I like to play live poker. Sometimes I have the tanlet but not the chance
One of my Friends had a similar problem. He couldn't understand why he kept losing to other players, after he had followed my advice and read books on Poker and watched Videos and even though he won the odd game on-line, he couldn't score at all in Live events.
I asked him if he had fully read the book I lent him and he said "Yes, Cover to Cover"
"Well there's your Problem, They haven't!" What you need to understand is in Live games just as you do On-line you get Novice players that don't play Logically, and according to what the normal practices demand. You have to get a read on these players early on, and find the novices that will play any two cards and get lucky hitting the flop. This is one of the reasons the game characteristics change the closer to the bubble you are, and on the final Table.
As the adage says "The cream always rises to the top" you get better quality players rising to the surface the closer to the money you are. You have to adapt your game according to who you are up against, being cautious when up against the good players, and punish the weaker players.
I hope this helps in some way and Good Luck!
