Islam & Poker - Darurah and Hajah

[malorum]

Just a question for the Islamic Jurists out there.
It is clear that Gambling is haram (unlawful), but is it possible for the Poker Pro with a large family to cite Hajah (need) as a justification for his conduct.

Relevant Fatwa are found in relation to the use of interest based mortgages by muslims in the UK. It is suggested by some jurists that the need (Hajah) for security can be treated in the same way as Darurah (necessity), thus in effect providing a defence against the otherwise unlawful conduct of borrowing money on interest to buy a house.
