I would suggest to read Theory of Poker by David Sklansky
this book will answer all of your questions and doubts about everything related to poker
Seems that you have read the book..so would so share here?
Talk about luck vs skill in poker, I'd prefer to say 75% luck 25% skill. Yes the main reason is just because it is gambling
skill without Luck is nothing, but luck without skill is awesome. lol
He refuses to name poker as gambling if so he call it gambling with an edge
he talks about everything related to poker
starting from the odds that you can't change it in casino games but in poker you can double up even if you are 90% favor
he talks about the luck factor that will not affect your results in the long run
he said that good poker players are in a massive war with luck
when they feel that there opponents are drawing , they try to kick them out of the hand
my english is too bad to review his great book
if you are interested google the review of this book
or read it , i'm sure you will have a nice read if you love poker
I'm sure that David Sklansky is the best Author
he also have book in sportsbetting and general gambling
