An overcall is a bid made after an opponent opens. Overcalls show a good suit and competitive values, typically 8-16 HCP depending on level and vulnerability.

Example Overcalls

♠AQJ74 ♥K3 ♦974 ♣Q42

After (1♦): 1♠ — Good suit, 11 HCP.

Marginal (Pass or Bid?)

♠Q9742 ♥AK3 ♦74 ♣Q42

2-Level Overcall

♠K3 ♥AKJ74 ♦974 ♣Q42

Vulnerability Considerations

Vul vs Not Vul Adjustment

Not vul Can be lighter

Vul Need sound values

Unfavorable Very sound only

Rule: The more you can lose, the better your hand should be.

Jump Overcalls

Bid Shows

Weak jump 6+ suit, 5-10 HCP (preemptive)

Intermediate 6+ suit, 12-15 HCP (some play)

Strong 16+ (rare, old-fashioned)

Most modern players use weak jump overcalls.
