Should the opponents redouble the contract, conventional wisdom recommends running like a "stripe-tailed ape" to a sacrificial contract.
Examples of the scoring difference between a doubled game contract (making an overtrick) versus a small slam:
Contract | Vulnerable | Result | Score |
---|---|---|---|
5/-X | Not vul. | Made 6 | 650 |
6/ | Not vul. | Made 6 | 920 |
5/-X | Vul. | Made 6 | 950 |
6/ | Vul. | Made 6 | 1370 |
4/-X | Not vul. | Made 6 | 790 |
5/-X | Not vul. | Made 6 | 750 |
6/ | Not vul. | Made 6 | 980 |
4/-X | Vul. | Made 6 | 1190 |
5/-X | Vul. | Made 6 | 1050 |
6/ | Vul. | Made 6 | 1430 |
The following deal comes from a team game during the 1997 ACBL Fall Nationals. It was originally reported by Phillip Alder, 1 now the New York Times bridge columnist.

The late American expert and bidding theorist John Lowenthal is credited with devising the stripe-tailed ape double.
