 | | Eggman: Rather weak play for a correspondence game. Oh, well - there's room for everyone in our wonderful game!
click for larger viewThe finish here is well worth memorizing. Aside from 26.Kxg2 Qg4+ 27.Kh1 Qf3+ 28.Kg1 Rg8+, there is 26.Kh1 Rxh2+! 27.Kxh2 Qh6+ 28.Kg3 Qg5+ 29.Kf3 (29.Kh3 Rg8! 30.Qd4 Qg2+ 31.Kh4 Qh2#; 29.Kh2 Qh4+ 30.Kg2 Qg4+ 31.Kh2 Rg8! and the threats on h5, h4, and g2 cannot be met) Qf5+ 30.Kg3 (30.Ke3 Rd3+ 31.Ke2 Qe4#; 30.Ke2 Qd3+ 31.Ke1 Re8+ 32.Qe5 Rxe5#) Rg8+ 32.Kh2 Qh5# |
|
| Nov-03-08 | | gtgloner: OK, it looks like 25. ... Rxg2+ 26. Kxg2 (Kh1 is fatal, of course) Qg4+ 27. Kh1 (only move) Qf3+ 28. Kg1 Rg8# |
|
| Nov-03-08 | | SuperPatzer77: <Eggman> Oh, my goodness!!! You're absolutely right about 26...Rxh2+!!. I thought it was a bad move. I've realized that it is a beautiful move - 26...Rxh2+!! I'm telling you, Eggman that 27. Kxh2 Rg8?? (blunder). Correct move is 27...Qh6+! Eggman, I still call you "Egg Genius" LOL.

| Nov-03-08 | | kevin86: A bit more complicated than the usual on Monday-especially if white plays ♔h1 on his 26th turn. It is muddy if ♕h3 or the second sac at ♖xh2 is best. |
|

| | Eggman: <<SuperPatzer77>> I'm blushing. <<kevin86>> I suppose it's a matter of taste. 26...Rxh2+ actually takes a little longer, but I always prefer the lines with the forcing checks, which I think is a good policy for the practical player. |

| Nov-03-08 | | TheaN: <newzild: <JG27Pyth: newzild: <26...Qc6! And white's toast.>
after...
27.Qb5 and I don't see any quick win for black... am I missing something?> ....Hmmm. Good point. Maybe 27...Qf3?>
Pfff how passive... 25....Rxg2† 26.Kh1 Qc6 27.Qb5 Rg1††!, as in many other variations involving a Q attacks Q by White, 28.Kxg1 Rg8† 29.Qg5 Rxg5‡. |
|
| Nov-03-08 | | TheaN: Well wouldn't you know, Fritz is very clear in saying that: <25....Rxg2†> is mate in 6, by means of <26.Kh1 Qh3 27.Qe5> and: <27....Rdg8!!> and this simple reloader threatens: <28....Rxh2†! 29.Qxh2 Qf3† 30.Qg2 Qxg2‡> or <28....Rg1†! 29.Rxg1 Qf3† 30.Rg2 Qxg2‡> and only one of these is avoidable with a defending move. If the Queen intermediates with a Queen giveaway, Qxh2‡ follows next move, and on 28.Qf5 Qxf5 with 29....Rxh2† 30.Kxh2 Qh5‡. |
|
| Nov-03-08 | | TheaN: And so it look like we all missed it... no points today! New monday puzzle tomorrow, cg! J/k. |

| | Eggman: Damn those infallible computers! But I would STILL play 26...Rxh2+ - the cascade of checks placates my very human need for security. |
|
| Nov-03-08 | | YouRang: White's g2 pawn, sitting on an open file and defended only by the king, appears to be no match for black's rook pair and queen -- especially since white's queen and rooks are ill-positioned to be of much defensive usefulness. So, 25...Rxg2+ is an obvious try, and the mate comes in to view quickly: 25.Kxg2 (or 25.Kh1 Qh3~#) Qg4+ 26.Kh1 Qf3+ 27.Kg1 Rg8# |
|
| Nov-03-08 | | AlaskaksalA: Great puzzle.
How many people here make that kind of sacrifice before seeing the full line out until the end, trusting the Gods of the King-Hunt? |

|
| Nov-03-08 | | MostlyAverageJoe: <Eggman: Damn those infallible computers! But I would STILL play 26...Rxh2+> Nothing wrong with 26.Rxh2+ (it was my brain-based choice as well). It delays the mate by 2 moves, but it seems easier to analyze. |

| Nov-03-08 | | stacase: Someone above talked about White declining the Rook sacrifice. i.e., K-h1 A Queen to h3 answer would make things pretty ugly for white |

 | | Once: It's all been said, so no point in repeating. Today, we have a half-week puzzle. The Monday bit of the puzzle is 25...Rxg2+. The Tuesday bit is realising that 26. Kh1 is a much tougher defence than 26. Kxg2. And the Wednesday part is finding one of several mates after 26. Kh1. I went for 26...Rxh2, but 26...Qh3 is much neater. Rewind to the position after 24...Rg8 and Fritz 11 reckons that either 25. Qxh7 or 25. Qc3 is 0.00. How many of us, as white, would have chosen one of those moves rather than the losing 25. Qb2? |

You wrote: " Someone above talked about White declining the Rook sacrifice. i.e., K-h1 A Queen to h3 answer would make things pretty ugly for white" Multiple people pointed this out already. |

I certainly would have chosen 25.Qc3 or 25.Qxh7, probably even in a speed game, as I think most people here would. Do you disagree, or is this what you meant to imply? |

| Nov-03-08 | | johnlspouge: Monday (Very Easy)
S Cross vs C Henderson, 1938 (25…?) Black to play and win.
Material: Down a P. The White Kg1 has 1 legal move. The Black Rd8 and Rg8 are much better developed than their White counterparts, each commanding an open or semi-open file. The Black Qe6 is also mobile. The Black pieces are so mobile, they can create a local superiority almost anywhere on the board, offering the chance of a sacrificial strike. The usual examination of checks, captures, and threats in that order reveals a candidate. Candidates (25...): Rxg2+
25...Rxg2+
White is mated if he accepts the sacrifice:
(1) 26.Kxg2 Qg4+ 27.Kh1 Qf3+ 28.Kg1 Rg1+ 29.Qg7 Rxg7# White is mated if he declines the sacrifice:
(2) 26.Kh1 Qh3 (threatening 27…Qxh2#)
27.Qe5 Qf3 (threatening 28…Rh8#)
To prevent immediate mate, White must sacrifice Qe5, but mate follows shortly thereafter. |

| Nov-03-08 | | SuperPatzer77: <johnlspouge: Monday (Very Easy) ...> Hey, JohnlSpouge! You must have made a typo - 27. Qe5 Qf3 (threatening 28...Rh8#) It should be Rg8#. I know you're awfully human after all. Please don't feel bad about having made a typo, OK? JohnlSpouge - How is Canada? I stepped in Niagara Falls, Ontario near New York state (USA) for vacation. I used to be a New Yorker, JohnlSpouge. Well, it's nice to hear from you, JohnlSpouge. By the way, have you watched the 2008 World Chess Championship match between the defending World chess champion Vishy Anand and challenger Vlady Kramnik? It had been awfully exciting. I love this 12-game match. Take care, JohnlSpouge.

| Nov-03-08 | | DoubleCheck: <<newzild>: The line I saw was different to most of the posts below.
Of course, accepting the sacrifice loses quickly, but even after 26.Kh1, apart from all the lengthy analyses posted below, black has this strong shot:
26...Qc6!
And white's toast.>
27. Qb5 Rg1+!!
28. Kxg1 Rg8+
29. Qg5 Rxg5+ mate |

Are you writing from tokoyo (as I've telecommanded?) or have you disobeyed? I'm so disappointed... You'd better be eating sushi, young man...

| Nov-04-08 | | patzer2: For the not so easy Monday puzzle solution, Black plays 25...Rxg2+! for a mating attack. The mate-in-five is easy if White accepts the sham sacrifice. However, it's a bit more difficult after 26. Kf1: 25...Rxg2+ 26. Kh1 (26. Kxg2 Qg4+ 27. Kh1 Qf3+ 28. Kg1 Rg8+ 29. Qg7 Rxg7#) 26... Qh3! 27. Qe5 Rdg8! 28. Rae1 Rg1+ 29. Rxg1 Qf3+ 30. Rg2 Qxg2# |

| | Once: <Eggman> My point is that these combinations are relatively easy to see from the winning side (especially in a puzzle where you know that a tactical shot is coming). But they are harder to see from the losing side one move earlier. Here we have a correspondence game where white does not spot that 25...Rxg2 busts his queen retreat 25. Qb2. |
|
| Nov-04-08 | | gambitfan: I saw quite rapidly the first move 25... ♖xg2 after hesitating with the other move 25... ♕h3?! 26 g3!... Supposing that 26 ♔xg2, it took me a while to find the right "zig zag" of the Queen... 26... ♕g4 27 ♔h1 ♕f3+ 28 ♔g1 ♖g8+ etc... because I loitered a little bit on the - premature - move 26... ♖g8+?! followed by 27 ♔h1 I did not even envisage the white ♔ not taking back the pawn 26 ♔h1! which is the best move in this case |
|
| Nov-07-08 | | patzer of patzers: <DoubleCheck>:On your answer to my question, what happens if 29. Ke2 or 30.Ke2 or 31. Kd2 or 32. Kb1...etc, etc, etc? I know your variation probably uses the most sensible moves, but I just can't let all the other options white has in the variation go. |
