In the card game contract bridge, a takeout double is a low-level conventional call of "Double" over an opponent's bid as a request for partner to bid his best of the unbid suits. The most common takeout double is after an opponent's opening bid of one of a suit where the double shows a hand of nearly opening strength with support for all three unbid suits, at least three cards in each, and shortness in the suit doubled. Rarely at the one-level but potentially at higher levels, partner can instead "Pass" with an appropriate hand, thereby converting the takeout double to a penalty double.

Commonly double is considered takeout whenever one of the following conditions is met (but see balancing double below):

Most common requirements to make a takeout double are:

The most common treatment is that the fewer high card points the hand possesses, the more strict are the distribution requirements (i.e. opponent's suit(s) shorter and unbid suits longer). Most players play that hands with 17-18 high card points should double regardless of distribution (unless the hand is suitable for 1NT overcall). Also, more high-card strength is required when opponents have bid on higher levels (e.g. preempted). Most players play that a double up to the level of 4♥ is takeout, while doubles on higher levels are for penalties or "cooperative" (i.e. the partner is supposed to pass unless his distribution and/or strength indicates that playing a contract of their own on a higher level is a better prospect).

Kyle Blain Perry (born 5 March 1986) is an English footballer who plays as a striker for Lincoln City.

Failing to make the first team at Walsall, he dropped into non-league circles with AFC Telford United, Sutton Coldfield Town, Hednesford Town, and Willenhall Town, before impressing when non-league Chasetown knocked Port Vale out of the FA Cup. Failing to score for the Vale, he dropped down into the Conference National with Mansfield Town in June 2009. The following year he moved on to Tamworth, before signing with Lincoln in summer 2011. He re-joined his former club AFC Telford United on loan in January 2012.

Born in Birmingham, West Midlands, Perry joined the Centre of Excellence at Walsall as a eleven year old and developed through the club's youth structure to be one of seven players, including Matty Fryatt, to sign a three-year scholarship for the club in March 2002; the scholarship commencing at the start to the 2002–03 season. In the third and final year of his scholarship, Perry joined up with then Northern Premier League First Division side Telford United on a temporary basis, scoring twice on his debut: a 2–0 victory at Gresley Rovers on 14 September 2004 the goals being scored against his cousin Dale Belford. He continued with Telford for the remainder of the season, whilst continuing to play for Walsall's reserve team, an issue that concerned Telford's then manager Bernard McNally. Having scored 23 goals for the Bucks as they secured promotion, Perry agreed to join the club permanently in July 2005.

Bradley Raymond "Brad" Gushue, ONL (born June 16, 1980) is a Canadian curler from Mount Pearl, Newfoundland and Labrador. Gushue, along with teammates Russ Howard, Mark Nichols, Jamie Korab and Mike Adam, represented Canada in curling at the 2006 Winter Olympics, where they won the gold medal by defeating Finland 10–4, including a dramatic 6-point sixth end in the final match (even though he missed a draw for 7-points), which was conceded after the 8-end minimum stipulated under Olympic rules.

In 2001, he not only won the provincial championship, but the national championship and world junior championships as well. Gushue was also the alternate for John Morris at the 1998 World Junior Championships which Morris won.

After his outstanding career as a junior, Gushue made an impressive transition into men's curling and his team quickly became a competitive force. Gushue qualified for the 2003 Nokia Brier where he finished with a 6–5 record. By the 2004 Nokia Brier, Gushue proved not only was he one of the best curlers in Newfoundland, but one of the best in Canada, when his team finished with an 8–4 record. The following year, Gushue qualified for the 2005 Tim Hortons Brier where his team once again finished 6–5.
