| Aug-14-11 | | TheBish: Small correction: I forgot that the Black pawn is on f5, so in analysis above, it is mate after 21...Qh4 22. Rxh4#. Not that it matters much! |
|
Aug-14-11
 | | FSR: I know the solution, but I don't think it's "insane" in any case. 14.Qh4 f5 15.Qh7+ Kf7 16.Qxg6+! Kxg6 (16...Kg8 17.Qh7+ Kf7 18.Bh5#) 17.Bh5+ Kh7 18.Bf7+ Bh6 19.g6+! Kg7 (19...Kh8 20.Rxh6+ Kg7 21.Rh7#) 20.Bh6+ Kh8 and now either (a) 21.Bxf8+ Qh4 22.Rxh4# or
(b) 21.Bg5+ Kg7 22.Rh7#. |
|
| Aug-14-11 | | patzer2: For today's Sunday solution, 14. Qh4!! uses the open file as a key part of a decisive attack on Black's weakened castled position, completing an instructive game against the Pirc defense. |
|
| Aug-14-11 | | M.Hassan: "Insane" White to play 14.?
Sides are equal and each has lost two pawns.
The clear h file shouts to put the Queen on h4 threatening mate on h714.Qh4 f5 (to make room for King to escape)
15.Qh7+ Kf7
16.Qxg6+! Kxg6
17.Bh5+ Kh7
18.Bf7#
On move 16, Black could decline taking the Queen. The game continues and Black further weakens:
16.Qxg6+ Kg8
17.Qxe6+ Rf7
18.g6 NC7
19.gxf7+ Kf8
20.Nxc7 Qxc7
And White is way ahead in exchanges by a Rook+Bishop+a pawn
Time to check
------------
In my original analysis, Black is not checkmate on move 18.I missed that Bishop was there to defend.
Still not bad for a Sunday |
|
| Aug-14-11 | | sevenseaman: How'd Black defend against a Q check on h7? 14...f5 is the only
plausible resource(permits K to go to f7), even if with some dire
limitations.
<14. Qh4 f5▢ (e.p. capture is no good) 15. Qh7+ Kf7▢> 
click for larger viewNow White has a choice of keeping the Black K engaged in deadly combat
with the sac of his Q on g7 or g6. The latter is promising on a/c of
White's handily placed LSB. So;
<16. Qxg6 Kxg6▢ 17. Bh6+ Kh7▢ 18. Bf7+ Bh6▢
19. g6+! Kg7▢ 20. Bh6+> should lead to resignation here.

This Sunday has produced a very fine puzzle but despite the 'insane' tag
I have found it logically flowing, as will most others. |

| Aug-14-11 | | sevenseaman: The following puzzle that I had solved just before tackling the Sunday
POTD, has a similar theme and the idea was of fresh help in working on
the POTD.

| Aug-14-11 | | Once: A beautiful finish. It's mostly forced, but there are a couple of little sidelines to enjoy. After 16. Qxg6+ Kg8
click for larger viewwe could grab lots of material with 17. Qxe6+ Rf7 18. g6. But <FSR's> line is crisper: 17, Qh7+ Kf7 
click for larger viewAnd now either 18. g6 or 18. Bh5 are both mate in one. The black knight does a fantastic job in guarding the black squares to seal off the black king's escape route. In the game's final position, after the forced 20...Kh8 we have a choice of three different mates in two. There is the "Reservoir Dogs" materialistic bloodbath with 21. Bxf8+ Qh4 22. Rxh4#. Or there is the nobody-gets-hurt "A-Team" ending with 21. Bg5 Kg7 22. Rh7#. But my personal favourite has to be the slow-motion ballet-like athleticism and noble sacrifice of the "hidden tiger, sleeping dragon" mate: 21. Bg7+ Kxg7 22. Rh7# 
click for larger viewNow isn't that a pretty picture? |
|
| Aug-14-11 | | Once: <sevenseaman> Enjoyed your side puzzle. 1. Qxh7+ Kxh7 2. Rh3+ Kg7 3. Bh6+ K any 4. Bf8# And the final bishop move has to be to f8 to deny the black king the g7 escape square. Enjoyable stuff. And when the Mem asks what I am doing I shall say "I'm loading the pattern recognition buffer". |
|
| Aug-14-11 | | rhickma4: The first move looks obvious
14.Qh2
Now Black needs to clear f7 to avoid mate: both 14...f6 and 14...f5 look to lead to the same line.
14...f5 15.Qh7+ Hf7 16.Qxg6+ Kxg6 17.Bh5+ Kh7 18.Bf7+ Bh6 19.g6+Black has 2 choices here:
19...Kg7 20.Bxh6+ Kh8 21.Bxf8+ and wins, or
19...Kh8 20.Rh6+ and 21.Rh7#
The are a few places where Black can give a material to delay things, but thats all.
Looks straightforward for Sunday once you see 16.Qxg6+ |

Aug-14-11
 | | LIFE Master AJ: I think I have seen this one somewhere once before ... I think it starts out 14.Qh4, f5▢; 15.Qh7+, Kf7▢; (The only legal move, I think.) 16.QxP/g6+!! I don't rememebr how it goes after that, but it looks like Black's King is in a box after 16...KxQ/g6; 17.Bh5+, etc. In case someone (mistakenly) thinks that I considered this easy, it is now exactly 03:25 AM on my computer. (Phooey on you, M.F.!!!) I think I have (now) spent close to an hour on this one, I am also nodding a bit in front of the computer. |
|
| Aug-14-11 | | morfishine: This game looks like it belongs in Chernev's "1000 Best Short Games of Chess". Of course the original copyright of that book was 1955 while this game was played 23 years later. |
|
| Aug-14-11 | | UnsoundHero: White's position is so strong that he can go straight into 14 Nf6+, so that Black can never move his Pf7. If 14...Bxf6 15 Qh4 leads to mate. Or 14...Nxf6 15 gxf6 Bxf6 16 Qh2 Bh4 17 Qxh4 winning a piece. But, of course, the spectacular mating attack looks stronger. Still, how could Donner play so weak? |
|
| Aug-14-11 | | newzild: I managed to get this. The toughest move for me was 19. g6+. For some time I could see nothing better than 19. Rxh6+?, as my visualisation of the board six moves in was getting a little dim. |

| | LIFE Master AJ: You could say that Donner showed deep and explicit (suicidal) feelings in managing his chessical emotions. Haha, I don't know which is worse ... my joke or Donner's defense here! |
|
| Aug-14-11 | | Willem Wallekers: Donner: "Now I'm the Chinese Kieseritzky" |
|
| Aug-14-11 | | ProjectR: The only reason i solved this,although it took me 10 minutes is because i know its a puzzle,i would never have seen this combination over the board.
An excellent game |

Sherlock Holmes:- Because you are not wearing any trousers either. <LMAJ> Where was 'the joke'? |
|
| Aug-14-11 | | standardwisdom: Sweet sixteen! What a beautiful move.
Qh4 and Qh7 are plain as a pie, but sixteenth move is splendid. |
|
| Aug-14-11 | | gofer: OMG! A forced mate in 9 with a queen sacrifice thrown in
for good measure!!! The <CG> gods are smiling on us today! 14 Qh5 f6/f5
15 Qh7+ Kf7
16 Qxg6+!! Kxg6
17 Bh5+ Kh7
18 Bf7+ Bh6
19 g6+! Kg7
20 Bh6+ Kh8
21 Bxf8+ Qh4
22 Rxh4#
Okay this may not be the way it went down, but it "sure is pirtty!" and it
seems difficult for black to avoid as I think it looks like a forced
combination.
Time to check... |
|
| Aug-14-11 | | Creg: After looking things over, I see 14.Qh4 threatening 15.Qh7mate. The only real defense is 14...f5, or f6. 14.Qh4 f5 15.Qh7+ Kf7 16.Bh5, this seems like a key move. White must continue the attack else 16...Rh8 follows. But now things get tricky. 16...Ne7 how does white continue?
17.Nxe7 Kxe7 18.Qxg6, I'm not so sure that's correct. Wait, what about
17.Bxg6+ Nxg6 18.Rh6
I can't see it all, so I'm going to see how this went down --------
A beautiful queen sacrifice, and I missed it...Doh! |
|
| Aug-14-11 | | whiteshark: Is it just me or was JH Donner really the approved point supplier for Commies during 60ties/70ties? |
|
| Aug-14-11 | | Marmot PFL: maybe black's last chance to survive was 12...Nc7. It looks ugly but he needs to get rid of Nd5, which he should never have allowed there to begin with. |
|
| Aug-14-11 | | agb2002: This is the first game in Liu Wenzhe's "The Chinese School of Chess" and, if I remember correctly, it was the first time that a Chinese player beat a western grandmaster. The position before the queen sac has been given many times as a combination exercise. Therefore, not a puzzle but chess culture. |
|
| Aug-14-11 | | agb2002: I was not aware of Liu Wenzhe vs Krogius, 1965. An interesting game. |
|
| Aug-14-11 | | David2009: Liu Wenzhe vs J H Donner, 1978 White 14? Insane
The immediate 14.Qh2 is met by 14...f5 or 14...f6. But if 14.Nf6+ Nxf6 15.gxf6 Black is fine.
So we'll play 14.Qh2 after all expecting 14...f5 15.Qh7+ Kf7. Now 16.Qxg6+!? may or may not work (the idea is 16...Kxg6 17.Bh5+ which may or may not work),
but the point is I do not have to decide this from the original diagram. Time to
check:

THe EGT gives away all its pieces to confuse you, but be careful. In the main variation it postpones mate for 19 moves. Enjoy searching for a faster mate! |
