| Oct-02-12 | | Abdel Irada: <The HeavenSmile>: I use the cross symbol because it's the most precise glyph. Using a plus risks confusion with the positional evaluation glyphs (  ,  , etc.).Why there appears to be a lot of white space isn't clear. I do tend to put move pairs on separate lines, and a line of white space between variations, but if you're seeing more than that, I have to suspect some sort of browser issue (more likely at my end than yours). |

| Oct-02-12 | | Oxspawn: "Ah!" says Oxspawn, wisely after the event. "So I was sort of right all along. Jolly good." Same problem as yesterday. Not knowing when you have done OK..... |
|
| Oct-02-12 | | Oxspawn: <Abdel Irada> At the risk of revealing myself as a Windows user (Firefox), I think we are seeing what you are putting. I too was puzzled by the fact you brandished a broadsword every time you put someone in check. Thought it was intimidation! Glad you explained that. |

 | | gawain: Easy enough to see that after 40 Qh7+ Kxh7 41 hxg7+ White will be able to promote the pawn and hunt the king. Was I sure that White had a mate? No. Would I have played it over the board? Sure. |
|
| Oct-02-12 | | NewLine: I'm tired of CG "easy" puzzles. They must have fun thinking about the poor patzers sweating their way over the variations of a SEEMINGLY easy puzzle. Well it's NOT FUNNY! The title must fit! You can't put a picture of the ocean titled "puddle"! |
|
| Oct-02-12 | | TheTamale: It took me quite a while. Still, I got it, so the "easy" label fits. Although I did apply the <Phony Benoni> principle of "After 43.g8Q+, There's Gotta Be A Mate In There Somewhere." |
|
| Oct-02-12 | | Castleinthesky: I saw this one intuitively as there is a natural line of attack followed by a nice discovered check. |
|
| Oct-02-12 | | Marmot PFL: I always look at these queen sacrifices, but 95% of the time they don't work. |
|
| Oct-02-12 | | kevin86: If the queen is captured,white will regain the queen and mate soon. |
|
| Oct-02-12 | | BOSTER: <TheBish> <I don't know if I've seen this one before, but I've definitely seen one very similar>.
The same amazing idea-sacr. the queen, which opening the "g" file and allow white rooks to participate in attack was in the game Spielmann-L'Hermet (see the diagram).

It looks like you are not very satisfied. This is why I'll give you another position from game played by Anderssen.White to play.

| Oct-02-12 | | dzechiel: White to move (40?). White is up an exchange. "Easy." The white queen is under attack. I suspect that there are lots of winning moves, but the one I saw first is... 40 Qh7+ Kxh7
On 40...Kf8 41 hxg7+ is a killer. On 40...Kf7 41 Qxg7+ will pick up the black rook. 41 hxg7+ Kg8
Black could try 41...Qxh1 but 42 g8=Q+ Kh6 32 Rxh1# is mate. 42 Rh8+ Kf7 43 g8=Q+ Kf6
On 43...Ke7 44 Qd8+ picks up another rook.
44 Qg5+ Ke6 45 Re8+
snags the knight. There's probably something even better that I don't see. Time to check. |
|
| Oct-02-12 | | MiCrooks: Boster...I like the second one as it is predicated on the double rook mate rather than just regaining the Q in a more open position. Qxh7+ Kxh7 g8(Q+) RxQ (if not Rh3++) then f6+! where either QxB or Kh6 is met by Rh3++ |
|
| Oct-02-12 | | Crispy Seagull: i worked it out all the way to the game's end position, and I agree that white has a superior and winning position, but I don't think it's as cut and dry as a simple resignation. I think a mate from that position is harder than it looks. |
|
| Oct-02-12 | | DarthStapler: Got it |
|
| Oct-02-12 | | DarthStapler: BTW a line I saw (might be some mistakes) is 41... Kg8 42. Rh8+ Kf7 43. g8Q+ Kf6 (43... Ke7 44. Qd8+ ) 44. Rh6+ Kf5 (44... Ng6 Qxg6+ , 44.. Ke7 45. Rg7+ Nf7 46. Rxf7+ Qxf7 47. Qxf7+ Kxf7 48. Rh7+ ) 45. Qg5+ Ke4 46. Rh4+ Kd3 (46... Ng4 47. Rxg4+ ) 47. Rd4+ Ke2 48. Rg2+ Kf1 (48... Ke1 49. Qh4+ ) 49. Rf4 Qxf4 50. exf4 |

| Oct-02-12 | | Patriot: <Crispy Seagull> I think it's a pretty clear win and totally resignable at that level. When it comes to long tournaments, the best thing to do is resign (unless the other player is weak) and take a break before the next round. We're not talking about a small edge for white here--black is completely busted. |
|
| Oct-02-12 | | Patriot: Also, you're right that it's not a trivial mate. Houdini says after Qh7+ it's a mate in 13 moves. But calculating things out to mate isn't always necessary or even recommended. I'm wondering if I over-analyzed the position. Is it critical to calculate what happens after 40...Kf8 or 40...Kf7? I realize that people want to calculate everything they can find because it's a puzzle but somewhere along the way you have to train to avoid calculating non-critical lines. |
|
| Oct-02-12 | | 1stboard: White is going to get a new queen PLUS get black's queen also ....... |
|
| Oct-02-12 | | aidfarh: I got:
40. Qh7+ Kxh7
41. hxg+ Kg8
42. Rh8+ Kf7
After 43. g8=Q+ there might be a mate there somewhere, but I tried playing from that position and it's not straightforward. For me, the easiest is to simplify with 43. Rf8+ Ke7
44. Rxf3 Nxf3
45. g8=Q Nxg1
46. Qxg1

It seems a straightforward win from here. |

 | | paulalbert: Just got back from all day business meetings in NY and went to today's puzzle. Immediate reaction was Qh7ch because then after Kxh7 the critical point is gxh7 is discovered check and after Kg8 ( Qxh1 lets white queen with check and then force mate )42 Rh8ch Kf7 43 g8(Q)with check. I figured that this was far enough and that white had a clearly winning position. I noticed some comments that this wasn't really easy for Tuesday. It is true that there are some subtle points and to win from the g8(Q)ch position you do have be careful to note white's own potential back rank exposure if you do something crazy with the R on g1, for example. I'm not sure there really is a foolproof way to determine the categorization by difficulty of these puzzles and by whom and by what criteria it's done at chessgames. |

| Oct-02-12 | | M.Hassan: <Once:Black is going to retreat to either e7 or f6. Then the move that I really want to play is 44. Qd8+>: Checking on d8 would have been beneficial if the King retreats to e7 and I saw that and hence moved the King to f6 and unprotected Rook can be taken with difficulty if at all: 44.Qd8+ Re7
45.Rh6 Kf7
What next?
I realized that although the King is in wilderness(and defenseless as I thought at first) but can receive help from distant <Secondly, there is a fair amount of shock in a move like 40.Qh7+> I agree that it is a surprising move, but these are Masters who have been playing in tournaments and most probably had seen many shocking moves more futal than this. "Is this the reason to resign?". I say no to this question. The game continuation is not known and one suspects if the resignation was the result of time pressure. Thanks for your post |

| Oct-02-12 | | Abdel Irada: <Oxspawn>: I've often thought that would be perfect for chess in the old romantic style: Brandish a broadsword and cry, "Ahoy! Ahoy! Check!" like the White Knight in _Through The Looking-Glass_. However, I hadn't thought about the "†" symbol as a sword until you mentioned it. Rather, it put me in mind of the little cross used in some histories and genealogies to denote someone's death date. And considering that check is in essence a threat to convert the enemy king into "His Late Majesty," the glyph struck me as appropriate. |
|
| Oct-02-12 | | Abdel Irada: <The game continuation is not known and one suspects if the resignation was the result of time pressure.> I disagree. It seems pretty clear to me that Black resigned because he calculated far enough to see that he lost by force, even if an actual mate was, as you say, 13 moves away. Players at a high enough level to find combinations like this over the board are also strong enough to see the handwriting on the wall when one of them is played. |
|
| Oct-02-12 | | Patriot: <Abdel Irada> I completely agree! And it doesn't take much calculation to see that it is clearly lost for black. After all, where's the move that would cause us to think otherwise? |
