zwischenzug

Kg2 gets him out of trouble, but Black has a zwischenzug:

The earliest known use of the term zwischenzug did not occur until after all of these games.

The opponent cannot choose to defend the other piece, or use a zwischenzug to complicate the situation.

The near ubiquity of the zwischenzug makes long combinations all the more rare and impressive.

No one knows when the first zwischenzug was played, but it was evident long before the term itself existed.

As with any fairly common chess tactic, it is impossible to pinpoint when the first zwischenzug was played.

In chess, zwischenzug (German for in-between move) means playing a move that ignores the opponent's move temporarily to create a new threat.

An unexpected check in a forced combination or an overlooked cross-check in a planned series of checks may serve as sort of a zwischenzug, foiling the plan.

Qg1 Nxe5, De Vere's zwischenzug had netted him two more pawns, leaving him with the material advantage of four pawns for a knight.

A forked piece such as the queen might check the enemy king, a zwischenzug, giving time to move the second forked piece to safety on the next move.

The first known use of the term zwischenzug, however, did not occur until 1933, when the prolific American chess authors Fred Reinfeld and Irving Chernev used it in their book Chess Strategy and Tactics.
