there are some decent players i've noticed, where i've taken notes on that are "know-it-alls" and they do it because sometimes it tilts people. i've been guilty of "haha...haha! HAHA!"ing to people sometimes when i'm drunk but i try not to, its not really my style. in real life...i'm mostly friendly with a chance of asshole...but at a poker table...i'd really like a forecast of me just being friendly. we've all probably had our moments, but that's just in our nature. there are several mediocre players who act like they know it all, maybe they read a book or something...i don't know. i've noticed lately in those fun steps at carbon since i'm playing like 6 at a time, someone will point out that i'm not playing in the one i'm card dead...and a few times, i realize they're raising my blind with any two cards, and then saying "see?!?!! he folds nonstop!"...best thing to do is not say anything, because usually when i'm not playing much, i've all ready doubled up and only playing top hands cause they're all such donks anyway...that's the same know-it-all who will call you down with nothing later on because he feels its his duty to remove you. you have to just distinguish what kinda know it all you're dealing with. is this one who's decent and uses his mouth as a weapon, or is this one who's lame and tilt-tastic? it does feel pretty shitty though, if they knock you out, but that's a risk you have to be willing to take at some point.
there's another kind, i should probably bring up. we've all met them. they think they're a jack of all trades...the guy who has an opinion on everything...the guy who's a pro on every single topic that comes up. you hate when he's at parties...or any conversation with anybody cause he butts in and is all like "no man, that's not how...bla bla bla"...that guy is full of crap too. and there's also know-it-alls that i best know how to deal with, like my brother..the really insulting kind....the kind that graduated 2nd in their class at va tech type....yeah, they may be smart...but their head is blown up way too big...i may have flunked out of college cause i got bored and was lazy but that doesn't mean i didn't come from the same sack of genes. you just have to find the things you truly know more than they do and exploit them when necessary.
