  1. The occurrence probabilities of the different types of Holdem flops can be a little confusing because about half of the possible flops contain more than one of the types that are shown. Since each set of properties is counted on its own and compared individually to the 22,100 possible three card combinations, the total of all the various flops.

  3. Texas Hold’em features 169 different starting hands. Despite this, there are only 9 categories of showdown hands available. In this poker hand ranking guide, we’re going to introduce you to the worst showdown hands and make our way up to the best showdown hands.

A straight flush is completely determined once the smallest card in thestraight flush is known. There are 40 cards eligible to be the smallestcard in a straight flush. Hence, there are 40 straight flushes.

In forming a 4-of-a-kind hand, there are 13 choices for the rank ofthe quads, 1 choice for the 4 cards of the given rank, and 48 choicesfor the remaining card. This implies there are 4-of-a-kind hands.

There are 13 choices for the rank of the triple and 12 choices for therank of the pair in a full house. There are 4 ways of choosing thetriple of a given rank and 6 ways to choose the pair of the other rank.This produces full houses.

To count the number of flushes, we obtain choicesfor 5 cards in the same suit. Of these, 10 are straight flushes whoseremoval leaves 1,277 flushes of a given suit. Multiplying by 4 produces5,108 flushes.

The ranks of the cards in a straight have the form x,x+1,x+2,x+3,x+4,where x can be any of 10 ranks. There are then 4 choices for each card ofthe given ranks. This yields total choices. However,this count includes the straight flushes. Removing the 40 straightflushes leaves us with 10,200 straights.

In forming a 3-of-a-kind hand, there are 13 choices for the rank of thetriple, and there are choices for the ranks of theother 2 cards. There are 4 choices for the triple of the given rank andthere are 4 choices for each of the cards of the remaining 2 ranks.Altogether, we have 3-of-a-kind hands.

Next we consider two pairs hands. There are choices for the two ranks of the pairs. There are 6 choices for eachof the pairs, and there are 44 choices for the remaining card. Thisproduces hands of two pairs.

Now we count the number of hands with a pair. There are 13 choices forthe rank of the pair, and 6 choices for a pair of the chosen rank. Thereare choices for the ranks of the other 3 cardsand 4 choices for each of these 3 cards. We have hands with a pair.

We could determine the number of high card hands by removing the handswhich have already been counted in one of the previous categories.Instead, let us count them independently and see if the numbers sumto 2,598,960 which will serve as a check on our arithmetic.

A high card hand has 5 distinct ranks, but does not allow ranks of theform x,x+1,x+2,x+3,x+4 as that would constitute a straight. Thus, thereare possible sets of ranks from which we remove the10 sets of the form .This leaves 1,277 sets of ranks.For a given set of ranks, there are 4 choices for each cardexcept we cannot choose all in the same suit. Hence, there are1277(45-4) = 1,302,540 high card hands.
