The differences between Omaha and Texas Holdem
Compared with Texas Hold'em, Omaha focuses on computing brand, rather than calculating people.
Hands must be high, if the start is not good to throw away four cards, no loss, only good cards before playing, waiting for the next chip to retain a chance.
There are four cards Shun number is not a good card, because you can only use two of them, the other two but reduces the possibility of the existence of your hand into. For the board is the same reason, because only three cards can be used.
If you buy some marked cards, and wear the special contact lenses or luminous sunglasses, you can see the marks on the back of the playing cards.
