Position is more important than the cards. It can normally tell you if they have anything or not. I always like the have 2 shots and alot of people call the first time but not the second
Playing in a good position will always be a good advantage .... I would say that the best way to win a bluff is to do it only if you are.playing the hand against one or two villains ... if the villains call is a good time to Try to bluff ... make an aggressive bet and we'll see what happens ...!
