Does a flush beat a straight?
Yes. A flush sits directly above a straight, and the reason is that it comes up less: one hand in 33 against one in 22. It is the most commonly missed pair on the ladder, because a straight looks harder to make than it is.
Does two pair beat three of a kind?
No. Three of a kind beats two pair, even though you have four cards paired up and they only have three of a kind. Cards are not counted: the whole five-card hand is compared, and three of a kind turns up five times less often than two pair.
Is ace to five a straight?
Yes. The ace works at the top, as in ace, king, queen, jack, ten, and at the bottom, as in five, four, three, two, ace. That second one is the lowest straight there is and loses to every other. What never counts is wrapping around: queen, king, ace, two, three is nothing.
Does one suit beat another?
No. The four suits are worth exactly the same and never break a tie. A suit is only good for two things: making a flush and making a straight flush.
Do I have to use both of my cards?
No. You make your hand from the best five of the seven you can see: your two cards and the five in the middle. You can use both, one or neither. When you use neither, the five in the middle play by themselves and the pot usually gets split.
What is the highest hand in poker?
The royal flush: ace, king, queen, jack and ten of one suit. It shows up about once in thirty thousand hands, so there are players with years at the table who have never seen one. Nothing beats it, and two royal flushes split the pot.
