End game practise

Hi all, I'm looking for a way of practising end game strategies. Does anyone know of a piece of software which allows you to specify the current score / board position so you can say I need this many, opponent needs this many and who is dealer? I guess another solution would be a problems page which focuses on end-game rather then discards as most seem to. Other ideas would be most welcome.
Many thanks,
Paul.

Paul, no there really is no software developed for that, but you've made a great point in trying to learn end game. I suffered for years...yes years...in end game play. Seek out Colvert's book or play as many possible games in real life and online against real people (don't play against computers they are too predictable.) Go to cribbage.org to find other resources.
