i recently downloaded the free trial of the equity trainer for ace poker drills to see if it would improve my hand reading skills but im having trouble figuring out how to calculate my equity without knowing my opponents hole cards. and even if i could see the whole cards i dont think i would be able to come up with the equity in a percentage. if i could see the hole cards the most i could tell you is whether i am ahead or not. is there an equity formula that i am unaware of? and how do you pro players go about putting your opponents on a range of hands?
