It is a common misconception that flush is more likely to hit. If you also believe that to be the case, then you are wrong. Well, maybe you are right, but it depends on which perspective you look at it. Let me explain.

As long as you start counting the hand from preflop, then you will hit the straight more often than flush. But if you have a flush draw on flop or turn, then you will hit a flush more often compared to when you have an open-ended straight draw, and you hit a straight.

There is a reason why flush has a higher ranking in poker than straight. It will hit less often. Look at this chance to win a straight and to hit a flush – from Wikipedia.

You will hit a flush every 0.20% of the time. So once every 509 hands. While you will hit a straight about 0.40% of the time or once every 255 hands, so you will hit almost 2 straights for every 1 flush that you hit.Table of Contents

Why is it easier to make a flush than astraight?

But after all that I have written, why is it easier to hit a flush than a straight?
Well postflop, if you hold a flush draw, you have more outs to hit the draw than holding the open-ended straight draw and hitting the straight. You will have 9 outs to hit a flush on the flop or turn if you have a flush draw.
From flop to the river, we have 9 outs twice to hit a flush, which is roughly 38%, from turn to the river we have about 18% (9 outs once). On the other hand, if you hold an open-ended straight draw, you will have only 8 outs to hit it.

What many people are forgetting is that you will get the flush draw less often than you will open-ended straight draw. Getting a suited hand preflop doesn’t happen super often. You will have a flush draw on the flop only 5.1% of the time.

One thing that is often neglected is you not accounting in the times when you have a gutshot, and you hit it. It seems it doesn’t happen often, but you will usually have 4 outs to hit a straight, which is around 16% from flop to river. Not something we should forget about. On top of that, there are also some double gutters, which also gives you 8 outs to hit your straight.

So only looking from the postflop perspective, it can feel that it is easier to hit a flush than a straight, but as I explained, that can often be misleading. Straight will happen more often.

Let’s say you usually play connectors and therefore your chances to hit your straight draw increase. You would have flopped 8 outs straight draw (either open-ended or a double gutter straight draw) about 10.5% of the time on the flop.

How often will an opponent flop a flush draw?

A player will have a flush draw on the flop about 5.1% of the time strictly math speaking and accounting in all the hands. But we know that players don’t play every single hand, and they are more likely to fold more off suited hand than suited hands preflop.

All this makes an opponent hit a flush draw roughly 10% of the time on the flop.

Which makes more money: Flush vs. straight?

As expected, flush will make you more money. In my case, not double the amount, but you will make more money with it. Why not the double, you might wonder? Well, if you have a straight, usually you will be willing to stack off with top straight or second nut straight sometimes 3^rd nut straight. But when it comes to flush, you will lose quite some money even if you hold a low flush, and it can be less than 3^rd nuts. On top of that, not many players will be willing to stack off with the top two or a set on a possible flush board, while the same players don’t have a problem committing with the same hands on possible straight board.

All this reduces your winrate by a little. But you, as you can see from my graph, will still make substantially more profit with a flush compared to straight. They are both great hands; it is just that a flush is stronger.

Now your winrate will, of course, differ a bit. If you have nut flush yo will win more than my 2,000bb/100 hands. If you have a lower flush, then it will be lower. Now sometimes higher flushes will beat us. A scenario of when we hit a flush, and our opponent also hits a flush is not that uncommon, and if you multi table, it will happen on semi-frequent occasions.

The same goes for a straight. Nut straight will give you the most money of any straight. You will still make decent money with 2^nd nut straight, just less.

Scenarios, where we hit backdoor straight, will be nicely profitable since it will be harder for an opponent to put us on a straight, as there was no apparent straight draw present when we started betting on the flop. If you want to read more about straight backdoor draws, I have this article I have for you.

What are the odds of getting straight flush?

Odds of hitting a straight flush is so low that it almost doesn’t make sense to write it in percentages. It is a 0.00139% chance you will hit a straight flush. This is 72,192:1 odds against hitting it. SO only once every 72,000 hands you will hit the second most powerful hand in poker.

What are the odds of getting a royal flush?

Poker Odds Flush Draw After Flop Game

Hitting a royal flush is even harder than a straight flush. The royal flush is the strongest hand you can get in poker. Your chances of hitting it are 0.000154% of the time, or once every650,000 hands (odds against of 649,740:1 to be precise).

I have been dealt quite many royal flushes in my poker career, and frankly, hitting one doesn’t feel special anymore. But I remember that when I hit it for the first time, I was ecstatic for some time. That is how rare the royal flush is.

Does a straight beat a flush?

Poker hand rankings go from strongest to weakest:

1. Royal flush
2. Straight flush
3. Four of a kind
4. Full house
5. Flush
6. Straight
7. Three of a kind
8. Two pair
9. One pair
10. No pair (high card)

You can see that straight doesn’t beat a flush, but it does beat many other hands, making it a powerful hand on right boards. When the board is not paired, and no flush can be present, then if you hold the highest straight, you will have the best hand.

What are the odds of getting pocket aces?

Chances of being dealt pocket aces are slightly less than 0.5%. Exactly once every 221 hands, you will get the rockets. The number of players on the table doesn’t matter. There are still 52 cards in the deck, no matter how many players are at the table.

If you wonder how often you can expect to win with AA depending on the number of opponents and different hands you are up against, then read this post.

What are the odds of an ace flop?

We all know it, that horrible feeling when you hope ace doesn’t show up on the flop, but it seems like it always does. It doesn’t always come. But you will see ace on the flop 42% of the time, which is quite often. But don’t worry on some occasions you will also hit two flushes, sets or straights yourself. That is why pocket kings have around 70% (and not only 58%) to win against Ax.

In the third part of the Paul Phua Poker School series on poker odds, Paul Phua gives tips on predicting the future to improve your present strategy

Would it not be wonderful to have the power to predict the future? It would certainly be easy to make money at betting! Film-lovers will recall how using a sports almanac from the future made Biff Tannen a rich man in the second Back to the Future film.
We can’t all have a DeLorean time machine, but in poker we have the next best thing. We have the ability to predict what is likely to happen in the future, and to change our strategy accordingly.
In the first two parts in this mini-series on poker odds, I gave tips on why odds are important, and how to calculate them using a simple magic formula. We have seen already how knowing our likelihood of winning will affect how much we bet. Now here is an interesting application in practical play:

How to play a nut flush draw

As I said in my video on the best pre-flop hands, a suited Ace has great potential as a starting hand, even if your kicker is low. An Ace on the flop often gives you the best hand, though be prepared to fold to opposition if your kicker is weak. And if you flop a flush draw, you are in a very powerful position – more powerful than many people realise.
Let’s take the starting hand shown in my video: A4 of diamonds. The flop comes K5 of diamonds, with a 9 of spades. Another player bets. First, do what you should always do when someone bets: work out what hand they are likely to hold.
There’s no strong straight draw out there; if he has a flush draw it’s worse than yours; sets are uncommon. You can’t put him on AK, as he didn’t seem that strong in pre-flop betting, so you reckon he has a K: maybe KQ or KJ. So he likely has top pair, and you have nothing – yet! But you have great potential. Let’s work out how much.

Count up your “outs”

There are nine diamonds left to come that complete our flush, plus three Aces to give us a higher pair: that’s 12 “outs”. Using our magic formula for calculating the odds, that gives us 12 x 4 = 48% chance of winning by the river. [Mathematicians say the real figure is 45% –the magic formula isn’t perfect, but it’s close enough.]
That’s a nearly 1 in 2 chance of winning the pot! Pretty good odds. But the great thing about poker is it’s not all cold, hard math. It takes strategy and psychology to decide how to play those odds.
Your instinct here will be to call, and hope to hit. That’s a reasonable strategy, and the more people who are in the hand, the better it is. You will likely take all their money if you hit your nut flush – thus being paid several times your investment.
But let’s look at another, more advanced strategy, one that is particularly valuable if only one other player is in the hand.

Re-raising for “fold equity”

Unless you are keen to keep a number of people in the pot, a great tactic against a single opponent is to re-raise rather than call. Re-raising gives you “fold equity”. That’s a fancy way of saying it gives you an extra chance at winning: if they get scared and fold, congratulations! You’ve won the pot with the worst hand. And if they call, you’re still a coin-flip to win by the river.
To have fold equity, your bet should be big enough to make them fold. Simply doubling their bet is almost never enough. Even a weak King is likely to call and hope you are semi-bluffing with a flush draw (which you are!), or that they hit two pair on the turn.
So how much do you raise? That calls for psychology: is this player a holder or a folder? Some people are “calling stations” who will call almost any bet with a pair. With a person like this, you may need to raise bigger. Either way, do it confidently. If you are relatively short-stacked, you can even shove all-in. Don’t worry! You are nearly 50-50 to win even if they call.

If they do call – what next?

Maybe they realise you’re on flush draw. Maybe they’re just stubborn. Whichever, your opponent calls you, and the turn card is a blank – it doesn’t help. What now?
Usually now you have no fold equity: if they called a re-raise on the flop, they will often feel committed to call a bet on the turn. And now you have only one card left to come, not two, so your chances of winning are halved to than 1 in 4.
Unless you are a very experienced player with a strong read that your opponent may fold, it’s not worth inflating the pot with what are now poor odds of winning. You want to check. The good news is, your opponent will be wary of you and will usually also check, so you get a “free” card to see the river.
To sum up: when you re-raise on the flop, you have maybe a coin-flip chance of them folding to give you a small pot; and a coin-flip chance of them calling, in which case you then have a coin-flip chance of winning a big pot. Three quarters of the time, therefore, you are winning with a re-raise!

Other flush draws

Let’s just look quickly at other flush draw combinations that you might not be aware of.
Two more outs: Let’s say there was a 4 on the flop rather than the 5, giving your A4 of diamonds a small pair. Now you have two additional outs (either of the two 4s still to come would give you three of a kind to beat his pair of Kings), so you are even better than 50%.
Three more outs: Or let’s say the flop came K52. Now with your A4 you additionally have an inside straight draw, giving three extra outs. (There are four 3s that would make a straight. One of these is a diamond and you’ve already counted that out in your flush draw, hence three extra outs not four).
Three fewer outs: The flush draw to beware of is where you have no extra outs, just the nine cards for your flush. The magic formula tells us that your chances then are just 9 x 4 = 36%, ie 1 in 3. It’s a big leak in less experienced players’ strategy to chase this kind of flush draw against a single opponent.
