| Jun-19-13 | | Jamboree: Can someone explain why white resigned in the final position? Sure, if he's forced to sac the exchange back, he'll go into an endgame two pawns down. But black still must demonstrate that he can convert the win, which is not necessarily a trivial task. And even if white doesn't sac the exchange back -- where is black's forced mate? Say in the first option white tries 28. Rxd3 Nxd3 29. Rf1 Ne5 30. Qe4 Nf3+ 31. Kh1 ...and now what? Admittedly a better endgame for black, but hardly worth resigning over at this stage. Does black have an insta-win that I'm missing? |

| Jun-19-13 | | Gogia: @ Jamboree: engine evaluation shows - 3.45. it goes like: 28. Rxd3 -3.54/16 Nxd3 +3.42/14 29. Rf1 -3.79/18 Nf4 +3.79/17 30. Qa4 -3.79/17 Qe7 +3.96/17 31. Qe4 -3.94/16 Qxg5 +3.96/16 32. Re1 -4.27/16 Rf5 +5.11/16 etc
Not hard for black to take this. |

| Jun-19-13 | | morfishine: Hello <Jamboree> On your question: <Does black have an insta-win that I'm missing?> 29...Nf4 looks stronger than 29...Ne5 Although not an "insta-win" 29...Nf4 emphasizes White's weak pawns after 30.
Qe4 Nxg2 31.Kxg2 Qf5 |
|
| Jun-19-13 | | Qxf7: Sure. Suppose white makes some random move that doesn't drop his queen. For example 28 Qc3, Nxg3.
White's completely screwed now. The threat on f2 is going to get him checkmated if he doesn't defend it, but anything he tries is going to hang the exchange (on e1) sending him into the endgame down 2 pawns and a piece. If he sacs the exchange right away, he still can't recapture after 29... Nxd3, because that drops material to Qxf2! When your best case scenario is down a piece and 2 pawns for zero compensation, it's probably time to resign. |

| Jun-19-13 | | numbersguy70: 27...Nxg2, if followed by 28. Kxg2, allows 28...Bh3+!! 29. Kxh3 Qf3, with checks forcing white king into corner and black rook to f2, where mate cannot be prevented. |

| Jun-19-13 | | SimonWebbsTiger: I would think the obvious answer to <Jamboree> would be Dam resigned a hopeless position against a stronger opponent in an open. Dam, from the Netherlands, was about 2300 at the time whilst Norwood was 2400+ and an IM (later GM). |

 | | Phony Benoni: Capitulation was not premature. Black played the Benoni. Resignation was only a matter of time. Today, it happened to be White's turn. People are showing admirable restraint about the pun, so maybe I should bring this up: http://en.wikipedia.org/wiki/The_Da...(film) |

| Jun-19-13 | | morfishine: <Phony Benoni> On your interesting comment <People are showing admirable restraint about the pun, so maybe I should bring this up...> I figured it was referencing the British WWII bomber Avro Lancaster, which was the only plane big enough to carry the 'Black Buster' bomb (8,000 lbs) & the 'Grand Slam' bomb (22,000 lbs). Maybe the best pun would drop the 's' and be 'DamBuster' |

| Jun-19-13 | | Magic Castle: Why white resigned? If white captures the bishop with the rook, the rook is captured by the knight and the knight is captured by the white queen, Then Qf2+ and the other rook falls and the h pawn too. So black is ahead in quality and 3 pawns. If white refused the sac. Then simply knight takes bishop threatening the rook and Qf2+. If the king captures the knight, Qf2 + and mate cannot be avoided with 3 piece (queen, rook and bishop) on the attack. |
