Does a straight flush beat a full house?
Yes. A straight flush beats a full house in poker — every time. In the ranking of 10 hand categories, straight flush is #2 and full house is #4. Categories are compared first: even a five-high straight flush beats aces full of kings — the category always decides first.
Five cards in a row, all one suit.
Three of a kind plus a pair.
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 a full house appears in 0.144% (3,744 combinations). The harder a hand is to make, the higher it ranks.
Does a full house ever beat a straight flush?
No — never. The category comparison is absolute: the highest possible full house still loses to the lowest possible straight flush. Ranks inside a category only matter when both players hold the same category.
