Figuring out equity

Could someone please explain to me how to figure equity vs a range or at least point me in the right direction. Thanks

try pokerstove they have a free download

Pokerstove works but in a real game if your multitabling your not going to have the time to put in hand ranges. You can usually have an idea of a % in your head when you make a play. If your having trouble coming up with numbers that are even close you can always run a few random hands on stove to get ideas beforehand.

Pokerstove is great but you have to do the analysis before you play. I put in the ranges for different situations and wrote down the results. When I play I scan my chart. I'm always adding different ranges/situations as I come across them. I find it worth the effort.
