Time-lapse photography is a technique whereby the frequency at which film frames are captured (the frame rate) is much lower than that used to view the sequence. When played at normal speed, time appears to be moving faster and thus lapsing. For example, an image of a scene may be captured once every second, then played back at 30 frames per second; the result is an apparent 30 times speed increase. In a similar manner, film can also be played at a much lower rate than it was captured at, slowing down fast action, as slow motion or high-speed photography.

Processes that would normally appear subtle to the human eye, e.g. the motion of the sun and stars in the sky or plant growth, become very pronounced. Time-lapse is the extreme version of the cinematography technique of undercranking. Stop motion animation is a comparable technique; a subject that does not actually move, such as a puppet, can repeatedly be moved manually by a small distance and photographed; the photographs can be played back as a film, showing the subject appearing to move.

Time-lapse bridge is a technique whereby the frequency at which a match is captured (the boards rate) is much lower than that used to view the whole match. These are the boards included in the time-lapse bridge of the match for the BB Semifinals (R5) between USA2 vs Bulgaria:

Bulgaria USA 2

SF Round 5:

The set ended 30 Bulgaria – 33 USA2 IMP.

Board 11

These were ahollan’s explanations in the VG BBO Table.

ahollan2→: 1club suit = 16+unbal or 17+BAL
ahollan2→: 1Heart Suit = FG 5+Spade Suit

So Moss-Grue played 4Spade Suit and only lose three aces, +620.

At the other table.

South chose to open with a spade weak bid, and North jumped to game. Fleisher decided to act, and doubled. Martel asked him to pick the suit, and Fleisher chose diamonds.

Karakolev misjudged and said 5Spade Suit, he was doubled and had to pay one down. A lose of 10 IMPS. 5Diamond Suitcan pay more than 4Spade Suit.

A commentator added:

patricck→: Bulgaria were pushed to 5Spade Suit on board 11 by an EW 5Diamond Suit bid, but they really should have taken the penalty. 5Diamond Suitwould easily have cost more than the game

Board 12

West opened showing a weak major, and his partner chose to pass. Declarer made 11 tricks. In the other room, with the same opening bid, East invited to game and West accepted, 6 IMPs to Bulgaria.

Board 14 Fleisher & Martel decided to play 3NT, made 10 tricks. At the other table Bulgaria found the diamond slam: 

These were ahollan’s explanations in the VG BBO Table: Grue opened 1NT (14-16), 2Diamond Suit showed 5 or more heart cards. 3Spade Suit asked for four heart cards, and 3NT denied them. After having some more information about his partner’s hand Stefavnov decided to play the diamond slam.

This is what the commentators wrote:

  • fuquay→Here 6Diamond Suit makes with 2-2 Diamond Suit, or 3-1 Diamond Suit and 3- 3club suit. Or stiff Diamond Suit Q of course.
  • patricck→: Yes, 6Diamond Suit is quite good contract
  • bobholl→: a lot better than 3NT
  • patricck→: 2-2Diamond Suit or 3-1 with singleton Queen happens 52.5% of the time
  • vugraphc1→: In 52.5% of the time, (it works every time :))
  • patricck→Mesa : Some of the time when the diamonds are not singleton queen you get to make with a 3-3 club break anyway
  • ady→Mesa : I would a expect a few imps for USA here
  • patricck→Mesa : I’m going to say 6Diamond Suit will make about 65% of the time
  • bobholl→Mesa : and on a Spade Suit lead it is even made with club suit 42

Lead: club suit2

Declarer played dummy’s club suitA, continued with a diamond to the ace, watching North’s Diamond Suit10. And continued with a diamond to the valet and queen. Down one and a 10 IMPs swing for USA 2.

Now the comments were:

  • ahollan2→: after short club suit lead not surprised he played for Diamond Suit3-1
  • serhat→: will he lead singleton with Qxx?
  • stc→: dec read correctly the lead as a single and decided to take the finesse
  • ahollan2→: but would he lead stiff with Diamond SuitQxx
  • ahollan2→: garozzo said if you don’t lead singleton you don’t have one [or it is singleton trump]
  • stc→: a very expensive decision, minus 10 instead of plus ten
