A forcing pass auction from a national event many years ago: East: Pass South: Pass West: Pass North: Pass The catch: The points were split 13-24-0-3 around the table. East opened a forcing pass. South made a trap pass holding 24 HCP hoping to double whatever EW bid. Unfortunately he was unable to do this in tempo and West worked out what was going on so ignored his partner's forcing pass and passed. North passed in 4th seat with 3 HCP.
