| Nov-30-09 | | Smothered Mate: Why 15... Qb6 ? |
 |
| Nov-30-09 | | SufferingBruin: 14. Nxd6 instead of Nxh4--explain that! Instead of the exchange, he takes a pawn. I'm sure there is an explanation but the difference between people who know the game and people who are like me lies, I think, in the rational that it's better to snag that d-pawn than be up a whole piece. |

| Nov-30-09 | | Smothered Mate: <SufferingBruin>
I think the difference is more noticing the Qd8. |
|
| Nov-30-09 | | newzild: <SufferingBruin> after 14.Nxh4 Qxh4 15.Nxd6 Qxh2 white doesn't have enough for the pawn. Black lost his way somehow. The bishops should be stronger than the knights in this middlegame. |

| Nov-30-09 | | tommy boy: Excuse me buddies but what means sound or unsound sac? |
|
| Nov-30-09 | | sneaky pete: <tommy boy> A sound sac is when you make a noise like <boom!!> or <wham!!> while sacrificing and an unsound sac is when you sacrifice in silence. They say silence is golden, so when Marshall silently played ... Qg3 the kibitzers showered the board with gold coins. |
|
| Nov-30-09 | | zb2cr: 38. Ne5! simultaneously attacks the Black Queen and unmasks two potential mate threats (by Nf7# and Rd8+). Black can't meet all of these at once. |
|
| Nov-30-09 | | zb2cr: Hi <tommy boy>,
An unsound sacrifice is one that doesn't work--there is at least one line where the opponent can successfully defend. A sound sacrifice is the opposite, where the sacrifice works in all possible lines. |

 | | Chessmensch: According to Fritz the whopping blunder is 36...g6. Any reasonable alternative move would have left white only marginally ahead. |

 | | alexrawlings: <WhiteRook48: 33...Re1+ 34 Rxe1 Qxe1# > you've missed 35 Nc1 but after 35 gxf6 then Black is a queen for a knight up so the game is over anyway. |

 | | Phony Benoni: It is possible to argue that there is no such thing as a sound sacrifice. If a move leads to an advantage in every variation, then playing it is not a sacrifice. But then, you can argue about anything.
Sacrifices are one of those things which everybody recognizes when they see them, but nobody has ever satisfactorily defined. |
|
| Nov-30-09 | | OrangeBishop: Can someone explain what the intention behind 36. ... g6 was? I can't find any benefit to it, and it basically allows the white queen to set up myriad mating threats. |
|
| Nov-30-09 | | sfm: <OrangeBishop: Can someone explain what the intention behind 36. ... g6 was?>
There's something wrong somewhere. Not even beginners play such moves. Instead of 38.Ne5 also the primitive 38.Qxh6+,Kg8 39.Rg1+ wins on the spot without headache.
Maybe he touched the g-pawn or maybe the moves given are incorrect. |
|
| Nov-30-09 | | sfm: Or maybe he imagined that the White king was on a1, so 37.Qxg6 could be answered with 37.-,Bxg2+ |
