You would have those rankings precomputed beforehand. So you'd know A 2 3 4 5 is one straight, but its computed hash would have a higher ranking than 2 3 4 5 6 in the lookup table. The A straight might go to 735 and the 2 3 4 5 might go to 785 or something There is work to do in the construction of the list, but that happens once, and likely gets loaded from disk after it's created out of band.
