| Oct-23-12 | | diagonalley: this as easy as a monday puzzle! |
|
Oct-23-12
 | | Phony Benoni: Naturally tried 28...Rxf1+ 29.Kxf1 Qd1+ first, but the rook just interposes. Then noticed the position of the queens, and realized finding a way to move the bishop with check was the key. Pretty straightforward today, once you notice that detail. |
|
| Oct-23-12 | | stacase: Took just a few seconds to see it, made me chuckle. 28 ...Rxf1+ forcing 29 Kxf1 and then 29...Bxf2+ leaving Black's unprotected Queen exposed and naked while her King has to run for his life. |
|
| Oct-23-12 | | Patriot: Well the white queen is undefended and I see that 28...Rxf1+ 29.Kxf1 Bxg2+ 30.Kxg2 Qxb6 is winning, so that's what I'm going with. |
|
| Oct-23-12 | | Abdel Irada: <The perils of blitzin' Donner<<<>>>> Apparently White got carried away with his attack and failed to notice his undefended queen. As a result, Christmas comes early for Black: <28. ...Rxf1†!
29. Kxf1, Bxg2†
30. Kxg2, Qxb6<>> And when the paperweight snowstorm settles, Black has won a queen and a pawn for a rook. Joyeux noel! |
|
| Oct-23-12 | | lost in space: 28...Rxf1+ 29. Kxf1 Bxg2+ 30. Kxg2 Qxb6 and White is down a rook. Time to resign |
|
| Oct-23-12 | | Abdel Irada: Looking at the game, it seems White's mistake was a premature/overoptimistic 26. Bxa6. Black's tactic would never have existed had he instead played 26. a5. It's not hard to see, however, after the course of the game up to that point, why White would feel sanguine and fail to look ahead far enough to see that Black gains a critical tempo by attacking the rook with 27. ...Qd6, which also prepared the winning combination. |
|
| Oct-23-12 | | Gregor Samsa Mendel: Could white have avoided immediate material loss by playing 28 Qe3? |

 | | perfidious: <GSM> Black has a lot of play for the pawn after your idea with such possibilities as 28....Qa3 or 28.... Rd8, but hard to tell whether it is enough without more analysis. In a practical game, I'd prefer Black. |
|
| Oct-23-12 | | Patriot: <<Gregor Samsa Mendel>: Could white have avoided immediate material loss by playing 28 Qe3?> That's a good question. The one move that concerned me was 28...Bd5 with 29...f6 to follow. 28.Qc5 looks safer I think. |
|
| Oct-23-12 | | xthred: Yay! Got one. |

 | | FSR: 28..Rxf1+ 29.Kxf1 Bxg2+ wins the queen. |
|
| Oct-23-12 | | Caissas Clown: I was looking for all sorts of fancy moves , none of which did the trick.
It was only when I saw this marked "easy" that I spotted Rxd1 at once.
Wouldn't it be nice to have CG's classification of a position with a forced win , pop up in front of you OTB? |
|
| Oct-23-12 | | bachbeet: Got it though I must say that the advantage of the Q and R vs 2 Rs is not overwhelming. |
|
| Oct-23-12 | | Moonwalker: The piece arrangement suggests the key is 28...Rxf1+ 29.Kxf1 (forced) Qd1+ but then 30.Re1 ruins everything. Noticing the undefended white queen, however, confirms the key but the continuation should be 29...Bxg2+ 30.Kxg2 Qxb6 
If there's a mate there somewhere I haven't found it.ENDS
Cool bananas! |
|
| Oct-23-12 | | stst: It's the Q, not the K, that matters!!
28...... RxB+
29.KxR BxP+
30.K-any QxQ
Losing the Q, W won't last long... |

| Oct-23-12 | | Tired Tim: <Abdel Irada> - Thank you for the attractive word play I wondered if Berg had made a titanic mistake, but decided not to go there |
|
| Oct-23-12 | | newzild: This reminds me of a position from one of my earliest games. Bill Ramsay - newzild, 1996

| Oct-23-12 | | morfishine: Donner "Ices Berg" with <28...Rxf1+ 29.Kxf1 Bxg2+ 30.Kxg2 Qxb6> and the White Queen is lost Sadly, I don't see any colorful variations to have fun with today. |
|
| Oct-23-12 | | Swedish Logician: It is nice to see Donner beating Van den Berg for a change. Donner lost two famous and almost identical Scicilian Najdorf games to Van den Berg:
C B Van den Berg vs J H Donner, 1965 and another one in 14 moves a decade earlier. Here Rxf1+ and Bxg2+ should do the trick, though. |
|
| Oct-23-12 | | captainandrewwiggins: i couldn't see this one after a perfunctory glance. i'm disappointed with myself. |
|
| Oct-23-12 | | whiteshark: 28...Rxf1+
29...Bxg2+
30...Qxb6
and that's it. |
|
| Oct-23-12 | | Once: <Abdel Irada: Looking at the game, it seems White's mistake was a premature/overoptimistic 26. Bxa6.> I don't see it quite the same way. Here's the position after 26. Bxa6 Qd6 
click for larger viewIn the game, white doesn't spot the real reason for 26...Qd6 and plays 27. Rge3? And we have all seen what happens after that. But instead, can't white simply retreat his queen to a square where it defends the rook? I see three candidates - Qa5, Qe3 and Qc5. Then consolidate, protect the rooks, close the e file with an eventual Re3, swap pieces and win the endgame. Fritzie reckons that 27. Qa5 is worth +0.9 - ie white keeps the advantage of the pawn he won with 26. Bxa6. Tne move I wanted to play in human mode was 27. Qe3, which Fritz says leads to a level(ish) position, as does 27. Qc5 I think what lost the game here was that white didn't spot black's tactic. 28. Rge3 is the culprit and not 26. Bxa6 |
|
| Oct-23-12 | | Oxspawn: I don’t see a mate, but I do see a winning combination. <28. Rxf1+
29. Kf1 Bxg2+
30.Kxg2 (or Ke1/e2) Qxb6>
Blacks gains queen, bishop and pawn for rook and bishop – although I cannot see any quick mating attack. |
|
| Oct-23-12 | | francis2012: A simple ♕ trap. ♖xf1+ ♔xf1 (a force move), ♗xg2+ (a discovery) after White takes the Black's ♗ Black simply replies with ♕xb6. |
