Trevor,
I'm afraid the equation means nothing to me. Mind you if it explains how to convert the contents of my dustbin into chateau neuf de plonk I might make a bit of an effort.
No cost involved, and the new version that they have created, which is called "Kings Cribbage", is a brilliant variant on an old classic. If you have a go, try that one out at some point. Might see you there at some point.
PezBuin,
Thanks for the cribbage info. By the way, you have to watch Trevor. When he says salad sandwich, he means his interpretation of the government's 5 a day advice. In his case it means 2 cans of super-strength lager and 3 bottles of wine.
