Silver Level
Not much natural about it - you have to do it on purpose. What you have going for you is Level 1 and 2 becomes less effort after a while which allows you to focus on it.
Best exercise is to practice it in the hands you are not involved with. Pick the lead bettor and try to figure out what he is thinking about his opponents.
When you actually do it in your own hand it requires some very objective attention to your own actions. Best to make sure to ask yourself this question before any action - "If I (action here - call, raise, check), what will that cause my opponent to think about what I am doing?" Then you can consider modifying your action.
Question: can you think at Level 3 about a hand your not involved in when the other players could only be Level 1 thinkers?
