Hi, this goes to all the Mathematicians out there.

My local Poker Room has a High-Hand Promo called Combi Bet.
You can to place three Bets on certain Hands.
River has to be dealt and you have to have the Winning Hand or show down after the other players folded.
You have 24 hours to make your Combo and are paid the combined Odds of the Hands(like you made a 1€ Bet).There is only one Bet every 24 Hours.
The Odds they offer you are as following. First Number is for Holdem and second for Omaha.(Odds are just multiplied, so yo can make one hand of the whole bet on holdem and the next on Omaha).You can also bet on specific Hands like Nines Full which doesnt make Sense, so I only added bets that make Sense, like Flush with Ace.

One Pair: 1,20 / 1,20
Two Pair: 1,50 /1,50
: 2,25 / 2,25
Straight: 3,00 / 2,20
Flush: 3,50 / 2,50
Full : 4,20 / 2,70
Quads: 15,00 / 10,00
Straight Flush: 35,00 / 20,00
Royal Flush: 50,00 / 40,00

Flush Ace: 5,43 / 2,95
Flush King: 5,6 / 3

Three o.a.K Aces: 6,25 / 2,25
Two Pair Aces: 2,25 / 2,25

What is the most +EV Bet in your Opinions?
Lets say we would stick to either Holdem or Omaha for each Bet and dont mix.We want to play 12 of the 24 hours we have to make our Bet.(6 hours each Day).We don´t want to change our Game anyhow cause of the Bet.
(cause River has to be dealt).What are the Best Hands to bet on=
Do they offered Odds from the Casino represent the real Odds(I mean relative to each other not overall)? We don´t want to make an too easy Bet cause we would be wasting EV and also not an too difficult Bet cause we would maybe play longer to make our Hand or often don´t make our Hand.We just want the Bet that pays us the most longterm if we plan to play 12 out of 24 hours.
and in this time see an estimaed 35 Hands an Hour, so lets say average 400 Hands per Session. Another Thought is that maybe its better to include Flushes instead of Straights cause Straights go to showdown less often if Flush/Full shows on the Board.

Would apprecciate if someone could come up with a solution there.

Then you would need to compare your own hand history for your winning hands at the river, to these offered odds, and see where you have an edge. This might be hard to do for your live games since you don't have them recorded.

Your chance to win with a hand is not the same as the calculated probability of being dealt that hand. It depends a lot on your own playing style, as well as the relative strength of the hand (i.e. winning with a pair at the river isn't very likely even though you will have one a lot).
