Board (bridge)

In duplicate bridge, a board is an item of equipment that holds one deal, or one deck of 52 cards distributed in four hands of 13 cards each. The design permits the entire deal of four hands to be passed, carried or stacked securely with the cards hidden from view in four pockets. This is required for duplicate bridge tournaments, where the same deal is played several times and so the composition of each hand must be preserved during and after each play of each deal.

Each board is usually marked with the following information: board number – (usually in the sequence '1' to '32') identifies the deal and helps to order the play of multiple deals; compass directions – used to match the four hands to the four players at a table; dealer – designates which player is the "dealer"; this designates the player who is to make the first call of the auction; vulnerability – often represented by color code: a "vulnerable" partnership is usually shown in red and a "not vulnerable" partnership in green, white or no color. Most designs include a slot or pocket to hold a paper travelling score sheet.

Board foot

The board-foot is a specialized unit of measure for the volume of lumber in the United States and Canada. It is the volume of a one-foot length of a board one foot wide and one inch thick.

Board-foot can be abbreviated FBM (for "foot, board measure"), BDFT, or BF. Thousand board-feet can be abbreviated as MFBM, MBFT, or MBF. Similarly, million board-feet can be abbreviated as MMFBM, MMBFT, or MMBF.

In Australia and New Zealand the term super foot or superficial foot was used to mean the same.

One board-foot equals:

Board foot is the unit of measure for rough lumber (before drying and planing with no adjustments) or planed/surfaced lumber. An example of planed lumber is softwood 2 × 4 lumber one would buy at a large lumber retailer. The 2 × 4 is actually only 1 ¹⁄₂ in × 3 ¹⁄₂ in (38 mm × 89 mm) but the dimensions for the lumber when purchased wholesale could still be represented as full 2 × 4 lumber, although the "standard" can vary between vendors. This means that nominal lumber includes air space around the physical board when calculating board feet in some situations, while the true measurement of "board feet" should be limited to the actual dimensions of the board.
