An optional double is a conventional double made after an opponent has opened the bidding with a preempt. The double shows a fairly balanced hand and general HCP strength (usually at least 14+). Partner has the option of either bidding a good suit or passing the double for penalties.

Optional doubles are most useful after three-level (and higher) preempts. Weak two-bids are better defended with takeout doubles.
