Omaha Poker is the second most popular form of poker on the internet after Texas Holdem.
The fundamental difference is that each player is dealt four cards instead of two as in Texas Holdem and to play, you must always use two of the four cards that are dealt to you.
It is a poker that is played mainly Pot Limit where the maximum bet that can be done is dictated by the amount in the pot at all times.
Omaha is in turn two variants: Omaha Hi (commonly known as Omaha, Omaha Pot Limit or PLO) and Omaha Hi-Lo.
