Is there a way that you can ensure being difficult to predict at Poker? For example, if you never bluff, people will eventually get to known that and it will reduce your ability to profit from good cards? Anyone there knows techniques or trick to avoid being easy to read?
The only technique that will work is to have a poker-faced and it can be done by practice and through meditation, I have seen people who practice yoga and they can have no feeling or expression at all if they want, practice makes perfect if you practice over a thousand rounds and you get to use having no expression at all, you can achieve that if you are dedicated to your craft.
