Thanks Buzz for doing the simulation.This page shows all important Poker Odds and Poker probabilities. Maybe that is correct, but let's await further news from heehaww. Thus, the correct answer to the original question is: So of the C(5,2)=10 ways that a non-Royal straight flush can be divided between the player's hand and the board, 4 of them will have the bottom card in the player's hand and 6 of them will have the bottom card on the board. This applies to all the non-Royal straight flushes, since, of course, there is no 'higher' card to a Royal Flush. If the bottom card of the straight flush in question is in the player's hand, then the 'next higher' straight flush card is 'allowed' insofar as it does not give the player a higher straight flush by the rules of Omaha.Įquivalently, if the bottom card of the straight flush in question in on the board, then the 'next higher' straight flush card is 'not allowed' insofar as it would give the player this higher straight flush by the rules of Omaha. Heehaww makes a very good point! Let me see if I am following. Remaining cards can be anything: 47 other cards of which 2 go to player and 2 go to board.

So we need to divvy up one of the 40 possible straight flushes so that 2 of the 5 cards get dealt to player and the other 3 appear on the board.

Straight flush: any of 40 five-card combinations when suits are taken into account (including royal flushes - clearly if royal flushes are to be excluded, change the 40 below to 36). Omaha: use exactly two cards from your hand of four cards + use three cards from a community board of five cards (I apologize in advance if anyone takes offense to my posting in this nature.) Once the real experts in this field post the correct answer, I can learn how to improve my thinking on these types of questions. But I readily admit that this type of calculation is not my strong suit and the answer below could well be wrong.
