I’ve just finised writing a 5 card hand evaluator (I’m avoding the ‘pkr’  
word since the spam filter won’t let me post when I use that word),  
using the algorithm found: [http://www.suffecool.net/\*/evaluator.html](http://www.suffecool.net/*/evaluator.html) (\<\<  
replace \* with the ‘pkr’ word, same in the next link \>\>).

You can download it from here:  
[http://www.btinternet.com/~douglas.marsh/\*.zip](http://www.btinternet.com/~douglas.marsh/*.zip)

Use the ‘eval’ method. For the purposes of this code a card is defined  
as an array where element [0] is a number 0…12 (0 = two, 1 = three …  
11 = king, 12 = ace) and element [1] is a number 0…2 (0 = clubs, 1 =  
diamonds, 2 = hearts, 3 = spades).

The lower the value returned, the higher-ranking the hand. Enjoy.
