| TTLump: <treacheroust: Why doesn't black play Qe4 on move 32?> because that would be an illegal move. |
|
| Nov-30-06 |
| TTLump: <pggarner: Why can't black play 36...Qd2, winning the white rook a few moves earlier?> because 37.Rxe5 lets White keep the rook and possibly even the game. |

| Nezhmetdinov: why not simply 32... Qf2? |

| TTLump: <ounos: Why not 22. f6 ?> interesting idea. what were you planning after 22... gxf6 23.Nxf6 Ng5 ... ? If I were White, I might be concerned about opening up the g-file in front of my King, especially where Blacks's rooks can be mobilized fairly quickly. |

| slowcrawl: I think 31..Qc5+ 32.Kh1 Qe3 works too. |

| 48123: Well i definitely got the idea right... the queen can't move from the rank 1 or mate by the rook when the king is on h1 at least i think that's right >.< |

| Marco65: This puzzle requires a lot of precision in that it has many moves only apparently winning and I went astray. But it seems I'm not alone. 32...Qf6 doesn't win because of 33.h4
36...Qd2 doesn't win because of 37.Rxe5
And 37...Qe2 that I thought would win (38.Kg1 Qf2+ 39.Kh1 Qf1+) doesn't win because of 38.Rf5! |

| bane77: <Nezhmetdinov> 32...Qf2 33.Qg1. |

| JohnNash: for black, in this puzzle, can someone evaluate on this:
31....Qc5+
32. Kh1 Qe3 (forking Q and R plus threat to mate at Rf1 if Q moves out of the rank |

| JohnNash: don't worry guys, got the answer, all i have to do is read the kibitzs |

| Fisheremon: <bane77: <Nezhmetdinov> 32...Qf2 33.Qg1.> 33...Qe2 again gives a win for Black. The right move is 33. Qxf2 and White wins. |

| YouRang: <slowcrawl: I think 31..Qc5+ 32.Kh1 Qe3 works too.> *Groan* So did I. We were wrong (see my earlier post).
31...Qc5+ 32. Kh1 Qe3 33. Qxe3!
You're thinking 33...Rf1 is mate, right? Phhfft. 34. Qg1 and you've lost a rook. |

| Fisheremon: <syracrophy: Nice game. A puzzle with the same theme> Nice, but do you think pawns f and g may be dropped ? |

| Phony Benoni: <pggarner> 36...Qd2 37.Rxe5. No, I'm not Steinitz or Korchnoi; I just read the previous notes. It's another easy one to fall into. I know. Guess I'm not Morphy either. |

| Phony Benoni: Going through some old issues of "Michigan Chess", I came across a favorite combination which features more of a "spiral staircase" manuever:

BLACK TO PLAY. This is from Landon Davis (1894)--Attila Lehtozky (2071), Michigan Open, 1983. White might have some less bad moves than what he plays here, but he doesn't have any good ones. <44...Qc4+ 45.Ke3>
He really needs to keep the f3 pawn protected. And if 45.Rd3? We're coming to that; be patient. <45.Ke3 Qc5+ 46.Ke2 Qb5+ 47.Ke3 Qb6+ 48.Ke2 Qxb2+ 49.Rd2 Qb5+ 50.Ke3 Qc5+ 51.Ke2 Qc4+ 52.Ke3 Qxc3+ 53.Rd3> Finally.
<53...Rxf3+! 54.Kxf3 Qxd3#!> |

| Fisheremon: <Phony Benoni: Going through some old issues of "Michigan Chess"> In your line 46. Kd2 leads to a minimal advantage of White, or much better 45. Kd2 equalizes the game at once. |

| Phony Benoni: <Fisheremon> 45.Kd2 does look a bit better for White than the game, since 45...Rxf3 can be answered by 46.Qd8+ Rf8 47.Qxd6. However, I don't think that 46.Kd2 is so effective; with the Black queen on c5, the d6 pawn is protected. In either case, I think Black is at least some better, but 45.Kd2 was probably the best chance for White. |

However, I don't think that 46.Kd2 is so effective; with the Black queen on c5, the d6 pawn is protected.> Let's have a look at the main line with 46. Kd2: 46...Rxf3 47. Kc2 Qc6 48. Kc1 Qb6 49. Qh6 Qe3+ 50. Qxe3 Rxe3 51. Rxd6 Rxe4 and a further analysis shows that the rooks ending is drawn. |

| Phony Benoni: <Fisheremon> <46. Kd2 Rxf3 47. Kc2 Qc6 48. Kc1 Qb6 49. Qh6 Qe3+ 50. Qxe3 Rxe3 51. Rxd6 Rxe4 and a further analysis shows that the rooks ending is drawn.> OK. I think Black could have played better in there (47...Rf2+ for instance), but let's look at the resulting position.

Maybe this is a draw; I haven't analyzed it closely. But my judgment is that White is going to have to work very hard to get one; he's a pawn down and I don't see any particular compensation for it. In particular, the rook on g2 is very passively posted. Still, it is better than the game continuation, though. |

| Fisheremon: <Phony Benoni> In the worse variation 46. Kd2 Rxf3 47. Kc2, 47...Rf2+ quite interesting, but I also analysed as 48. Rd2 Rf4 49. Qh3 Qc4+ 50. b3 Qxe4+ 51. Kb2 Rh4 52. Qe6+ Kh7 53. Qxd6 Rh1 54. Ka3 Qf4 55. Qe6 e4 56. Rde2 Rh4 57. Kb2 here are three plans 57...b5, 57...a5 or try to attack by the first horizontal. In each case White has enough resources to gain a draw. Moreover I don't see Black's advantage at all in the variation 45. Kd2. |
