re: Poker & a question about omaha
It was one of the first mistakes I made when I played Omaha. Card usage.
Holdem you can use 0, 1, or 2 of the cards in your hand. Obviously if you use 0 you can only tie with anyone who can't beat the board either.
Omaha is different.
You get 4 cards instead of just 2. Many people think that means you get to use all your cards when the first play. Rude awakening when their full house ends up only being a trips.
When the light bulb comes on that you can only use 2 cards instead of 4 the other rude awakening happens. You get the straight flush with the 7c in you hand and the only dealer says you only have Jack high flush. What's up with that?
The flipside Ohama difference. You HAVE to use 2 Cards from you hand. You can't just use one card.
So let's review
Texas Holdem. Dealt Cards to you 2. Amount of cards in your hand that are playable.
Omaha. Dealt Cards to you 4. Amount of cards used.
Maximum: 2 of 4 in your hand.
Minimum: 2 of 4 in your hand.
