So I have been playing poker for around 3 years, only seriously the last 1.5 - 2 years, my brother has also been playing for 1-2 years, we are both making profit (not much atm but it's always increasing). We are both very serious about poker and are hoping to do this long term.
Our third (oldest) brother has played a bit of poker like a year ago and seems to think there's nothing to it, he knows nothing about positioning, bet sizing, BRM, ranges, anything at all but seems to think he knows how to play poker well. When we say stuff to him about positioning he seems to think it doesn't matter. He has no idea how complex poker is, he thinks it's a simple ABC game... We just want him to sit down with us for a few hours whilst we try to explain more complex poker concepts but he won't listen... He is a typical fish.
It is incredibly frustrating to know what I know and then to hear him say this. Has anyone got any good suggestions to how I can convert him? Any videos/articles I can show him?
Sorry if something similar has been posted before, thanks.
