[HesseJam]

I never show my uncalled hands because you give out information for free.

The information is not "look, I do not bluff" or "look, I push with a lot of hands" because your opponents should well understand that it could have two consequences: If, for example, you showed a strong hand you might push with a weak hand because they might believe that you are not bluffing or you might push with a very strong hand because you think they counteract to your "show-off" and believe you have a weak hand. Thus, they cannot interpret you show-off with regard to your raising standards and thus you cannot estimate their calling standards.
But they know you showed your cards for a reason, namely, that you want to manipulate your opponents.

This is the information you gave out for free: You want to manipulate your opponents which means that you are not playing a robotic first-level-thinking style.
