As a card game expert with a deep understanding of poker and its various hands, I'd like to address the question about the sequence Q-K-A-2-3 being a straight. In poker, a straight is a hand that consists of five consecutive cards of different suits. The cards must be in sequence, and there are no gaps between them.

To begin with, let's clarify the different types of straights. A straight can be either the lowest possible sequence, which is A-2-3-4-5, or the highest possible sequence without a gap, which is 10-J-Q-K-A. The Ace can act as both the high end of the sequence in the latter case or the low end in the former case. However, there is a specific rule that a straight cannot have a sequence that includes both an Ace and a King without the intermediate cards filling the gap. This is because the sequence would be broken by the lack of a Queen, and thus, Q-K-A-2-3 does not constitute a straight.

Now, let's move on to the other poker hands mentioned for context. A flush is a hand where all five cards are of the same suit but not in a specific order. This hand ranks higher than a straight but lower than a full house. A full house, on the other hand, consists of a set of three cards of the same rank and a pair of another rank. This hand is higher in ranking than both a flush and a straight.

In conclusion, the sequence Q-K-A-2-3 is not considered a straight due to the absence of a Queen, which breaks the consecutive sequence. It's important to understand the rules of card sequences and the hierarchy of poker hands to correctly evaluate and play the game.

An Ace can be either the low card or the high card in a Straight, but you can't build a Straight between a King and a Two. In other words, A-2-3-4-5 is a Straight, and so is 10-J-Q-K-A, but Q-K-A-2-3 is not. Just above the Straight is the Flush: five cards of the same suit, with any value. Next is the Full House.read more >>
