Many profitable players plays a little bit different from each other, some players more agressive others more passive, but IMO that is just a little little difference, because what make a player better is the skillful to do good choices and it could mean that exist one single correct action for every single hand in poker and that differences are because we, humans, are uncapable to process all data and get an aswer. There will be ocasions when we have to be agressives, others passive and we have to be ready to evaluate them.
