Zwischenzug

Zwischenzug (German for "in-between move") is an intermediate move played before an expected or forced move, often changing the evaluation of the position.

Key Characteristics

Disrupting Expectations

Instead of making the expected move, you insert a forcing move first.

Gaining Tempo

The zwischenzug often gains time or material.

Changing the Position

The in-between move alters the position favorably before continuing the sequence.

Common Types

1. Check as Zwischenzug: Giving check before recapturing
2. Capture with Threat: Capturing while creating a new threat
3. Attack Before Defense: Attacking before defending
4. Intermediate Exchange: Trading pieces before the expected move

Examples

• Before recapturing, give check to improve your position
• Before moving a attacked piece, create a bigger threat
• Before defending, counter-attack

Why It Works

• Opponents often calculate only the expected sequence
• Forces the opponent to respond to a new threat
• Can win material or improve position
• Disrupts the opponent's plans

Defending Against Zwischenzug

• Always calculate forcing moves in between
• Don't assume the opponent will make the expected move
• Look for checks, captures, and threats
• Calculate all forcing sequences completely

Practice Tips

• Always look for forcing moves before making expected moves
• Practice calculating complete sequences
• Study games featuring zwischenzug
• Don't rush to make obvious moves

Zwischenzug is a sophisticated tactic that separates strong players from beginners.
