Does a straight flush beat two pair?
Yes. A straight flush beats two pair in poker — every time. In the ranking of 10 hand categories, straight flush is #2 and two pair is #8. Categories are compared first: even a five-high straight flush beats aces and kings — the category always decides first.
Five cards in a row, all one suit.
Two different pairs.
How rare is each hand?
Rarity is exactly why the order is what it is. Out of 2,598,960 possible five-card hands, a straight flush shows up in 0.00139% of them (36 combinations), while two pair appears in 4.75% (123,552 combinations). The harder a hand is to make, the higher it ranks.
Does two pair ever beat a straight flush?
No — never. The category comparison is absolute: the highest possible two pair still loses to the lowest possible straight flush. Ranks inside a category only matter when both players hold the same category.
