I'm organizing a large charity "poker run" where I'll have hundreds of mountain bikers turning in 5 card hands to be ranked for handing out prizes. Instead of sorting them by hand, I need to punch in, for example, "participant 129" and their hand of, say, "KH, 5D, 5D, KH, KS" for a couple of kings of hearts, a couple of fives of diamonds and a king of spades. The trick, as you see, is that I have to rank hands considering the multiple decks. A five of a kind with all kings of hearts ought to be better than a five of a kind with various suits for the kings.
I know this is a long shot, especially since I'm no programmer/code writer myself. I'm hoping to find someone looking for a challenge and/or wanting to do something for the greater good of man (i.e. me and my charity).
