The river card was a 5 of diamond, which gave me a steel wheel. A steel wheel is a 5 high straight(Ace, 2, 3, 4, 5) all the same suit(a flush).
It is both the nut low and a strong high hand. ADDITIONAL INFORMATION: In a high-low game in which straights and flushes do not count against the low portion of the hand, a steel wheel is the best possible hand.
The straight flush A-2-3-4-5 suited a five-high straight flush the lowest possible straight flush.
