And all on the same square, too. Some time ago I came across a puzzle in Chess Today, and while the first move was pretty obvious I managed to get myself sidetracked while working out the details. It was psychologically amusing, and it brought to mind a failure to accurate calculate a vaguely similar queen sac in a game ten years earlier. Both games can be found here, along with a third, even earlier game with yet another sacrifice; all three queen sacs are on the same square and share a family resemblance.
