Jul-10-15 | | Marmot PFL: A 20 move win in the QGD, not so common. |

Jul-10-15 | | fisayo123: An uninspired Lu Shanglei is like a 1500 player, so not surprising. |

Jul-09-16 | | Patriot: I was thinking 17.Bxc6 Bxc6 18.d5
18...Bxd5 19.Nxd5 exd5 20.Qxe8+ Qxe8 21.Rxe8+ Rxe8 22.Nxh4 18...exd5 19.Qxe8+ Qxe8 20.Rxe8+ Rxe8 21.Nxh4 |

Jul-09-16 | | Patriot: That's what I get for trying to solve a Saturday problem quickly and when I'm tired! 18...exd5 19.Qxe8+ Bxe8 wins
But at least my 18...Bxd5 line is accurate... |
|
Jul-09-16 | | dfcx: Black queen is tired up defending the bishop. Attacking on the queen gains a piece for white. 17.d5 exd5 18.Rxd5 Qe7 19.Qd1 Qf6 (against 20.Bh7+) 20.g3 wins the bishop. |
|
Jul-09-16 | | not not: I read once Karpov's "My 50 best games" and he said something like "when white has isolated d4 pawn, d5 push is a standard beginning of attack" there are quite a few games of Karpov's with isolated d4 pawn marching to d5 starting attack, e.g. Karpov vs Timman, 1981
so the puzzle is rather chess knowledge puzzle then over-the-board puzzle there is a collection on chessgames.com made by user isolani listing all d5-push attacks Game Collection: isolani |
|
Jul-09-16 | | not not: sorry the user's name is bharat123; his collection shows "isolated queen pawn games", hence the name of collection |

Jul-09-16 | | diagonalley: white can capture two minor pieces for a rook... (i assume that at this level, that is enough for black to resign?) |
|
Jul-09-16 | | AlicesKnight: Saw the first part but missed the effect of "simple" Qd2 (laziness on my part) while looking K-side. <diagonally> seems to be right (again). |
|
Jul-09-16 | | leRevenant: Black resigned, not wanting to be humiliated by too much more horseplay. |

If Black guards the bishop with a rook, 21. Rxb7 Rxb7 22. Bxc6 also forks or skewers Black's rooks, so White comes out a full piece up. Am I wrong? |
|
Jul-09-16 | | drollere: if 20. ... Bc8, then 21. Bh7+ wins the exchange.
confucius say, "beware of queen facing opposing rooks behind single opposing piece screen." |

Jul-09-16 | | YouRang: I tried just about everything except <17.d5!>. But to my credit, my chess instincts correctly assessed that I was going nowhere... |

Jul-09-16 | | agb2002: White has a bishop and a knight for the bishop pair. Black is probably considering the maneuver Nb4-d5 after protecting the LSB. My head is off today (probably too much sun at the beach this morning) but my guts say 17.d5 (17.Bb1 Nb4) 17... exd5 (17... Nb4 18.dxe6 Qe7 19.Nxh4 Qxh4 20.exf7+ Kxf7 21.Rd7+ Re7 22.Rxb7 Rxb7 23.Qxc6 + -) 18.Nxd5 Bf6 (due to 19.Nxh4 Qxh4 20.Nc7) 19.Qf3 with a much better position. For example, 19... Bxb2 20.Nb4 Qc7 21.Nxc6 Rxe4 22.Qxe4 Bxc6 23.Qc2 + -. |
