Can you force instant resignation?

  • #1

    I admit that White will win this game with almost every move, but the given position contains a tacical blow which resulted in Black's immediate resignation. I am happy to have found it in a 3 min blitz game; which move was it?

  • #2

    easy

  • #3

    Very Nice, Thanx.

    Nice. It's so cool when queen sacs actually work out. Usually when I do it, I fail miserably and lose the game.

  • #5

    Those rooks sure do love that 7th rank! Cool

  • #6

    nice, by the way though, I wouldn't class that as a sacrifice of the queen. It's hardly a sacrifice when if the opponent accepts your offer you have forced mate in two or three. I would just see that as a combination.

  • #7

    yep it was clearly a win-win sitaution for white,black should have considered g4 to sacrifice queens and try to push some kind of a drawn later in the game

    Nice puzzle, thanks for sharing it with us.

    You do realize that White still has a forced mate if Black declines, right? [See Torkii's post]

    While I can see why you wouldn't call that a sacrifice, it still is considered one. At least imo, it's "only" a combination if White gets the material back, and it's a sacrifice if White gets a forced mate or "immaterial" compensation.

    Thank you everyone for your comments, especially dmeng!

    Yes, it's definitely a sacrifice. I think the difference swestland means is the one between this sac which directly ends the game and the more intuitive or positional one, where you get some compensation like a heavy attack for instance, but the game still goes on. Still both types are genuine sacrifices.

    About declining the sac with 1...Rf7 (or 1...Qg2+ and 2...Rf7): I think White's quickest win in this case is (1...Rf7) 2.Rxf7 gxh5 3.Rc8 f4 4.Ra8+ Qc8 5.Rac8#  Of course, instead of the Qc8 maneuvre, Black can give some pointless check instead, the number of moves remains the same...

  • #12

    a worthy sacrifice

  • #13

  • #14

    nice

  • #15

    that was 222 easy! nice puzzle

  • #16

    Really nice one Torkil.....one might see this sacrifice in a long game...but to see it in a blitz, now that is impressive...keep up the good work

    Gotta love the queen sac. I saw it instantly, but the question is whether or not I could set it up in an actual game. Well played.

     That there is a mate even if black declines the offer of the queen strengthens my argument that it is not a sacrifice. I am using Silman's definitions by the way (from his 1993 edition of How to reassess your chess). Silman defines a sacrifice as:

    "The voluntary exchange of material for the purpose of obtaining a more favourable advantage than the material investment. Unlike a combination, a sacrifice is not a cut and dried affair, and there is usually an element of uncertainty associated with it." (Silman, 1993)

    There is no uncertainty here. If black accepts the "sacrifice" he is mated; even if he declines he is mated!!

    It's still a great spot though - especially in a blitz game.
