Definition of upward
Of the upwards is an expression you will hear on the Pot Limit Omaha(PLO). In Omaha games, you will receive 4 hidden cards (not 2 as in Hold’em). When you have 4 cards in a row, it will sound like you have upwards. Whether it's 2-3-4-5 or 7-8-9-10 or J-Q-K-A, they are upwards. The upwards are fairly strong hands. Obviously, the higher your cards are, the stronger your hand will be. The reason for their strength is that this type of hand connects well with many boards and will give you many options for making a sequence.
If your upwards are matched, their value is even higher.
If you take a hand that is "almost" a upward, a hand like QKJ2, that hand will have 50% equity against any 4 cards your opponent might have. If you have a upward by replacing the 2 with a 10 (so T-J-Q-K), you now have a 55% equity against any two cards your opponent might have. And if your amount is double-matched (KQJT with 2 hearts and 2 spades), your equity now increases to 59% against any 4 cards your opponent might have. Small differences that will have a big impact on your potential profits.
