Well, i recently found out that calling is nothing more than curiosity and according to psychology it is good be curious to certain extent. However, it doesn't help during session much.  Usually we know we are beat but still we want to call to see the actual result. It is sort of subconscious and i really want to get rid of it. Same goes for spew bluffs, curiosity gets over logic and the results is well, spew... So far pure practice hasn't really helped to overcome "curiosity"

So guys what you do in this kind situation? What is your though process, i pretty sure it has to be more than just we are beat we have to fold.
