This is a discussion on New Rules within the online poker forums, in the General Poker section; I'm tired of losing hands that would have won if only we could use 6 or 7 cards. So from now on we can use
1. 3 pairs
Have you ever had this but they were lower than the top pair? I get this several times every single day. Well now I'lll win it.
2. Longer straight
You have a 6 card straight but someone else has a higher card? Well now you'll win it.
3. Very Long Straight
You have a 7 card straight, e.g. A-7 or 8-A or anywhere in between. Well now you'll win it. (This also works with a Straight Flush and a Royal Flush). It is now possible to have 5 and 10 in a straight.
4. Big Flush
You have 6 cards all of the same suit but maybe low cards in the pocket. Very likely no one else does. Well now you'll win it.
5. Biggest Flush
With 7 cards all the same suit no one can possibly beat you. Well now you'll win it.
6. The Big Boat
This is a set with another 3 of a kind. For example, Aces full of Kings full of Aces (AAAKKK) or Deuces full of Threes full of Deuces (222333). Beats a regular Boat. I get this a couple times a day.
7. The Yacht
This is Four of a Kind full of Three of a kind. I have actually had this several times but lost. :-( Well now I'll win it.
I know this will never happen but it's wishful thinking.
Your proposal messes up the whole game because your combinations consist of more than 5 cards.
It is a mathematical unfairness that in some cases a player shows results from the combination of 5 cards but sometimes - of 6 or more cards.
Everybody has to have the same rules. If 6 card combination could count, then a player that has 2 pairs just HAVE to look upon the 2 kickers he has. That is a different game.
