Im thinking
because I know there is a place in Wan Chai which allows you to play poker there, they got chips, and i saw pppl playin for money there.
they were playin a game like u deal 4 card and the board has 5 card..similar betting pattern as in holdem, but you can use 1 or 2 of your card in the showdown.
it s like a mixed game of holdem + omaha, quite interesting
