| Jul-16-07 | | THE pawn: Ouch, very powerful attack by Ernst here. He scored pretty well too, during the open. |

 | | Phony Benoni: The pattern of ...Rxf2 followed by ...Qh2+ is a common tactical idea. It took a minute to see the follow-up would be more queen checks, eventually nudging the king to a dark square. 23.Kf3 Qh3+ 24.Ke2 Qg2+ is one of the crucial lines.
I don't think 23.Kf1 Qh1+ works as well; Black's queen need to cover e3 to foil the rook interposition. Nice practice in using ♕+♗ in a mating attack. |
|
| Sep-05-12 | | ParisianRedneck: Whatd the mating line from here? ...Ke2 |

| Sep-05-12 | | LoveThatJoker: Cool! A GM Ernst puzzle!
There's a pic out there of him sporting a Tool shirt, so along with the fact that he's a GM, this dude gets my props for his taste in music! <21...Rxf2+ 22. Kxf2> (22. else Qh2#)
<22...Qh2+> and Black wins. For example,
A) 23. Kf3 Qh3+ 24. Kf2 (24. Ke2 Qg2+ 25. Ke3 Bd4#) 24...Bd4+ 25. Re3 (25. Ke2 Qg2#) 25...Qxe3+ 26. Kf1 Qf2# B) 23. Kf1 Qh3+ 24. Kf2 (24. Kg1 Bd4+ 25. Re3 Bxe3#; 24. Ke2 Qg2+ 25. Ke3 Bd4#) 24...Bd4+ 25. Re3 (25. Ke2 Qg2#) 25...Qxe3+ 26. Kf1 Qf2# LTJ |
|
| Sep-05-12 | | Patriot: White is up the exchange for two pawns.
21...Rxf2+ 22.Kxf2 Qh2+
A) 23.Kf3 Qh3+ 24.Kf2 Bd4+  (24.Ke2 Qg2+ 25.Ke3 Bd4#) B) 23.Kf1 Qh1+ 24.Kf2 or 24.Ke2 as in A.
C) 23.Ke3 Bd4+ 24.Kf3 Qh3# |
|
| Sep-05-12 | | LoveThatJoker: Now that I can move the pieces, I see that I missed that in lines 'A' and 'B', 25...Qxe3+ is met by 26. Kg2 - something that I should not have missed really anyways. Stockfish confirms that Black is still winning, but a deduction for me for missing this in my solution post. 0.60 out of 1 today.

| | Phony Benoni: By the way, I see nobody has yet mentioned the nice mate in two if White tries 26.Ke2 in the final position.
click for larger viewOr maybe it's just obvious for everybody else. |
|
| Sep-05-12 | | dick50: It appears black has already exchanged one of his rook with a minor piece, so as start the process of disrobing White King. The other Rook should continue with the same process by removing f pawn 21...Rxf2 22 Kxf2.
Now Queen enters the fray with 22...Qh2+. This should be followed by some duel between Black Queen and White King. White king would eventually be forced to move to f2 or e3, when DSB enters the scene at d4. The end. |

| Sep-05-12 | | Djoker: 21. ...Rxf2+
22. Kxf2 (else....Qh2#)Qh2+
A> 23. Kf1 (Ke3 Bd4+ 24.Kf3 Qf2#)( Qh3+
24. Kf2(Ke2..Qg2+ 25.Ke3 d4#) Bd4+
25. Re3 Bxe3#
B> 23. Kf3 Qh3+ 24. Kf2 (Ke2 is same line as above) Bd4 25. Re3 Qxe3 26. Kg2 Qf2+ 27.Kh1 ....I am missing a mate threat if its there, though black has advantage..I guess this is the best defense for white.
An interesting line in B would be 25...Bxe3 26. Ke2 (Ke1 is mate in 2)..Qxg4+ 27. Nf3 (Kxe3...Qxd1)(any other move is mate in two) Qg2+ 28.Kxe3(avoiding mate) Qxa2..with overwhelming advantage.In conclusion I would say White should have sac'd rook in 21st move and strengthened its king defense. If black captures rook by bishop.White Queen takes control of the diagonal. |

 | | An Englishman: Good Evening: The key to solving this one lay not in finding the first move but in figuring out how to check the White King onto a dark square so that the Bc3 can join in the fun with check. |
|
Sep-05-12
 | | FSR: After 21...Rxf2+ 22.Kxf2 Qh2+, Black's queen and bishop are mating White off the board. |
|
| Sep-05-12 | | Muztang: @Phony: the mate in two is cute indeed! I wouldn't have spot it without your comment. Instead, I was grumbling "what the hell did I miss..." Thanks! |
|
Sep-05-12
 | | al wazir: I got the ♖ sac and saw the attack with the ♗ and ♕, but I wanted to play 23...Bd4+. That fails after 24. Kf1 because black has no good checks. (24...Qg3/Qh2 is answered by 25. Qf3.) It's important not just to make the right moves, but to make them in the right order. |
|
| Sep-05-12 | | rilkefan: This was a difficult Wednesday for me - I started down the right path immediately but it took probably a few minutes to realize that ...d4/...Bc6 (or anything else) wasn't the way to go and that 24...Bd4+ could be arranged. Thanks to <PB> for prompting me to realize that my planned ...Qg4+ at the end picking up the queen is just losing the thread - esp. when I had before considered that the white king was running out of liberties (to steal a go term) because of the pawns. |
|
| Sep-05-12 | | sevenseaman: After yesterday's snorter, I had a long look at this one. What crossed my mind first was to eliminate the N and double the pressure on 'f' file with 22. Q f4. It looked a sound approach except that the white Q momentarily abandoned the cover of f3 and also, I did not see anything 'spectacular' about it. Seeing the Black Q's reach up to h2 the idea of saccing the R on f2 came up somewhere. I soon developed this; <21...Rxf2+ 22. Kxf2▢ Qh2+> and any contortions the White K chooses now can be taken care of. I had this foray; <23. Kf1 Qh3+ 24. a) Ke2 Qg2+25. Ke3 d4#> 0-1. <24. b) Kf3 Qh3+ 25. Kf2 Bd4+ 26. Ke2▢ Qg2#> 0-1. The difficulty today is appropriate to the day of the week. |
|
| Sep-05-12 | | Abdel Irada: <The doors of inception> Having already given up one rook for bishop and two pawns, Black opens the doors of White's king position and breaks on through to the other side by saccing the other with <21. ...♖xf2†!>. White must reply with <22. ♔xf2> because otherwise he is immediately mated: 22. ♔h3?, 22. ♔g1? and 22. ♔h1? are all met by 22. ...♕h2#. Black continues 22. ...♕h2†, and White must choose one of three retreat squares: (1) 23. ♔e3?, ♗d4†
24. ♔f3 ▢, ♕f2#, or
(2) 23. ♔f3, ♕h3† and either
(2.1) 24. ♔f2, ♗d4†, when White loses with either the simple (2.1.1) 25. ♔e2?, ♕g2# or the more complex
(2.1.2) 25. ♖e3!, ♗xe3†
26. ♔e2, ♕g2†!
27. ♔xe3, d4# (or 27. ♔e1, ♕f2#).
(2.2) 24. ♔e2?, ♕g2†
25. ♔e3 ▢, ♗d4#, or
(3) 22. ♔f1, ♕h3† and again the road forks:
(3.1) 23. ♔e2, ♕g2†
24. ♔e3 ▢, ♗d4# or
(3.2) 23. ♔g1, ♗d4†
24. ♖e3 ▢, ♗xe3# or
(3.3) 23. ♔f2, ♗d4† and either
(3.3.1) 24. ♔e2?, ♕g2# or
(3.3.2) 24. ♖e3!, ♗xe3†
25. ♔e2
(25. ♔e1, ♕g3†; 26. ♔e2/♔f1, ♕f2#)
25. ...♕g2†!
26. ♔xe3, d4#
(or 26. ♔e1, ♕f2#).
So helpless is White that once the doors have opened, Black can if necessary pile his bishop on top of his rook to build a funeral pyre for the white king. |

| Sep-05-12 | | Once: This seems to be similar to yesterday's. The first two moves are fairly obvious (if you know the pattern) but the follow up needs a bit of work. The easy stuff first. From the opening position, we see that the black king is moderately exposed and the f2 square is weak. What is more, the white army isn't covering the kingside very well. So our fingers start to itch for a kingside attack. We could go the slow way, with building move like Rh8 or Qf4. The trouble with these moves is that they give white time to bring up defenders. We really don't want to give white the time to play Rh1 or Qf3 or Re3. What we need is an entry square so that we can parachute the black queen directly into the white kingside. And that's when you spot 21...Rxf2+ 22. Kxf2 Qh2+ 
click for larger viewI must admit that when I was solving this in human mode, I was a little unsure about this position. Black has only two pieces in the attack - the queen and the bishop which will eventually jump into d4. The other two black pieces are hatching conspiracies with the black king a long way from the front line. The worry is that all black has is a perpetual check - or worse that white will find a way to squeeze one his pieces into the defence or squirrel his king onto a square where it can't be easily checked, such as g3. For example, there's this line: 23. Kf1 Qh1+ 24. Kf2 Bd4+ 25. Kg3 
click for larger viewAnd on the face of it, black can't land another devestating check. Black can win from this position, but it took Fritz to find it: 25...Be5+! and now 25.Rxe5 Qxd8 or 25. Kf2 Qf2+ 26. Kf1+ Qh3+ and we are back into the proper way to win with Qh3+ instead of Qh1+ Rewind. Unless you see Fritz's 25...Be5+, it seems that 23...Qh1+ isn't the way to go. Instead, 23...Qh3+ is the move 
click for larger view23...Qh3+ does everything that 23...Qh1+ does plus it covers the crucial g3 square. White really doesn't want to run to 24. Ke2 and allow 24...Qg2+, so he has to play 24. Kf2 Bd4+ followed by a despairing rook interposition. <phony> has found one last cute trick in the position. After 26. Ke2 Qg2+ 27. Kxe3 d4# 
click for larger viewAs with yesterday, this one is quite a tough puzzle. Black was material down throughout, so he really needed to see it through to mate. And if we take the line that seems to put up the most resistance, the combination starts with 21...Rxf2+ and ends with 27...d4# And this is a wednesday? I predict much scratching of heads in CG land today. |

| Sep-05-12 | | xthred: I saw the start but I couldn't see the finish. |
|
| Sep-05-12 | | Abulherar: The Rook sac (21...Rxf2+!)looks good to me,I think that the solution is:
21...Rxf2+! 22.Kxf2 Qh2+!
A:23.Ke3 Bd4+ 24.Kf3 Qf2#
B:23.Kf3 Qh3+ 24.Ke2 Qg2+ 25.Ke3 Bd4+#
C:23.Kf1 Qh3+ 24.Kf2 Bd4+ 25.Re3 Bxe3+
26.Ke2 Qxg4+ 27.Nf3 Qg2+ 28.Kxe3 Qxa2 (Black has better position) |
|
| Sep-05-12 | | poszvald: Rxf2+ does the trick, as white will loose either queen or be mated. |
|
| Sep-05-12 | | morfishine: The final attack is actually two combinations. The first part <21...Rxf2+ 22.Kxf2 Qh2+> leaves the White King exposed plus no pieces can immediately come to his defense.
click for larger viewAt first, the second part was harder for me to visualize. However, two characteristics of this position became evident, which prove decisive: (1) The Black Queen can check freely and eventually force the White King onto a dark square, at which point <Bd4+> is fatal & (2) The Black pawns on <d5> & <g5> control <e4> & <f4> sealing off any escape in that direction. For the final sequence, I give <23.Kf3 Qh3+ 24.Ke2 (If 24.Kf2 Bd4+)...Qg2+
25.Ke3 Bd4#>
I didn't consider <23.Kf1>. I felt White's only hope was 23.Kf3 Qh3+ 24.Ke2 and if now <24...Qxg4+> White has <25.Nf3> and although his position is horrible, he dodges immediate mate. Of course, Black ignores the capture of the g-pawn with <24...Qg2+> and the White King is forced onto a dark square <e3>. |
|
| Sep-05-12 | | kasputine: For instance, it's a "she". Sipke Ernst is a woman, FIDE rating: 2548, quite strong. |
|
| Sep-05-12 | | Abdel Irada: <Once>: I disagree with your assessment. Today's puzzle is far different from yesterday's, and far simpler. The distinction between them is that there are fairly forthright forced mates in all lines of this puzzle, whereas in yesterday's we often had to settle for a clear but not immediately winning advantage. I believe this was a suitable Wednesday puzzle. As for that "Tuesday" puzzle, though, I think it should have been presented on Friday or Saturday. |
