Can an Ace be low in a straight?
I was under the impression that, in Texas Holdem, "Aces are always high". However, I have been playing online and I noticed that aces are used in a low straight (A, 2, 3, 4, 5). Was I mistaken that "Aces are always high", or is the online app that I have been using in error by using aces as low card in a straight?
Aces may indeed be used as low in a straight in holdem. A2345 is the lowest possible straight, also sometimes called a "wheel." In any other context, aces will be ranked higher than other cards.
Also straight flushes: A2345 suited beats quads, but loses to 23456 suited. All poker games using traditional high hands recognize the wheel as a straight, except "Deuce to Seven" (aka "Kansas City") lowball. In 2-to-7, a wheel is just A-5-4-3-2 high, thus beating any other A-high, but losing to K-high.
Note that `23456` is a better straight than `A2345` whose value compared to other straights is ranked by the `5` and not the `A`.
@Paulpro Hence my wording describing A2345 as the "lowest possible straight."
@ChrisFarmer Yea, your answer is good. The note wasn't intended for you. I was just providing additional clarification, for the OP or any other reader, by giving an example comparing it to the next lowest straight.
I once played pai-gow poker, A pit game where your playing against the house, I had a king high straight, the dealer had a wheel, they said the wheel won because it was ace high. I just left and never played the game again. In home games and casino table games you may want clarify.
