If you’re playing online, at the same tables with the same regs, nearly every time you show your cards, they have the option to take notes, to help narrow your range in future
hands. You don’t really want them to have this info if they are the type of player that can can use this against you.
couple this with all the other stats they have on you after 500+ hands with you, you’re not fooling anyone. Yes, you may win against them sometimes, but
odds are if you play this way, they have much more of your money than you have of theirs
