| Dave Murray: Is 18. Nxf7 winning? how does he defend against Qh8# and Nh6# threats? |
 |
| Dec-29-04 |
| Dave Murray: Never mind, there is no Nh6 mate, cause his bishop is on f6. |

| Novice713: I found the solution to this one without help, but it took me a while. Ever notice that almost every puzzle is described as "easy" by someone? I can't solve all puzzles easily yet, but getting better. Interesting combination, first the queen sacrifice then the double check by the knight and bishop. |

| Gregor Samsa Mendel: I think <Dave> meant that after 18.Nxf7 Qxf6 19.Nh6+ there's no mate, because the bishop on f6 blocks the long diagonal. |

| fgh: Solved in 0.3 seconds because I know this one by heart ;-) |

| catlover: I solved it in .025 seconds, give or take about five minutes. :-) Double checks sure are powerful.
Black's woes appear to begin with 12...Nd5. |

| Jatayu: good puzzle. It's easy if you've seen the pattern, but if you haven't then it's one to learn. |

| mineiro: What about:
18.Ng4 Bxf6 19.Nxf6+ Kh8 (or Kg7), 20.Ng4+ Kg8, 21.Nh6#
??? |

| admiralnemo: Although not nearly as lethal as the solution as played, and, in comparison, quite crude, I think that 18.Ng4 BxQ 19.NxB+ Kg7 (Kh8) 20.Ne8+ Kg8 21.NxQ Rc8 22.Nxe6 fxe6 is good, since it leaves white up a pawn and black with an isolated e pawn, and of course I only mention this line because I missed the proper solution today :( |

| Madman99X: I figured the queen sac in the back corner because that puts the queen in a bad spot, but I couldn't figure out the finishing move. On the subject of somebody finding each puzzle easy: I imagine that different types of puzzles are easier for some and not to much for others. I solved yesterday's at first glance, and for some reason I couldn't find the third move today. |

| blunderqueenagain: Gah! I can't believe I missed this one. I was doing OK this week, but today I couldn't find the second move. I knew I wanted to 1) execute a double check against the king, and 2) get the knight to end up on h6, but for some reason all I looked at were 19. Nxg4 and 19. Ng6, both of which achieve one of the goals but not the other, and neither of which win. I'm kicking myself for missing it. |

| Nickisimo: <Novice 713 Ever notice that almost every puzzle is described as "easy" by someone?>
Yeah, ignore them. They're either very good players or they're lying. :) I got this one, but it took me at least 45.72 seconds to calculate the double check and then mate on h6. So according to some kibitzers on here I'm at least 2000x worse than the pros on here. |

| RisingChamp: I stink-I took about a minute to get my solution and it wasnt even a mate-just winning a pice with 18 Ng4? Bxf6 19 Nxf6+ Kg7 20 Nd5+ ksomewhere 21 Nxc7 Rc8 22 a3 and white ends up a piece ahead. |

| kevin86: I first tried the other double check at g6-fearing that the king could escape the open hole at f7-in fact,the mating knight guards that square. Note:the other bishop is a decoy. |

| notyetagm: Nice problem, a <decoy> (18  h8+!!) into a <double check> (19  xf7++) that leads to the mating pattern known as <Blackburne's other mate> (20 h6#). I was trying to arrange just such a mate when I saw the tell-tale pattern of  b2-e5-f6. Eventually I realized that 19 xf7++ does the trick.Once again, it pays to know your basic mating patterns cold. |

|
| notyetagm: Black voluntarily makes a hole on f6 near his king (13 ... g6?!) and then removes its piece defenders (14 ... d6?! and 16 ... c7??). The weak square is then occupied by the White queen (17 f6) and a mating pattern has been created. This game shows the old saying that a chess patzer wants pieces and a <chess master wants squares>. |

Bxf6 19 Nxf6+ Kg7 20 Nd5+ ksomewhere 21 Nxc7 Rc8 22 a3 and white ends up a piece ahead.> I came up with something similar. 18. d7 xf6 19. xf6+  g7 20. e8+ g8 21. xc7  c8 22. e5 That is, until I saw that pushing the f pawn followed by the e pawn cuts off the bishop's defense. |

| euripides: Alekhine somewhere comments on how rare a really new tactical idea is in chess. I think this is something of the kind - the idea of the Nh6 mate is familiar, but the idea of Qh8 rather than Qg7 to secure a double check on the next move is a wrinkle I haven't seen before. Somewhere Larry Evans has a nice idea about the cases where you should move the queen one move further than you initially think. Compliments to CG for an interesting position. |

| patzer2: Bravo! Today's neat problem solution involves a key deflection 18. Qh8+!, immediatley followed up by "double discovered check" and mate. After the interesting alternative 18. 18.Ng4!? BxQ 19.NxB+ Kg7 (Kh8) 20.Ne8+ Kg8 21.NxQ Rc8 22. Ba3! + -, White should win. However, 18. Qh8+! is obviously the better choice, as it is quicker and clearly decisive. |
|
| Dec-29-04 |
| jkiipli: <mineiro> your variation leaves black 20...f6, that's why I discarded this line and went 18.Ng4 BxQ 19.NxB+ Kg7 20.Nd5+ regaining queen with materail advatage |
