About OB
OB is short for an objection, as in someone raising an ob. Collins players use it for the B, a tile that is hard to place in two letters.

OB scores 4 points
Before any bonus squares: O 1 + B 3 = 4. On a double-word square that's 8, on a triple-word 12, and every letter bonus under one of these tiles is applied first.
Example: OB as the first play
Later in the game, put the B on a 3L square and OB is worth 10 before any word bonus.
