In the layout shown in Example 10, the threats ({{Spades}}J and {{Hearts}}Q) are divided between the North and South hands and East holds the guards in the threat suits. Furthermore, North holds a winner in each threat suit and South holds no winner in either threat suit.

Suppose that South leads the squeeze card, the {{Diamonds}}A,  in the position shown. East simply discards either heart, because the South hand can neither retain nor regain the lead, and the North hand must eventually lose the {{Spades}}J to the {{Spades}}K.

The solution is to unblock the {{Hearts}}A before leading to the {{Diamonds}}A. After the unblock, the position is as shown in Example 11. The unblock of the {{Hearts}}A transposes Example 10 into Example 11, a simple automatic squeeze with the {{Hearts}}Q positioned to exert pressure against East. Compare Example 11 with Example 4, which shows the same basic position.

The unblocking solution remains the same even if the East and West hands were interchanged.

The play, prior to the squeeze card, of the winner that blocks South's threat is called the ''Vienna coup''. The term has long been regarded as unduly connoting brilliance: "In short, the aura of glamor which has always seemed to surround this play is wholly fictitious."<ref>Clyde E.
