you played the hand perfect. your friend is wrong.

just because you have a tell doesn't make him a better player. try and figure out what the tell is and then give him the tell at the wrong time and you'll make a lot of your money back.

one thing that helped me a bit is just doing random stuff on random hands, but stuff that i know i do on more crucial hands too.
i talk too much when i play with friends and give away way too much info. also, in the way that i act. i noticed some of the things that i do (for example, look down at my stack when i'm going to raise and then pretend i'm thinking about the hand, pretending i'm weak. lol). i don't mean to do this but it happens. so now a lot of the time i do the same thing and look down at my stack with any 2 cards, i'll then think for a bit, and then check or fold.

think about how you play your hands, think about how you act and talk when you have certain hands and then try to replicate that in other situations. this helped me get rid of some of my tells.

i've heard that phil ivey rolls his eyes around randomly on many hands so that players can't get a read on him. the movement of a players' eyes can say a lot about their hand and how interested they are in it.
