NL Omaha 8 tournament, final table, blinds 25-50

Gambler (3000$): 4567 limps in
Tight player (1000$): A99K calls the SB

Flop: A 2 9

Tight player (with a set of nines and no low) shoves 500$

Gambler thinks for a minute and then raises all in (with a good LO draw and two straight draws)
Tight player calls immediately

Board: A 2 9 5 8

Gambler scoops the pot: HI 56789, LO 65421
Tight player writes: "you fucking luckbox"

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
