would not have seen this coming... OMG!!! |
|
| Sep-25-10 | | WhenHarryMetSally: black's last gasp: 30.......Pxb2 and follow up with a sacrifice of the black queen, and black is down for the count, but not quite out..... |
|
| Sep-25-10 | | fritochip: There seems to be a forced win I found with 25. Rxh7, cxb2+ 26. Kb1, f4+ 27. e4 Bxh7, (black has no exhausted the available checks and no mate is left) 28. Qxc4+, Kf8 29. dxe7+ Kxe7 30 Bf6+ Ke8, 31 Qe6 ++. Can anyone find where I may have erred? Thanks,
Fritochip |

 | | OhioChessFan: A lot of forcing moves, so a fairly easy Saturday for me. Most Saturdays I am more like this: http://farm4.static.flickr.com/3058... |
|
Sep-25-10
| | OhioChessFan: <frito> in your line, 30...Kf8 and Black is still better. But before that, 27...Kxh7 and Black is easily winning. |
|
| Sep-25-10 | | whiteshark: I'm weirded out. Bloody eliminative materialism. |
|
| Sep-25-10 | | timothee3331: My candidates are 25.Qxc4+ 25. Rxh7
I started to calculate 25.Rxh7 but reverted back to 25. Qxc4 + because it's more logical to calculate the forced moves :25.Qxc4+ Bf7 (only move ) 26.Qxf7+ (the and other candidates 26.Rxh7 and 26.g6 don't seem very convincing )
Kxf7 27.Rxh7+
I) 27...Ke8 28.Rxe7+ Kf8 29.Bg7+ Kg8 30. Rh1! cxb2+ 31. Kb1 ! Qe1+ 32.Rxe1 Rf8 (!) 33.Bxf8  II) 27...Kf8 28.dxe7+ Ke8 29.exd8/Q+ Rxd8 30.Rh8+ Kf7 31.Rhxd8 Qxe5 (or 31....cxb2 32. Kb1! idem) 32.R1d7+ Kg6 33.Rg8+ Kh5 34.Rh7 mate! III) 27...Kg8 28.Rg8+ and we go back to the same variations. |

 | | scormus: Yesterday I gave myself a pat on the back for finding the winning game continuation, only to learn that it was a blunder. I try to do better today Lots of threats and counterthreats but I'm inclined to the "when in doubt take with +" 25 Qxc4+. Then 25 ... Bf7 (25 ... Kf8 26 dxe7+ Kxe7 27 Bf6+). 26 Qh4 looks promising but seems to come up short. The move I really love is 26 Rxh7 if 26 ... Kxh7 27 Qxf7+ 1-0
if 26 ... cxb2+ (when in doubt take with +) 27 Bxb2 Bxc4 28 Rg7+ Kf8 29 Rh1 1-0 if 26 ... Bxc4 (B's best try?) 27 Rg7+ Kf8 28 dxe7+ Ke8 29 exd8Q+ Rxd8 30 Rh1. B cannot defend against the threat on h8 but he can set up threats of his own by 30... Rd1+ and W needs strong nerves to play 31 Kxd1. B can get some +s but the WK can find shelter on f2 I must admit, that final line took some finding and I'm still not sure I havent missed something. I sure wouldn't want this position in time pressure. Now to check. |

| | scormus: Oh, 26 Qxf7 instead. A clearer win than mine. Strange, when I looked at that earlier I thought I saw an escape for B, but I was mistaken. Oh well, nearly got it. |
|
| Sep-25-10 | | Fenario: I was thinking
25. Rxh7 Bxh7
26. Qxc4+ Kf8
27. Qe6
No doubt there's a flaw somewhere. |
|
| Sep-25-10 | | El Trueno: White to play 25. ?
The solution would be 25.Qxc4+ Bf7 26.g6!
Bxg6 is not allowed and if 26...hxg6 then 27.Rh8#
26...Bxc4 27.Rxh7! and the next move will be 28.Rh8#
If black plays cxb2+ then white answers Kb1. This is just my opinion. I am not sure but after 25.Qxc4+ Bf7 26.Qxf7+! Kxf7 27.Rh7+ would work also very well Time to check |
|
| Sep-25-10 | | El Trueno: Well my second line was right. But I do not see anything wrong in my first line, so would it also work ? |
|
| Sep-25-10 | | EXIDE: Very nice ending. All pieces fall together for white including pawns. I did not see the Queen sacrifice on move 26, so i missed this puzzle. |
|
| Sep-25-10 | | BOSTER: 25.Qxc4+ begins nice combo,but move 24... Qd5 spoils it's brilliance.
Nevertheless white will win. |
|
Sep-25-10
 | | Jimfromprovidence: I tried to get too cute and it cost me. I went with 28 dxe7, thought it was an easy win, but it sets up a forced mate for black instead!

 | | moronovich: <El Trueno> I prefer your line to the
game !
p.s.:I had the same.;) |
|
| Sep-25-10 | | wals: Too classy for me, but I do appreciate the crispness and style in which it was executed. Black: major error: depth 19: time 6 min:
(+9.24):24...bxc3.
Best,
1.  (0.37): 24...Bxd6 25.Bxd6 bxc3[] 26.Qxc4+ Bf7[] 27.Qxc3[] Qxc3+ 28.bxc3 Bxa2 29.Rh6 Bf7 30.Rd4 a5 31.Be5 Re8 32.f4 c5 33.Ra4 Bb3 34.Ra1 Re6 35.Rxe6 Bxe6 36.Bd6 c4 37.Ra4 Kg7 38.Bc7 Bd7 39.Rxa5 2.  (1.11): 24...Bxg5 25.f4 bxc3 26.Qxc4+[] Bf7 27.Qxc3[] Qxc3+ 28.bxc3 Bg6 29.fxg5 Kf7 30.Bf4 Ke6 31.Kc2 Rab8 32.Rh2 Rb6 33.c4 Rd7 34.Kc3 Rdb7 35.Rdd2 Ra6 36.Rb2 Rab6 37.Rbf2 Kd7 38.Kd4 Rb8 This was the end for Black who resigned at move 30 with a Queen for a Bishop and two pawns.
If played out the game may have progressed:-
1. (#9): 30...cxb2+ 31.Bxb2[] Qe1+ 32.Rxe1[] Rab8 33.Bc3 Rb1+ 34.Kxb1[] Rb8+ 35.Kc2 Re8 36.Rxe8+ Kf7 37.Re7+ Kf8 38.Rh1 c5 39.Rh8# 2. (#1): 30...Rxd6 31.Rh8#[]
3. (#1): 30...Qxa2 31.Rh8#[]
4. (#1): 30...a6 31.Rh8#
5. (#1): 30...Re8 31.Rh8#[] |

25. Rxh7 Bxh7
26. Qxc4+ Kf8
27. Qe6
No doubt there's a flaw somewhere.>
At the 25th move, both Kings are exposed. Neither side has the time to make a move that isn't a check. So even though 25. Rxh7 is strong, it's not a check, and Black can counterattack starting with 25...cxb2+ White never gets a chance to catch his breath. Meanwhile, the h7 Rook is hanging. |

|
| Sep-25-10 | | Fenario: Thanks OhioChessFan. I see it now. |
|
| Sep-25-10 | | butilikefur: <25. Qxc4+ Kf8> 25...Bf7 26. Qxf7+ Kxf7 27. Rxh7+ Kg8 (27...Ke8 28. Rxe7+ Kf8 29. Bg7+ Kg8 30. Rh1 wins) 28. Rg7+ Kf8 29. dxe7+ Ke8 30. Rxd8+ Rxd8 31. exd8=Q+ Kxd8 32. Bc7+ Qxc7 33. Rxc7 Kxc7 34. g6 <26. dxe7+ Kxe7 27. Bf6+ Kf8 28. Rxd8+ Rxd8 29. Bxd8> looks won |
|
| Sep-25-10 | | rapidcitychess: Whew. That's a puzzle. |
|
| Sep-25-10 | | James Bowman: Totally missed it, saw the Qxc4check but thought surely that Rxh7 first removed the bishop and opened the queen to do her deed somehow, very nice puzzle. |
|
| Sep-26-10 | | M.Hassan: "Very Difficult"- White to play 25.?
White is a Bishop down.
Unusual to have 3 pawns on one file as Black has it and White Q is pinned and the best move to get it out of pin is:
25.Qxc4+ Bf7
White Bishop on diagonal, pawns on d6 and g5 plus almost open h file may justify Queen sac. hence;
26.Qxf7+ Kxf7
27.Rxh7+ Kf8(best spot IMO)
28.dxe7+ Ke8
29.exd8=Q+ Rxd8
30.Rxd8+ Kxd8
31.Bc7+ Qxc7
32.Rxc7 Kxc7
And g pawn will be promoted 1-0
Time to check
-------------
more or less, the same trend. I am a Saturday survivor! |
